Comprehensive Product & Service Portfolio

What sets Dian Stamping apart from many stamping die manufacturers is the breadth of its capabilities. The company is not just a die maker 鈥?it is a one-stop manufacturing partner that covers the entire production chain, organized into four core categories:

1. Stamping Dies

Dian Stamping designs and builds precision stamping tooling for complex automotive and industrial parts, including progressive die stamping, transfer dies, and tandem/multi-station dies. The tooling capabilities span body-in-white components, door systems, seating systems, instrument panels, fuel-tank systems, exhaust systems, clutch systems, and chassis systems. The company processes a wide range of materials including multiphase steel, aluminum alloys, custom rolled and welded plate, and stainless steel.

2. Sheet Metal Parts

From automotive body panels and structural reinforcements to household appliance components, Dian Stamping delivers high-quality sheet metal parts produced with precision tooling. The factory offers laser cutting, bending, forming, deep drawing, welding, and surface finishing 鈥?all under one roof. Customers can provide 2D drawings, 3D CAD data, or physical samples for custom production.

3. Checking Fixtures

Every stamped part needs to be verified. Dian Stamping manufactures high-precision checking fixture solutions that allow fast, repeatable dimensional inspection of stamped components and welded assemblies. Designed in accordance with GD&T principles, these fixtures help eliminate measurement variability and ensure that every part meets OEM specifications before it moves to the next stage of production.

4. Welding Jigs
