What Is a Prototype Mold?
Rapid tooling (RT, Rapid Tooling) is a tool that uses its specific shape to form products with a certain shape, size and surface accuracy. It is mainly used for mass production. Although the cost of mold production and manufacturing is relatively high, due to mass production, the cost of each product is greatly reduced.
Rapid tooling
- Traditional adoption
- Can be divided into functional uses
- Due to the high cost of silicone rubber materials, people have studied a process for making silicone rubber molds by mixing with gypsum.
- The idea of arc spray molding originated from Net-shapethermalsprayforming proposed in the 1960s,
- The arc spray molding technology has the following advantages: (1) Regardless of whether the material of the original mold is metal,
- The basic structure of the arc spraying mold: The basic structure of the arc spraying mold can be divided into three parts, namely the metal spraying layer, the backing layer and the steel structure part. For the zinc alloy mold, the spray coating layer of the mold is composed of zinc alloy droplets. When spraying, the zinc alloy wire is heated and melted to form metal droplets by compressed gas atomization. The droplets are sprayed against the surface of the transition mold and solidified. A hard and dense metal shell layer forms the surface layer of the mold cavity, and its thickness is generally 2 to 3 mm. Although the spray coating has a certain strength, hardness,
- The rapid molding of epoxy resin borrows a metal pouring method, and the prepared pouring material (the resin is uniformly mixed with additives) is injected into a certain cavity to be cured (polymerization or polycondensation reaction is completed), thereby obtaining a mold method. Epoxy resin rapid molding is generally used at room temperature and pressure.
