What We Make.
Industry-focused metal forming solutions — from EMI shielding cans to EV battery housings. Each category is backed by dedicated tooling, alloy expertise, and in-house surface finishing.
Electronics & Shielding
Deep-drawn copper EMI/RFI shielding cans and precision battery contact strips. Seamless walls, consistent conductivity, high-volume progressive die production.
Automotive & Energy Storage
Heavy-gauge structural brackets (up to 4mm) with pressed reinforcement ribs and deep-drawn EV battery housings. 500T press line for industrial-grade forming.
Stainless Steel Deep Drawing
High-aspect ratio, seamless components in 304 & 316L, with precision tolerances down to ±0.05mm. Thin uniform walls (1.0–1.5mm), zero weld lines, corrosion-resistant — ideal for sensor housings, flow meter sleeves, and medical enclosures.
Luxury Packaging & Aesthetics
Anodized aluminum cosmetic caps in 5 premium colors and mirror-polished SS decorative covers. Zero-scratch surface protection, Ra ≤ 0.4μm, in-house anodizing and sandblasting.

Our Hard Commitments.
12-Hour DFM Feedback
Send your 2D/3D drawings and we return a DFM report within 12 hours — identifying wall thickness risks, tooling constraints, and tolerance conflicts before you commit to tooling cost.
In-House Tooling
All tooling designed and built in-house. No outsourced dies, no third-party delays. Tooling lead time: 15–25 days. All dies remain your property after first production run.
ISO 9001 Certified
Every shipment includes mill certificate, CMM inspection report, and COC. PPAP and FAI available on request. Traceability from raw coil to finished part — required for automotive and medical supply chains.
One of Only 6 Large-Scale
Horizontal Deep Drawing
Machines in China.
While most stamping factories rely on standard vertical presses, Hengya Stamping operates one of only six military-grade horizontal deep drawing machines in the entire country. This rare equipment enables us to achieve draw depths and wall-thickness tolerances that are physically impossible on conventional machinery.
