1 . The plate
Lost wax casting needs Laban , and Laban batch production version will need to suppress silver rubber mold . It is jewelry making process demanding process , requiring the surface of the prepared silver plate , hollow parts and trace back clean , reasonable structure requires each part of the silver plate , the position of inlaid stones
Size accurately trace, some also require pre- processing of the mosaic site . Ready silver version after the lost wax casting process can enter .
Currently plate-making process used are: hand- carved Laban , computers and hand -made silver carving Laban version , three processes have advantages and complement each other .
Paraffin hand carved carved out of Laban that design drawings , and then use the lost wax casting method poured silver edition ; computer carving Laban Unlike hand-carved wax is that it is through the combination of 3D computer software and spray wax machine make wax modeling, using the lost wax casting method poured silver version, and hand-made
Silver Edition model is the master plate making handmade designs directly on the map . Laban -plate engraving by hand speed, carving wax process modifications easier , tool wear is relatively small and is widely used , but because in the production of hand- carved claw nails Laban rabbet is difficult , then it will use to make up handmade silver version .
Handmade silver inlay mouth is in the production version that is convenient , good quality, especially in the production of parquet port and a number of different types of Prong .
2 lost wax casting
Commonly known as lost wax casting die down . Currently jewelry is an important means of production.
2.1 suppress plastic mold
Notes and plastic mold pressing process :
1 ) , the die box and raw film to clean , do not touch the surface of the film students .
2 ) to ensure that no adhesion between the original and rubber , priority should be to use the silver version , should be silver-plated copper .
3 ) determine the appropriate curing temperature and time , basically in line with a functional relationship between the two , and the thickness of the plastic mold , the complexity of the original width and about . Usually die temperature to about 150 degrees , if the thickness of the three layers of plastic mold (about 10mm), generally curing time is
20-25 minutes, if there are four layers ( approximately 13mm), the curing time may be 30-35 minutes. And so on. At the same time the complexity of the curing temperature also has a relationship with the original , as the original complex , small, should reduce the curing temperature and longer curing time .
4 ) , when the die to ensure there is no gap between the original and raw film. Using plug, wrapped , fill voids bit way on the first edition , and insets recess bits, etc. fill , fill up with rubber Suixiao , press firmly with a sharp substances ( such as forceps ) .
5 ) , first preheat . Quickly removed to the curing time after plastic mold , plastic mold requires good overall pressure without distortion , smooth, do not skew the waterline , it is best when it is not hot to cool , you can be hot with a sharp knife to open plastic mold operation.
2.2 open plastic molding and injection molding wax
2.2.1 open plastic mold :
Technically demanding . Because open plastic mold direct impact on the quality of wax and metal blanks . Open plastic mold tools have relatively simple scalpel , forceps , scissors, needle-nose pliers . Plastic mold usually legs positioning method , that is . Out of the plastic mold with four legs coincide with each other
Partially fixed , there is a straight line between the legs cut , there is also the curve cutting . Open to note that good plastic mold inspection, can not have any defects within the plastic mold was broken flower as obvious , chipping , adhesion , etc., which may have resulted in defective wax , and therefore should be part of these defects
Repair , such as cut uncut position welding with welding Wax flower breaking , chipping areas and so on.
General mold in the following order : 1 pressure over the plastic mold is cooled to not hot, with needle-nose pliers to take the drain block , got me to focus shell plastic mold outlet up .2 to erect, from one side of the outlet of the knife , plastic molding along the four sides of the center line of the cutting depth of 3-5 ( can be adjusted according to the size of the plastic mold ) , cut the plastic mold
.3 Sides of the knife from the first cut of the first leg of the first of two straight edges cut depth of 3-5mm ( can be adjusted according to the size of the plastic mold ) , then tugged straight edges have been cut , along cut a 45 degree bevel, the beginning of the foot to form a right triangle , then the cut halves of the plastic mold
There should be a corresponding male and female foot triangle .4 mutual agreement in accordance with the operation of the previous step , followed by cutting out the remaining three feet .5 opened the first cut legs , cut with a razor blade balance inward along the midline ( if curve cutting curves according to certain rules should swing blade , draw scaly
Or wave -shaped section ) , while cutting out the side pulled plastic mold , fast reaches the outlet line to be careful with the tip gently pick open plastic mold, leaking outlet , then cut along one end ring ring ring outer ring , until the ring inlaid flower heads and mouth .6 cutting flower heads , which are more difficult to open plastic mold
And complex steps , if the mouth is the main stone inlay inlaid claws , cutting the flower heads should be cut along the axis of the flower head side two claws , and then cut to the other side of the ring outer side of the end face of the flower until the cut to the outlet location. Then plastic mold has been cut in half , but still can not remove the silver version .
