OEM Custom CNC Turning Machining Auto Parts High Precision Aluminum Steel Flange

Introduction:
In the fast-evolving automotive industry, precision, durability, and reliability are non-negotiable. Our OEM Custom CNC Turning Machining Auto Parts are engineered to meet the highest standards, offering exceptional performance for critical applications. Specializing in high-precision aluminum and steel flanges, we deliver tailor-made solutions that align with your exact specifications, ensuring seamless integration into your automotive systems.

Manufacturing Excellence:
Our production process adheres to ISO 9001:2015 and IATF 16949 standards, encompassing:

1. Material Sourcing: Premium aluminum and steel billets from certified suppliers, verified through spectroscopic analysis for chemical composition.
2. CNC Machining: Multi-axis turning centers with live tooling capabilities, achieving complex geometries and surface finishes up to Ra 0.8μm.
3. Heat Treatment: Customized quenching and tempering processes to enhance material properties (e.g., HRC 38-42 for 4140 steel flanges).
4. Surface Finishing: Options include zinc plating (8-12μm thickness), powder coating, and black oxide treatment for corrosion protection.

Case Studies:
1. Electric Vehicle (EV) Drive Unit
Client: Leading EV Manufacturer
Challenge: Develop a lightweight yet robust flange for the motor-to-transmission interface.
Solution: Custom 6061-T6 aluminum flange with internal splines, reducing weight by 40% compared to steel alternatives while maintaining torque transmission capabilities.
Result: Improved power-to-weight ratio, extended battery range by 5%, and reduced NVH (Noise, Vibration, Harshness) levels.
2. Heavy-Duty Truck Suspension System
Client: Commercial Vehicle OEM
Challenge: Design a flange capable of withstanding 200,000+ cycles of dynamic loading without fatigue failure.
Solution: Forged 4140 steel flange with optimized fillet radii and shot peening treatment, increasing fatigue life by 250%.
Result: Reduced maintenance downtime by 30% and eliminated field failures in over 50,000 vehicles.

Applications:
Our flanges are integral to various automotive systems:

1. Powertrain: Transmission mounts, differential housings, and engine flywheel connections.
2. Suspension: Control arm bushings, shock absorber mounts, and steering knuckle assemblies.
3. Braking System: Caliper brackets, brake hose connectors, and ABS module mounts.
4. Exhaust System: Manifold flanges, catalytic converter mounts, and muffler connections.
