High-Precision 0.01mm Multi-stage Deep Drawing Part for Automotive & Medical Applications

Our High-Precision Multi-stage Deep Drawing Parts represent the pinnacle of modern metal transformation technology. Specifically engineered for the rigorous safety standards of the Automotive industry and the uncompromising hygiene requirements of the Medical sector, these components are manufactured using a continuous, multi-station forming process.

Unlike traditional stamping, our progressive deep drawing technique allows for the creation of complex, hollow, and seamless cylindrical or rectangular geometries from flat metal sheets. By utilizing high-speed transfer presses and ultra-hard tungsten carbide dies, we achieve extreme depth-to-diameter ratios while maintaining uniform wall thickness. This cold-forming process not only ensures structural integrity but also enhances the material's tensile strength through work hardening, providing a lightweight yet incredibly durable solution for critical applications.

• Micron-Level Precision: We maintain tolerances as tight as ± 0.005mm, meeting the high-spec requirements for life-critical medical devices and engine sensors.
• Complex Internal Geometries: Capability to produce parts with multi-step diameters, internal ribbing, and specialized necking without secondary machining.
• Superior Surface Finish: Achieving a Ra 0.4-0.8 smoothness directly from the press, reducing the need for intensive polishing or grinding.
• Material Efficiency: Up to 30%-50% less waste compared to CNC turning, significantly lowering the unit cost for high-volume production.
• High Repeatability: Automated multi-stage sensors ensure that the 1st part and the 1,000,000th part are identical in dimension and quality.

In the automotive sector, reliability is non-negotiable. Our deep-drawn parts are used in Fuel Injection Systems (injector sleeves), Braking Systems (ABS valve housings), and EV Battery Technology (battery cell cans and cooling connectors). These parts withstand high pressure and extreme thermal cycles without leaking or fatigue.

We don't just manufacture; we engineer. Our Design for Manufacturing (DFM) service helps you optimize your part's geometry to minimize production stages and material cost.

• In-house Tooling: Custom design and fabrication of progressive dies.
• Rapid Prototyping: 3D-printed metal samples or soft-tooling runs for functional testing before mass production.
• Material Sourcing: Specialized sourcing of high-purity medical alloys or high-strength automotive steels.

• Engineering Consultation: Free technical feasibility analysis for new designs.
• Quality Assurance: 100% automated optical inspection (AOI) and CMM reporting.
• Global Logistics: Door-to-door delivery with full customs clearance support.

• Packaging: Standard anti-rust (VCI) bags, custom blister trays for scratch-sensitive parts, and vacuum packaging for medical components.