7 left rabbet cutting , plastic molding part of the flower head . In the primary and secondary sides of the stone inlay stone mouth intervals along the outside of the main stone inlay mouth has been cut two claws axis cutting, until the other two claws symmetrical : the mouth and then along the main stone inlay remaining outside of the cut in one direction , just opposite the cutting surface , the main
Stone inlay mouth upright shape. Then in the main stone inlaid stone inlay mouth mouth and claws , vice roots crosscut knife , make flower head into two parts. Opened the severed part , observe whether the elongated plastic wire ( usually a hollow portion of the hole and the flower head deputy stone inlay mouth formed ) , if you should cut off
. 8 Remove the silver version , between the silver version and observe whether the plastic mold plastic wire adhesions, if adhesions must be cut off. 9 open end . Deep along the entire circumference of the inner ring incision and inserts the mouth, flower head portion of the cut marks ( for not cutting through, remaining slightly concave rubber forming a shallow stretch marks ) .
Cutting marks along the position corresponding to the outlet , the cut 8-12mm in width along the long direction of the nozzle equal length close to the outlet . A similar case is formed at the bottom of the mushroom shape , the ring has an inside part can be pulled out from the bottom of the cut . Such plastic mold in jack
After the wax to smooth the wax removed.
Plastic mold of preservation of the environment should be low , and dark, but also to avoid oil, the impact of acidic substances. If you are using is not very frequent , the film could use a decade . But if you use frequently, usually not used for two years . Average service life of the film 2-3
Between years .
2.2.2 wax injection molding :
Plastic mold injection can be performed after a good wax to operate. Note should be taken of wax on wax operating temperature , pressure and other factors pressing film master .
Wax injection machine and the temperature of the heater so that the liquid wax is able to reach and maintain a certain temperature, typically the wax wax injection machine should be maintained at a temperature between 70-75 degrees, so that the temperature of the liquid to ensure the fluidity of the wax . If the temperature is too low, easy to fill liquid wax wax , wax residue resulting
Missing ; contrary wax temperature is too high , will lead to the fluidity of liquid wax . If the temperature is too low, easy to fill liquid wax wax , wax mold caused by incomplete ; contrary wax temperature is too high , will lead to an overflow from wax or wax from the wax injection gap at the mouth of the overflow , easy to form burrs or burns finger
. Wax injection machine cylinder pressure is provided by an external pump, wax-like plane more simple shapes with 0.5-0.8kg/cm? Pressure . Wax-like thin walls , inlaid stone -bit multi- bit and narrow the gap with fine
1.0-2.0 kg / cm?. Jack wax time : large wax-like 4 seconds , small pieces of wax-like 2 seconds.
Note Wax: wax injection before , you should first open the plastic mold , integrity checking and cleaning of plastic mold . If it is used in plastic mold , plastic mold should be the relatively small , especially at the beginning of a complex position spray dewaxing agent ( also sprinkle a small amount of talcum powder ) , to facilitate removing wax . Dewaxing agent
And talc are not used simultaneously, talc unusable too much care in order to avoid the wax surface roughness . Powder can shoot a piece of wax from 3-6 . Then to warm wax injection machine , open the pump, adjust the pressure and temperature.
Note wax when starting pump , check the temperature of the wax is between 70-75 degrees, check the air pressure and the rubber mold according to the complexity of a good tune wax pieces wax injection time, and then with both hands in plastic mold clamping jaws , attention distribution of finger pressure should make plastic mold evenly ; align the plastic mold outlet
Parallel implementation of wax injection nozzle , top prison after wax injection nozzle does not move his hands , as shown , together with their feet tread lightly wax injection and immediately release the switch when the wax injection machine indicator lights from yellow to red , then changed a green, wax injection process has been completed, plastic mold can be removed from the mouth next to the wax . By wax injection
The order put plastic mold , do it when the rubber mold after 6-7 months , you can open the first plastic model ( if plastic mold bottom , should first pull out the bottom of the mold ) , remove the wax , and so on . Modulo to note that the way to avoid pieces of broken and deformed wax , wax removed after careful examination ,
If a lack of edge , breaking jaws , deformation, or more serious bubbles flash problem belongs wax such waste . If a very small number of defects in the wax should be trimmed.
