Frequently Asked Questions
GF-reinforced grades (GF-PP, GF-PET, GF-PA), mineral-filled compounds (talc/CaCO₃-filled PP/PE), carbon fiber reinforced, engineering plastics with hard fillers.
Automotive structural parts (bumpers, under-hood), industrial containers, pipe/profile extrusion, construction materials, high-strength consumer goods.
Bimetallic or fully hardened screw and barrel, customized screw geometry.
Glass fibers (Mohs hardness ~7) act like cutting tools under high shear & temperature, rapidly eroding screw flights and barrel bore.
Use bimetallic barrels and alloy screws, and maintain regular inspection.
