In the competitive world of automotive manufacturing, the quality of your stamped components directly impacts vehicle safety, structural integrity, and production efficiency. Yet many OEMs and Tier-1 suppliers find themselves juggling multiple vendors for die design, stamping production, inspection fixtures, and welding assembly — a fragmented approach that introduces communication gaps, quality inconsistencies, and extended lead times. DA Stamping (LinHai Dian Mould Co., Ltd.) offers a fundamentally different approach: a vertically integrated manufacturing partner with over two decades of experience delivering end-to-end solutions under one roof.

A Legacy of Precision Since 2003

Founded in 2003 in Huangyan, Taizhou, Zhejiang Province — a region renowned for its mould and die manufacturing expertise — DA Stamping has grown from a specialized tooling shop into a comprehensive manufacturing enterprise. The company operates a modern facility spanning approximately 50,000 m², with a dedicated die workshop of 4,000 m² and a team of around 110 skilled professionals, including approximately 35 die designers and technicians. A newly planned 35,000 m² facility featuring advanced press lines and coating lines is set to further expand production capacity.

With an annual capacity of approximately 2,000 sets of medium and small stamping dies and an annual die turnover of roughly RMB 50 million, DA Stamping has established itself as a reliable partner for global automotive brands including KIA, BYD, Toyota, Honda, Suzuki, and Geely, exporting to more than 10 countries worldwide.

Comprehensive Stamping Die Capabilities

At the heart of DA Stamping's offering is its expertise in precision automotive stamping dies. The company designs and manufactures progressive dies, transfer dies, and tandem/multi-station dies for a wide range of complex automotive parts. Whether it is body-in-white components, door system panels, seating system structures, or chassis parts, DA Stamping's tooling engineers leverage advanced CAD/CAM software to deliver dies that meet the tightest tolerance requirements.

The company's material processing capabilities are equally impressive. DA Stamping works with multiphase steel (including advanced high-strength steels), aluminum alloys, custom rolled and welded plate, and stainless steel — enabling it to support the lightweighting and performance demands of modern vehicle platforms.

Beyond Dies: A One-Stop Manufacturing Ecosystem

What truly distinguishes DA Stamping from conventional stamping die manufacturers is its ability to provide a complete manufacturing ecosystem. The company does not stop at delivering dies — it also produces stamped sheet metal parts, precision checking fixtures, welding jigs, welding assemblies, and finished assembly components.

This vertical integration delivers tangible benefits for customers:

• Single-Point Accountability: One team manages the entire production chain from die design to final assembly, eliminating coordination overhead between separate suppliers.
• Faster Time-to-Market: In-house die tryout and production validation mean shorter iteration cycles and faster ramp-up for new vehicle programs.
• Cost Efficiency: Factory-direct pricing with no intermediary markups, backed by a 30–40 day typical delivery for steel stamping dies and approximately 70 days for casting dies.
• Consistent Quality: Unified quality standards across tooling, stamping, and assembly processes ensure that the final part matches the original design intent.

Precision Quality Assurance with Checking Fixtures

Quality control in stamping production is only as reliable as the inspection tools used to verify it. DA Stamping designs and manufactures high-precision checking fixture solutions that enable rapid, repeatable dimensional verification of stamped components and welded assemblies. Using GD&T-oriented fixture design, these checking fixtures allow operators to inspect large volumes of parts quickly and consistently — eliminating the individual measurement variation that can occur with manual tools like vernier calipers or micrometers.

As the company's engineering team emphasizes, press dies and checking fixtures are always required as a set. By offering both under one roof, DA Stamping ensures that every die it builds is paired with a corresponding inspection fixture that matches the exact part geometry — a level of integration that standalone fixture suppliers cannot match.

Welding Jigs and Assembly Solutions

Beyond stamping and inspection, DA Stamping provides custom welding jigs and fixture systems that support accurate, repeatable welding and assembly operations. From spot welding jigs to chassis welding fixtures and rotating welding jigs, the company's welding jig solutions are designed to integrate seamlessly with its stamped parts, ensuring dimensional accuracy in the final welded assembly.

This capability is particularly valuable for automotive body-in-white and structural sub-assembly applications, where weld accuracy directly affects crash performance and vehicle fit-and-finish.

Quality Certifications and Industry Standards

DA Stamping operates under a quality management system certified to ISO 9001, with manufacturing practices aligned to IATF 16949 automotive standards. The company's commitment to quality is reflected in its rigorous in-process inspections, use of coordinate measuring machines (CMM) for dimensional validation, and adherence to OEM-specific quality requirements.

Customization is available from 2D drawings, 3D CAD data, or physical samples, and prototype services are offered to support new product development and design validation before mass production.

Application Areas Across the Vehicle

DA Stamping's products and services span the full spectrum of automotive applications:

• Body-in-White: Side frames, rear outer panels, A-pillar reinforcements, spare tire wells, and structural stampings
• Door Systems: Hinge reinforcement plates, water-cut reinforcement panels, and door inner/outer assemblies
• Seating Systems: Seat basins, support beams, B-pillar liners, and chassis seats
• Instrument Panels: Cross-car beams and support brackets
• Exhaust Systems: Heat shields and mounting brackets
• Chassis Systems: Swing arms, control arms, and suspension components