1 , wax injection materials : blue model paraffin, melting temperature around 60 ℃, wax injection temperature around 65 ℃.
2 , wax injection tool : wax injection machine, there are two kinds of pressure and vacuum . Vacuum can vacuum the first film , the film again wax injection ; pressure -type wax injection directly to the film .
3 , note
1 ) Check the integrity of plastic mold and cleaning , can use dewaxing agent.
2 ) , preheated wax injection machine , open the pump, adjust the pressure and temperature. Temperature is too low , the wax liquid wax easily filled , resulting in incomplete ; temperature is too high , resulting in an overflow of liquid wax , easy to form burrs or burns. The machine is generally maintained at a pressure between 0.5-0.7at.
2.3 finishing wax and wax tree species
Dressing wax : Generally, after removing wax wax injection molding or less , there are some problems. For flash, multiple edges , clamp marks, flower head is not clear , or take the side pieces with a scalpel and other defects can repair light ; For trachoma , broken jaw Wax can be used welding repair welding ; holes may be unreasonable
To penetrate with solder pin ; may be corrected at 40-50 ℃ in hot wax model of the deformation . If the right hand-inch to direct change in the repair wax ring finger .
Wax tree : the production of a good wax in a certain order , along with welding wax welded circumferential direction successively layered on a wax stick, tree shaped like trees eventually get to wax tree .
The first step is to wax tree wax dip stick the head of some melted wax , hot inserted into the recessed hole in the chassis ;
The second step, layer by layer to wax on wax stick welding . Usually the head starts from the wax stick , down from the top of this method to prevent droplets of melted wax on wax falls welded avoid unnecessary rework
Wax tree wax basic requirement is to be arranged in order, neither between the contact , but also as many will wax tree wax welded to meet the needs of mass production .
In addition, the tree should be preceded wax rubber chassis weighed again finished wax tree weighing, weighing the results of the two can be derived by subtracting the weight of the wax tree. The weight of the wax tree density in accordance with the proportion of paraffin wax casting metal conversion weigh the metal, can be estimated
The amount of metal casting .
2.4 baked gypsum plaster and filling
Filling plaster : a good wax tree species will put together even stainless steel tube chassis ; the corresponding weight of gypsum powder and water ( ratio generally 2-2.5:1 water with distilled water ) and stir into the gypsum slurry, for the first time vacuuming after the gypsum slurry along the inner wall of the steel bell slowly injected , should not be
Gypsum slurry poured directly in wax tree. Not over until the gypsum slurry wax tree about 1cm, a second vacuum. Then allowed to stand for 6-12 hours to ensure solidification of gypsum .
Baking plaster : plaster mold baking is important to ensure the normal casting process , his role is mainly dewaxing, drying and casting insulation.
18K gold with baking , for example, dewaxing temperature 0-350 ℃, holding time of 2 hours ; drying temperature of 350-700 ℃, holding time of 2-3 hours ; casting temperature of 50-600 ℃, holding time 1-2 hours.
The roasting process is generally : first furnace preheated to the initial temperature, the plaster mold downwardly into the furnace outlet to facilitate outflow of liquid wax and evaporated. Thermostatic temperature zone at the start of an hour later , at 1-2 hour intervals and gradually heating thermostat . Note heating ( or cooling ) speed
Degrees should be maintained and then 100-200 ℃ / hour, or excessive heating plaster mold is easy to form cracks , plaster mold could cause serious damage or scrapped. Warming caused by leaving too slow and easy to wax or plaster mold is not completely dried , affecting the quality of castings . Baking time depends mainly on gold plaster mold
The size and complexity of the tree can be adjusted according to the specific circumstances .
2.5 Melting , casting
When the plaster mold baking nearing completion, with a good start melting the gold and keep the molten state. Subject insulation plaster mold is completed, the Goldwater injected from the outlet to complete casting . Two common methods are vacuum cast suction casting and vacuum casting machine induction centrifugal casting machine casting .
Fried 2.6 plaster mold wash , wash and cut the rough
After the plaster mold casting high temperature state , the natural place for 10-30 minutes after removal from the casting machine , and then carried into the cold water to wash bombing .
Due to the contraction burst plaster , remove the gold tree , steel brush to chunks of plaster , into 30% hydrofluoric acid in water for 10 minutes, then clip out , rinse ; cleaning with high pressure spray gun gold tree removal the remaining plaster , clean surface until golden tree
.
