Aluminum Alloy Automotive Parts CNC Precision Machining - Professional Customization, High Precision, Lightweight Solution 

ISO 9001:2016 certified factory | Three axis/Four axis/Five axis CNC machining center | Own anodizing production line

Product Overview 

In the wave of automotive lightweighting and new energy revolution, aluminum alloy is irreversibly replacing traditional steel as the preferred material for body, chassis, and core components. Aluminum alloy has a density only one-third that of steel, while also possessing excellent strength to weight ratio, thermal conductivity, and corrosion resistance, making it an ideal lightweight material for automobiles.

We specialize in providing CNC precision machining services for aluminum alloy automotive parts, offering one-stop delivery from prototype sampling to mass production. The products cover a wide range of engine components, suspension systems, chassis parts, new energy three electric system housings, etc., which can meet diverse needs such as original factory matching, racing performance upgrades, and new energy vehicle lightweighting. With advanced multi axis CNC machining center clusters, mature process technology, and strict quality management systems, we are committed to providing high-precision, high consistency, and cost-effective customized processing solutions for aluminum alloy parts to global automotive industry customers.

Core advantages

High precision manufacturing, micrometer level control

We are equipped with multi axis CNC machining centers that can achieve micrometer level (μ m) precision machining of complex geometric shapes. The standard machining accuracy can reach ± 0.005mm to ± 0.01mm, ensuring that every hole, thread, and mating surface is precise and meets the stringent requirements of the automotive industry for component interchangeability and assembly consistency. For complex components such as electric drive shaped shells, a composite process route of 'three-axis CNC rough machining+five axis CNC precision machining' is adopted to ensure shape and position accuracy and surface quality.

Proficient in materials and precise selection of materials

Proficient in the processing characteristics of various automotive grade aluminum alloys, including but not limited to:

6061-T6: Excellent comprehensive performance, suitable for structural components, brackets, and shells 

7075-T651: High strength aviation grade aluminum alloy, suitable for racing components and suspension systems 

5083: Excellent corrosion resistance, suitable for marine environments and chassis components 

6082: Good extrusion formability, suitable for large structural components

We can accurately recommend and process the most suitable materials based on your performance requirements (strength, weight, thermal conductivity).

Integrated production, quality closed-loop 

The entire process from CNC machining to surface treatment is completed internally within the company, eliminating the possibility of scratches, bumps, contamination, and delivery delays caused by external circulation. Our own anodizing production line can provide various surface treatment solutions such as hard anodizing, sandblasting, powder coating, electroplating, etc. The surface hardness of the hard oxide film can reach HV500 or above, and its salt spray resistance can pass the neutral salt spray test for more than 500 hours. At the same time, the thickness of the oxide film (5-25 μ m) and color (black, natural color, blue, etc.) can be precisely controlled according to the needs.

Flexible manufacturing, fast response

Support a full range of orders from prototyping to mass production. Integrating multiple processes such as turning, milling, drilling, and tapping to reduce secondary processing and shorten delivery cycles. Samples can be completed within 7 days at the fastest, and bulk orders can be delivered within 7-15 working days.
