Automotive Parts We Provide
Machining parts
Cylinder Head
Combining casting (complex inner cavity molding) and CNC machining (precision airway and mounting surface machining), emphasizing material adaptability (such as lightweight aluminum alloy) and surface finish control (Ra ≤ 0.8μm)
The cylinder head is an important part of the engine. It is located above the cylinder block, enclosing the cylinder chamber and accommodating valves, spark plugs and other components. It is responsible for managing airflow through the connection of the valves and the intake and exhaust systems to ensure the smooth operation of the engine.
Machining parts
Water Pump housing
Die-casting technology achieves thin-wall structure (≤3mm), CNC machining of flow channels and flange surfaces to reduce fluid resistance
The water pump housing is part of the water pump system and is responsible for housing the water pump components and ensuring the proper operation of the water pump. It is a key component in the car’s cooling system, helping to circulate coolant to various parts of the engine.
Suspension parts
Gas Spring
Forged piston rod (high-strength steel) + CNC drilling (air pressure adjustment hole), outstanding tensile strength ≥ 1000MPa and anti-corrosion coating
Gas springs are commonly used in car seats, trunks, doors, and other parts to provide support, cushioning, and adjustment functions. It stores energy by compressing gas and releases it when needed to provide smooth lifting and support.
Suspension parts
Control Arm Bushing Parts
Casting shell (aluminum alloy) + CNC machined inner hole, combined with rubber/polyurethane composite process, meets NVH performance standards.
Control arm bushings are used in suspension systems to connect the control arm to the vehicle body, playing the role of shock absorption and road shock absorption. It helps the vehicle maintain a smooth ride and provides better handling performance.
Engine parts
Camshaft
Cold forging process improves grain streamline strength, CNC finishing ensures contour accuracy of ±0.02mm, suitable for high-performance engines
The camshaft controls the opening and closing timing of the valves in the engine, affecting the engine’s efficiency, power output and emission control. It is a core component in the engine and directly affects the engine’s performance.
Water Pump
Pump Cover
Cold forged stainless steel cover + CNC sealing surface processing, flatness accuracy ≤ 0.03mm, eliminating the risk of leakage.
The water pump cover is the closed part of the water pump system, protecting the internal mechanical components while helping the water pump maintain proper pressure and seal when working. It is often used in the engine’s cooling system to ensure the normal flow of coolant.
