In recent years, the development of jewelry industry in China rapidly, jewelry has become increasingly popular among the. With the development of science and technology and people’s aesthetic standards continue to improve, life interesting alsocontinues to expand, the traditional commercial jewelry has been difficult to meet thepeople’s consumption demand, today’s jewelry

Be given more extensive deeper meaning. After trying to clay, silver clay Jewelry,jewelry design and jewelry produced fans generally use wax carving process as theprocess of the design ideas, wax carving process and has become the first choice forjewelry making DIY

. This paper will make a discussion on the basic techniques of jewelry wax carvingprocess.

Preface

If the jewelry as a small sculpture, then the process of wax curving process can be considered as the process of making sculpture. The use of wax carving process ofwax material has a certain hardness, while in the case of heating can be bondedfusion modeling method, can use additional type can be used

Modeling method of cutting type. So the wax material plasticity wax carving process is very strong, forming more convenient. In jewelry wax carving process can be divided into: basic techniques of shaping of wax material cutting, wax, wax finishing materialhollow and wax materials for fusion four aspects.

Cutting, wax material

The wax material cutting according to the different needs of the wax material bycutting method is different, can generally be divided into cutting and soft wax to cut hard wax.

(a) cutting hard wax

A hard wax hardness is relatively large, the viscosity of the material, in the cutting process if not generate a lot of heat wax chip is easier to fall off. A hard wax can be used to complete the cutting saw. Use vernier caliper or machine tools in the wax material shear mark cutting lines, then use the saw blade cutting along the marked line

The wax material separation. In a large area of cutting can be used in cutting bladespecial wax, wax brick can even use woodworking saw cutting is finished, the small scale cutting can use fretsaw metal processing, such as: insert claw jewelry fine partsand decorative parts of the cutting can

Hollow method in reference below.

(two) hard wax cutting note

In the premise of hard wax does not produce heat cutting easier, but if the cutting speed is too fast, too late to dissipate heat condition, under the influence of heat wax chip will stick together, at the same time to reduce the cutting tool, cutting efficiency,so when cutting by force

And the speed, do not blindly pursue speed.

(three) cutting soft wax

Soft wax texture soft, sticky wax, wax using a saw blade cutting chip tends to stick tolower efficiency, so the cutting blade is convenient to use soft wax. Mark with a bladecan be directly after the incision in the wax material.

(four) soft wax cutting note

First of all, soft wax lower hardness in the cutting is very easy to deformation, so in cutting soft wax is best can be placed on a plane above the soft wax support, for the soft wax ornamentation of the best first making wax material after cutting andornamentation. Secondly, the cutting tool to use when sharp soft wax

, blade and wax surface angle as far as possible to reduce, prevent during the cuttingmaterial away, pull wrinkled wax.

Either cutting method, wax material in actual machining process will have a certain amount of consumption, taking into account the casting shrinkage will have certain, so the processing of cutting is slightly higher than the actual demand, the generalallowance is about finished 15% (proficiency will be smaller).

(a) hard wax finishing

In a hard wax finishing can be divided into the dressing and the inner surface of the outer surface of the dressing, and both contain the plane and spherical surfacedressing, dressing. The most critical surface finishing is to use the tool with the. File is the main tool for surface finishing, and sometimes can also be used as needed

Some other tools, such as knives, needles and so on operation. Crane with a variety of wax carving needle is the main tool for treating the internal surface, can also be matched with the operation knife tool.

1, the outer surface of the dressing

Planar outer surface dressing is using the file will surface finishing blank is flat.Sometimes you can use crane with the needle to improve work efficiency. For example, the excess is relatively large, but not the use of wax sawing width, then you can use the crane with large needle to complete,

In the dressing of close to the level needed to use the file to fix.

2, the inner surface of the dressing

The main use of the inner surface of the dressing is a crane with a variety of needle.Plane dressing can be matched with various file or other tool. In the description ofgood mark line, using a large tooth needle or a large slotted needle marks along theline of the excess wax wax polish, from large to small conversion needle, the most

Will the corner dressing carefully, and then use the flat small flat file or tool will surfaceflat rasp. The corner part can use the square or triangular file modification.

3, pay attention to the problem of hard wax finishing

The correct choice of file and needle type. The models include file, file and the shape of tooth thickness, the wax material dressing is the transition from large to small toolstools. The tooth file is transition from large to small teeth teeth, so dress smooth surface.

(two) soft wax finishing

Soft wax easily deformed than hard wax, using smooth glass plates or other smooth surface rolling press tool can be trimmed standard. In the process of carving wax softwax is generally not used to make special formation, regular shape, it can be used to make some of the more free jewelry making

Type, such as plant leaves, petals, vines and so on. The inner surface finishing softwax is also very simple, the extrusion can be hard materials in general use and otherrelative should, for example, you can use the top of spherical punch squeeze out.

The wax material dressing, whether hard or soft wax wax will need to pay attention tothe thickness of wax, wax casting limit is 0.3mm, so the following dressing can not be less than this value, jewelry has no special requirement to the thickness to maintainabove 0.5mm.

Three, the hollow wax material

Hollow is a method commonly used in jewelry processing, it refers to the jewelrycarved out various holes make jewelry before or on the wing, in carving technology of other known as openwork. Using this processing method can increase the jewelrydecorative effect, on the other hand, can reduce the first

Cost of production of decorative metal thereby reducing the usage of the wholejewelry. More hollow in the carving wax process, there are two methods which are often used, one is to use the saw as the main means of hollow, another is to use acrane with dental needle pierced.

Using the method of sawing hollowed out the operation is relatively simple, generally used for large area of the hollow. Method: after the draw contour lines in the hollowpart, use the tool to drill a hole in the wax material, and then remove the saw bow end of the blade wear in, then tighten the blade, the excess wax material along the marked line

Sawed off.

Use the crane with dental needle pierced the need for training base, in drawing goodmark line, using a rotating force pin penetrating wax, and then along the marked lineengraving engraved patterns, this method is suitable for small area hollow, for example with mouth base ring hollow and local

Decorative pattern, these places higher requirement on the operator stability. In addition to these two ways and some other methods, such as wax melted to form holesusing electric iron, can achieve the effect of hollow and can be used as a specialprocessing method. Soft wax hollow relatively

Easy operation, use the knife is sharp purpose.

Four, the fusion of wax material

The fusion of wax material can be divided into the wax supply, split, connection, otherfour kinds.

(a) wax supply

In the process of processing defects due to operational errors or wax material itself(wax material part empty) make jewelry model of partial deletion, this situation will need to fill the wax. Method is: switch on the electric iron power, change the hot waxpowder or broken the wax is melted into liquid attached to the soldering iron tip,

And then bonded to the missing parts to be added. The wax material after cooling, the use of file or other tool will spare part trimming smooth.

(two) split

Combination of wax material refers to the area of surface and surface greater joint. In the process, raw material size not wax or wax material fracture to hours requiredcharacteristics of wax material, can use two pieces of wax material pieced together,each two pieces of wax material were placed on file

Platform, a few points of electric soldering iron tip in the spliced position of uniform,make two pieces of wax material relatively stable bonded together, the opposite is truea few. Use the soldering iron head a little rough will bond contact edge wax, wax after cooling on the back of the symmetric position can also be fusion. Positive
