The more common approach is: first of all, according to the requirement of the productdesign (can leave allowance or not very small margin) mold, with the method of castingcasting wax, obtain the original wax; repeated coating and sanding processes in wax,hardened shell and drying; then the internal wax
Die melt, for dewaxing, obtaining cavity; roasting shell to obtain enough strength; metalmaterials pouring needed; after the shell sand cleaning, and obtain high accuracy of finished products. It can obtain the relative precision forging correctly shape and higher. Precision forging is compared with the traditional forging
Build a forging process in terms of. According to the requirement of the product or heat treatment and cold working.
