Mastering Complex Deep Drawing:
20+ Years of Excellence.

Hengya Stamping is a BMW-certified precision manufacturer based in Wenzhou, Zhejiang Province. We specialize in solving complex deep drawing and progressive die stamping challenges for global industry leaders — including ASSA ABLOY, BMW, HANSA-FLEX, and Xiaoguan Tea.

Founded in 2003, our factory operates in-house progressive die design and multi-stage deep draw press lines from 45T to 400T. Every RFQ receives a free DFM analysis to optimize tolerances and surface finishes — including anodizing, electropolishing, and sandblasting.

The Hengya Standard

Built on 20 Years of
Deep Drawing Expertise.

Our lead engineer has spent over two decades mastering horizontal deep drawing. He personally oversees die design for every new project, ensuring material flow, tooling geometry, and press tonnage are optimized for each part.

This is why we can achieve corner radii as small as R\u22640.3mm on 1060 aluminum \u2014 a specification that standard stamping suppliers cannot meet. It is not a machine capability; it is a knowledge capability built over decades.

Case Study \u00b7 Luxury Packaging

From BMW Filters to
Premium Tea Caddies.

Our deep drawing capability spans industrial and luxury applications. The same process that produces BMW hydraulic filter housings \u2014 requiring \u00b10.02mm dimensional tolerance \u2014 also produces the seamless aluminum tea caddies used by Xiaoguan Tea for their premium gift packaging.

Material: 1060 aluminum alloy. Wall thickness: 0.15\u20130.3mm. Surface: high-saturation anodized finish in custom colors. Defect rate: <0.1% across 200,000+ units per year.
