Materials Science & Surface Treatment Expertise
High-Strength Fasteners
Fasteners for automotive and motorcycles, made from high-strength alloy steels, Grade 10.9, Tensile Strength 1130 MPa. Surfaces can undergo various wear and corrosion-resistant treatments like phosphating or blackening.
High-Hardness Bushings
Bushings for railway applications, made from special high-strength alloy steels or stainless steels. The inner surface achieves a hardness of 500+100 HV10 with a hardened layer depth of 0.8+0.4mm, providing notable high hardness and wear resistance.
These components form the physical foundation for the long-term, stable operation of equipment. We specialize in manufacturing critical base parts essential for overall system reliability, such as high-hardness wear-resistant bushings and high-strength specialized fasteners. Through deep material science expertise and surface engineering technologies, we ensure each component maintains its performance and integrity under demanding conditions—including heavy loads, constant friction, and corrosive environments. Our value lies in elevating these seemingly “standard” parts to a reliability grade that matches the service life of the host machinery, thereby helping customers reduce downtime, lower maintenance costs, and enhance the market reputation of their end products.

We have a six-axis robotic production line for the production of transmission pneumatic control valves, and the daily capacity can reach 1,200 sets.
The company has more than 50 employees, including more than ten professional technicians and engineers.
The company has established an ISO9001 quality management system and passed iatf16949 certification. From product development, the sample manufacturing to mass production, each step is carried out according to the quality control plan and process flow. FMEA and SPC are necessary to control methods. Laboratory testing equipment includes CMM, hardness testers, metallographic testers, roughness testers, film thickness testers, image projectors, leakage testers, etc. During the production process, perform the first article inspection, process sampling inspection, and final inspection of final products. The above systems and processes ensure that the product quality meets the requirements.
When we quote for you, we will confirm the method of order transaction, FOB, CIF, CNF, etc. For mass production goods, you need to pay a 30% deposit before producing and a 70% balance against a copy of documents. The most common way is by T/T. L/C is also acceptable.
