Parts and materials
We manufacture and sell pins & bushes, essential parts of construction equipment and industrial facilities by serving as a bearing for low speed and high loads. Our materials, surface treatment, heat treatment, and cutting-edge processing technologies for pins & bushes and also application technologies improve durability and functions of industrial equipment and facilities.
Bush Materials
Bushes, which serve as bearings in low-speed, high-load environments, require high strength, wear resistance, and heat resistance. Common materials include :
- Carbon Steel : Cost-effective and easy to process, widely used in industrial machinery. Heat treatment enhances its hardness and strength.
- Alloy Steel : Enhanced with chromium, nickel, and other alloying elements for improved strength, wear resistance, and heat resistance, making it suitable for high-load, high-temperature applications.
- Stainless Steel : Offers excellent corrosion and heat resistance, ideal for humid or high-temperature environments.
- Bronze : Provides excellent wear resistance and self-lubrication, making it suitable for low-speed, low-load applications.
- Beryllium Copper : High strength, wear resistance, and heat resistance, used in high-performance components.
- Ceramic : Exceptional wear and heat resistance, ideal for extreme operating conditions.
Surface Treatment
Surface treatment enhances the wear resistance, corrosion resistance, and lubrication of bushes.
- Hardening : Increases surface hardness to improve wear resistance.
- Plating : Nickel, chromium, or zinc plating enhances corrosion resistance, wear resistance, and lubrication.
- Nitriding : Forms a hardened nitride layer on the surface, improving hardness, wear resistance, and heat resistance.
- Lining : Attaches wear-resistant materials to the bush surface for enhanced durability.
Heat Treatment & Advanced Processing Technologies
Heat treatment modifies the microstructure of bushes to improve strength, hardness, and toughness, while advanced processing techniques enhance precision and surface quality.
- Heat Treatment : Various methods such as carburizing, quenching, and induction hardening optimize the properties of bushes.
- Advanced Processing Technologies : CNC machining and EDM processing enable the precise manufacturing of complex bush shapes.
