What metal stamping processes do you specialize in?

Our core processes include progressive die stamping (high-volume precision parts), deep draw stamping (seamless shells, cups, enclosures up to 250mm depth), transfer die stamping (large complex parts up to 800mm), high-speed stamping (up to 300 SPM for micro-parts), and sheet metal forming/bending. We also offer fineblanking for near-net-shape precision components.

What materials can you stamp, and what thickness range do you support?

We stamp a comprehensive range: carbon steel (SPCC, Q235, 0.3–6mm), stainless steel (304/304L, 316/316L, 430, 301, 0.1–4mm), aluminum alloys (1100, 3003, 5052, 6061, 0.2–5mm), copper & brass (C110, C260, C172, 0.05–3mm), phosphor bronze, beryllium copper, and specialty alloys including Inconel and titanium. Foil as thin as 0.05mm and plate up to 12mm can be accommodated for specific processes.

Can you handle both prototype and high-volume production?

Absolutely. We support the full production lifecycle: prototype stamping (1–1,000 pieces using 3D-printed or soft tooling), bridge/low-volume production (500–10,000 pieces with quick-change tooling), and high-volume mass production (100,000 to 10+ million pieces annually with hardened progressive and transfer dies). Our 50+ press lineup from 25 to 500 tons ensures we match the right equipment to your volume.

What secondary operations and value-added services do you provide?

We offer a complete turnkey solution: in-house tooling design and die manufacturing, surface finishing (electroplating, anodizing, powder coating, passivation, electropolishing, PVD coating), heat treatment, welding (spot, projection, laser), riveting and PEM stud insertion, CNC machining for hybrid parts, automated assembly, and custom packaging. This eliminates multi-vendor logistics and quality risks.

What quality certifications and inspection capabilities do you have?

We hold ISO 9001:2015 and IATF 16949:2016 certifications with annual third-party audits. Our quality lab features CMM (Coordinate Measuring Machines), optical comparators, vision measurement systems, surface roughness testers, hardness testers, and salt spray chambers. We implement SPC (Statistical Process Control), PPAP documentation, FMEA analysis, and full material traceability from mill certificate to finished part.
