Our Core Capabilities: Stamping & Deep Drawing Die Design & Fabrication
We specialize in custom design and manufacturing of sheet metal stamping dies and deep drawing dies, which are widely applied in automotive, electronics, home appliances, hardware and other key industries. Our core function is to provide high-precision, durable and cost-effective die solutions that match the specific production needs of customers, ensuring efficient and stable mass production of parts. Backed by a professional technical team of 35+ engineers and technicians, we adopt advanced CAD/CAM/CAE design software (including UG, AutoCAD, SolidWorks) to simulate the stamping and deep drawing process in advance, optimizing die structure and avoiding potential defects in the production stage.
Key Production Processes & Technical Advantages
Our stamping and deep drawing die production process adheres to strict industry standards, covering: 1. Design & Simulation (process analysis, 3D modeling, finite element simulation); 2. Raw Material Selection & Cutting (high-quality alloy steel, precise cutting by CNC flame cutting machine); 3. Precision Machining (CNC milling, grinding, EDM, wire cutting with high precision); 4. Assembly & Debugging (professional assembly by skilled workers, multi-times debugging to ensure performance);5. Quality Inspection & Delivery (comprehensive inspection by CMM and other precision equipment). In addition to stamping and deep drawing dies, we also provide supporting processes such as sheet metal forming, welding, surface treatment and assembly to realize one-stop service for customers.
Common Problems & Solutions in Die Design & Fabrication
• Problem 1: Wrinkling in deep drawing process - Solution: Optimize the blank holder force and die cavity structure through simulation analysis, select appropriate blank size, and add anti-wrinkle ribs in key positions.
• Problem 2: Poor dimensional accuracy of stamped parts - Solution: Adopt high-precision machining equipment to ensure the machining accuracy of die parts, strengthen the rigidity of the die, and conduct real-time monitoring and adjustment during the debugging process.
• Problem 3: Short service life of dies - Solution: Select high-quality wear-resistant alloy steel (such as Cr12MoV) as raw materials, conduct heat treatment (quenching and tempering) to improve the hardness and toughness of die parts, and optimize the die structure to reduce stress concentration.

Customer Case: Automotive Stamping Die Project for European Client
Our client is a well-known automotive parts manufacturer in Germany, specializing in the production of automotive chassis parts. They encountered problems of low production efficiency and poor dimensional stability in the production of automotive chassis brackets due to the backwardness of their original dies. In 2023, they cooperated with us to customize stamping dies for automotive chassis brackets.
According to the client's requirements, our technical team conducted in-depth analysis of the product structure and production process, used UG software for 3D modeling and finite element simulation, optimized the die structure and stamping process, and solved the problem of stress concentration in the original die design. We selected Cr12MoV alloy steel as the die material, and adopted strict heat treatment process to improve the die's wear resistance and service life. During the production process, we strictly implemented the quality control system, and each key process was inspected by professional inspectors.
The final delivered dies achieved the following results: the dimensional accuracy of the stamped chassis brackets reached ±0.01mm, which fully met the client's requirements; the production efficiency was increased by 10% compared with the original dies; the die service life was guaranteed to be more than 500,000 strokes. The client highly recognized our product quality and technical service, and has established a long-term cooperative relationship with us.
