Core Business: Custom Progressive Stamping Die Design & Fabrication
We specialize in the customized design and manufacturing of progressive stamping dies, a core product that enables continuous multi-process stamping operations for high-efficiency mass production. Our progressive stamping dies are engineered to deliver precise, consistent forming of sheet metal parts, covering blanking, bending, forming, and piercing in a single pass—significantly enhancing production efficiency and reducing labor costs for our clients. These dies are widely applied in key industries such as automotive, electronics, home appliances, and hardware. Backed by a professional technical team of 35+ engineers and technicians, we leverage advanced CAD/CAM/CAE software (including UG, AutoCAD, and SolidWorks) to conduct in-depth process simulation and structural optimization, ensuring die performance and product precision from the design stage.
Production Process & Supporting Technologies
Our progressive stamping die production adheres to a strict, standardized workflow to guarantee quality and efficiency:1. Demand Analysis & Design (client requirement confirmation, 3D modeling, process flow simulation, and die structure design); 2. Raw Material Preparation (selection of high-quality alloy steel, precision cutting via CNC flame cutting); 3. Precision Machining (CNC milling, grinding, EDM, wire cutting with ultra-high precision to ensure die part accuracy); 4. Assembly & Debugging (skilled manual assembly, multi-round debugging to optimize stamping continuity and part quality); 5. Quality Inspection & Delivery (comprehensive testing using coordinate measuring machines (CMM) and other precision equipment). In addition to progressive stamping dies, we also offer supporting processes including sheet metal forming, welding, surface treatment, and final assembly, realizing a full-chain service for our clients.
Common Challenges & Solutions in Progressive Stamping Die Production
• Challenge 1: Misalignment between consecutive stamping stations - Solution: Adopt high-precision guide pillars and bushings in die design, optimize the positioning pin structure, and conduct rigorous debugging of station spacing during assembly to ensure consistent alignment; use wear-resistant materials for key positioning components to maintain accuracy during long-term production.
• Challenge 2: Material wrinkling or tearing during multi-process forming - Solution: Utilize CAE simulation to analyze material flow during each stamping stage, adjust blank holder force and die cavity curvature, and add material guide devices to ensure uniform material stretching; select appropriate blank sizes and material thicknesses based on product requirements.
• Challenge 3: Poor surface quality of stamped parts (scratches, burrs) - Solution: Polish the die's working surfaces to a high finish, apply wear-resistant and lubricating coatings to contact areas, optimize the stamping speed and lubrication system, and strictly control the surface quality of raw materials.

Customer Case: Progressive Stamping Die for North American Electronic Connector Client
Our client is a leading electronic component manufacturer in the United States, specializing in the production of high-precision connectors for the automotive electronics industry. They faced challenges with their previous progressive stamping dies, including low production efficiency (only 300 parts per hour) and frequent station misalignment, which led to high scrap rates (over 5%). In 2022, they partnered with us to develop a custom progressive stamping die for their core connector pin product.
Our technical team first conducted a detailed analysis of the client's product drawings and production requirements, using UG software to build a 3D model of the progressive die and simulate the 8-station stamping process. We optimized the die's guide structure by adopting imported high-precision guide pillars and bushings, and designed a floating positioning pin system to solve the alignment issue. For the die material, we selected Cr12MoV alloy steel and implemented a strict quenching and tempering process to enhance wear resistance. During the assembly stage, our technicians conducted 10+ rounds of debugging, adjusting the blank holder force and stamping speed to ensure smooth material flow and consistent part quality.
The final delivered progressive stamping die achieved remarkable results: production efficiency increased to 800 parts per hour (a 167% improvement), and the scrap rate dropped to less than 0.5%. The connector pins met the client's strict precision requirement of ±0.008mm. Impressed by our product quality and technical support, the client established a long-term cooperative relationship with us.