Gold jewelry tree cut along the bottom outlet , dry, weighed to deliver storage or the next process.
3 and inlaid jewelry they die
3.1 Executive jewelry touch technology
1, what is they die ? After touching is the executive lost wax casting , inlay craft link before . Due to shrinkage and deformation resulting casting , molds often have the appearance of trachoma, draped peaks , heavy side , depression and even fracture and other issues, the need for repair and calibration. If the bracelet is also
Make one buckle welding forming, bracelets and chains have processed Ap Lei class system, is a tongue like a duck metal shrapnel for Zuohuo buckle.
2 , the process execution touch : touch the contents of the Executive welding and repair welding , rational use of the rasp of sandpaper and tire usage , typing die. The process sequence is usually : shaping, cutting nozzle , filing outlet - check and repair welding cracks , trachoma - Correction shape ( used rasps , saws
Cutting , etc. ) - the dwarfish filing of light - light oil Broacher - pot alum water - playing sandpaper ( or tire ) - Typing mode ( laser type printing ) .
3.2 of rock and stone with
3.2.1 Look Stone
Look for stone mosaic preparation. Come in to buy a large number of diamonds or stones sent customer orders , there will be a lot of problems . Stones come in to buy a lot of clarity is low, there is crack, there is missing, there are flowers, there are black spots , there are Mongolian . There bifida beat in fear when the mosaic , stone must see this
These split zoned out in red to remind inlay masonry careful ; If the crown or waist black specks, small waist with a small gap or crack feathers have zoned out , to remind the package inserts inserts masonry using methods to cover ; big missing, there is a large crack, Mongolia must have a clear written
So that at the end of insets, investigated the responsibility to examine the goods when , because it is easy to engage rotten stone mosaic , stone and polished Shiyou may engage Mongolia ; customers to stone may be a problem on the genuineness of the stones , especially some demolition of a small stone with a stone , it may be mixed with zircon , a timely
Detection and timely reports.
Customers will usually let you get some stones to identify the level to which they choose to do the inspection station certificate because the country seized demanding , while the rest will be relatively loose some , some of the lower level of the two edges can touch the stone a poor level meeting , particularly the difference between VS and iS , especially in business
Important , VS is known to have levels of diamonds, but there is no level below the IS , prices vary widely . It ’s time to see the stone can not simply look at the level , because the customer does not see the diamond , he said the diamond is likely zircon.
Under no circumstances any precision instrument , But a magnifying glass to distinguish between diamonds and ten Fangzuan , have considerable experience in the job. Among the many Fangzuan , the emergence of a large number of commercial zircon , followed sometimes see Moissanite , but because of the obvious double shadow , Moissanite remarkable tolerance
Easy to identify. Zircon be two in business , one is made in China , one is imported goods. Domestic zircon cut more than good, common edges smooth, a little less than each of the ridges converge on extra thick lumbar facet too big drawback on fire color and brightness also significantly less than diamond
. While imports zircon can almost reach the point where real ones , regardless of imported zircon and high quality diamonds are similar in cut and color of fire . Loose lines for obvious method is simple, the lines that the law down on a stone table in a straight line , zircon will see the bend in the pavilion
Curved lines, while the diamond invisible lines. In most cases this method is efficient and effective , but if you do not meet the standard of cut stone , such as the pavilion depth is too shallow, light leakage serious diamonds, other methods will have to be considered comprehensive . Experienced teacher alone can distinguish color and light on fire
To accurately distinguish between diamonds and zircon, Zircon colorimetric lamp rendered in warm colors and white diamonds obvious bright, calm and more in ; pavilion zircon observed by tenfold if there is a mirror, look through the table blue, yellow reflective , most of the time because zircon leaked will see the ridge of the pavilion was
A white lines , if there are gaps heel section , also saw bright white point, and will not appear colored diamond internal reflection, there will be no light leakage caused by white lines. There are a lot of small with about one minute drill in the business , in particular, is likely to split the stone mixed with zircon. Because the stone is too small lines
No use of the law , then we should from the color, cut and color of fire , the light on the comprehensive judgment . If the color was yellow , the standard 57 -cut surface , there may be a diamond , because pellets do not use more than the standard zircon round brilliant , and zircon are white hue ; lamp diamond in colorimetric
Now the incomparable shine , mercury texture, while zircon is now dim lot.
Stone will be seen in the factory lot of terms to describe clarity , such as: the flowers are used to describe the clouds and strong inclusions, black spots refers to black enclaves , while white is the edge crack caused by the white reflective or white flocculent inclusions, white stone mask is due to the car caused by careless burning stone , and significant hazy muddy
Turbidity and more.
