How a 20-year Chinese die manufacturer delivers quality, speed, and cost efficiency to automotive brands worldwide
When global automotive OEMs and Tier 1 suppliers evaluate tooling partners, they look beyond price. They need a manufacturer that combines engineering depth, production scale, consistent quality, and proven delivery discipline. For more than two decades, LINHAI DIAN MOULD CO., LTD — operating as Dian Stamping Company — has been that partner for brands including KIA, BYD, Toyota, Honda, Suzuki, and Geely, exporting to more than 10 countries across Asia, Europe, and the Americas.
As one of China's experienced stamping die manufacturers, Dian Stamping offers a complete ecosystem of tooling and metal-forming services under one roof — from design and die manufacturing to stamping, welding, inspection, and assembly. This article explores what makes Dian Stamping a trusted choice for automotive stamping dies and related services.
A Manufacturing Facility Built for Scale
Dian Stamping operates from a modern facility covering approximately 50,000 m² in Huangyan, Taizhou, Zhejiang Province — a region long recognized as a hub for precision mold and die manufacturing. Within this campus, a dedicated die workshop of approximately 4,000 m² houses the company's core tooling operations. A new 35,000 m² facility featuring advanced press lines and coating systems is also underway, reflecting the company's commitment to continuous capacity expansion.
The company's annual output stands at approximately 2,000 sets of medium and small stamping dies, with an annual die turnover of approximately RMB 50 million. This scale is supported by a team of around 110 employees, including approximately 35 skilled die designers and technicians who bring deep expertise in progressive, transfer, and tandem die design.

Comprehensive Die and Tooling Capabilities
Dian Stamping designs and manufactures a full spectrum of stamping dies tailored to automotive body-in-white, door systems, seating systems, instrument panels, fuel-tank systems, exhaust systems, clutch systems, and chassis systems. The company's die portfolio includes:
Progressive Dies — Ideal for high-volume production of complex parts requiring multiple forming operations in a single pass. Progressive dies from Dian Stamping deliver consistent dimensional accuracy and reduce handling between operations.
Transfer Dies — Designed for medium-to-large parts where individual stations are linked by a transfer system, enabling efficient production of deep-drawn and intricately shaped components.
Tandem / Multi-Station Dies — A flexible approach for large panels and structural parts, where each station performs a dedicated operation and parts move sequentially through the press line.
The company processes a wide range of materials including multiphase steel, aluminum, custom rolled and welded plate, and stainless steel — ensuring that it can meet the diverse material specifications of global automotive programs.
Beyond Dies: A One-Stop Manufacturing Partner
What sets Dian Stamping apart from many pure die shops is its ability to provide end-to-end manufacturing services that extend well beyond tooling. The company operates as a fully integrated factory — not a trading company — which means customers benefit from direct factory pricing, streamlined communication, and shorter lead times.
Four Core Service Lines
Stamping Dies — Precision tooling for complex automotive and industrial parts, including progressive, transfer, and tandem dies.
Sheet Metal Parts — High-volume stamped components for automotive and household appliance applications, with capabilities in laser cutting, bending, forming, and welding.
Checking Fixture — High-precision, GD and T-oriented inspection fixtures that allow rapid dimensional verification of stamped parts and welded assemblies, eliminating individual measurement variation.
Welding Jig — Custom welding fixtures designed for accurate, repeatable positioning during welding and assembly operations.

Welding Jig — Custom welding fixtures designed for accurate, repeatable positioning during welding and assembly operations.
The checking fixture capability deserves special attention. In automotive production, press dies and checking fixtures are needed as a set — the fixture verifies that every stamped part conforms to design dimensions before it moves to the next assembly stage. Dian Stamping designs and manufactures both, ensuring seamless fit and eliminating the coordination headache of sourcing tooling and inspection equipment from separate suppliers.
Quality Systems and Delivery Performance
Dian Stamping operates under a quality-management system certified to ISO 9001, and follows manufacturing and quality practices aligned with IATF 16949 standards for automotive production. Parts are inspected using in-line checks, 3D scanning (CMM), and checking fixtures to ensure they meet OEM specifications.
Typical delivery lead times are:
Steel stamping dies: 30–40 days
Casting stamping dies: approximately 70 days
Customization is available from 2D drawings, 3D data, or physical samples. Prototype services are also available for new product development programs. Free metal samples may be offered, with freight paid by the customer.
Why Global OEMs Choose Dian Stamping
