When it comes to high-volume production of automotive components, the quality of your tooling defines the quality of your output. For automotive OEMs and Tier 1 suppliers seeking a reliable partner for precision automotive stamping dies, the choice of manufacturer directly impacts part accuracy, production uptime, and total cost of ownership.

DIAN STAMPING, operating under LINHAI DIAN MOULD CO., LTD., has been serving the global automotive industry from its base in Taizhou, Zhejiang, China, since 2003. With over two decades of hands-on experience, the company has evolved from a traditional die shop into a full-service manufacturing partner capable of handling the entire lifecycle of automotive stamped components — from die design and fabrication to production stamping, welding, and assembly.

A Manufacturing Facility Built for Scale and Precision

DIAN STAMPING's current facility spans approximately 50,000 m², with a dedicated die workshop of 4,000 m². The company employs around 110 people, including 35 die designers and technicians. This infrastructure supports an annual production capacity of approximately 2,000 sets of medium and small stamping dies, with a reported annual die turnover of roughly RMB 50 million.

A new 35,000 m² facility is also underway, featuring additional press lines and coating capabilities, signaling the company's commitment to expanding capacity for growing customer demand.

Comprehensive Die Types for Every Application

As experienced stamping die manufacturers, DIAN STAMPING designs and builds a full spectrum of tooling types to meet diverse production requirements:

• Progressive dies — Ideal for high-speed, multi-station production of complex parts with tight tolerances
• Transfer dies — Suited for large and medium-sized parts requiring multiple forming operations
• Tandem / multi-station dies — Flexible solutions for lower-volume runs or parts with varying geometry

The company's die applications span critical automotive systems including body-in-white, door systems, seating systems, instrument panels, fuel-tank systems, exhaust systems, clutch systems, and chassis systems. Materials processed include multiphase steel, aluminum alloys, custom rolled and welded plate, and stainless steel.

Beyond Dies: A One-Stop Manufacturing Partner

What sets DIAN STAMPING apart from traditional tooling shops is its ability to deliver finished components — not just dies. The company's service portfolio includes:

• Sheet metal parts production — High-volume stamping of automotive and household appliance components
• Checking fixtures — Precision checking fixture solutions for GD&T-oriented inspection of stamped parts and assemblies
• Welding jigs and fixtures — Custom positioning and welding fixtures for repeatable, high-accuracy assembly
• Welding and assembly services — From spot welding to complex sub-assembly integration

This vertically integrated model means customers can move from prototype to production without juggling multiple suppliers, reducing lead times and simplifying supply chain management.

Quality Assurance and Certifications

DIAN STAMPING operates under an ISO 9001 quality management system, with manufacturing practices aligned to IATF 16949 automotive standards. The company supports customization from 2D drawings, 3D data, or physical samples, and offers prototype services for new program development.

Typical delivery timelines are 30–40 days for steel stamping dies and approximately 70 days for casting stamping dies, depending on project complexity and specification.

A Track Record of Global OEM Partnerships

DIAN STAMPING has built long-term relationships with leading automotive brands including KIA, BYD, Toyota, Honda, Suzuki, and Geely. The company exports to more than 10 countries, serving customers across Asia, Europe, and the Americas.
