Custom Ground Tungsten Carbide Rod, Shafts, Gage & Ejector Pins

Specializing in custom grinding services for various types of precision tungsten carbide parts, our product range includes tungsten carbide rods, shafts, gauges, and ejector pins. We utilize premium tungsten carbide materials processed through precision grinding techniques, with tolerance accuracy of ±0.001mm, ensuring products possess high hardness, excellent wear resistance, and superior dimensional stability.

Tungsten Carbide Gauges and Ejector Pins

Tungsten carbide gauges (such as pin gauges) are used for precision measurement and centering positioning. When measuring blind holes in parts, conventional methods are inadequate, requiring gauges for positioning and measurement. Using other materials can lead to easy wear, resulting in inaccurate measurement data. Pin gauges made from tungsten carbide material, with their high hardness and wear resistance, ensure stable accuracy throughout multiple measurement cycles. Tungsten carbide ejector pins are commonly used in ejection mechanisms for injection molding and stamping dies, featuring wear and corrosion resistance characteristics suitable for high-speed mold operations. We support custom processing from drawings and samples, offering various specifications and tolerance grades of tungsten carbide rods, ground shafts, pin gauges, ejector pins, and other products. Our comprehensive processing procedures include surface grinding, external cylindrical grinding, internal cylindrical grinding, combined internal and external cylindrical grinding, centerless grinding, and PG profile grinding. The finely ground surfaces feature high flatness with no visible scratches, ensuring mating accuracy and smooth operation during use.
