Progressive metal stamping die for electronic components

　　Progressive metal stamping die for electronic components

　　When selecting or customizing progressive metal stamping dies for electronic components, the core factors to prioritize include micro-precision machining capability, high-speed operation stability, multi-process integration, material compatibility (for thin/soft electronic metal materials), and die wear resistance. Below are recommended die types with their core features, tailored for progressive stamping scenarios of various electronic components such as micro-connectors, chip pins, battery components, and electronic gaskets:

　　Single-Station Blanking Die for Simple Sheet Metal Parts

　　A high-precision die type specialized for progressive stamping of micro-electronic connectors (feature size ≤0.1mm), such as board-to-board connectors and FPC connectors. It integrates multiple micro-processes including micro-blanking, micro-punching, micro-bending, and forming in 6-12 consecutive stations. The key working parts (punch, die insert) are made of ultra-fine grained tungsten carbide (WC-Co 90/10) with surface roughness Ra ≤0.02μm, ensuring micro-precision machining and long-term wear resistance. Equipped with a servo-driven micro-feeding mechanism (positioning accuracy ≤±0.005mm) to avoid material deviation during high-speed feeding (800-1200 strokes per minute). The die is designed with a dust-proof and anti-static structure, adapting to the clean production requirements of electronic components. Suitable for mass production of micro-electronic connectors, with the advantages of high dimensional accuracy (tolerance ≤±0.008mm), good part consistency, and strong adaptability to thin copper/aluminum alloy sheets (thickness 0.03-0.2mm).

　　Compound Blanking Die for Precision Sheet Metal Parts

　　A specialized die type tailored for progressive stamping of chip pins (such as CPU pins, memory chip pins) that require high straightness and conductivity. It integrates blanking, pin forming, trimming, and surface flattening processes in one die, with 8-15 stations arranged in a reasonable sequence. The working parts are made of high-hardness die steel (SKD11) with titanium nitride coating, which balances wear resistance and machining precision, and avoids scratching the metal surface (ensuring conductivity). Equipped with a floating pressure plate with micro-adjustable pressure to prevent deformation of thin metal strips (thickness 0.05-0.3mm) during stamping. The die is equipped with a real-time monitoring system for pin straightness, which can detect unqualified parts in real time and reduce scrap rate. Suitable for mass production of chip pins made of copper alloy or stainless steel, with stamping speed of 500-800 strokes per minute. It has the advantages of high pin straightness (≤0.01mm/m), stable electrical performance, and compatibility with automatic chip packaging lines.

　　Progressive Blanking Die for Complex Sheet Metal Parts

　　A high-efficiency die type designed for progressive stamping of lithium battery components, such as battery tabs, positive/negative electrode sheets, and battery shells. It integrates blanking, notching, folding, and welding groove forming processes, with 4-8 stations to meet the high-speed production needs of the battery industry. The working parts are made of wear-resistant D2 die steel or tungsten carbide inserts (for key positions), which can withstand the high-speed stamping of aluminum/copper foils (thickness 0.01-0.1mm) at 1000-1500 strokes per minute. Equipped with a vacuum adsorption feeding mechanism to ensure smooth feeding of ultra-thin metal foils without wrinkles. The die is designed with a clean lubrication system, using food-grade lubricants to avoid contaminating battery materials. Suitable for large-scale battery production lines, with the advantages of high production efficiency, low material loss (scrap rate ≤0.5%), and good compatibility with battery assembly automation. The die is also equipped with a material thickness detection function to adapt to different specifications of battery materials.

　　Fine Blanking Die for High-Strength Sheet Metal Parts

　　A cost-effective die type suitable for progressive stamping of electronic gaskets (such as EMI shielding gaskets, waterproof gaskets) with simple to medium complexity. It integrates blanking, hole punching, and edge trimming processes in 3-6 stations, suitable for metal materials such as stainless steel, copper alloy, and nickel alloy (thickness 0.1-0.5mm). The working parts are made of Cr12MoV die steel after quenching and tempering heat treatment (HRC 58-62), ensuring wear resistance and machining precision. Equipped with a roller feeding mechanism (positioning accuracy ≤±0.01mm) and a pressure-adjustable pressure plate to ensure the flatness of gaskets (≤0.02mm). The die is designed with an automatic waste discharge mechanism to avoid waste accumulation affecting stamping efficiency. Suitable for small-batch to mass production of electronic gaskets, with stamping speed of 300-600 strokes per minute. It has the advantages of simple structure, easy maintenance, and stable gasket size accuracy (tolerance ≤±0.015mm), meeting the sealing and shielding requirements of electronic products.

　　Customized Blanking Die for Special-Shaped Sheet Metal Parts

　　A personalized die type designed according to the 3D model of special-shaped electronic components (such as asymmetric sensors, custom connectors). The station layout and process integration are customized based on the part's shape and processing requirements, integrating 5-18 processes such as blanking, multi-angle bending, forming, and piercing. The working parts are selected from suitable materials (tungsten carbide, SKH-9 high-speed steel) according to the stamping material and precision requirements. Equipped with a special precision positioning mechanism (such as pin positioning + visual auxiliary positioning) to ensure the accuracy of special-shaped parts during progressive stamping. The die structure is optimized by finite element analysis to enhance rigidity and stability during high-speed operation (400-700 strokes per minute). Suitable for small-batch to mass production of special-shaped electronic components in the automotive electronics, medical electronics, and industrial control fields. Although the design and manufacturing cycle is relatively long, it can meet the personalized processing needs of non-standard electronic components, ensuring shape consistency and performance stability.

　　High-Speed Blanking Die for Thin Sheet Metal Parts

　　A specialized die type tailored for progressive stamping of electrostatic-sensitive electronic components (such as semiconductor components, sensor shells). It integrates anti-static design into the die structure, including anti-static coatings on the die surface, conductive material components, and grounding devices to avoid electrostatic damage to components. The working parts are made of ultra-fine grained tungsten carbide with good conductivity, ensuring smooth electrostatic discharge during stamping. Equipped with a clean feeding system and dust-proof cover to prevent dust and impurities from contaminating sensitive components. The stamping speed is controlled at 300-600 strokes per minute to reduce electrostatic generation caused by high-speed friction. Suitable for cleanroom production of sensitive electronic components, with the advantages of electrostatic protection (static voltage ≤50V), high processing precision, and compliance with electronic component clean production standards. The die is also equipped with a static monitoring system to real-time monitor the electrostatic state during stamping, ensuring component safety.
