In the automotive industry, the quality of a stamped component begins with the die that shapes it. Whether you are producing body-in-white panels, chassis reinforcements, or seat-system brackets, the performance of your automotive stamping dies directly determines dimensional accuracy, production throughput, and overall part cost. Choosing the right stamping die manufacturers is therefore one of the most strategic decisions an OEM or Tier-1 supplier can make.

DIAN STAMPING (LINHAI DIAN MOULD CO., LTD), headquartered in Taizhou, Zhejiang, China, has been delivering precision stamping tooling and stamped components since 2003. With over 20 years of industry experience, a 50,000 m² production facility, and a team of approximately 35 die designers and technicians, the company has earned the trust of global automotive brands including KIA, BYD, Toyota, Honda, Suzuki, and Geely, exporting to more than 10 countries worldwide.

Comprehensive Die Manufacturing Capabilities

DIAN STAMPING specializes in three main types of stamping dies, each suited to different production requirements:

• Progressive Dies — Ideal for high-volume production of complex parts requiring multiple operations (piercing, forming, drawing, trimming) in a single press stroke. These dies deliver consistent quality and rapid cycle times.
• Transfer Dies — Designed for large and medium-sized parts where the workpiece is transferred between stations by a transfer system. Perfect for deep-drawn and geometrically complex components.
• Tandem / Multi-Station Dies — A cost-effective solution for medium-volume runs, where individual dies are arranged in a press line with automated part transfer between stations.

The company's annual die output exceeds 2,000 sets of medium and small stamping dies, with an annual die turnover of approximately RMB 50 million. Every die is engineered using advanced CAD/CAM software, precision-machined on modern CNC equipment, and rigorously tested before delivery.

Beyond Dies: A True One-Stop Manufacturing Partner

What sets DIAN STAMPING apart from traditional stamping die manufacturers is its vertically integrated production model. Unlike many suppliers who outsource secondary operations, DIAN STAMPING handles every stage in-house — from die design and development to sheet metal stamping, welding, powder coating, electrophoresis, and finished product assembly. This full-industry-chain approach eliminates coordination delays, reduces costs, and ensures consistent quality at every step.

The company's affiliated entities — Linhai Diyao New Technology Co., Ltd. and Taizhou Elay International Trade Co., Ltd. — further strengthen its supply chain and export capabilities.

Precision Inspection with Checking Fixtures

Quality assurance is only as reliable as the inspection tools used. DIAN STAMPING designs and manufactures custom checking fixture solutions that verify whether stamped components meet dimensional specifications. A checking fixture allows operators to inspect large volumes of parts rapidly and consistently — simply by locating the workpiece on the fixture. This is especially critical for complex geometries that cannot be measured efficiently with calipers or micrometers. Press dies and checking fixtures go hand in hand, and DIAN STAMPING supplies both as a matched set, eliminating individual measurement variation and ensuring every part meets GD&T requirements.

Welding Jigs for Accurate Assembly

Welding operations demand precise positioning and repeatable clamping. DIAN STAMPING provides custom welding jig solutions — including modular tooling systems, spot welding fixtures, and assembly jigs — designed to enhance accuracy and throughput in welding processes. These fixtures are engineered to hold components in exact alignment, reduce rework, and accelerate production cycles for automotive sub-assemblies.

Application Coverage Across Vehicle Systems

DIAN STAMPING's tooling and stamped components are used across a broad spectrum of automotive systems:

The company also serves the household appliance industry, producing stamped components for refrigerators, washing machines, and ovens — demonstrating its versatility beyond automotive applications.

Certifications and Quality Assurance

DIAN STAMPING operates under a robust quality management framework. The company holds IATF 16949 certification, the automotive industry's most stringent quality standard, as well as ISO 9001 and TUV certifications. Recognized as a National High-Tech Enterprise and a Zhejiang Provincial Technology-based SME, the company is equipped with a dedicated R&D laboratory and continuously invests in automated production lines and advanced inspection equipment, including CMM (coordinate measuring machines) and 3D scanning systems.
