In the fast-paced world of automotive manufacturing, precision, reliability, and cost efficiency are non-negotiable. Every vehicle on the road relies on hundreds of stamped metal components — from body panels and structural reinforcements to brackets, heat shields, and seating systems. Behind every quality stamped part lies a precision-engineered die. Choosing the right automotive stamping dies manufacturer directly impacts your production quality, lead times, and bottom line.

LINHAI DIAN MOULD CO., LTD, operating under the brand DIAN STAMPING, has been serving the global automotive industry from Taizhou, Zhejiang, China since 2003. With over two decades of hands-on experience, the company has grown into a comprehensive manufacturing partner offering stamping dies, sheet metal parts, checking fixtures, welding jigs, and assembly services under one roof.

A Manufacturing Partner with Proven Scale

DIAN STAMPING operates a modern facility spanning approximately 50,000 m², including a dedicated die workshop of 4,000 m². The company employs around 110 skilled professionals, among them approximately 35 die designers and technicians. This infrastructure supports an impressive annual capacity of about 2,000 sets of medium and small stamping dies, with an annual die turnover of approximately RMB 50 million.

A planned 35,000 m² facility expansion featuring new press lines and advanced coating capabilities is already underway, reflecting the company's commitment to continuous growth and technological advancement.

Comprehensive Stamping Die Capabilities

At the core of DIAN STAMPING's offering is its expertise in progressive die stamping, transfer die stamping, and tandem die manufacturing. These die types cover a wide spectrum of automotive applications, including body-in-white components, door systems, seating systems, instrument panels, fuel-tank systems, exhaust systems, clutch systems, and chassis systems.

The company processes a variety of materials including multiphase steel, aluminum alloys, custom rolled and welded plate, and stainless steel — ensuring that diverse engineering requirements can be met without compromising on quality or delivery.

• Progressive Dies: High-efficiency multi-station tooling for complex, high-volume parts with tight tolerances
• Transfer Dies: Ideal for large and medium-sized components requiring sequential forming operations
• Tandem Dies: Flexible multi-step solutions for custom production runs
• Custom Tooling: Dies designed and built from 2D drawings, 3D data, or physical samples

Sheet Metal Parts & Custom Fabrication

Beyond die manufacturing, DIAN STAMPING is a reliable sheet metal parts supplier serving both automotive and household appliance industries. The company's sheet metal fabrication capabilities include laser cutting, bending, forming, welding, and surface coating. Products range from automotive body panels and chassis components to refrigerator brackets, hinges, evaporator panels, and structural supports.

Whether you need prototype sheet metal parts for validation or high-volume production runs, DIAN STAMPING provides end-to-end solutions from material selection through secondary operations such as deburring, hemming, flanging, and spot welding.

Precision Checking Fixtures for Quality Assurance

Quality control in automotive manufacturing demands reliable inspection tools. DIAN STAMPING designs and manufactures high-precision checking fixture solutions that enable fast, repeatable dimensional verification of stamped components and assemblies. These fixtures eliminate individual measurement variability and are essential for production sites where press dies and checking fixtures are used as a complementary set. The company's checking fixtures support GD&T-oriented inspection for automotive-quality standards.

Welding Jigs and Assembly Solutions

DIAN STAMPING also provides custom welding jig solutions for accurate, repeatable welding and assembly operations. These fixtures are designed to position components precisely during welding, ensuring consistent weld quality and dimensional accuracy across production runs. Combined with the company's welding and assembly services, customers benefit from a fully integrated manufacturing workflow.

Quality Systems and Certifications

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 reflected in its rigorous inspection processes, use of 3D scanning (CMM), and adherence to OEM specifications. Customers include globally recognized automotive brands such as KIA, BYD, Toyota, Honda, Suzuki, and Geely, with exports reaching more than 10 countries worldwide.

Why Global Automotive Buyers Choose DIAN STAMPING

As a direct factory rather than a trading company, DIAN STAMPING offers factory-direct pricing without intermediary markups. Typical delivery times are 30–40 days for steel stamping dies and approximately 70 days for casting stamping dies, subject to project requirements. The company provides free metal samples (with freight paid by the customer) and supports prototype services for new product development.

Customers can submit 2D drawings, 3D CAD data, or even physical samples for custom die design and manufacturing. With a dedicated team of 35 designers and technicians using industry-standard software, DIAN STAMPING ensures that every tool is engineered for optimal performance, durability, and cost-efficiency.
