Hardware mold, plastic mold and its special mold. Hardware dies are divided into: punching dies (such as punching dies, bending dies, stretching dies, hole-turning dies, shrinking dies, wavy dies, bulging dies, shaping dies, etc.). ), forging die (such as forging die, upsetting die, etc. ), extrusion die, extrusion die, die casting die, forging die, etc. Non-metallic molds are divided into plastic molds and inorganic non-metallic molds. According to the different materials of the mold itself, the mold can be divided into sand mold, metal mold, vacuum mold, paraffin mold and so on. Among them, with the rapid development of polymer plastics, plastic molds are closely related to people's lives. Generally, plastic molds can be divided into injection molds, extrusion molds and gas-assisted molding molds. In addition to the mold itself, the mold also needs the mold base, the mold base, and the device for ejecting the parts caused by the mold core. These parts are generally made into universal models. Mold enterprises need to be bigger and better, and determine product position control and market position control according to market demand, technology, capital and equipment. These practices are especially worth learning and learning from small mold enterprises, and concentrate on gradually forming their own technical advantages and product advantages. Therefore, mold enterprises in China must actively learn from the experience of these foreign advanced enterprises in order to develop better in the future. p？ There are many types of VC molds, and different types of PVC molds have different molding methods for plastic products. The molding methods here include press molding, injection molding, extrusion molding, blow molding and vacuum molding. Different molding methods of PVC are suitable for producing plastic products with different shapes and properties. For example, the components of electronic products such as televisions and computers are generally injection molded.
