At Henan San Kuang Machinery Technology Co., Ltd., we specialize in delivering high-precision CNC machining for medical device components using premium 304 stainless steel. With over a decade of experience since 2014, our factory spanning 10,000–30,000 square meters is equipped with advanced CNC machines to meet the stringent requirements of the healthcare industry. Our commitment to quality and precision ensures that every component we produce meets the highest standards of reliability and performance. Leveraging a skilled team of 51–100 employees, we provide tailored solutions for clients worldwide, from prototype development to mass production.
Our 304 stainless steel CNC machining offers exceptional corrosion resistance, biocompatibility, and mechanical strength, making it ideal for surgical instruments, implantable devices, diagnostic equipment, and other medical applications. The material's non-magnetic properties and ability to withstand repeated sterilization cycles ensure long-term durability in critical environments. We employ state-of-the-art multi-axis CNC machines to achieve complex geometries and tight tolerances, with standard precision down to ±0.01mm and high-precision options of ±0.005mm. This level of accuracy reduces assembly time and enhances the overall performance of your medical device.
Key technical specifications and available options are summarized below:
| Parameter | Specification |
| Material Grade | 304 Stainless Steel (UNS S30400, EN 1.4301) |
| Tolerance (Standard) | ±0.01mm |
| Tolerance (High Precision) | ±0.005mm (available upon request) |
| Surface Roughness (Ra) | 0.4μm – 0.8μm (as-machined) |
| Available Surface Finishes | Passivation, Electropolishing, Bead Blasting, Mechanical Polishing |
| Lead Time (Prototypes) | 7–15 working days |
| Lead Time (Production) | 15–30 working days, depending on volume |
| Quality Control | In-process inspection, CMM, and final testing |
Beyond precision, we offer a range of value-added services including design for manufacturability (DFM) consultation, custom packaging, and just-in-time delivery to support your supply chain. Our team works closely with you to optimize part geometry for cost-effective production without compromising quality. For medical devices, we can also provide documentation packages including material certificates, inspection reports, and traceability records to meet regulatory requirements.
The benefits of choosing our CNC machining services for your 304 stainless steel medical components include:
- High repeatability – ensures consistent quality across large production runs.
- Complex geometry capability – allows for intricate features and tight internal cavities.
- Cost efficiency – reduces secondary operations and material waste.
- Fast turnaround – rapid prototyping to accelerate your product development cycle.
- Global compliance – our processes align with ISO 9001, ISO 14001, and OHSAS 18001 standards.

Frequently Asked Questions (FAQ)
-
Q: What materials do you use for medical device components?
A: We primarily use 304 stainless steel (1.4301), which offers excellent corrosion resistance and biocompatibility. Other medical-grade materials such as 316L, titanium, and PEEK are also available upon request. -
Q: Can you achieve tight tolerances for complex geometries?
A: Yes, our standard tolerance is ±0.01mm, and we can achieve ±0.005mm for high-precision requirements. Our multi-axis CNC machines can handle complex shapes with undercuts, threads, and fine features. -
Q: Do you provide surface finishing services?
A: Absolutely. We offer passivation, electropolishing, bead blasting, and mechanical polishing to improve corrosion resistance, reduce friction, or achieve a specific appearance. Finishing is customizable based on your application. -
Q: What is your typical lead time for prototypes?
A: Prototype lead time is 7–15 working days, depending on complexity and quantity. For production orders, lead time ranges from 15–30 working days. We also offer expedited services for urgent projects. -
Q: Do you have certifications for medical device manufacturing?
A: Our company holds ISO 9001, ISO 14001, OHSAS 18001, and other certifications. While we are not specifically ISO 13485 certified, we follow strict quality control procedures and can provide traceability and documentation to support your regulatory submissions. -
Q: Can you handle both small and large volume orders?
A: Yes, we are flexible. We accept orders from single prototypes to high-volume production runs (thousands of parts per month). Our scalable capacity ensures consistent quality regardless of quantity. -
Q: How do you ensure quality control?
A: We implement in-process inspection using CMM, optical comparators, and surface roughness testers. Final inspection includes dimensional verification, material certification, and functional testing as required. Detailed inspection reports are provided with each shipment. -
Q: What is the minimum order quantity (MOQ)?
A: There is no strict MOQ for prototypes. For production orders, we typically recommend a minimum of 100 pieces to optimize cost, but we can discuss based on your specific needs.
