A Manufacturer Built for the Automotive Industry

Established in 2003 and headquartered in Linhai, Taizhou, Zhejiang Province, DIAN STAMPING is not a trading company but a full-fledged manufacturing facility spanning approximately 50,000 square meters. The company employs a dedicated team of around 110 professionals, including 35 die designers and technicians who bring deep domain expertise to every project. With an annual die production capacity of roughly 2,000 sets of medium and small stamping dies, and an annual die turnover of approximately RMB 50 million, the company has the scale and capability to support both high-volume production runs and custom-engineered tooling projects.

As a recognized National High-Tech Enterprise, DIAN STAMPING holds IATF16949, ISO 9001, and TUV certifications — credentials that are essential for any serious supplier to the global automotive supply chain. The company's quality management system is aligned with automotive industry standards, ensuring that every component leaving the factory floor meets stringent dimensional and material requirements.

Comprehensive Portfolio of Stamping Products and Services

DIAN STAMPING offers a one-stop, full-industry-chain service that covers everything from mold design and development to sheet metal stamping, welding processing, powder coating, and finished product assembly. The company's product portfolio is organized into four main categories, each designed to serve specific stages of the automotive production process:

The company's expertise in automotive stamping dies covers a wide range of vehicle systems, including body-in-white (BIW), door systems, seating systems, instrument panels, fuel tank systems, exhaust systems, clutch systems, and chassis systems. These are the structural and safety-critical components that define a vehicle's performance and reliability.

Material Versatility and Processing Capabilities

DIAN STAMPING handles a broad spectrum of materials commonly used in modern automotive manufacturing. The company's material processing capabilities include multiphase steel (advanced high-strength steel), aluminum alloys, custom rolled steel, welded plate, and stainless steel parts. This versatility allows the team to recommend the optimal material for each application, balancing weight reduction, strength requirements, and cost efficiency.

The upcoming 35,000 m² facility expansion will introduce new press lines and advanced coating capabilities, including electrophoresis and powder coating lines, further strengthening the company's ability to deliver fully finished, assembly-ready components directly to OEMs.

Proven Track Record with Global OEMs

DIAN STAMPING has built long-term relationships with some of the world's most recognized automotive brands, including KIA, BYD, Toyota, Honda, Suzuki, and Geely. The company exports to more than 10 countries, demonstrating its ability to meet international quality standards and delivery expectations. Whether working from 2D drawings, 3D CAD data, or physical samples, the engineering team collaborates closely with clients to develop custom tooling solutions that optimize production efficiency and part quality.

As one of the leading stamping die manufacturers in China, DIAN STAMPING handles all production in-house with no outsourcing, giving clients full control over quality, lead times, and cost. Typical delivery for steel stamping dies ranges from 30 to 40 days, while casting dies are delivered in approximately 70 days, subject to project scope and complexity.
