Sourcing high-quality stamped metal components from overseas suppliers has long been a balancing act for automotive OEMs and Tier-1 suppliers. You need tooling precision, production scalability, consistent quality, and competitive pricing — all while navigating complex supply chains. DIAN STAMPING, a China-based manufacturer with over 20 years of industry experience, has built its reputation on eliminating these trade-offs by offering fully integrated, end-to-end manufacturing under one roof.

From designing and building automotive stamping dies to producing high-volume sheet metal components and assembly-ready parts, DIAN STAMPING delivers a seamless production pipeline that reduces lead times, lowers total cost, and ensures consistent quality across every project.

A Manufacturing Partner Built for Scale

Established in 2003 and headquartered in Linhai, Taizhou, Zhejiang Province, DIAN STAMPING (LINHAI DIAN MOULD CO., LTD) operates a modern 50,000 m² facility that houses die-making, stamping, welding, and assembly operations. The company's annual capacity of approximately 2,000 sets of medium and small stamping dies and a dedicated die workshop of 4,000 m² reflect a production infrastructure designed for both high-mix and high-volume demands.

With approximately 35 dedicated die designers and technicians on staff, DIAN STAMPING brings deep engineering expertise to every project, supporting customers from concept and prototype through full-scale production. The company is also investing in a new 35,000 m² facility featuring advanced press and coating lines, further expanding its capacity to serve global automotive customers.

Comprehensive Capabilities Across the Manufacturing Spectrum

What sets DIAN STAMPING apart is its ability to manage the entire manufacturing lifecycle — from tooling design to finished assembly — within a single, integrated facility. This vertical integration eliminates the handoffs, communication gaps, and quality inconsistencies that commonly arise when working with multiple suppliers.

Stamping Dies — Precision Tooling for Complex Parts

DIAN STAMPING designs and manufactures a full range of stamping tooling, including progressive dies, transfer dies, and tandem/multi-station dies. These are used to produce complex automotive components such as body-in-white panels, door system parts, seating system components, instrument panel structures, and chassis parts. The company works with a variety of materials including multiphase steel, aluminum alloys, custom rolled and welded plate, and stainless steel, ensuring the right material match for each application.

Sheet Metal Parts — High-Volume Production with Consistent Quality

As a reliable sheet metal parts manufacturer, DIAN STAMPING produces stamped components for automotive body structures, seating systems, exhaust systems, clutch systems, and household appliance applications. The company's sheet metal fabrication capabilities include progressive die stamping, deep drawing, metal laser cutting, bending, and welding assembly — all supported by in-house quality control processes.

For customers seeking precision sheet metal fabrication parts, DIAN STAMPING offers end-to-end solutions from prototyping to mass production, with material options spanning stainless steel, aluminum, cold-rolled steel, and galvanized steel. Typical delivery for steel stamping dies ranges from 30 to 40 days, with casting die lead times around 70 days, subject to project scope.

Checking Fixtures & Welding Jigs — Accuracy at Every Stage

Quality assurance is built into the production process, not checked at the end. DIAN STAMPING manufactures high-precision checking fixtures and welding jigs that enable fast, accurate dimensional verification and repeatable welding assembly. These fixtures are designed in accordance with GD&T principles and are essential for eliminating measurement variability in high-volume production environments.
