Moulds and tools used in industrial production to get the desired products by injection molding, blow molding, extrusion, die-casting or forging, smelting, stamping, etc.
In short, a mold is a tool used to make molded objects, which is made up of various parts, and different moulds are made up of different parts.

In short, a mold is a tool used to make molded objects, which is made up of various parts, and different moulds are made up of different parts.
It mainly realizes the processing of the shape of the object through the change of the physical state of the formed material.
Known as the "mother of industry" title.
A tool that makes a blank a product of a specific shape and size under the action of an external force.
It is widely used in blanking, die forging, cold heading, extrusion, powder metallurgy parts pressing, pressure casting, as well as pressing or injection molding of engineering plastics, rubber, ceramics and other products.
The die has a specific profile or inner cavity shape, and the application of the profile shape with a cutting edge can make the billet separate (blanking) according to the contour shape.
The corresponding three-dimensional shape of the billet can be obtained by using the internal cavity shape.
The mold generally includes two parts: the dynamic die and the fixed die (or punch and concave die), which can be separated and combined.
When the parts are separated, the parts are taken out, and when they are closed, the billets are injected into the mold cavity to form.
The mold is a precision tool with complex shape, bearing the expansion force of the billet, and has high requirements for structural strength, stiffness, surface hardness, surface roughness and machining precision. The development level of mold production is one of the important symbols of the level of mechanical manufacturing.
There are many kinds of moulds.
According to the processing object and processing technology, it can be divided into:
1 the mold for processing metal.
(2) processing non-metallic and powder metallurgy moulds.
Including plastic moulds (such as two-color moulds, compression moulds and extrusion moulds, etc.), rubber moulds and powder metallurgy moulds, etc.
According to the structural characteristics, the die can be divided into plane blanking die and cavity die with space.
The mold is generally a single piece, small batch production.
