Train Brake Shoe Mold | Precision Manufacturing for Railway Brake Components
A cornerstone of railway brake system production, the train brake shoe mold is a specialized tool engineered to precision-form brake pads and shoes-critical components that ensure safe, reliable braking in locomotives, freight wagons, and passenger trains. Designed to withstand the demands of high-temperature, high-pressure molding processes, this train brake shoe mold transforms raw materials (including composite resins, heat-resistant alloys, or specialized friction-reducing compounds) into durable, dimensionally accurate brake parts that meet strict industry safety standards.
Key Features & Benefits:
* Precision Engineering:
Equipped with carefully machined cavities and reinforced structures, the mold minimizes material waste, reduces defect rates (e.g., air pockets or uneven density), and ensures uniform hardness across brake pads, directly enhancing their wear resistance and braking consistency.
* High-Temp/High-Pressure Performance:
Optimized for industrial-scale molding, it maintains structural integrity under extreme conditions, guaranteeing consistent part quality even for large or complex brake shoe designs.
* Industry Compliance:
Manufactured to align with international railway standards, it supports both OEM production of new brake components and aftermarket replacement part manufacturing, critical for global rail operators and maintenance providers.
By combining robust construction with efficient molding capabilities, it helps leading railway equipment manufacturers can boost production throughput while delivering parts that prioritize safety, durability, and performance.
Working principle
First, the raw materials for the brake shoe (such as synthetic compounds or powder metallurgy materials) are placed into the cavity of the lower mould. The upper mould is then driven downward by the press to close the mould. As the mould closes, the heating device activates, raising the mould to the specified temperature. Under high temperature and pressure, the material is compacted and fills the cavity, gradually forming the shape of the brake shoe.
After a set period of pressing and heat preservation, the heating device is turned off, and the cooling system begins to cool and solidify the brake shoe. Finally, the press lifts the upper mould, and the demoulding mechanism ejects the finished brake shoe from the mould, completing one production cycle.
Products Features
* Train brake shoe moulds are available in single-cavity, double-cavity, and multi-cavity designs, and can be customised according to customer requirements.
* The mould supports continuous hot pressing (customised based on customer equipment and needs), offering easy operation, high output, and convenient maintenance.
* Since hot-pressing moulds must withstand high temperatures and pressures, the mould base material requires high strength, hardness, heat resistance, and wear resistance. The mould core is made of forged 40Cr parts, with a heat-treated hardness of HRC42-55.
* High-quality die steel is embedded within the mould frame. After heat treatment, it achieves a hardness of HRC58-60 and offers excellent wear resistance, high temperature resistance, and extrusion resistance. These properties significantly extend the mould's service life and help maintain product precision.
* The positioning method of the train brake shoe mould depends on the product structure. Exhaust grooves are added around the core to enhance efficiency, prevent foaming during moulding, and reduce the scrap rate.
