When sourcing a stamping die partner, most buyers focus on the tool itself. But in automotive manufacturing, the real value lies in a supplier's ability to deliver precision tooling, high-volume stamped parts, inspection fixtures, and welding solutions under one roof — with consistent quality, competitive pricing, and a track record that global OEMs trust.
DIAN STAMPING (Linhai Dian Mould Co., Ltd.), established in 2003 in Taizhou, Zhejiang Province, has spent more than two decades evolving from a specialized tool-and-die workshop into a comprehensive manufacturing partner for the global automotive industry. With a 50,000 m² modern facility, approximately 110 employees, and an annual die output of roughly 2,000 sets, the company delivers end-to-end solutions that go far beyond the press.
Precision Tooling for Complex Automotive Applications
As a seasoned stamping die manufacturers, DIAN STAMPING specializes in three core die technologies: progressive dies, transfer dies, and tandem (multi-station) dies. These are engineered for a wide spectrum of automotive components — body-in-white panels, door systems, seating structures, instrument panels, chassis components, fuel-tank systems, and exhaust systems.
The company's automotive stamping dies are designed to handle high-strength steel (HSS), multiphase steel, aluminum alloys, custom rolled and welded plate, and stainless steel. This material versatility is increasingly critical as OEMs push for lighter, stronger, and more crash-resistant vehicle structures.
Die Workshop: Approximately 4,000 m² dedicated to die manufacturing
Design Team: Around 35 die designers and technicians
Annual Die Turnover: Approximately RMB 50 million
Typical Lead Time: 30-40 days for steel dies, ~70 days for casting dies

A One-Stop Manufacturing Ecosystem
What truly sets DIAN STAMPING apart is its vertically integrated service model. Beyond die manufacturing, the company offers three additional capabilities that eliminate the need for customers to coordinate multiple vendors:
Sheet Metal Parts Production — From prototype to high-volume stamping runs, including laser cutting, bending, forming, and welding assembly. The facility handles both automotive and household-appliance stamping with materials ranging from cold-rolled steel to aluminum and galvanized steel.
Checking Fixtures — High-precision inspection tools built to GD&T standards, enabling rapid dimensional verification of stamped components. As the company notes, press dies and checking fixtures are always needed as a set, and a well-designed checking fixture eliminates individual measurement variances on the production floor.
Welding Jigs — Custom positioning fixtures for accurate, repeatable welding and assembly operations, supporting everything from spot welding to complex assembly sequences.
Quality Built In, Not Inspected On
DIAN STAMPING operates under an ISO 9001 quality management system, with manufacturing practices aligned to IATF 16949 automotive standards. Every die and production part undergoes rigorous inspection, supported by in-line checks, coordinate measuring machine (CMM) verification, and 3D scanning where required.
Custom orders are accepted from 2D drawings, 3D CAD data, or physical samples. Prototype services are available for new vehicle programs, and the company's design team uses industry-standard software to optimize die structure, strip layout, and forming simulation before any steel is cut.
A Track Record Global OEMs Trust
DIAN STAMPING's customer base includes major automotive names such as KIA, BYD, Toyota, Honda, Suzuki, and Geely, with exports spanning more than 10 countries. The company positions itself as a factory-direct supplier — not a trading company — which means customers benefit from competitive pricing, direct engineering communication, and full visibility into the manufacturing process.
With a modern facility covering approximately 50,000 m² and a planned 35,000 m² expansion featuring new press lines and coating capabilities, DIAN STAMPING is investing in the capacity to meet growing demand from both existing and new customers.
