Metal molds are used in industrial production, using various presses and special tools installed on the presses to make metal materials to produce parts or products of the required shape through pressure. Such special tools are collectively called hardware molds.
Plastic mold is a combined plastic mold used for compression molding, extrusion molding, injection molding, blow molding and low foam molding. It mainly includes a concave mold combined substrate, a concave mold assembly and a concave mold combined card board. The concave mold of the variable cavity is a convex mold with a variable core composed of a convex mold combination substrate, a convex mold component, a convex mold combination pallet, a cavity cutting component and a side cutting combination plate. Coordinated change of mold convex, concave mold and auxiliary forming system. It can process a series of plastic parts of different shapes and sizes.
The composition of plastic The plastic we usually use is not a pure substance, it is made up of many materials. Among them, polymer (or synthetic resin) is the main component of plastic
