模具的分类
Classification of Dies
按所成型的材料的不同
Depending on the material being moulded
五金模具、塑胶模具、以及其特殊模具。
Hardware mold, plastic mold, and its special mold.
五金模具分为：包括冲压模 （ 如冲裁模具、弯曲模具、拉深模具、翻孔模具、缩孔模具、起伏模具、胀形模具、整形模具等）、锻模（如模锻模、镦锻模等）、挤压模具、挤出模具、压铸模具、锻造模具等；
Hardware dies are divided into: stamping dies (such as punching dies, bending dies, drawing dies, turning dies, shrinkage dies, undulating dies, bulging dies, shaping dies, etc.), forging dies (such as forging dies, upsetting dies), extrusion dies, extrusion dies, die casting dies, forging dies, etc.
非金属模具分为：塑料模具和无机非金属模具。而按照模具本身材料的不同，模具可分为：砂型模具，金属模具，真空模具，石蜡模纤维 驱鸟设备 保定通风管道 塑料土工格栅 检查井模具 流水槽模具 锻造厂家 华尔街铜牛具等等。其中，随着高分子塑料的快速发展，塑料模具与人们的生活密切相关。塑料模具一般可分为：注射成型模具，挤塑成型模具，气辅成型 模具等等。
Non-metallic dies are divided into plastic dies and inorganic non-metallic dies. According to the different materials of the mould itself, the mould can be divided into sand mould, metal mould, vacuum mould, paraffin mould and so on. With the rapid development of polymer plastics, plastic moulds are closely related to people's lives. Plastic moulds can be generally divided into: injection moulds, extrusion moulds, gas-assisted moulds and so on
