Automotive moulds are becoming more and more important in the mould industry. More than 1500 auto parts moulds are used to make a car, and the mould design is complicated, and many mould surfaces are two-dimensional or three-dimensional curves. Process requirements are high, and the error is generally controlled within 0.01mm. The technology is advanced. Some large auto part moulds, such as car body panel moulds, must be produced using advanced CNC machine tools. Only a few countries in the world master this technology. Let's talk about the classification of auto mould parts.

1. Auto mould parts can be divided into 4 categories according to the manufacturing process.

• Stamping and bending automotive moulds are bent according to the curve on the stamping material to form a certain angle and shape.
• Stamping and cutting automotive moulds, the moulds that are punched out according to the curve on the material.
• Deformation and deepening of automotive moulds, the stamping material is made into open hollow parts, or the deformation and deepening will continue to occur on the basis of the open hollow parts.
• Stamping and forming automotive moulds use concave and convex moulds as models, and the stamping materials are copied and formed by stamping.

2. According to the moulding method, it can be divided into

• Injection moulding
• Ceramic membrane forming
• Extrusion moulding
• Stamping mould forming
• moulding by vulcanization mould

3. according to the mould materials can be divided into

• Carbon steel automotive mould
• Carbide steel car mould
• Tool alloy steel automotive mould
• Bearing steel moulds and cast carbon steel, etc.
