  • Custom Stainless Steel Parts

    Runyuan manufactures custom stainless steel components using precision metal stamping, deep drawing, and secondary processing. We work with a wide range of stainless steel grades, including 304, 304L, 316, 316L, 409, and 409L, to meet your specific design and application requirements.

    Supported by in-house tooling, optimized manufacturing processes, and strict quality control, we help ensure consistent dimensional accuracy, excellent surface quality, and reliable production performance for both prototype and high-volume orders.

  • Tearing & Thinning Control

    Through optimized tooling design and process control, we help minimize material tearing and excessive thinning during deep drawing. Our engineering approach promotes uniform material flow, consistent wall thickness, and reliable structural strength for demanding applications.

  • Material & Thickness Specifications

    We stock a wide range of stainless steel grades and optimize tooling for both standard and low-carbon materials. Our production supports various thicknesses and strip widths while maintaining consistent dimensional accuracy.

    Thickness Capabilities

    Precision processing for material thicknesses from 0.5 mm to 6.0 mm with consistent quality.

    Raw Surface Protection

    Protective films for 2B, No.4, BA, and mirror finishes help minimize die marks and surface scratches during production.

  • Secondary Operations & Surface Finishing

    Beyond metal stamping, we provide complete in-house secondary operations to deliver production-ready components. Integrated processing helps reduce supplier coordination while maintaining consistent quality and efficient delivery.
