When sourcing metal components for automotive manufacturing, the question is not just about finding a supplier — it is about finding a partner who can handle the entire value chain, from tooling design to high-volume production. For over two decades, LINHAI DIAN MOULD CO., LTD (Dian Stamping) has been serving global automotive OEMs as a comprehensive one-stop manufacturer of automotive stamping dies, stamped sheet metal parts, checking fixtures, and welding jigs. With a 50,000 m² facility in Taizhou, Zhejiang, and a team of 110 skilled professionals, Dian Stamping brings together precision engineering, factory-direct pricing, and vertically integrated production under one roof.
Why Vertical Integration Matters in Metal Stamping
In the automotive stamping industry, the separation of die design, die manufacturing, and part production often leads to communication gaps, quality inconsistencies, and extended lead times. Dian Stamping eliminates these risks by offering a fully integrated service model. From the initial concept and CAD/CAM engineering in AutoCAD, SolidWorks, and CATIA to precision machining, tryout, and mass production, every stage is managed in-house. This approach ensures that each die set is optimized not only for its own performance but also for the downstream stamping process, resulting in higher part quality and longer tool life.
The company's die workshop spans approximately 4,000 m² and produces an annual capacity of about 2,000 sets of medium and small stamping dies. With a reported annual die turnover of approximately RMB 50 million, Dian Stamping has demonstrated consistent capability in serving both high-volume production lines and customized low-to-medium volume projects.
Comprehensive Stamping Die Capabilities
Dian Stamping specializes in a wide range of die types designed to meet the varying demands of automotive part manufacturing. The company's core die offerings include:
| Die Type | Best For | Key Advantage |
|---|---|---|
| Progressive Dies | High-volume, complex parts with multiple operations | Single-pass efficiency; blanking, forming, punching, and cutoff in one continuous feed |
| Transfer Dies | Large and medium-sized complex components | Flexible station arrangement for deep-drawn and intricate geometries |
| Tandem Dies | Car body structural components with high-tensile materials | Handles advanced high-strength steel (AHSS) and multiphase materials |
As a dedicated progressive die stamping manufacturer, Dian Stamping combines advanced die design with rigorous tryout testing to ensure that each tool delivers consistent, repeatable results across its entire production life.
Beyond Dies: Sheet Metal Parts, Checking Fixtures, and Welding Solutions
What sets Dian Stamping apart from traditional tooling shops is its ability to extend services beyond die manufacturing into full production and quality assurance. The company's sheet metal parts division offers laser cutting, bending, welding, and powder coating, serving automotive, household appliance, and industrial sectors. Customers can move from prototype to production seamlessly, with the same team managing both the tooling and the stamped output.
Quality verification is another area where Dian Stamping adds unique value. The company designs and builds custom checking fixture solutions that are GD&T-compliant, enabling rapid and repeatable dimensional inspection of stamped components. Press dies and checking fixtures are often delivered as a matched set, eliminating the common mismatch between production tooling and inspection equipment. In addition, the company's welding jig division provides robotic MIG welding, spot welding, and custom jig design services, covering the full assembly spectrum from individual brackets to complex body-in-white subassemblies.
Material Expertise Across the Automotive Platform
Modern automotive engineering demands versatility in material processing. Dian Stamping has built deep expertise in working with multiphase (advanced high-strength) steel, aluminum alloys, custom rolled and welded plate, and stainless steel. These materials are critical for lightweighting, crash performance, and corrosion resistance in today's vehicle platforms. The company's planned 35,000 m² expansion facility, featuring new press lines and coating capabilities, will further strengthen its ability to process advanced materials at scale.

Quality Systems and Global Customer Base
Dian Stamping operates under a quality management system that is ISO 9001 certified and follows IATF 16949-oriented automotive manufacturing practices. This commitment to quality has earned the trust of global OEMs including KIA, BYD, Toyota, Honda, Suzuki, and Geely, with exports reaching more than 10 countries across Asia, Europe, and the Americas. The company's position as a factory-direct source — not a trading company — means customers benefit from competitive pricing, direct engineering communication, and full transparency throughout the project lifecycle.
Key Quality Highlights: ISO 9001 certified | IATF 16949-oriented practices | 35+ die designers and technicians | GD&T-compliant inspection | Free metal samples available for qualification
Frequently Asked Questions
What is the typical lead time for stamping dies from Dian Stamping?
For steel stamping dies, typical delivery is 30-40 days. Casting stamping dies generally require approximately 70 days, depending on the complexity and specific project requirements. The company offers prototype services for customers who need to validate designs before full production tooling.
Can Dian Stamping work from customer drawings or samples?
Yes. Dian Stamping accepts 2D drawings, 3D CAD data (in formats compatible with AutoCAD, SolidWorks, and CATIA), or physical samples for reverse engineering. Customization is available at every stage of the process.
Does Dian Stamping offer both tooling and production services?
Absolutely. One of the company's core strengths is its vertically integrated model: customers can engage Dian Stamping for die design and manufacturing, production stamping, checking fixture supply, and welding jig fabrication — all from a single supplier. This reduces coordination overhead and ensures quality consistency from tooling to final part.
What materials can Dian Stamping process?
The company processes multiphase (advanced high-strength) steel, aluminum alloys, custom rolled and welded plate, and stainless steel. This material versatility makes Dian Stamping suitable for a wide range of automotive applications including body-in-white, chassis, and powertrain components.
