When sourcing tooling for automotive production, the choice of partner directly impacts your project's cost, quality, and timeline. For over two decades, LINHAI DIAN MOULD CO., LTD (Dian Stamping) has served as a trusted stamping die manufacturers partner to global OEMs and Tier 1 suppliers, delivering precision-engineered tooling and stamped components from its modern facility in Zhejiang, China.

A Legacy of Precision in Automotive Stamping

Established in 2003, Dian Stamping has grown into a comprehensive manufacturing hub spanning approximately 50,000 m², with a dedicated die workshop of 4,000 m². The company's annual capacity reaches approximately 2,000 sets of medium and small stamping dies, with a reported annual die turnover of around RMB 50 million. This scale, combined with a team of around 110 employees including 35 skilled die designers and technicians, positions Dian Stamping as a capable and reliable production partner.

The company's client list speaks to its quality and reliability: KIA, BYD, Toyota, Honda, Suzuki, and Geely are among the automotive names that trust Dian Stamping for their tooling and stamped parts. With exports reaching more than 10 countries, the company has proven its ability to meet international standards across diverse markets.

Comprehensive Automotive Stamping Dies and Services

Dian Stamping offers a full spectrum of tooling solutions under one roof, eliminating the need for multiple suppliers and reducing coordination overhead for buyers.

The company designs and manufactures progressive dies, transfer dies, and tandem/multi-station dies for large and medium-sized complex automotive parts. These precision tools serve a wide range of vehicle systems including:

• Body-in-white (BIW) components — panels, frames, and structural reinforcements
• Door systems — hinge reinforcements, inner and outer panels, and guides
• Seating systems — seat basins, support beams, brackets, and chassis seats
• Instrument panels and dashboard components
• Fuel-tank, exhaust, and clutch system components

Beyond tooling, Dian Stamping produces high-quality stamped sheet metal parts for both automotive and household appliance industries. The company handles custom fabrication from 2D drawings, 3D data, or physical samples, and supports prototype development through to high-volume production. Material capabilities include multiphase steel, aluminum, custom rolled and welded plate, and stainless steel.

Quality assurance is integral to the stamping process. Dian Stamping provides high-precision checking fixture solutions designed for GD&T-oriented inspection of stamped components and welded assemblies. These fixtures enable rapid, repeatable dimensional verification — eliminating individual measurement variability and ensuring every part meets specification before shipment.

Custom welding jigs and fixtures support accurate, repeatable production and assembly. Combined with the company's welding parts and assembly services, Dian Stamping offers a true one-stop solution for automotive manufacturers seeking integrated tooling and production support.

Quality Systems and Manufacturing Standards

Dian Stamping operates under an ISO 9001 quality management system, with manufacturing practices aligned to IATF 16949-oriented automotive standards. The planned addition of a new 35,000 m² facility featuring advanced press lines and coating capabilities reflects the company's ongoing investment in capacity and technology.

Factory-Direct Pricing Without the Middleman

Unlike trading companies or brokers, Dian Stamping is a factory-direct manufacturer. This means buyers benefit from competitive pricing, direct communication with the engineering team, faster response times, and full visibility into the production process. Whether you need a single prototype checking fixture or a high-volume run of stamping dies, the factory model ensures cost efficiency and quality control from raw material to finished product.
