When automotive engineers design a new vehicle, every component must meet exacting standards for safety, durability, and precise fit. Behind every stamped metal part that goes into a car door, chassis frame, or seating system lies a carefully engineered tool — the stamping die. Choosing the right partner for automotive stamping dies is not just about finding a supplier; it is about building a relationship with a manufacturer that understands the full complexity of modern vehicle production, from material science to high-volume assembly.

With a 50,000-square-meter facility in Linhai, Taizhou, Zhejiang Province, and a track record of serving OEMs including KIA, BYD, Toyota, Honda, Suzuki, and Geely, DIAN STAMPING (LinHai Dian Mould Co., Ltd.) has established itself as a reliable partner for the global automotive supply chain. The company exports its products to more than 10 countries and continues to expand its capacity with a planned 35,000-square-meter facility featuring advanced press and coating lines.

At the core of DIAN STAMPING's operations is a comprehensive die manufacturing capability that covers the most widely used stamping technologies in the automotive industry. The company designs and builds progressive dies, transfer dies, and tandem dies, each optimized for specific production requirements. A progressive stamping die performs multiple operations — blanking, forming, punching, coining, and cutoff — in a single press cycle, making it the preferred choice for high-volume production of small to medium-sized components. Transfer dies handle large, geometrically complex parts, while tandem dies are engineered for car body structural components made from high-tensile-strength materials.

The die workshop spans approximately 4,000 square meters and is staffed by roughly 35 experienced die designers and technicians. Using industry-standard CAD/CAM tools — AutoCAD, SolidWorks, and CATIA — the engineering team develops tooling solutions that are fine-tuned to each customer's part geometry, material specifications, and production volume targets. The facility's annual capacity reaches approximately 2,000 sets of medium and small stamping dies, with an annual die turnover of approximately RMB 50 million.

DIAN STAMPING distinguishes itself by offering a fully integrated manufacturing service that extends well beyond die production. The company provides end-to-end solutions that include metal stamping, welding, powder coating, assembly, and quality inspection — all under one roof. This integrated model means customers can source custom sheet metal parts, welded assemblies, and finished components from a single supplier, eliminating the coordination overhead and quality variability that come with managing multiple vendors.

The metal stamping division produces precision components for a wide range of automotive systems, including body-in-white structures, door systems, seating systems, instrument panels, exhaust systems, fuel tanks, chassis components, and clutch systems. Additional processing capabilities include laser cutting, bending, robotic MIG welding, spot welding, and powder coating. The company's ability to handle prototyping, tooling development, and mass production within a single facility gives customers faster time-to-market and tighter control over product quality.

In the automotive industry, quality certification is a prerequisite for supplier qualification. DIAN STAMPING operates under ISO 9001 and IATF 16949 quality management systems, and has earned TUV certification for product safety. These standards govern every aspect of production, from raw material sourcing and in-process inspection to final dimensional verification and packaging.

The company designs and builds its own checking fixtures and welding jigs — precision tools that enable rapid, repeatable dimensional verification of stamped components. These fixtures are GD&T-compliant and are often delivered as a matched set with the stamping dies themselves, ensuring that every part produced meets the specified tolerances before it leaves the factory floor. This in-house quality infrastructure gives customers confidence that components arriving at their assembly lines will fit correctly the first time, every time.

As automotive manufacturers pursue lightweighting strategies to improve fuel efficiency and extend electric vehicle range, the demand for advanced materials has grown significantly. DIAN STAMPING has developed proven processing capabilities for multiphase steel, aluminum alloys, custom rolled steel and welded plate, and stainless steel. This material versatility allows the company to support a broad range of applications, from high-strength structural components to corrosion-resistant exterior parts, while maintaining the tight tolerances required by automotive engineering teams.

DIAN STAMPING has been recognized as a National High-Tech Enterprise and a Zhejiang Provincial Technology-based SME. The company operates a dedicated R&D laboratory focused on advancing die coating technologies, process simulation, and smart manufacturing integration. Its portfolio of patented technologies is applied directly to production tooling, giving customers access to innovations that improve die life, reduce cycle times, and enhance part quality.

The company's affiliated entities — Linhai Diyao New Technology Co., Ltd. and Taizhou Elay International Trade Co., Ltd. — support ongoing research and international trade operations. A planned expansion of 35,000 square meters will add new press lines, automated welding cells, and advanced coating lines, further strengthening DIAN STAMPING's position as a competitive, scalable manufacturing partner.
