Jinhong thread core pin is made from the
finest grade hotwork die steel. The surface could be ion nitride coated and the core of vacuumed pin could be hardened according to the customer requirement. Our coating is done in a proprietary
process that produces an ideal combination of toughness and long life. The high surface finish reduces friction and increases pin service life. If you have requirements, we could reach the 0002″
tolerance.
