Small Diameter Carbide Tooling – Punches & Ejector Pins

We specialize in manufacturing and selling various small-diameter tungsten carbide punches, ejector pins, and finished tools, serving as a reliable partner in the precision manufacturing field. Our minimum processing tip size is 0.2mm, with dimensional tolerances reaching ±0.001mm, concentricity tolerances of ±0.003mm, and cylindricity tolerances of ±0.003mm. We maintain precise dimensional tolerances through strict machining and inspection controls, ensuring that critical indicators such as product diameter, concentricity, and coaxiality meet high-standard requirements.

Our products are key components for achieving high-precision and high-efficiency production. Cemented carbide punches and ejector pins possess extremely high hardness and wear resistance, making them suitable for high-precision small-hole machining and frequent stamping operations. They maintain stability under complex conditions and extend tool service life. These products are widely applied in fields with extremely stringent dimensional requirements, including molds, electronic connector molds, micro motors, precision connectors, and medical devices.

Core Performance Features

Our products are manufactured from high-quality tungsten carbide and high-speed steel materials, ensuring the following core performance characteristics:

Exceptional Wear Resistance

Capable of withstanding prolonged and frequent friction and impact, our products offer extended service life and reduced downtime for replacements.

Outstanding Rigidity and Bending Resistance

Even at micro diameters, our products maintain excellent straightness and stability, ensuring precise stamping or ejection positions.

Our Competitive Advantages

Our core advantages lie in our focus on micro precision parts and rapid custom production capabilities. Whether for standard or non-standard parts, we provide highly competitive prices and consistent quality, effectively helping you reduce procurement costs and improve production efficiency.
