These are typically hollow cylindrical structures. Traditionally made of gray cast iron or ductile iron, they have undergone significant material upgrades through aluminum die-casting technology, which optimizes formulations using silicon-aluminum alloys, aluminum matrix composites, and other materials. These are rigidly connected to wheel hubs via flanges and rotate synchronously with tires. During braking, the excellent thermal conductivity of aluminum rapidly dissipates frictional heat, effectively alleviating the "thermal fade" issue of traditional cast iron components.
In terms of process characteristics, aluminum die-casting enables the integrated molding of complex brake drum structures with dimensional accuracy of ±0.1mm. Production efficiency is improved by over 40% compared to cast iron casting, making it highly suitable for mass production needs of original equipment manufacturers. In this process, aluminum die-cast products need to balance lightweight properties and impact resistance through alloy composition adjustments and heat treatment optimization. Their material formulations and die-casting process levels directly determine braking safety and market competitiveness.
Application Scenarios
Commercial vehicles
It places very specific requirements on the reliability, durability and lightweighting of these.
Urban logistics light trucks
It has a strong demand for the heat dissipation performance, lightweight design, and ease of maintenance of the braking system.
electric construction machinery
Its requirements for the impact resistance, sealing performance and corrosion resistance of these are much higher than those of ordinary vehicles.
Market Size and Growth Logic
Rising penetration of new energy commercial vehicles: Domestic new energy commercial vehicle sales will exceed 1.2 million units in 2025. Based on 2-4 brake drums per vehicle, the annual new demand for aluminum die-casting will exceed 3 million units.

our certifications
ISO 14001:2015
The ISO 14001:2015 certificate is an internationally recognized document that indicates that an organization has established, implemented, maintained, and continuously improved an environmental management system (EMS) that complies with the requirements of ISO 14001:2015.
This certificate certifies that the environmental management system of this organization has met international standards, enabling it to systematically manage its environmental responsibilities and commit to sustainable development.
IATF16949:2016
IATF 16949:2016 is an international standard for quality management systems in the automotive industry. It was developed by the International Automotive Task Force (IATF) and was released in October 2016, replacing the previous version of ISO/TS 16949:2009.
The core objective of IATF 16949 is to continuously improve, prevent defects, reduce variations and waste in the automotive supply chain. It aims to ensure that the design and manufacturing of automotive products (including components and materials) can always meet customer requirements and even exceed customer expectations.
