How one Zhejiang-based manufacturer combines factory-direct pricing, in-house engineering, and end-to-end production to serve global OEMs.
If you source automotive stamping dies from China, you have likely run into the same dilemma: the company that quotes you the best price may not be the one that actually builds the tooling. Trading companies, brokers, and multi-layer supply chains are common in the industry, and they often introduce communication gaps, quality inconsistencies, and extended lead times.
LINHAI DIAN MOULD CO., LTD (Dian Stamping Company) was founded in 2003 in Huangyan, Taizhou, Zhejiang Province, specifically to solve this problem. With over 20 years of experience, a 50,000 m² production facility, and a team of approximately 110 employees including 35 die designers and technicians, Dian Stamping operates as a true factory-direct stamping die manufacturers — not a trading company. Every die, fixture, and stamped part is engineered, machined, assembled, and tested under one roof.
A Facility Built for Automotive-Grade Precision
Dian Stamping's current facility spans 50,000 m², with a dedicated 4,000 m² die workshop. The company produces approximately 2,000 sets of medium and small stamping dies annually, with an annual die turnover of roughly RMB 50 million. These are not simple tools — they are precision stamping dies (progressive, transfer, and tandem configurations) designed for complex, medium-to-large automotive parts.
A new 35,000 m² facility is also in the planning stage, which will add a press line and coating lines, further expanding the company's vertical integration capabilities.
Key figures at a glance:
• Founded: 2003 | Facility: 50,000 m² | Die workshop: 4,000 m²
• Employees: ~110 | Die designers & technicians: ~35
• Annual die output: ~2,000 sets | Annual die turnover: ~RMB 50 million
Trusted by Global Automotive Brands
Dian Stamping supplies tooling and stamped parts to OEMs including KIA, BYD, Toyota, Honda, Suzuki, and Geely, and exports to over 10 countries. These customers do not approve suppliers lightly — they audit facilities, validate quality systems, and demand consistent delivery. Dian Stamping has maintained these relationships by meeting strict OEM standards year after year, across multiple vehicle programs.
Four Integrated Product Lines
Unlike many die shops that only offer tooling, Dian Stamping provides a complete manufacturing ecosystem. This means your die development, tryout, production stamping, and inspection can all be managed in one place.
The checking fixture service is particularly valuable for OEMs and Tier suppliers who need to verify part geometry before mass production. Designed and built in-house, these fixtures follow GD&T principles and are tailored to each part's specific datum structure, helping you catch dimensional issues early.
Applications Across the Vehicle
Dian Stamping's tooling and parts are used in a wide range of automotive systems:
- Body-in-white
- Door systems
- Seating systems
- Instrument panels
- Fuel-tank systems
- Exhaust systems
- Clutch systems
- Chassis systems
Materials capability includes multiphase steel, aluminum, custom rolled and welded plate, and stainless steel — covering the range of modern automotive lightweighting and strength requirements.
Quality Systems and Delivery
Dian Stamping operates under ISO 9001 quality management and follows IATF 16949-oriented practices. Customization is available from 2D drawings, 3D data, or physical samples. Prototype services are offered, and free metal samples are available (freight paid by the customer).
Typical lead times are 30 to 40 days for steel stamping dies and approximately 70 days for casting stamping dies, depending on project complexity and specifications.
The Factory-Direct Advantage
Because Dian Stamping controls every step of the process — die design, machining, assembly, tryout, stamping, and inspection — customers benefit from:
• Factory pricing with no intermediary markups
• Direct communication with the engineering team that builds your tooling
• Faster problem resolution when design changes or adjustments are needed
• Long-term supply relationships built on consistent quality and delivery
This is especially important for automotive stamping dies, where a single dimensional deviation can cascade into costly production delays. Having the die designer, die maker, and stamper under one roof significantly reduces that risk.
