Thorough Hardened Screw HPT Series

Through hardened HPT series screw is made of imported alloy steel. After high-temperature quenching and tempering
treatment,the hardness of the round rod reaches to HRC60. Under the different types of rough & fine grinding progress,
the concentricity of the core diameter and outer diameter reaches 0.03mm. It can meet the high-precision requirements
of various products and prolong the screw’s serving life in different applications. HPT series are suitable for plastic
material with 25%-65% glass fiber, with wear-resistance, corrosion-resistance, high-temperature resistance, high-pres
sure resistance, and high-speed resistance property, and they are suitable for fully electrical injection molding machine
with high speed and high processing requirements. According to the different customers demands, the PVD coating and
Chrome plating are applied to improve the wear-resistance and corrosion-resistance.
