Характеристики

Jixing picks are produced by drawing. The computer calculates the weight of the pick and then cuts it. After extrusion by warm extrusion technology, there is no flash burr and no oxide scale. The material utilization rate is over 95%.
The picks are made by temperature extrusion technology. The temperature is extruded at a metal recrystallization temperature. The forming temperature is about 600-800 degrees Celsius. In this temperature range, the metal no longer produces oxidation and grain length. Large forging defects can occur in the process of deformation and recrystallization, accompanied by partial normalizing process, which can significantly change the metallographic structure of the tooth body, refine the grain and improve the impact toughness of the pick.
