The accuracy of the mold includes the accuracy of the parts obtained during processing and the quality awareness of ensuring the accuracy of the product during production, but the mold accuracy we usually talk about mainly refers to the accuracy of the working parts of the mold.

Die forging is a method of forming on a forging die developed on the basis of free forging and die forging in order to solve the problems of low productivity and poor precision of free forging, and to achieve the needs of large-scale and specialized production of forgings. Die forging is the abbreviation of model forging. The forging die (forging die) is generally composed of an upper die and a lower die. The upper and lower dies of the forging die are respectively fixed on the hammer head and the die pad. or die groove), the shape and size of the cavity of the groove is the same as the shape and size of the forging. During die forging, the blank is placed on the lower die, and the upper die moves down with the hammer (or slider) to close the die (one or more times) to hit the blank. Under the action, plastic deformation is generated and the groove is filled, and finally a forging with the same shape as the groove is obtained.

Powder metallurgy is a process technology for preparing a mixture of metal powder and non-metal powder as a raw material, after forming and sintering, to manufacture metal materials, composite materials and various types of products. Powder metallurgy products industry only refers to powder metallurgy products, including powder metallurgy parts, oil-impregnated bearings and metal injection molding products. Today we will take a closer look at this process.

Machining aluminum requires tools with certain special properties. Ideally, the cutting tools used for such materials allow for efficient removal of the material to avoid possible damage to the part and passivation of the cutting tool, also, the rake angle should be larger than that used for machining steel. Due to the high thermal conductivity of aluminum, the cooling process of the cutting tool does not require as much coolant flow as is sufficient to expel the separated material.

CNC (computer numerical control), also called Numerical control. It refers to the automatic control of machining tools and 3D printers through computers.

The die-casting process is a process of organically combining and using the three die-casting production elements of die-casting alloy, die-casting mold and die-casting machine. There are many factors that affect the filling and forming of molten metal during the pressure prayer, among which the injection force, injection speed, filling time and die temperature are the main ones.
