Two Decades of Automotive Tooling Excellence

Founded in 2003 in Huangyan, Taizhou, Zhejiang Province — a region renowned for its mold-making heritage — Dian Stamping has grown from a small tooling workshop into a modern manufacturing facility spanning approximately 50,000 m². With a dedicated die workshop of 4,000 m² and a team of around 110 employees, including 35 experienced die designers and technicians, the company delivers an annual capacity of approximately 2,000 sets of medium and small stamping dies.

The company's annual die turnover of approximately RMB 50 million reflects its established position in the automotive supply chain. A new 35,000 m² facility currently under development, featuring advanced press and coating lines, further underscores Dian Stamping's commitment to continuous improvement and capacity expansion.

Comprehensive Die and Stamping Capabilities

As one of the trusted stamping die manufacturers in China, Dian Stamping offers a full spectrum of tooling solutions tailored to the automotive industry's exacting standards. The company's core capabilities include:

• Progressive Dies — High-efficiency multi-station tooling for high-volume production of complex parts, minimizing handling and maximizing throughput.
• Transfer Dies — Ideal for large and medium-sized panels requiring multiple forming operations, with precise part transfer between stations.
• Tandem and Multi-Station Dies — Flexible solutions for a wide range of part geometries, from body-in-white components to chassis and powertrain parts.

The company processes a diverse range of materials including multiphase steel, aluminum alloys, custom rolled and welded plate, and stainless steel, making it a versatile partner for projects of varying complexity.

Beyond Dies: A One-Stop Manufacturing Partner

What sets Dian Stamping apart from many tooling suppliers is its ability to deliver end-to-end manufacturing services. Beyond precision progressive die stamping, the company offers:

• Stamped Sheet Metal Parts — Production-ready automotive and household appliance stampings, from prototypes to high-volume runs, with options for laser cutting, bending, welding, and surface treatment.
• Checking Fixtures — High-precision, GD&T-oriented inspection fixtures that enable fast and accurate dimensional verification of stamped components and assemblies, eliminating measurement subjectivity.
• Welding Jigs and Assemblies — Custom positioning and welding fixtures designed for repeatable, accurate production, along with welded sub-assemblies ready for direct integration into customers' production lines.

This vertically integrated approach means that Dian Stamping can manage the entire production chain — from die design and manufacturing to part stamping, inspection, and assembly — ensuring consistent quality, shorter lead times, and simplified supply chain management for its customers.

Proven Track Record with Global OEMs

Experience matters in automotive tooling. Dian Stamping's customer roster includes globally recognized brands such as KIA, BYD, Toyota, Honda, Suzuki, and Geely. The company exports to more than 10 countries, serving not only automotive OEMs but also Tier 1 suppliers and industrial manufacturers needing custom tooling, high-volume stamped parts, and inspection fixtures.

The company's quality management system is ISO 9001 certified, with manufacturing practices aligned to IATF 16949-oriented automotive standards. This commitment to quality is reinforced by rigorous in-process inspections, dimensional validation, and functional testing at every stage of die development and part production.

Factory-Direct Pricing and Flexible Customization

As a factory rather than a trading company, Dian Stamping offers direct pricing without intermediary markups. Customers can submit requirements in the form of 2D drawings, 3D data, or physical samples, and the engineering team will develop custom solutions tailored to specific production needs. Prototype services are available for validation before mass production.

Typical delivery times are 30–40 days for steel stamping dies and approximately 70 days for casting stamping dies, depending on project complexity. Free metal samples can be provided upon request, with the customer covering freight costs.

Application Across Key Automotive Systems

Dian Stamping's tooling and parts are used across a wide range of automotive systems, demonstrating the company's engineering breadth:

• Body-in-White — Side frames, A-pillar panels, spare tire wells, and structural reinforcements
• Door Systems — Hinge reinforcement plates, guide rails, water-cut panels, and inner/outer panels
• Seating Systems — Seat basins, support beams, B-pillar liners, and chassis seats
• Instrument Panels — Dashboard support structures and cross-car beams
• Exhaust and Fuel Systems — Heat shields, shields, and mounting brackets
• Chassis and Powertrain — Control arms, swing arms, and battery cases for electric vehicles
