The hino brake drum 43512-1023 is a critical component engineered to meet the braking requirements of medium-duty commercial trucks. At Xingtai SNT Auto Parts Factory, our production of this model centers on precision, material integrity, and consistent dimensional accuracy to ensure each drum performs reliably across a variety of operating conditions.
Brake drum 43512-1023 is cast from a proprietary grey cast iron alloy selected for its combination of wear resistance and thermal conductivity. The material undergoes strict chemical analysis to verify carbon and silicon content, assuring optimal hardness after heat treatment. The drum’s external geometry features a uniform wall thickness and internal cooling fins designed to promote airflow and accelerate heat dissipation during repeated braking events.
Our manufacturing workflow begins with advanced mold making, using computer-aided design files to produce sand molds that hold the molten metal precisely. After controlled cooling, each casting is removed and undergoes a rough-machining pass to establish the inner bore and mounting flange. Subsequent CNC operations refine critical dimensions—such as friction surface concentricity (held within ±0.05 mm), bolt circle accuracy, and drum depth—to exact tolerances. Final finish grinding imparts a smooth braking surface that promotes uniform pad contact and predictable friction behavior.
Post-machining, drums receive a stress-relief heat treatment to reduce residual casting stresses and increase fatigue life. A batch of finished drums is sampled for Rockwell hardness testing, ensuring values fall within the specified range for this model. Non-destructive testing—magnetic particle inspection—identifies any surface-breaking discontinuities. Dynamically balanced units are marked with a balance score, certifying vibration-free operation once installed.
The 43512-1023 drum is designed for axles with flange patterns matching Hino medium-duty series. Maintenance crews benefit from the drum’s uniform wall section, which wears evenly and allows for safe re-machining up to the minimum service diameter. Recommended inspection intervals coincide with brake lining replacement, and our technical documentation provides clear guidelines for measuring run-out and bore tolerances during each service.
Xingtai SNT Auto Parts Factory maintains a consistent inventory of 43512-1023 drums, enabling rapid order fulfillment for individual garages and fleet operators alike. Each shipment includes detailed installation instructions and service-life projections, supporting maintenance planning and minimizing vehicle downtime.
