　　High-speed metal stamping die with tungsten carbide

　　When selecting or customizing a high-speed metal stamping die with tungsten carbide, the core factors to prioritize include tungsten carbide grade matching, die structure rigidity, high-speed operation stability, wear resistance, and compatibility with stamping materials. Below are recommended die types with their core features, tailored for high-speed stamping scenarios of various metal parts such as electronic components, automotive precision parts, hardware fittings, and thin metal foils:

　　Single-Station Blanking Die for Simple Sheet Metal Parts

　　A basic and widely used high-speed die type, mainly suitable for high-speed stamping of thin metal parts (thickness ≤1mm) with simple shapes (such as circles, squares, gaskets). The key working parts (punch and die insert) are made of fine-grained tungsten carbide (such as WC-Co 94/6), which has ultra-high hardness (HRA 90-92) and wear resistance, ensuring stable precision during long-term high-speed stamping (300-800 strokes per minute). The die frame adopts high-strength alloy steel with integral forging, enhancing rigidity and reducing deformation under high-frequency impact. Equipped with high-precision linear guide rails and floating pressure plate device, which can realize precise guiding and prevent material displacement during high-speed feeding. Suitable for mass production of electronic product gaskets, battery shell components, and thin metal foils, with the advantages of long service life (5-10 times that of traditional die steel dies) and low scrap rate. The tungsten carbide inserts are designed with modular structure, convenient for replacement and maintenance, reducing downtime loss.

　　Compound Blanking Die for Precision Sheet Metal Parts

　　A high-efficiency and high-precision die type composed of multiple consecutive stations, integrating blanking, punching, bending, and forming processes. It is mainly suitable for high-speed stamping of complex-shaped precision metal parts (dimensional tolerance ≤±0.01mm) such as mobile phone middle frames, automotive precision connectors, and microelectronic components. All key working parts are made of ultra-fine grained tungsten carbide (WC-Co 92/8) with excellent toughness and wear resistance, which can withstand the impact of high-speed stamping (800-1200 strokes per minute) and avoid chipping. Equipped with a servo-driven precision feeding mechanism (positioning accuracy ≤±0.005mm) and real-time monitoring system, which can detect feeding deviation and die wear in real time. The die is designed with a forced lubrication and cooling system to reduce friction between tungsten carbide parts and metal materials, and prevent overheating affecting die life. Suitable for fully automatic high-speed stamping production lines, with the advantages of high production efficiency, good part consistency, and strong adaptability to high-strength metal materials (such as stainless steel, titanium alloy thin sheets).

　　Progressive Blanking Die for Complex Sheet Metal Parts

　　A specialized die type designed for high-speed blanking of high-strength metal sheets (such as high-strength steel, spring steel, with thickness 1-3mm) in automotive and aerospace fields. The punch and die are made of impact-resistant tungsten carbide (WC-TiC-Co) composite material, which combines high hardness (HRA 91-93) and excellent impact toughness, effectively avoiding brittle fracture during high-speed blanking of hard materials. The die structure adopts a pre-tightening sleeve design to enhance the bearing capacity of tungsten carbide parts and reduce stress concentration. Equipped with a hydraulic buffer device to absorb the impact energy during high-speed stamping, protecting the die and stamping equipment. The blanking gap is precisely designed according to the material characteristics, ensuring smooth blanking section and reducing burrs. Suitable for mass production of automotive safety parts (seat belt components, airbag brackets) and aerospace precision blanks, with stamping speed up to 500-700 strokes per minute. It has the advantages of long service life, stable blanking quality, and reduced subsequent processing procedures.

　　Fine Blanking Die for High-Strength Sheet Metal Parts

　　A miniaturized high-speed die type tailored for micro electronic components (such as micro connectors, chip pins, with feature size ≤0.1mm). The tungsten carbide parts are processed by precision grinding and EDM (Electrical Discharge Machining) with surface roughness Ra ≤0.02μm, ensuring the precision of micro structures. It adopts ultra-fine grained tungsten carbide (WC-Co 90/10) with high wear resistance, which can maintain precision during high-speed stamping of micro parts (1000-1500 strokes per minute). Equipped with a micro-precision positioning system and a dust-proof and anti-static device, adapting to the processing requirements of micro electronic components. The die is designed with a lightweight structure to reduce inertial force during high-speed operation, and the guide mechanism uses ultra-precision ball bearings to ensure smooth operation. Suitable for mass production of micro electronic components in the semiconductor and electronic manufacturing industries, with the advantages of high micro-precision, stable processing quality, and long die life. The assembly of tungsten carbide parts adopts interference fit technology to ensure positional accuracy.

　　Customized Blanking Die for Special-Shaped Sheet Metal Parts

　　A personalized die type designed according to the 3D model of special-shaped metal parts (such as curved surfaces, asymmetric structures, special holes) that require high-speed stamping. The tungsten carbide working parts are customized according to the shape of the special-shaped parts, and the material grade is selected according to the stamping material (soft materials such as aluminum alloy, copper alloy or hard materials such as stainless steel). Equipped with a special precision positioning mechanism to ensure the accurate positioning of irregular parts during high-speed stamping; for thin-walled special-shaped parts, a flexible pressure plate made of polyurethane is used to avoid material deformation. The die structure is optimized by finite element analysis to enhance rigidity and stability during high-speed operation (300-600 strokes per minute). Suitable for small-batch to mass production of special-shaped parts such as custom hardware accessories, medical equipment components, and precision instrument parts. Although the design and manufacturing cycle is relatively long, it can meet the high-speed stamping needs of non-standard special-shaped parts, ensuring shape consistency and processing efficiency.

　　High-Speed Blanking Die for Thin Sheet Metal Parts

　　A high-performance die type designed for high-speed stamping of multi-process automotive parts (such as automotive door hinges, engine gaskets, transmission components). It integrates multiple processes such as blanking, punching, bending, and trimming in one die, with multiple stations arranged in sequence. The key working parts are made of wear-resistant and impact-resistant tungsten carbide (WC-Co 93/7), which can withstand the long-term high-speed stamping of automotive high-strength steel sheets (stamping speed 400-800 strokes per minute). Equipped with a high-precision servo feeding system and an automatic waste discharge mechanism, realizing fully automatic high-speed production. The die is also equipped with a die protection system, which can stop the machine immediately when abnormal conditions (such as material shortage, die jamming) occur, protecting the tungsten carbide parts from damage. Suitable for large-scale automotive parts production lines, with the advantages of high production efficiency, good part consistency, and strong adaptability to automotive production rhythms. The tungsten carbide parts are designed with wear compensation structure, extending the die's service life and reducing maintenance frequency.
