In the fast-paced world of automotive manufacturing, the quality of every stamped component directly impacts vehicle safety, performance, and production efficiency. Whether you are an OEM developing a new model or a Tier-1 supplier scaling up production, finding a reliable partner with deep expertise in automotive stamping dies and precision sheet metal fabrication is critical. LINHAI DIAN MOULD CO., LTD (Dian Stamping), established in 2003 in Zhejiang, China, has spent over two decades perfecting the art of die-making and metal stamping — serving globally recognized brands including KIA, BYD, Toyota, Honda, Suzuki, and Geely.
Who We Are: A Factory, Not a Trading Company
Dian Stamping positions itself as a direct manufacturing partner, not a middleman. The company operates a modern facility covering approximately 50,000 m², with a dedicated die workshop of around 4,000 m². With over 110 employees — including approximately 35 skilled die designers and technicians — the company delivers end-to-end solutions from tool design and die manufacturing to high-volume stamping, welding, and assembly. This vertical integration ensures consistent quality control, shorter lead times, and competitive factory-direct pricing.
Manufacturing Capabilities That Set Us Apart
As one of the leading stamping die manufacturers in China, Dian Stamping has built an annual production capacity of approximately 2,000 sets of medium and small stamping dies, with an annual die turnover of around RMB 50 million. The company's die portfolio includes progressive dies, transfer dies, and tandem/multi-station dies, capable of handling a wide range of materials — from multiphase steel and aluminum to custom rolled and welded plate and stainless steel.
A planned 35,000 m² facility expansion, featuring new press lines and coating lines, will further enhance capacity and capability. Typical delivery times are 30–40 days for steel stamping dies and approximately 70 days for casting stamping dies, subject to project complexity.
Comprehensive Product & Service Portfolio
Dian Stamping offers four core product categories that cover the full spectrum of automotive metal forming needs:
Quality Assurance: Built on Industry Standards
Dian Stamping operates under an ISO 9001 quality management system and follows IATF 16949-oriented automotive manufacturing practices. The company's commitment to quality is further reflected in its use of in-line inspections, 3D coordinate measuring machines (CMM), and strain analysis to ensure every die and stamped part meets OEM specifications. Whether you need a checking fixture for production validation or a complete die package for a new vehicle program, Dian Stamping delivers with documented quality assurance.
Customization and Prototyping Services
Every project starts with understanding the customer's unique requirements. Dian Stamping accepts 2D drawings, 3D data, or physical samples as input for custom tooling design. Prototype services are available for new product development, allowing customers to validate designs before committing to full-scale production. Free metal samples can be provided upon request (freight paid by the customer), giving buyers confidence in material quality and surface finish.

The company's customer roster — KIA, BYD, Toyota, Honda, Suzuki, and Geely — speaks to its reliability and technical competence. With exports to more than 10 countries, Dian Stamping has proven its ability to meet international quality standards, delivery schedules, and communication expectations. As a factory-direct sheet metal parts manufacturer, the company offers competitive pricing without compromising on precision or service.