For clarity grading will be the first to distinguish between internal and external dirt enclaves . 1 ) the difference between the body and the external transparent bag dirt . Inclusions within the diamond host due to differences in the refractive index of the diamond is particularly bright and visible , while the external dirt is bleak and more ; diamond back inside most shadowy enclaves
Like , shaking diamond image moves between several facets or disappear, while the external image of dirt does not move ; 2 ) black inclusions and external dirt distinction. Black enclaves looked dim significantly through the table a lot , just across the glass to see things , if it is on the table then dirt
Fresh significant uncertainty .
Second, the high level of diamond clarity , healing fractures and small needle -like point is extremely difficult to observe , there are many cracks in the crown for the vertical extension , looked carefully in a straight line , this line often hard to find . Particularly low color grade stones , cracks can easily be concealed color ;
Small needle -like point is elusive , endoscopic times you do not know where it will , maybe not aligned with the light , it will slip away . Look for these situations requires to constantly move the stone head , while shaking diamond exchange viewing angle , and fully observe every level of the diamond, each
A site, can not have missed.
3.2.2 With Stone
After reading the stones are sent back to the Ministry with stone with stone. Department will feature stone size, color , clarity grade diamonds plus one distinguish different , depending on the size of the metal bracket rabbet corresponding stone put up compared invisible setting in which with stone has some technical content. With stone in the process,
The main problem of the next single customers. Customers may be sent stone inlay mouth size that much difference, if it is too large stones , stones will be exposed gold surface ; If the stone is too small , gold will wrap stones , both of which will drop at the end of the beauty of jewelry and service life ; several
Does not match the number of customers asked to send the stone and metal , resulting in not with stone ; Some customers may send the stone color is not uniform , for example, a pair of earrings may be a grain of yellow grain white two tablets of stone , stone bracelets have on some yellow white , making it impossible with stone.
3.3 mosaic
Insets main setting techniques are: pour nail set , Prong , nest inserts , nails inlay , Channel Set , nails inlay , package inserts , etc., insets learning process is generally simpler to start nailing down inlaid start , all inlaid process as outlined below:
3.3.1 pour nail set
Pour nail set nail is pressed to the existing stone on stone inlay for fixing mouth . This is the insets in the simplest, most basic setting techniques .
1 nail down the steps inlay
( 1 ) will be required inlaid stone on the rail station , according to the size of the different stone be separated .
( 2 ) Subject to the Shang Hao wax inlaid goods dominated by Taiwan with his left hand stuffed fixed .
( 3 ) point tweezers dip inkpad stone and stone insets on the position of the stone. Such as stone insets position than large, according to the thickness of the stone with a peach umbrella pin or needle open position until the rabbet bit the same with a large stone .
( 4 ) According to the size of the stone , choose one with inlaid stone as large UFO , stick nails into the UFO oblique angle first , then slowly righting the car rock bit .
( 5 ) point tweezers dip inkpad stone , inlaid into the stone ramp into the mouth , the stone must be slightly lower than the workpiece surface, and then clamp the pressure of being stone , stone UFO vehicles must fall into the pit , if you see the stone flat , then the beads with a suction from the bottom up to the stone edge of the nail head push , nails need to paste stone. Such as stone injustice,
You need to use UFO tilted in the opposite direction and then lower the car until the flat stone . If the stone from the nail peace, you need to use UFO tilted in the opposite direction and then lower the car until the flat stone . If the stone is too far away from the nail , the available pressure nearly flat shovel , using suction nailhead beads affixed to the stone and the nail head under pressure, can not be designated lace and light gold
Bit .
2 inlay nail down requirements
( 1 ) good stone inlaid stone can not have a ramp , hurling stones , turquoise, rotten stone and so on.
( 2 ) the level between the stone and the stone should be based on the shape of goods may be, the same line can not occur between the phenomenon of uneven stone and stone.
( 3 ) light golden stone around Phnom Penh bit and can not scratch .
( 4 ) nailhead be rounded, not flattened and nail edges can not appear gold feces .
( 5 ) nails can not be too long or too short , too long to easily hook clothes , too short and easy sling .
( 6 ) must be classified before the stone mosaic and the first observation of the thickness of the stone , shape , position in the open pit .
( 7 ) whether the formation of stone observation method is to place the stone surface with inlaid mouth for comparison. The stone surface seen as a straight line , respectively, from four directions with insets for comparison, if the stone flat parallel .
