In today's fiercely competitive automotive landscape, sourcing high-quality stamped components from a reliable sheet metal parts supplier is no longer optional — it is a strategic necessity. Whether you are an OEM launching a new vehicle platform or a Tier-1 supplier scaling production, the quality of your stamping tooling and metal parts directly impacts vehicle safety, assembly precision, and manufacturing cost. With over two decades of industry experience, LINHAI DIAN MOULD CO., LTD (DA Stamping) has emerged as a trusted manufacturing partner for global automotive brands, delivering end-to-end solutions from die design to high-volume production.

A Legacy of Precision Since 2003

Founded in 2003 and headquartered in Huangyan, Taizhou, Zhejiang Province, DA Stamping has grown from a specialized tooling workshop into a comprehensive manufacturing facility spanning approximately 50,000 m². The company employs over 110 skilled professionals, including around 35 die designers and technicians, and maintains an annual production capacity of approximately 2,000 sets of medium and small stamping dies. This scale allows DA Stamping to serve customers across more than 10 countries, including renowned OEMs such as KIA, BYD, Toyota, Honda, Suzuki, and Geely.

Unlike many trading companies that merely broker manufacturing services, DA Stamping operates as a true factory — giving clients direct access to in-house engineering, production, and quality control. This vertical integration translates into faster turnaround times, better cost control, and consistent quality across every project.

Comprehensive Capabilities Under One Roof

What sets DA Stamping apart from other stamping die manufacturers is the breadth of its in-house capabilities. The company offers a fully integrated service chain that covers the entire product lifecycle:

• Stamping Dies: Precision progressive dies, transfer dies, and tandem/multi-station dies for large and medium-sized complex parts. The dedicated die workshop spans approximately 4,000 m² and is equipped to handle advanced materials including multiphase steel, aluminum, custom rolled and welded plate, and stainless steel.
• Sheet Metal Parts: High-volume production of automotive stamped components — from body-in-white panels and door systems to seating structures, instrument panel supports, fuel-tank components, and chassis parts.
• Checking Fixtures: High-precision, GD&T-oriented inspection fixtures that ensure every stamped component meets stringent dimensional requirements before assembly.
• Welding Jigs & Assembly: Custom welding fixtures, welding parts, and assembly solutions that enable accurate, repeatable production and reduce downstream rework.

This one-stop approach eliminates the inefficiencies of managing multiple suppliers and ensures seamless coordination between tooling design, part production, and quality inspection.

Advanced Tooling for Demanding Applications

When it comes to automotive stamping dies, precision and durability are non-negotiable. DA Stamping specializes in designing and manufacturing tooling that delivers consistent performance across millions of cycles. The company's die engineering team leverages advanced CAD/CAM software and simulation tools to optimize die designs before cutting steel, reducing tryout time and ensuring first-pass quality.

Key application areas served by DA Stamping's tooling include:

• Body-in-White (BIW): Side frames, rear outer panels, A-pillar reinforcements, spare tire wells, and panoramic sunroof support panels.
• Door Systems: Hinge reinforcement plates, water-cut reinforcement panels, and door inner/outer panels.
• Seating Systems: Seat basins, support beams, B-pillar liners, and chassis seats.
• Exhaust & Fuel Systems: Heat shields, flow channels, and fuel-tank components.

The company's reported annual die turnover of approximately RMB 50 million reflects both the scale and the trust that major automotive brands place in its tooling capabilities.

Quality Management You Can Rely On

Quality assurance is embedded in every stage of DA Stamping's manufacturing process. The company operates under an ISO 9001-certified quality management system and follows IATF 16949-oriented automotive manufacturing practices. This commitment to quality is reinforced by:

• Rigorous Inspection Protocols: In-line dimensional checks, CMM (coordinate measuring machine) verification, and checking fixture validation for every production batch.
• Material Traceability: Full documentation of material grades, heat numbers, and coating specifications to ensure compliance with OEM requirements.
• Continuous Improvement: Statistical process control (SPC) and root-cause analysis to drive ongoing quality gains and reduce variation.

For customers who require validation before mass production, DA Stamping offers prototype services and free metal samples (with freight paid by the customer), allowing you to evaluate part quality and fit before committing to full-scale production.

Customization and Flexible Delivery

Every automotive program is unique, and DA Stamping's engineering team is equipped to handle custom projects from virtually any starting point — whether you provide 2D drawings, 3D CAD data, or physical samples. The company's design-to-production workflow is streamlined to minimize lead times while maintaining the highest quality standards.

Typical delivery timelines are:

• Steel stamping dies: 30–40 days from design approval
• Casting stamping dies: Approximately 70 days, subject to project complexity

These timelines are supported by a dedicated project management team that provides regular progress updates and facilitates smooth communication between engineering, production, and logistics.

Global Reach, Local Expertise

With exports to more than 10 countries and long-term supply relationships with major OEMs, DA Stamping has developed a deep understanding of international quality standards, packaging requirements, and logistics. The company's location in Taizhou, Zhejiang — one of China's most established manufacturing hubs — provides access to a mature supply chain ecosystem and efficient port connections for global shipping.

Whether you need progressive die tooling for a high-volume BIW program, custom sheet metal parts for an EV battery enclosure, or precision checking fixtures for quality assurance, DA Stamping combines factory-direct pricing with the engineering capability to deliver results that meet — and often exceed — your expectations.
