Tungsten Carbide Thimble Carbide Punching Pin

Tungsten Carbide Thimble Carbide Punching Pin

Tungsten Carbide Thimble Carbide Punching Pin  is a ejector pin made of high-quality tungsten carbide material ground and polished by precision equipment. It is commonly referred to as ejector pin, support pin, double section ejector pin, flat ejector pin, embedded pin, or PIN pin. Due to its use of high-quality tungsten carbide material with high hardness of 92.0HRA and bending strength of 4000MPa, it has high wear resistance and excellent corrosion resistance. It is usually used in plastic molds to separate plastic products from the mold, and can also be used to pass through thin and long pinholes. It is also often used on lathes and grinders to support workpieces and rotate them around it. It is also suitable for making tungsten electrode rods in the optoelectronic industry, with a tip angle controlled between 10 ° and 15 °. It is mainly used on automatic solidification machine equipment to support (top up) auxiliary vacuum adsorption systems.
