Automotive component manufacturing demands exceptional dimensional accuracy, strength, wear resistance, and consistency. Whether for engines, chassis, or electric drive systems in new energy vehicles, every part must maintain stable performance under high-temperature, high-load, and high-vibration conditions.

Leveraging over 30 years of precision manufacturing expertise, Keywin delivers integrated manufacturing solutions for both traditional fuel vehicles and new energy vehicles—from prototype samples to mass production delivery. Our capabilities encompass CNC machining, forging, casting, and diverse surface treatment processes, ensuring the reliability and precision performance of every product.

Keywin provides automotive CNC machining services and custom manufacturing solutions for automotive component manufacturers, OEM suppliers, and engineering companies. Our capabilities include high precision CNC milling, CNC turning, 5-axis machining, casting, forging, and sheet metal fabrication for custom metal and engineering plastic components.

From prototype development and design validation to small-batch manufacturing and repeat production, we help customers manufacture automotive-related components according to engineering drawings, material specifications, dimensional tolerances, and functional requirements.

By combining precision machining with complementary manufacturing processes, Keywin supports projects that require complex geometries, accurate mounting interfaces, consistent dimensions, and coordinated production.

Our Automotive Manufacturing Capabilities

CNC Machining for Automotive Components

Our automotive CNC machining support custom automotive components requiring accurate dimensions, controlled surface finishes, and repeatable machining quality.

Available processes include CNC milling, CNC turning, multi-axis machining, CNC drilling, grinding, and wire EDM for suitable geometries.

Typical automotive CNC machining applications include:

• Precision mounting brackets and connecting seats

• Aluminum housings and equipment covers

• Shafts, bushings, pins, and sleeves

• Mechanical connectors and fastening components

• Sensor mounting brackets and structural supports

• Custom automotive equipment components

Our engineers review critical dimensions, hole positions, thread specifications, surface roughness, and assembly interfaces before production.

CNC Milling for Complex Automotive Parts

Our CNC milling services support components with complex profiles, pockets, slots, mounting holes, and multi-face machining requirements.

Three-axis, four-axis, and five-axis machining can be considered according to component geometry and the required number of machining setups.

Typical applications include aluminum housings, mounting plates, structural brackets, and precision mechanical components.

CNC Turning for Rotational Components

Our CNC turning services support the manufacture of cylindrical and rotational automotive-related parts.

Typical components include shafts, pins, sleeves, bushings, spacers, and threaded connectors.

CNC turning is suitable for components requiring controlled diameters, concentricity, surface finish, and repeatable dimensional relationships.

Casting and Forging for Automotive Components

For components requiring more specialized forming processes, Keywin provides custom metal casting services and forging services.

Casting can be suitable for complex geometries and housings, while forging can be considered for components where mechanical strength and material deformation characteristics are important.

Post-process CNC machining can be incorporated to achieve the required dimensions on critical holes, threads, mounting faces, and mating surfaces.

Sheet Metal Fabrication for Automotive Equipment

Our sheet metal fabrication services support custom brackets, mounting panels, protective covers, equipment housings, and fabricated metal assemblies.

The process can include laser cutting, CNC bending, welding, and surface finishing, depending on the component design.

These capabilities are suitable for automotive production equipment, assembly fixtures, and selected vehicle-related metal components.
