What is a mold
Nov 20, 2017

Mold (mújù), industrial production for injection molding, blow molding, extrusion, die-casting or forging molding, smelting, stamping and other methods to obtain the required products of various molds and tools. In short, molds are tools used to make molded items, which are made up of various parts, and different molds are made up of different parts. It is mainly through the physical state of the formation of material changes to achieve the processing of goods shape. Known as "the mother of Industry" title.

A tool for making blanks into workpieces with specific shapes and sizes under external forces. Widely used in blanking, die forging, heading, extrusion, powder metallurgy parts repression, pressure casting, as well as engineering plastics, rubber, ceramics and other products, plastic or plastic injection molding process. The mould has a specific contour or an inner cavity shape, and a contour shape with a cutting edge can be used to separate the billet from the Contour shape (blanking). The internal cavity shape can be used to obtain the corresponding stereo shape. The mould generally includes two parts of the movable and fixed die (or Punch and die), the two can be divided. Remove the workpiece separately, and then the billet is injected into the mold cavity for forming. Mold is a precision tool, complex shape, bearing the strength of the billet, on the structure of intensity, stiffness, surface hardness, surface roughness and processing accuracy has a high demand, mold production level of development is an important symbol of mechanical manufacturing level.
