The global automotive industry demands precision, consistency, and cost-efficiency at every stage of production. From body-in-white panels to seating system components, the quality of stamped parts directly affects vehicle safety, assembly fit, and manufacturing throughput. Choosing the right manufacturing partner for automotive stamping dies and fabricated metal components is therefore one of the most critical decisions OEMs and Tier-1 suppliers make.
Linhai Dian Mould Co., Ltd (Dian Stamping), established in 2003 in Taizhou, Zhejiang Province, has built a reputation as a reliable, one-stop manufacturing partner for the global automotive supply chain. With a 50,000 m² modern facility, approximately 110 employees including 35 die designers and technicians, and an annual die output of about 2,000 sets, Dian Stamping offers the scale, expertise, and quality systems that automotive buyers demand.
Comprehensive Stamping Die Capabilities
At the core of Dian Stamping's offering is its full-spectrum die-making capability. The company designs and builds progressive dies, transfer dies, and tandem (multi-station) dies for medium and large complex parts. These tools are used across a wide range of automotive applications including door systems, instrument panels, fuel-tank systems, exhaust systems, clutch systems, and chassis systems.
The die workshop spans approximately 4,000 m² and is equipped to handle tool steel, carbide, and high-speed steel tooling. Materials processed include multiphase steel (HSS/AHSS), aluminum alloys, custom-rolled and welded plate, and stainless steel. Whether the project calls for a new die set for a vehicle program ｕｐｄａｔｅ or a fully custom tool for a unique stamping geometry, Dian Stamping's engineering team delivers using CAD/CAM software and in-house tryout capabilities.
Annual die turnover is approximately RMB 50 million, reflecting the company's established position in the die-making market. A planned 35,000 m² expansion featuring new press and coating lines will further increase capacity and capability.
Precision Sheet Metal Parts for Automotive and Appliance Industries
Beyond tooling, Dian Stamping is a full-service producer of custom sheet metal parts for both automotive and household appliance applications. The company's sheet metal stamping capabilities cover high-volume production runs of brackets, panels, hinges, reinforcement plates, heat shields, seat components, and structural assemblies.
Dian Stamping works with materials including cold-rolled steel, galvanized steel, stainless steel, and aluminum. Secondary operations such as laser cutting, bending, welding, deburring, and powder coating are all available in-house, enabling the delivery of finished, assembly-ready parts. Customers can submit requirements from 2D drawings, 3D CAD data, or physical samples for prototyping and mass production.
Key capabilities: Progressive and transfer stamping, deep drawing, custom tool and die design, high-volume production, prototype services, and end-to-end solutions from design to delivery.
Quality Assurance with Checking Fixtures
In automotive stamping, quality control is not optional — it is a prerequisite. Dian Stamping provides high-precision checking fixture solutions that enable fast, repeatable inspection of stamped parts and welded assemblies. A checking fixture allows operators to verify whether a manufactured workpiece conforms to specified dimensions simply by placing it in the fixture, eliminating individual measurement variation and speeding up production-line quality checks.
The company's checking fixtures are designed and built in-house, aligned with GD&T (Geometric Dimensioning and Tolerancing) standards. As the company's FAQ states, press dies and checking fixtures are always required as a set — a philosophy that ensures every tooled part has a corresponding inspection solution. This integrated approach reduces downstream quality surprises and helps OEMs maintain consistent part quality across high-volume production runs.
Welding Jigs and Assembly Services
Dian Stamping also offers custom welding jigs and supporting services for accurate, repeatable production and assembly. Welding jigs ensure that stamped components are positioned correctly during welding, maintaining dimensional accuracy and reducing rework. The company produces welded assemblies and finished parts ready for integration into vehicle body structures, seating systems, and exhaust systems.
Proven Track Record with Global OEMs
Dian Stamping counts major automotive brands among its customers, including KIA, BYD, Toyota, Honda, Suzuki, and Geely. The company exports to more than 10 countries, serving both OEMs and Tier suppliers who require reliable tooling, high-volume stamped parts, and inspection fixtures.
As a factory-direct manufacturer rather than a trading company, Dian Stamping offers competitive pricing without sacrificing quality. The company operates under ISO 9001 quality management and follows IATF 16949-oriented automotive manufacturing practices.
Factory advantages: Direct factory pricing, no middlemen. Typical delivery is 30-40 days for steel stamping dies and approximately 70 days for casting stamping dies, subject to project requirements. Free metal samples are available with freight paid by the customer.
