In the fast-paced world of automotive manufacturing, the quality of every stamped component directly impacts vehicle safety, performance, and production efficiency. From body-in-white structures to seating systems and exhaust assemblies, precision tooling is the backbone of modern vehicle production. Choosing the right partner for automotive stamping dies is not just a procurement decision — it is a strategic investment in your supply chain reliability.

DIAN STAMPING, operating under LINHAI DIAN MOULD CO., LTD, has been at the forefront of this industry since 2003. Based in Huangyan, Taizhou, Zhejiang Province — a region renowned as China's "Die Village" — the company combines deep-rooted manufacturing heritage with modern engineering capabilities to serve automotive clients across more than 10 countries.

A Proven Track Record with Global Automotive Brands

Experience matters in die manufacturing. DIAN STAMPING has spent over two decades refining its design and production processes, earning the trust of major automotive OEMs including KIA, BYD, Toyota, Honda, Suzuki, and Geely. This track record demonstrates not only technical competence but also the ability to meet the rigorous quality and delivery standards demanded by the global automotive industry.

As one of the leading stamping die manufacturers in China, DIAN STAMPING operates as a direct factory rather than a trading company. This means clients benefit from factory-direct pricing, direct communication with the production team, and full visibility into the manufacturing process — from initial die design to final tryout and delivery.

Manufacturing Scale and Technical Capabilities

DIAN STAMPING's manufacturing infrastructure is built to handle high-volume, precision-critical projects. The company's modern facility spans approximately 50,000 m², with a dedicated die workshop of 4,000 m². With around 110 employees — including approximately 35 die designers and technicians — the company maintains an annual production capacity of about 2,000 sets of medium and small stamping dies, with a reported annual die turnover of approximately RMB 50 million.

A planned new 35,000 m² facility featuring advanced press lines and coating capabilities is also in development, further expanding the company's ability to serve growing client demands. Materials processed include multiphase steel, aluminum alloys, custom rolled and welded plate, and stainless steel — covering the full spectrum of modern automotive material requirements.

Comprehensive Product and Service Portfolio

DIAN STAMPING offers a complete range of services under one roof, making it a true one-stop manufacturing partner for automotive clients. The company's product lines are organized into four core categories, each supported by deep engineering expertise:

• Stamping Dies — Precision progressive dies, transfer dies, and tandem dies for large and medium-sized complex automotive parts, covering body-in-white, door systems, seating systems, and chassis components.
• Sheet Metal Parts — Custom automotive and household-appliance stamping, sheet-metal fabrication, laser cutting, welding assemblies, and powder coating services.
• Checking Fixture — High-precision, GD&T-oriented inspection fixtures for stamped components and welded assemblies, ensuring dimensional accuracy and eliminating measurement variability.
• Welding Jig — Custom welding fixtures and jigs designed for accurate, repeatable production welding, supporting both manual and robotic welding processes.

A checking fixture is essential for any production environment where dimensional accuracy is critical. DIAN STAMPING designs and manufactures checking fixtures that allow rapid, repeatable inspection of stamped parts, eliminating individual measurement differences and ensuring every component meets the specified tolerances before it moves to the next stage of production.

Quality Assurance and Certification

Quality is the foundation of DIAN STAMPING's service commitment. The company operates under an ISO 9001 quality management system, with manufacturing and quality practices aligned with IATF 16949-oriented automotive standards. This ensures that every die, fixture, and stamped part meets the stringent requirements of the automotive industry.

Key quality assurance practices include in-line inspections during production, 3D scanning (CMM) for dimensional verification, and comprehensive checking fixture validation for all critical components. Free metal samples are available upon request (with freight paid by the customer), allowing potential clients to evaluate quality firsthand before committing to full production.

Customization and Delivery Flexibility

Every automotive project is unique, and DIAN STAMPING provides full customization from 2D drawings, 3D data, or physical samples. Prototype services are available for new vehicle programs, enabling rapid iteration and validation before mass production.

Typical delivery times are 30–40 days for steel stamping dies and approximately 70 days for casting stamping dies, subject to project complexity and requirements. This combination of customization capability and reliable delivery makes DIAN STAMPING a preferred partner for both Tier 1 suppliers and OEMs seeking efficient, cost-effective tooling solutions.