( 8 ) whether the observed rock formation, from the overall shape of the workpiece to observe .
3.3.2 Prong
Prong features: the greatest degree of prominent gems for round , oval , square, teardrop-shaped , heart-shaped and other shaped egg noodles or faceted gems. Prong flaw: the mouth is usually due to the production of non-standard or inlaid precious stones cut non-standard result .
( 1 ) , open at the end : that the pavilion facet gems exposed.
( 2 ) , exposed side: gemstone inlay mouth exposed.
( 3 ) , broadside ; refers gems inlaid waist is larger than the mouth , jaws bent back easily damaged stones.
( 4 ) , slatted : gemstones inlaid waist is smaller than the mouth .
Prong is to fix the stone claw claw claw can be divided into round , square jaw , triangular claws, jaws finger , horoscopes claws, six claws, four claws , claw , two claws , single claw , claw , etc. in public .
1 Procedure
( 1 ) degree position : as the location of the stone insets into place, pay attention to pay attention to the size of the thickness of the stone , as appropriate , based on the size of the stone on a drill or UFO claw grip position with a suitable vehicle umbrella , the grip of height can be depending on the thickness of the stone .
( 2 ) open parking spaces: figure, if the stone is larger than the rabbet bit , use an umbrella or peach diamond drill underbody gold, so quite a bit of stone and insets . Then the appropriate action to be carried out according to the type of stone , such as egg-shaped stone on the use of open pit drill bits, etc. umbrella . Should open pit and depth and height of the bit is determined by a
Cause , claw feet and tube position is not the car empty intersection .
( 3 ) jaws : James inks points with pliers stone insets into the first bit longer inclined to push positive tweezers , flat stone with a needle nose pliers if the symmetry were slightly clamping claw , the claw attached to stone , and then the neighboring claw of two positive clamping , as . not make note when the stone jaws bit skewed, can not cause the clamp marks too, otherwise
Side affects subsequent execution process .
( 4 ) claw scissors : scissors with pliers jaws , while cutting claws, claw hand pressure head , avoid bombs go head cut paw paw , as shown , note length claws , long time when you need to file , too short and easy breathe stone.
( 5 ) filing claws : After cutting claws, use triangular file to file to meet high suction claw claw , claw after high consistency , and then file the claw inside bamboo trim to paste stone , and then rounding the outer claw . in order to suck and suck claw beads when filing claws , use the left thumb or index finger positioning , do not file the stone surface , as shown in Figure
( 6 ) absorption round claw : beads with a suitable suction suction claw , swing from inside to outside and evenly on both sides until the claw head round suction , suction paste stone, to the outside of the outer claw suck the same height , as
3.3.3 nest inserts
1 Procedure
( 1 ) point tweezers dip inkpad stone inlay on the mouth of the position of the workpiece , as
( 2 ) If the stone is larger than the rabbet bit , then drilled with a wave , bringing the rabbet bit slightly larger than the stone, and then use the flying saucer in the car a bit rabbet nest , as
( 3 ) tweezers dip inks stick stone along the pit bit rockfall subsequently observe whether the stone -bit level , if the stone uneven, observe the reason , if the end of the gold is too thick , have to use wave and drill bits , until the stone flat ; If the stone flat , then use the stone beads inlaid nest suck suck tight , you can not wear when playing quickly suck , suck a little rock steady after watching
Stone is balanced, if Shiping Heng Stone will suck tight,
( 4 ) steel pressure generated by the suction gold feces pressed stone , the gold feces Rhinestones , if uneven gold feces , then scoop out the excess gold feces , feces in solid gold with a needle .
( 5 ) when the wave drill parking , pay attention to the wave drill bit can not be biased
( 6 ) when the suction stone, absorbing beads chosen should be appropriate , too Bye breathe stone edge without gold, stone or stick is not too easy to delamination.
2 Operational requirements
(1) Before the first shape stone inlaid stone classification and observation , and then open pit size bits .
( 2 ) can not have a ramp stone, turquoise, rotten stone , high and low stone, hurling stones , gold feces does not stick stone and so on.
( 3 ) stone surface to be slightly lower than the gold surface .
( 4 ) Gold feces should be uniform, not too much, too little or uneven .
( 5 ) can not collapse the nest edge , or edges appear large , while small phenomenon .
( 6 ) the middle stone blocks shall not be partial
( 7 ) During the feces pressure gold hand to be, can not be Penh scratch .
