Two Decades of Precision Tooling Experience Delivering Cost-Effective Stamping Solutions for Global Automotive OEMs
When sourcing stamping die manufacturers for your next automotive program, the decision goes far beyond comparing price quotes. It is about evaluating real manufacturing capability, engineering depth, quality systems, and the proven ability to deliver complex tooling projects on time. For over two decades, DIAN STAMPING — the manufacturing division of Linhai Dian Mould Co., Ltd — has served as a trusted partner to global automotive OEMs and Tier 1 suppliers, offering a comprehensive one-stop solution for stamping dies, sheet metal parts, checking fixtures, and welding jigs.
Company Overview: 20+ Years of Industry Leadership
Established in 2003 in Huangyan, Taizhou, Zhejiang Province — a region renowned for its advanced mould and die manufacturing ecosystem — DIAN STAMPING has grown from a specialized tooling workshop into a full-scale manufacturing facility. The company employs approximately 110 people, including 35 experienced die designers and technicians, and operates a modern 50,000 m² facility with a dedicated 4,000 m² die workshop. A new 35,000 m² facility featuring advanced press and coating lines is currently in development, reflecting the company’s commitment to continuous capacity expansion.
DIAN STAMPING’s customer roster includes globally recognized automotive brands such as KIA, BYD, Toyota, Honda, Suzuki, and Geely, with exports reaching more than 10 countries worldwide. This track record demonstrates the company’s ability to meet the rigorous quality and delivery standards demanded by the global automotive industry.
Manufacturing Scale and Core Capabilities
As one of the leading automotive stamping dies manufacturers in China, DIAN STAMPING has built a robust production system that covers the entire tooling lifecycle — from design and CNC machining to assembly, tryout, and quality inspection.
The company’s die-making capabilities cover progressive dies, transfer dies, and tandem/multi-station dies. DIAN STAMPING processes a wide range of materials including multiphase steel, aluminum alloys, custom rolled and welded plate, and stainless steel — making it a versatile partner for diverse automotive applications.
Comprehensive Product Range
Unlike many tooling suppliers that specialize in only one area, DIAN STAMPING offers four integrated product categories, enabling customers to consolidate their supply chain and reduce program management complexity.
Precision stamping tooling including progressive, transfer, and tandem dies for large and medium-sized complex automotive parts. Applications span body-in-white, door systems, seating systems, instrument panels, fuel-tank systems, exhaust systems, clutch systems, and chassis systems.
High-volume production of automotive and household-appliance stampings, custom metal parts, and welding assemblies. The company supports prototyping through mass production with materials ranging from high-strength steel to aluminum and stainless steel.
High-precision, GD&T-oriented inspection fixtures designed to verify dimensional accuracy of stamped components and welded assemblies. A checking fixture and press die are always required as a set in production environments, and DIAN STAMPING supplies both, eliminating individual measurement variations.
Custom welding fixtures and supporting services for accurate, repeatable production and assembly. These jigs ensure precise positioning during welding operations, reducing rework and improving throughput in automotive assembly lines.
Quality Assurance and Customization
DIAN STAMPING operates under an ISO 9001-certified quality management system, with manufacturing practices aligned to IATF 16949-oriented automotive standards. The company positions itself as a direct factory — not a trading company — which means customers benefit from factory-direct pricing, direct engineering communication, and faster response times.
Customization is a core strength. Customers can submit parts for quotation via 2D drawings, 3D data, or physical samples. Prototype services are available for new program development, and free metal samples can be provided (with freight paid by the customer). Typical lead times are 30–40 days for steel stamping dies and approximately 70 days for casting stamping dies, subject to project complexity and requirements.
