From Tooling to Production: How DIAN STAMPING Delivers End-to-End Metal Stamping Solutions for Global Automotive OEMs
In today's competitive automotive landscape, OEMs and tier suppliers are no longer looking for just a die maker or a parts supplier. They need a manufacturing partner capable of managing the entire value chain — from die design and precision tooling to high-volume stamping, inspection, and assembly — all under one roof with consistent quality and on-time delivery.
DIAN STAMPING (Linhai Dian Mould Co., Ltd.), headquartered in Taizhou, Zhejiang Province, China, has been delivering exactly that since 2003. With a 50,000 m² production campus, approximately 110 skilled employees, and an annual output of roughly 2,000 die sets, the company has evolved into a vertically integrated manufacturing powerhouse serving some of the world's most recognizable automotive brands.
Precision Stamping Dies Engineered for Complex Automotive Applications
At the core of DIAN STAMPING's capabilities lies its expertise in designing and building high-precision stamping tooling. The company's die workshop — spanning approximately 4,000 m² and staffed by a team of around 35 die designers and technicians — specializes in three primary die technologies:
- Progressive Dies — Multi-station tooling for high-speed, high-volume production of complex stamped components with tight tolerances.
- Transfer Dies — Ideal for large, deep-drawn parts requiring multiple forming operations across separate stations.
- Tandem (Multi-Station) Dies — Designed for medium-to-large panels where part geometry demands sequential forming, piercing, and trimming operations.
These dies are engineered to handle a wide range of materials including high-strength steel (HSS), multiphase steel, aluminum alloys, custom rolled and welded plate, and stainless steel. Typical lead times range from 30-40 days for steel dies to approximately 70 days for casting dies, with the company's annual die turnover reaching roughly RMB 50 million.
High-Quality Stamping Parts Production from Prototype to Mass Production
Beyond tooling, DIAN STAMPING operates a full-scale stamping parts production line capable of handling everything from prototype development to high-volume serial production. The facility supports laser cutting, bending, forming, and welding assembly, producing components for automotive systems including body-in-white, seating, door systems, instrument panels, chassis, fuel tanks, and exhaust systems.
The company also serves the household appliance industry, manufacturing precision metal components for both domestic and international appliance OEMs. Material processing capabilities span cold-rolled steel, galvanized steel, aluminum, and stainless steel, giving customers the flexibility to source diverse part families from a single supplier.

Quality Assurance Backed by IATF 16949 and In-House Inspection
Quality is not an afterthought at DIAN STAMPING — it is embedded in every stage of the manufacturing process. The company holds ISO 9001 certification and operates its quality management system in alignment with IATF 16949 automotive standards. Every production run undergoes rigorous inspection supported by coordinate measuring machines (CMM), in-line dimensional checks, and 3D scanning where required.
A key differentiator is DIAN STAMPING's in-house checking fixture manufacturing capability. As the company notes, press dies and checking fixtures are always needed as a set. By producing both in-house, DIAN STAMPING eliminates the dimensional variances that arise when dies and fixtures come from different suppliers, ensuring that stamped parts meet design intent from the first hit.
In addition to checking fixtures, the company manufactures custom welding jigs that enable accurate, repeatable positioning during welding and assembly operations. This integrated approach to quality tooling — dies, fixtures, and jigs produced under one roof — is rare among mid-sized Chinese stamping manufacturers and represents a significant advantage for OEMs seeking supply chain simplification.
A Vertically Integrated Model That Reduces Supply Chain Risk
DIAN STAMPING's one-stop service model extends beyond die making and stamping. The company also offers in-house powder coating, electrophoresis treatment, and finished product assembly. This means customers can send in raw material specifications and receive fully finished, coated, and assembled components — without the need to coordinate multiple vendors across different regions.
This vertical integration delivers tangible benefits: shorter overall lead times, single-point quality accountability, reduced logistics costs, and simplified communication. As a factory-direct supplier — not a trading company — DIAN STAMPING offers competitive pricing combined with direct engineering access and full production visibility.
A Track Record Global Automotive Brands Rely On
Over its two decades of operation, DIAN STAMPING has built a customer portfolio that includes major automotive OEMs such as KIA, BYD, Toyota, Honda, Suzuki, and Geely. The company exports its tooling and stamped parts to more than 10 countries, serving both direct OEM programs and tier supplier partners.
Recognized as a National High-Tech Enterprise and a Zhejiang Provincial Science and Technology SME, the company continues to invest in its future. A planned 35,000 m² expansion will add new press lines, automated production capabilities, and enhanced coating facilities to meet growing global demand.
"We welcome your cooperation for long-term win-win partnerships. With stable quality, reliable lead times, and competitive pricing, we offer free solutions, tooling, and sampling."
