The screw and barrel are the "heart" of the extruder. Their wear resistance directly determines the equipment's service life and long-term stability. The screw and barrel of this production line are both made of high-quality 38CrMoAlA alloy steel, precision machined and then fully nitrided, achieving a surface hardness of HRC58-60.
This high-hardness, high-wear-resistance design effectively withstands long-term abrasion from PP materials (especially those containing glass fiber, fillers, or regrind), significantly extending the replacement cycle of core components. Additionally, the nitrided layer offers good corrosion resistance, suitable for processing modified PP such as flame-retardant grades.
