China Trailer Brake Drum Factory

Trailer Brake Drum Manufacturers

Trailers encounter a wide range of braking demands, from light-duty landscape trailers to heavily laden equipment haulers. As specialized Trailer Brake Drum Manufacturers, Xingtai SNT Auto Parts Factory tailors its production to accommodate variable duty cycles and environmental conditions. Each trailer brake drum begins with a duty-analysis study, determining ideal wall thickness, cooling-fin depth, and material grade based on expected load and braking frequency.

Our foundry employs automated core-shooting and high-pressure molding to produce castings with consistent density and minimal porosity. Following casting, each drum passes through a sequence of rough machining and precision CNC turning operations. Critical features—such as mounting flange flatness, friction surface concentricity, and bolt-circle accuracy—are held within tight tolerances (±0.05 mm), ensuring direct fit with trailer hubs from a variety of axle configurations.

Quality control covers dimensional checks via coordinate measuring machines (CMM), dynamic balancing to eliminate vibration, and non-destructive inspections using magnetic particle and ultrasonic techniques. Rockwell hardness tests confirm the drum’s capacity to resist thermal fatigue, while salt-spray exposure trials validate corrosion-protection coatings for long service in moist or road-salt environments.

To support aftermarket needs, our engineers provide detailed resurfacing guidelines, specifying safe machining allowances and inspection intervals aligned with brake lining changes. Custom drum designs—for specific stud patterns, commercial paint finishes, or integrated wear-indication grooves—are available on request, enabling trailer builders and retrofit shops to maintain operational flexibility.

Through a combination of application-driven design, advanced casting and machining, and rigorous testing, Xingtai SNT Auto Parts Factory delivers trailer brake drums that meet the practical demands of towing applications while simplifying maintenance and extending component life.
