Poor dimensional accuracy of PET extruded profiles
Sorun Belirtisi
Large cross-section dimensional fluctuation of PET extruded profiles, difficult to meet precision assembly requirements.
Neden Analizi
Unstable extruder output (rotation speed fluctuation or uneven feeding), insufficient or uneven sizing die cooling, unstable haul-off speed.
Çözüm
Use metering feeding device to stabilize supply; optimize sizing die cooling design; precisely control haul-off speed (closed-loop servo); stabilize extrusion temperature ±2°C.
Temel Çıkarım
PET profile dimensional accuracy requires stable control of the entire process.
