Our Factory
Technical Advantages
In the 13-year process from 2011 to 2024, we continued to optimize the production process and continue to improve product quality. We have professional equipment, including more than 80 high-precision equipment, which provide a solid hardware foundation for product production. At the same time, there is a strong team of 10 professional engineers to build a strong defense line and protect the technical level, ensuring that our products always maintain a leading edge at the technical level, and every link can withstand the test of the market and customers.
Factory Size
It covers an area of more than 8,000 square meters, has more than 110 sets of equipment, and more than 80 sets of professional equipment. The annual output value of pins and bushings is 36 million.
Quality Control Process
Since 2018, we have passed ISO9001 quality management system certification, which is an authoritative recognition of our quality management level. At the same time, we are equipped with a series of advanced quality inspection equipment, including Rockwell hardness testers, three-dimensional coordinate measuring machines, magnetic particle flaw detectors, metallographic testing equipment, etc. From the procurement of raw materials to the completion of finished products, every link must undergo comprehensive and 100% strict testing by quality inspectors, and no details that may affect quality will be missed to ensure that every product meets high standards. Quality quality standards to provide customers with high-quality, reliable products.
In order to meet the cost needs of many customers, we support high-frequency heat treatment on the surface of the pin shaft, and the depth of the hardened layer is 1mm-2.5mm. This heat treatment process is lower cost and meets the needs of the mid-range market.
Raw material conditioning treatment
The raw materials are quenched and tempered to increase the overall core hardness of the pin. After machining, the surface is subjected to intermediate frequency treatment. The hardening depth can reach 3mm-6mm. Finally, tempering treatment is performed to release the internal stress generated by the intermediate frequency and improve the quality of the pin. good.
Chrome plated surface
The surface of the pin is electroplated with hard chromium and is produced according to the thickness of the chromium plating required by the customer. The chromium-plated pin has extremely high hardness and has the advantages of anti-rust and anti-corrosion.
Surface galvanized
Electro-galvanizing is performed on the surface of the pin shaft. Colored zinc, blue zinc, blue and white zinc and other different styles can be electroplated according to customer requirements, which has excellent anti-corrosion and anti-rust effects.
About Bushings
Carburizing heat treatment
Our company's bushings all use carburizing heat treatment for heat treatment. The hardness is stable, the deformation is extremely small, and the depth can reach 0.8mm-1.5mm.
Manganese phosphating graphite spray coating
The entire bushing is treated with manganese phosphating, which has the advantages of anti-corrosion and anti-rust, and can reduce the friction coefficient between the bushing and the pin. Then a layer of graphite is sprayed on the phosphated inner diameter of the bushing, which greatly improves the lubricity and overall hardness.
Dyeing treatment
We can also surface-dye the bushings, most of which are pure black, but can also be dyed in brass, red, etc. according to customer requirements. In addition to appearance, it also has the function of preventing rust.We can also surface-dye the bushings, most of which are pure black, but can also be dyed in brass, red, etc. according to customer requirements.

Manganese based phosphating treatment
Manganese based phosphating surface treatment has the advantages of corrosion resistance, rust prevention, and reduced friction. Reduce frictional stress with the pin shaft during operation, thereby improving product durability.
