China’s precision of the punch heads, ejector core pins, date stamp or other mold/die parts, which are the replaceable consumable components, can reach ±0.002mm by professional manufacturers. The quality can reach the first class in the international market. The high precision and consistency require each of mass production in accordance with the dimensional tolerance, which can achieve the maximum service life of the mould/die.

The punchs and pins used in industrial production for stamping die is generally made of high-speed steel and tungsten steel as material. Being made of different shapes, the mass hole processing are capable according to the different needs on the large punch bed. For example, the computer dissipation plate with a lot of heat dissipation holes.

Tungsten punch has a high demand for the material toughness, the technical threshold and the production cost. The raw materials are mainly imported. The heat treatment also need considerate quenching and tempering temperature and ultra-cold duration according to the specific use environment.

GP precision guide pillars bushes and ball-bearing guide pillars guide bushes，for plastic mold frame and large stamping die frame, is to guide direction and improve the performance of the safety and preparation work. The guide pillar is used in combination with other components in the mold to ensure that the mold moves with accurate position and route. There are three types ball-bearing guide pillars guide bushes -aluminium alloy steel ball sleeve, copper alloy base steel ball sleeve, and POM steel ball sleeve.
