20+ Years of Precision: Why Automotive Stamping Dies from DIAN STAMPING Give You a Competitive Edge
How a Chinese factory with 50,000 m² of manufacturing capacity helps global OEMs deliver quality at scale
In the automotive industry, the quality of your stamped components directly affects vehicle safety, assembly fit, and production cost. Yet finding a stamping partner who balances precision, capacity, and cost competitiveness is harder than ever. Rising material costs, tighter tolerance requirements, and compressed program timelines demand a supplier that can deliver on all fronts.
LINHAI DIAN MOULD CO., LTD (DIAN STAMPING), established in 2003 in Taizhou, Zhejiang, has spent over two decades building exactly that capability. With a 50,000 m² facility, a dedicated 4,000 m² die workshop, and a team of 110 employees — including 35 die designers and technicians — the company produces approximately 2,000 sets of medium and small stamping dies annually. Its customers include KIA, BYD, Toyota, Honda, Suzuki, and Geely, with exports reaching more than 10 countries.
More Than Just Dies: A One-Stop Manufacturing Partner
DIAN STAMPING is not a trading company — it is a factory that covers the entire production chain. The company specializes in precision automotive stamping dies, sheet metal parts, and complementary services that many die shops cannot offer in-house.
Its four main product lines cover the full spectrum of automotive metal forming:
- Stamping Dies — Progressive, transfer, and tandem dies for large and medium-sized complex parts, supporting body-in-white, door systems, seating systems, instrument panels, and chassis applications.
- Sheet Metal Parts — Custom stamping and fabrication for automotive body panels, structural components, and even household appliance parts such as refrigerator brackets, hinges, and evaporator panels.
- Checking Fixtures — High-precision, GD&T-oriented inspection fixtures that confirm every stamped part meets dimensional specifications before it reaches the assembly line. As the company notes, press dies and checking fixtures are always needed as a set.
- Welding Jigs — Custom fixtures for accurate, repeatable welding and assembly, ensuring consistent quality in welded sub-assemblies.

Years of Industry Experience
The company offers progressive die stamping, transfer die stamping, and tandem/multi-station stamping for a wide range of materials — including multiphase steel, aluminum alloys, custom rolled and welded plate, and stainless steel. Prototype services are available, and customers can submit part requirements via 2D drawings, 3D data, or physical samples for custom solutions.
Quality management follows ISO 9001 standards, with IATF 16949-oriented practices woven into the manufacturing process. In-line inspections, 3D scanning (CMM), and strain analysis are applied to ensure every component meets OEM specifications.
Typical Lead Times
Steel stamping dies: 30–40 days | Casting stamping dies: approximately 70 days
All timelines are subject to project scope and complexity. A planned 35,000 m² expansion with new press and coating lines will further reduce turnaround times.

Application Breadth: From Body-in-White to Home Appliances
While DIAN STAMPING is best known for automotive stamping, its capabilities extend well beyond passenger vehicles. The product catalog covers 82 archived products across body-in-white (rear outer panels, side frames, spare tire wells, A-pillar reinforcements), door systems (hinge reinforcement plates, water-cut panels), seating systems (seat basins, support beams, battery cases), instrument panels, exhaust system heat shields, and chassis components.
In the household appliance segment, the company produces precision brackets, hinges, handles, and evaporator panels for refrigerators, washing machines, and ovens — all manufactured to the same tight tolerances as its automotive work.
Why Global Buyers Choose DIAN STAMPING
For procurement and engineering teams evaluating new stamping partners, DIAN STAMPING offers several distinct advantages:
- Factory-direct pricing — No middleman margins. The company owns its tooling, presses, and finishing lines.
- End-to-end service — From die design and prototyping to stamping, welding, inspection, and assembly, all under one roof.
- Proven OEM track record — Supplying KIA, BYD, Toyota, Honda, Suzuki, and Geely across multiple vehicle programs.
