Detailed introduction

Molds (mj) are used in industrial production to obtain all kinds of moulds and tools needed for products by injection, blow moulding, extrusion, die casting or forging, smelting and stamping.

In short, the mould is a tool used to make moulding objects. This tool is composed of various parts, and different moulds are composed of different parts. It mainly realizes the processing of the shape of the object by changing the physical state of the forming material. It is known as the "mother of industry".

Under the action of external force, the billet becomes a tool for manufacturing with specific shape and size. It is widely used in stamping, die forging, cold heading, extrusion, powder metallurgy parts pressing, pressure casting, as well as engineering plastics, rubber, ceramics and other products of compression or injection molding. The die has a specific contour or inner cavity shape, and the blank can be separated according to the contour shape (blanking) by applying the contour shape with the edge. The shape of the inner cavity can be used to obtain the corresponding three-dimensional shape of the billet.

Mould generally includes two parts: movable die and fixed die (or punch and concave die), which can be separated and combined. When the parts are separated, the blanks are injected into the die cavity to form when they are closed. Mould is a precise tool with complex shape and bearing the expansion force of billet. It has high requirements on structural strength, rigidity, surface hardness, surface roughness and processing accuracy. The development level of mould manufacturer's production is one of the important symbols of mechanical manufacturing level.
