PET Bottle Transfer Interval Too Long

From preform leaving the oven to blowing = a race against 2 seconds.

Extrusion & Post PET; bottle blowing; transfer time; secondary crystallization; pearlescence

PET Bottle Unreasonable Heating Temperature Gradient

The lamp zone gradient is the core parameter of the blow '2079851475616104453.

Extrusion & Post PET; bottle blowing; heating gradient; lamp zone; temperature field

PET Preform Excessive Drying Crystallization

Drying is not the longer the better; over-drying = pre-crystallization.

Material Drying PET; preform; excessive drying; crystallization; white haze

PET Bottle Uneven Wall Thickness

Extrusion & Post PET; bottle blowing; uneven wall thickness; lamp zone; stretch rod

PET Preform Poor Concentricity

Extrusion & Post PET; preform; concentricity; off-center bottom injection point; wall thickness

PET Bottle White Haze (Crystallization Type)

Molding Process PET; bottle blowing; white haze; crystallization; excessive heating

PET Bottle Pearlescence (Stress Whitening)

Pearlescence = cold stretching; give the heat to the whitening area.

Extrusion & Post PET; bottle blowing; pearlescence; stress whitening; heating lamp zone

PET Preform Insufficient Drying (Hydrolysis)

Material Drying PET; preform; drying; hydrolysis; white haze

PESU Membrane and Coating

Extrusion & Post PESU; membrane; coating; solution; separation; protection

PESU Food Service

Processing Machinery PESU; food service; FDA; transparent; hygiene; durable
