The processing technology of automotive parts mainly includes mechanical processing, heat treatment, surface treatment, etc. Mechanical processing is the foundation of automotive parts processing, including turning, milling, drilling, grinding and other processes. Heat treatment refers to the process of changing the internal structure of a component through heating, cooling, and other treatment methods, in order to give it a certain degree of hardness, strength, and wear resistance. Surface treatment refers to coating, plating, spraying and other treatments on the surface of components to improve their corrosion resistance, wear resistance and aesthetics.

What are the key technologies for processing automotive parts in Dalian?

Numerical control machining technology: Numerical control machining technology is one of the common machining methods in modern automotive parts processing. Through CNC machine tools, high-precision machining of various complex shaped components can be achieved, improving production efficiency and product quality.

Metal cutting technology: Metal cutting is one of the basic machining methods in automotive parts processing. Cutting processing removes metal material from the workpiece through relative motion between the workpiece and the cutting tool, resulting in the desired shape and surface roughness of the workpiece.

Laser cutting technology: Laser cutting technology is a high-precision component processing technology. Laser cutting has the characteristics of non-contact processing, precise control, and high processing efficiency, and is suitable for processing thin plate components.

Welding technology: In the processing of automotive parts, many components require welding. Welding technology includes various methods such as arc welding, laser welding, plasma welding, etc., which can achieve the connection and repair of different materials.

Surface treatment technology: After processing, automotive parts often require surface treatment, such as spraying, coating, heat treatment, etc. Surface treatment technology can improve the corrosion resistance, wear resistance, and aesthetics of components.

Precision machining technology: Some automotive components require precision machining to meet the requirements for dimensional accuracy and surface quality. Precision machining technology includes optical machining, ultra precision machining, etc., which can achieve the machining of small-sized components.

Mold design and manufacturing technology: In the processing of automotive parts, many components need to be manufactured through molds. Mold design and manufacturing technology are key to achieving mass production of components. By optimizing mold structure and processing technology, the production efficiency and quality of components can be improved.

3D printing technology: In recent years, 3D printing technology has been widely applied in the field of automotive parts processing. 3D printing technology can achieve rapid manufacturing of complex shaped components, effectively shorten product development cycles, and reduce production costs.

Automotive parts processing refers to the process of processing various automotive parts during the production of automobiles. Automotive components are one of the constituent parts of a car, playing a crucial role in its normal operation and performance. Automotive parts processing is an indispensable part of the entire automotive production process, which directly affects the quality and performance of the car.

The commonly used machine tools for automotive parts processing include lathes, milling machines, drilling machines, boring machines, grinding machines, etc. Lathes are used for machining rotary parts, such as automotive shaft components. Numerical control lathes can precisely control tool paths through programming to achieve machining of complex shapes. For example, when the crankshaft of a car engine is machined on a lathe, the journal and balance weight of the crankshaft can be accurately machined through a multi axis linkage CNC lathe.
