In the automotive industry, the difference between a part that fits perfectly and one that fails on the line often comes down to the quality of the tooling behind it. Every body panel, structural reinforcement, and chassis component demands precision dies that can hold tight tolerances through thousands of production cycles. That is why global OEMs and Tier-1 suppliers turn to experienced stamping die manufacturers who combine engineering expertise with manufacturing scale.

DIAN STAMPING, operating under LINHAI DIAN MOULD CO., LTD., has been delivering exactly that level of reliability since 2003. Based in Huangyan, Taizhou, Zhejiang Province 鈥?one of China's established manufacturing hubs 鈥?the company has grown into a comprehensive one-stop supplier of automotive stamping dies, sheet metal parts, checking fixtures, and welding jigs for customers around the world.

DIAN STAMPING's manufacturing footprint is substantial. The company operates a modern facility covering approximately 50,000 m虏, which includes a dedicated die workshop of 4,000 m虏. With a skilled workforce of around 110 employees 鈥?including approximately 35 die designers and technicians 鈥?the company achieves an annual production capacity of roughly 2,000 sets of medium and small stamping dies, supported by an annual die turnover of approximately RMB 50 million.

A planned 35,000 m虏 expansion featuring new press and coating lines will further extend DIAN STAMPING's capabilities, reinforcing its commitment to continuous investment in modern manufacturing infrastructure.

DIAN STAMPING offers a full spectrum of manufacturing services under one roof, eliminating the complexity of managing multiple suppliers:

Stamping Dies 鈥?A full range of progressive dies, transfer dies, and tandem/multi-station dies designed for complex automotive and industrial parts, from body-in-white panels to structural reinforcements.

Sheet Metal Parts 鈥?Custom stamping and fabrication for automotive body parts, household appliance components, and industrial assemblies, including welding and assembly services.

Checking Fixtures 鈥?High-precision, GD&T-oriented inspection fixtures that enable fast, repeatable dimensional verification of stamped components and welded assemblies.

Welding Jigs 鈥?Custom-designed fixtures for accurate, repeatable positioning during welding and assembly operations, supporting consistent quality in production.

DIAN STAMPING processes a wide range of materials including multiphase steel, aluminum alloys, custom rolled and welded plate, and stainless steel. The engineering team works from customer-supplied 2D drawings, 3D data, or physical samples, offering prototype services before full-scale production. This design-to-delivery approach ensures that every sheet metal parts supplier experience is streamlined from quotation to final shipment.

DIAN STAMPING operates under a quality management system aligned with ISO 9001 standards and follows IATF 16949-oriented automotive manufacturing practices. Advanced inspection methods 鈥?including CMM (coordinate measuring machines) and 3D scanning 鈥?are applied throughout the production process to ensure every die and part meets strict OEM dimensional specifications.

Over two decades of consistent delivery have earned DIAN STAMPING the trust of major automotive brands. The company's customer roster includes KIA, BYD, Toyota, Honda, Suzuki, and Geely. With exports to more than 10 countries, DIAN STAMPING has demonstrated its ability to meet the quality, lead-time, and cost requirements of international automotive supply chains.

Factory-direct pricing 鈥?As a direct manufacturer rather than a trading company, DIAN STAMPING offers competitive pricing without intermediary markups.

Fast lead times 鈥?Typical delivery is 30-40 days for steel stamping dies and approximately 70 days for casting stamping dies, subject to project scope.

One-stop service 鈥?From die design and tryout to stamping, welding, and assembly, all under one roof.

Customization 鈥?Parts can be manufactured from 2D drawings, 3D CAD data, or physical samples, with prototype services available.

Free metal samples 鈥?Prospective customers can request free samples (freight paid by the customer) to evaluate quality before committing to production.
