Due to direct human contact or use in critical medical devices, medical fasteners face extremely stringent performance requirements. Bolts for surgical instruments demand micron-level precision and corrosion resistance; implantable fasteners require biocompatibility and mechanical compatibility; and fasteners for rescue equipment must possess high strength and fatigue resistance. With 12 years of expertise in medical fasteners, Dongguan Lizheng has established a full-process quality control system spanning material R&D, precision forming, and surface treatment. Our products have passed multiple international certifications, including EU CE, US FDA, and China CFDA, making us a core supplier for renowned enterprises such as Siemens Healthineers, Mindray, and Zoomlion.
In the emergency rescue equipment sector, Dongguan Lizheng's high-precision brass fasteners have become a market focal point. Manufactured from HPb59-1 high-precision brass using multi-station cold heading processes, these products maintain dimensional tolerances within ±0.01mm and achieve a tensile strength of 420MPa, meeting the high-frequency, high-intensity demands of rescue operations. To address harsh outdoor environments, we developed an eco-friendly chromium-free passivation coating. This coating achieves a salt spray test result of 1,500 hours—far exceeding the industry standard of 800 hours—and is free of heavy metals, fully complying with the EU RoHS directive. In March 2025, when Zoomlion urgently needed a high-strength, corrosion-resistant precision bolt for its next-generation emergency rescue robot, Dongguan Lizheng completed the customized development in just 15 days. After passing 100,000 fatigue tests without fracture, the product was successfully adopted for the robot's robotic arm connection. Orders reached 3 million units in the first half of the year, exceeding 20 million RMB in value. Additionally, this product entered the Bosch rescue equipment supply chain for earthquake demolition tools, driving an 85% year-on-year increase in export volume.
In the high-end medical equipment sector, Dongguan Lizheng's stainless steel precision fasteners hold a dominant position. To counter strong magnetic fields in MRI equipment, we developed non-magnetic stainless steel bolts using austenitic 316L material and specialized heat treatment. With magnetic permeability ≤1.005, they ensure imaging remains undisturbed. These bolts are now supplied in bulk for Siemens Healthineers' 3.0T MRI equipment at 80 RMB per unit, with H1 shipments reaching 1.5 million pieces. In the surgical instrument field, our titanium alloy micro-screws feature a diameter of only 1.2mm and weigh just 0.5g. Utilizing laser welding technology with a surface roughness of Ra0.1μm, they are ideal for laparoscopic instrument joints. Successfully replacing imported products at a price 40% lower, we have become the exclusive supplier for Mindray.
To seize market opportunities, Dongguan Lizheng invested 200 million RMB in April 2025 to build a smart factory for medical fasteners. Introducing 12 fully automated precision cold heading production lines and AI visual inspection systems, production efficiency increased by 50%, while the defect rate dropped from 0.8% to 0.2%. Concurrently, in partnership with South China University of Technology, we established the "Medical Fastener Material R&D Center." We are focusing on absorbable magnesium alloy implant screws, which can fully degrade in the human body within 2-3 years, eliminating the need for secondary surgeries. Currently in clinical trials, industrialization is expected by 2026.
Industry data projects the global medical fastener market will exceed 20 billion USD by 2030, with a compound annual growth rate (CAGR) of 12%. The General Manager of Dongguan Lizheng stated that the company will focus on implantable fasteners and high-end equipment fasteners, aiming to break through 500 million RMB in medical sector revenue by 2027 and become a global leader in the medical fastener industry.
