A Manufacturing Foundation Built Since 2003

Linhai Dian Mould Co., Ltd. (Dian Stamping) was established in 2003 in Huangyan, Taizhou, Zhejiang Province — one of China's most established manufacturing hubs. With over two decades of continuous operation, the company has grown from a specialized tooling shop into a full-spectrum manufacturer spanning automotive stamping dies, sheet metal parts, checking fixtures, and welding jigs.

Today, Dian Stamping operates a modern facility covering approximately 50,000 m², including a dedicated die workshop of 4,000 m². A planned 35,000 m² expansion featuring new press lines and advanced coating lines is already underway — signaling a clear commitment to scaling alongside its global customers.

Real Capacity, Real Numbers

When evaluating a manufacturing partner, capacity claims must be backed by real infrastructure. Dian Stamping delivers:

• 2,000+ sets of medium and small stamping dies produced annually
• 110+ employees, including approximately 35 die designers and technicians
• ~RMB 50 million in annual die turnover
• 50,000 m² total facility with ongoing expansion
• ISO 9001 quality management system, with IATF 16949-oriented practices

These are not marketing figures — they reflect the operational reality of a company that has been delivering production tooling to the world's most demanding OEMs for more than 20 years.

More Than Dies: A True One-Stop Partner

What sets Dian Stamping apart from other stamping die manufacturers is the breadth of its capabilities. The company does not stop at delivering the tool — it can take your project from raw material through to finished, weldable assembly.

Stamping Dies

Progressive dies, transfer dies, and tandem/multi-station dies for complex automotive parts. Materials processed include multiphase steel, aluminum, custom rolled and welded plate, and stainless steel. Applications span body-in-white, door systems, seating systems, instrument panels, fuel tanks, exhaust systems, clutch systems, and chassis.

Sheet Metal Parts

Beyond tooling, Dian Stamping produces high-volume stamped sheet metal parts for automotive and household appliance industries. Custom fabrication, laser cutting, bending, and welding assembly are all available in-house.

Checking Fixtures

Every stamped part needs verification. Dian Stamping designs and builds high-precision checking fixture systems aligned with GD&T standards, ensuring that each part matches its dimensional specification before it moves to the next production stage.

Welding Jigs & Assembly

Custom welding jig solutions for accurate, repeatable welding and assembly. Whether you need spot welding, MIG, or robotic welding fixtures, Dian Stamping delivers jigs designed for production-floor reliability.

OEM Trust: A Global Customer Roster

A manufacturer's reputation is only as strong as the customers it keeps. Dian Stamping has supplied tooling and parts to an impressive list of global automotive OEMs, including:

• KIA
• BYD
• Toyota
• Honda
• Suzuki
• Geely

With exports to more than 10 countries, the company has demonstrated its ability to meet international quality standards, delivery timelines, and engineering requirements across diverse vehicle platforms.

Engineering Depth: 35 Designers Driving Precision

A die is only as good as its design. Dian Stamping employs approximately 35 die designers and technicians who bring deep experience in progressive die design, transfer die engineering, and forming simulation. The company supports customization from 2D drawings, 3D data, or physical samples — and offers prototype services to validate designs before mass production.

Typical delivery timelines are 30–40 days for steel stamping dies and approximately 70 days for casting stamping dies, subject to project scope. This track record of on-time delivery is one reason OEMs return to Dian Stamping program after program.

Quality Without Compromise

Dian Stamping operates under an ISO 9001 quality management system and follows IATF 16949-oriented automotive manufacturing practices. Quality is embedded at every stage:

• In-process inspection during die manufacturing
• Checking fixture verification for stamped parts
• First-article inspection before production ramp-up
• Continuous improvement through engineering feedback loops

As a factory-direct manufacturer — not a trading company — Dian Stamping offers full traceability, direct communication with the production team, and cost advantages that come from eliminating middlemen.

Why Global OEMs Are Choosing Integrated Partners

The automotive industry is shifting toward supply chain consolidation. OEMs increasingly prefer partners who can manage multiple stages of production — from die design to stamped parts to checking fixtures to welding jigs — because it reduces lead times, simplifies quality management, and lowers total cost of ownership.

Dian Stamping's vertically integrated model addresses this trend directly. One engineering team. One quality system. One point of contact. And a single factory floor where tooling and production coexist under the same roof.
