PET Bottle Insufficient Top Load Strength

Lightweighting forces top load management.

Extrusion & Post PET; bottle blowing; top load strength; wall thickness distribution; lightweighting

PET Preform Aging (Long Inventory)

Old preforms = hardened preforms; temperature compensation must keep up.

Extrusion & Post PET; preform; aging; IV; oven temperature

PET Bottle Insufficient High-Pressure Air

High-pressure air is the guarantee of the last millimeter of stretching.

Extrusion & Post PET; bottle blowing; high-pressure air; pressure curve; air storage tank

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 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 Pearlescence (Stress Whitening)

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

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

PESU Membrane and Coating

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

PESU Solution Processing

Extrusion & Post PESU;solution processing;coating;solvent;environmental protection;test
