In the competitive world of automotive manufacturing, the quality of your tooling directly determines the quality of your finished parts. Sourcing from a reliable automotive stamping dies manufacturer is not just a procurement decision — it is a strategic move that impacts production efficiency, part consistency, and bottom-line costs. Linhai Dian Mould Co., Ltd., operating under the brand DIAN STAMPING, has been serving global automotive OEMs from its 50,000 m² facility in Zhejiang, China, since 2003. With over 20 years of hands-on experience, the company has evolved into a comprehensive one-stop manufacturing partner for the automotive industry.
At a Glance: DIAN STAMPING is a factory-direct supplier of stamping dies, sheet metal parts, checking fixtures, and welding jigs, with an annual capacity of approximately 2,000 sets of medium and small stamping dies and an annual die turnover of about RMB 50 million. The company counts KIA, BYD, Toyota, Honda, Suzuki, and Geely among its customers, with exports to more than 10 countries.
Comprehensive Capabilities Under One Roof
One of the biggest challenges automotive buyers face is managing multiple suppliers for tooling, production, and quality inspection. DIAN STAMPING solves this by offering end-to-end manufacturing services that cover the entire production chain:
Stamping Dies — Precision Tooling for Complex Parts
DIAN STAMPING designs and manufactures progressive dies, transfer dies, and tandem/multi-station dies for large and medium-sized automotive components. Whether you need progressive die stamping for high-volume production or transfer dies for complex geometries, the company's engineering team — comprising approximately 35 designers and technicians — delivers tooling solutions that meet OEM specifications. The die workshop spans approximately 4,000 m² and is equipped to handle a wide range of materials including multiphase steel, aluminum, custom rolled and welded plate, and stainless steel.
Sheet Metal Parts — From Prototype to High-Volume Production
Beyond tooling, DIAN STAMPING produces stamped sheet metal parts for automotive body-in-white, door systems, seating systems, instrument panels, fuel-tank systems, exhaust systems, clutch systems, and chassis systems. The company accepts custom orders from 2D drawings, 3D data, or physical samples, and offers prototype services to accelerate your product development cycle. For customers in the household appliance industry, the company also manufactures precision stamped components for refrigerators, washing machines, and other appliances.
Checking Fixtures and Welding Jigs — Ensuring Quality and Assembly Accuracy
Quality assurance is a critical part of automotive manufacturing. DIAN STAMPING provides high-precision checking fixture solutions designed for GD&T-oriented inspection of stamped components and welded assemblies. These fixtures enable fast, repeatable, and operator-independent quality checks on the production floor. Complementing the inspection line, the company's custom welding jigs ensure accurate positioning and repeatable welding results for automotive assemblies, reducing scrap and rework rates.
Quality Systems and Manufacturing Standards
DIAN STAMPING operates under an ISO 9001 quality management system and follows IATF 16949-oriented automotive manufacturing practices. The company's commitment to quality is reflected in its long-term relationships with major OEMs including KIA, BYD, Toyota, Honda, Suzuki, and Geely. With a planned 35,000 m² expansion featuring new press and coating lines, the company is continuously investing in capacity and capability upgrades to meet evolving industry demands.
Factory-Direct Pricing and Fast Delivery
As a factory rather than a trading company, DIAN STAMPING offers competitive pricing without compromising on quality. Typical delivery times are 30–40 days for steel stamping dies and approximately 70 days for casting stamping dies, depending on project complexity. The company's location in Linhai, Taizhou, Zhejiang Province — a well-established manufacturing hub — provides access to a mature supply chain and efficient logistics for global shipping.
