Core Advantages

1. Superior Manufacturing Process, Reliable Quality

• Premium Materials: Made from high-strength cast iron (HT250/HT300) and alloy materials, offering excellent wear resistance, high-temperature tolerance, and crack resistance for extended service life.

• Precision Casting: Utilizes lost foam casting or resin sand casting processes to ensure dense internal structure, free from defects like sand holes or porosity, resulting in higher strength.

• CNC Machining: Precision-turned by CNC machines to guarantee roundness, balance, and smooth friction surfaces, ensuring stable braking with reduced vibration and noise.

• Rigorous Quality Control: Each product undergoes ultrasonic testing, dynamic balancing, and hardness inspection to comply with national standards (GB/T 9439) and industry requirements.

2. Customizable Solutions for Diverse Needs

• Supports customization of specifications (diameter, width, mounting holes), material grades, and surface treatments (e.g., anti-rust coating, quenching).

• Compatible with major domestic and international vehicle brands (e.g., Fuwa, BPW, JOST) and offers OEM/ODM services.

3. High Cost Performance, Worry-Free After-Sales
