Improper parison wall thickness, temperature, and length control affecting blow molded product quality
Problembeschreibung
Improper parison wall thickness, temperature, and length control affects blow molded product quality
Ursachenanalyse
Insufficient parison wall thickness control accuracy
Uneven parison temperature, severe sag
Parison length control deviation
Unstable parison extrusion speed
Styrene-butadiene transparent resin (K resin) parison viscoelasticity affects wall thickness distribution
Lösung
Use a wall thickness controller to precisely control parison wall thickness
Stabilize parison extrusion temperature to reduce sag
Precisely control parison length
Stabilize parison extrusion speed
Adjust parison parameters according to styrene-butadiene transparent resin (K resin) viscoelasticity
Wichtigste Erkenntnis
Parison needs precise control of wall thickness and temperature
