As of March 31, 2026, Huizhou Quanyi Precision Hardware Products Co., Ltd. has successfully delivered nearly 50,000 custom 316 stainless steel fasteners to customers in Europe and North America. These components are used as critical fastening elements in industrial equipment heat dissipation systems.
The delivered parts are machined from 316F stainless steel, offering strong corrosion resistance and mechanical stability. The outer diameter tolerance is controlled within ±0.02 mm, and the length tolerance within ±0.05 mm, meeting high-precision assembly requirements.
In terms of reliability, all products have passed a 200-hour neutral salt spray test with no signs of red rust. The surface is treated with environmentally friendly passivation and undergoes a deburring process to ensure safe assembly. All components comply with RoHS environmental standards.
Throughout the project, strict quality control was implemented across the entire production process-from raw material inspection and CNC precision turning to surface treatment-ensuring consistency and stability in mass production.
Currently, Our company has a monthly production capacity of several hundred thousand precision turned parts. The company can flexibly adjust dimensional tolerances, surface treatments, and packaging solutions based on customer requirements.
The company specializes in high-precision metal component manufacturing, working with materials such as stainless steel, brass, aluminum, and carbon steel. Its products are widely used in heat dissipation systems, automotive, electronics, and medical equipment industries, serving customers across Europe, North America, and Japan.
With a stable quality control system and extensive machining experience, our company supports both small-batch prototyping and large-scale production. Customers are welcome to contact us for CNC turning and other precision components.
