(Summary description)Surface treatment: although rapid prototyping technology has not been available for a long time, it has been widely used because of its great benefits to the manufacturing industry, especially for the design and manufacturing of molds.
Zinc aluminum die-casting mold technology is mostly based on the solid model made by rapid prototyping, that is, the sample mold (mother mold) adopts the copy method (such as metal spraying, electroplating, composite material pouring, precision casting, etc.) to rapidly manufacture the main working parts of the mold (convex, concave mold or mold cavity, mold core). Its manufacturing cycle is generally 1/5 ~ 1/10 of the traditional NC cutting method, but the cost is only 1/3 ~ 1/5.
A variety of process methods have been developed according to the requirements of zinc aluminum die casting die, production cost, RP prototype material, production batch and die precision. At present, there are two kinds of rapid tooling methods: indirect tooling and direct tooling. Most of the RP based rapid tooling methods are indirect tooling. According to different materials, the molds produced by indirect molding method include soft mold, bridge mold and hard mold. Softtooling usually refers to silicone rubber mold. The prototype made by SLA, FDM, LOM or SLS technology is turned into a zinc aluminum die-casting mold, and then two-component polyurethane is poured into the mold. After curing, the required parts are obtained.
