What's the difference between casting mould and plastic mold?
The two is a different concept, refers to the casting mold manufacturing, including casting, cooling, grinding, forging; plastic mould is one of the types of plastic molding, blow molding and (you use plastic bags), extrusion molding (plate, bar). Die casting refers to the shape obtained in advance with other parts, easy molding materials into parts of the structure and shape, and then into the mold in the sand, then the sand has been formed in the cavity and a part of the same size and structure, in the cavity of the pouring flow of liquid, the liquid cooling and solidification can the shape of mold structure and identical parts. Casting mold is to obtain qualified parts of the model, ordinary hand molding, commonly used wood model, plastic model, mechanical modeling, multi-purpose metal model, such as: aluminum model, iron model.
Plastic mold production temperature of about 200 degrees, plastic mold wear little, general 500 thousand die also see wear. When the casting mould is produced, the temperature is above 600 degrees, the metal wears more seriously to the mold, and the 100 thousand mold has obvious wear and tear.The way of feeding is different from the principle, and the two are very large.The others are pretty much the same
Wax model for precision casting -- polystyrene model for expendable pattern. Die casting refers to the shape obtained in advance with other parts, easy molding materials into parts of the structure and shape, and then into the mold in the sand, then the sand has been formed in the cavity and a part of the same size and structure, in the cavity of the pouring flow of liquid, the liquid cooling and solidification can the shape of mold structure and identical parts. Casting mold is driven through the hydraulic cylinder pressure head, the metal liquid into the mold cavity at high speed, due to the use of oil pressure, high pressure, it is commonly known as casting mold process. Plastic mold is the plastic processing industry and plastic molding machine matching, giving plastic products to complete configuration and precise size tools. Because of the plastic varieties and processing methods of various plastic molding machine and plastic product structure is simplified, so the plastic mold of the type and structure is various. According to the different molding methods, can be divided into plastic mold types corresponding to different process requirements, the main injection molding extrusion mold, plastic mold, high foampolystyrene mold etc..
