In addition to the die-cutting mold which are made of ordinary carbon steel except for the tool; stereotypes and plastic molds are generally made of brass, aluminum and stainless steel. Forming dies are currently made of brass, aluminum alloy and resin. Used in the packaging industry, the accuracy is not high when the casting method can be used directly, the high precision must be machined by mechanical cutting. The transfer mold in the forming mold is best made by using the resin to be overturned from the corresponding punch or die, with high precision. If there is a paper sample, a low melting point alloy can be used as the master to directly overturn the die.
Mesh mold pulp mold is the key mold is a direct impact on product quality and production efficiency an important part. Mesh network with a metal mesh and plastic mesh, metal mesh is sub-brass network, stainless steel mesh and chrome mesh, mesh wire diameter between 0.15-0.25mm. According to the net weaving method is divided into single-net, triple-net, twist netting and double net weaving. Mesh geometry square holes, rectangular holes and hexagonal holes. The mesh is generally between 40-65 mesh.
Mold transitional material. The transitional material is used to make early prototypes or to over-mold the mold. Transition materials are wood, sand, paraffin, silicone rubber, plaster, resin and so on.
