PET Preform Surface Flow Marks

Flow marks = melt front.

Molds & Tooling PET; preform; flow mark; hot runner; speed

PET Preform Bubbles

Bubbles = water or vacuum.

Material Drying PET; preform; bubble; drying; holding pressure

PET Preform Unstable Injection Cycle

Cycle = system stability.

Material Drying PET; preform; cycle; plasticization; temperature control

PET Preform Recycled Material Utilization

Preform reuse = ratio + drying + IV monitoring.

Material Drying PET; preform; recycling; IV; drying

PET Bottle Drop Rupture

Material Drying PET; bottle blowing; drop; rupture; embrittlement; bottom

PET Bottle Cap Slipping Threads

Slipping threads = neck dimensions and condition.

Molding Process PET; bottle neck; thread; slipping threads; dimension

PET Sheet Gel Particles

Gel particles = plasticization and filtration.

Molding Process PET; sheet; gel particle; filter screen; plasticization

PET Preform Weld Line

Preform weld line = weak band in blowing.

Molds & Tooling PET; preform; weld line; venting; hot runner

PET Preform Storage Deformation

Preforms also fear heat and pressure.
