Automobile manufacturing process:

1. Casting

Casting is a production method in which molten metal is poured into a mold cavity, cooled and solidified to obtain a product. In the automobile manufacturing process, there are many parts made of cast iron blanks, accounting for about 10% of the total vehicle weight, such as cylinder blocks, transmission cases, steering gear housings, rear axle housings, brake drums, various brackets, etc. . Sand molds are usually used to manufacture cast iron parts.

2. forging

In the automobile manufacturing process, forging processing methods are widely used. Forging is divided into free forging and model forging. Free forging is a processing method in which a metal blank is placed on an anvil and subjected to impact or pressure to form it.

3. cold stamping

Cold stamping or sheet metal stamping is a processing method in which sheet metal is cut or formed under pressure in a die. Daily necessities, such as women's aluminum pots, lunch boxes, washbasins, etc. are made using cold stamping processing methods.

4.Welding

Welding is a processing method in which two pieces of metal are joined together by local heating or simultaneous heating and pressure. The common welding method in which workers hold a mask in one hand and a welding clamp and welding rod connected to a wire in the other hand is called manual arc welding. This method uses the high temperature generated by arc discharge to melt the welding rod and weldment to join them.

5. Metal cutting processing

Metal cutting is a processing method that uses tools to cut metal blanks layer by layer to obtain the required shape, size and surface roughness of the workpiece.

6. heat treatment

Heat treatment is a method of reheating, maintaining or cooling solid steel to change its organizational structure to meet the use requirements or process requirements of parts. The heating temperature, the length of holding time, and the speed of cooling can cause different structural changes in steel.

7． assembly.

Assembly is to use connecting parts (bolts, nuts, pins or buckles, etc.) to connect and combine various parts into components according to certain requirements, and then connect and combine various components to each other to form a complete vehicle.
