Mission And Vision

Materials for automotive product manufacturing

The development of automotive products requires the use of various materials, including steel, aluminum alloy, carbon fiber, plastic, and rubber. Choosing appropriate materials can help cars improve energy efficiency, safety, and performance.


Steel is one of the most commonly used materials in automobile manufacturing because it has advantages such as high strength, corrosion resistance, and plasticity. Automotive chassis, body, and engine components are commonly made of steel.


Aluminum alloy is a lightweight, high-strength, and corrosion-resistant material suitable for manufacturing automotive body, wheel hub, and engine parts. Aluminum alloys have good thermal conductivity and conductivity, which can help improve energy efficiency in automobiles.

carbon fibre

Carbon fiber is a lightweight, high-strength, and high stiffness material suitable for manufacturing components such as car bodies and chassis. Carbon fiber has excellent wear resistance, corrosion resistance, and damping properties, which can improve the safety and performance of automobiles.


Plastic is a lightweight, easy to process, and low-cost material suitable for manufacturing automotive interior, lights, doors, and other components. Plastics have excellent wear resistance, corrosion resistance, and insulation properties


Rubber is an elastic material suitable for manufacturing components such as tires, seals, and shock absorbers in automobiles. Rubber has excellent wear resistance, corrosion resistance and aging resistance.
