Henghui Precision Molds empowers high-end manufacturing with micron-level precision

Since its establishment in 2009, Chongqing Henghui Precision Mold Co., Ltd. (hereinafter referred to as Henghui Precision Molds) has specialized in the research, development, and production of micro-Precision Screws. Leveraging its exceptional micron-level manufacturing capabilities, Henghui Precision Molds has become a trusted partner for the aerospace, medical device, precision electronics, and micro-mechanics sectors. Adhering to the core philosophy of "Precision in Microscopy, Stability in Operation," the company is committed to pushing the boundaries of size and meeting the stringent requirements of high-end manufacturing for precision components.

Henghui Precision's core competitiveness stems from its micron-level machining technology, enabling mass production of a full range of micro-screws with thread sizes ranging from M0.5 to M3, with outer diameters as small as ≤1mm and thicknesses as thin as 0.05mm (e.g., stainless steel screws with washers). The company supports customized production for over 12 materials, including titanium alloy, stainless steel, copper, aluminum, and carbon steel, addressing diverse needs, from high-strength and lightweight (titanium alloy) to corrosion-resistant and conductive (copper and stainless steel).

For example, Henghui Precision utilizes precision cold heading and micron-level stamping technology to achieve integrated molding of the washer and screw, ensuring connection stability in high-vibration environments. This product is ISO 9001 certified and offers a salt spray test report (neutral salt spray test: no rust for ≥72 hours), meeting the corrosion resistance and long-term reliability requirements of medical implants, avionics, and other applications.

Facing the high-end manufacturing trend of "smaller, more precise, and more stable," Henghui Precision continues to invest in R&D, exploring nano-scale surface treatment technologies, superplastic forming processes, and expanding the application of new materials such as high-temperature alloys and shape memory alloys, to provide global customers with even more advanced precision fastening solutions.
