Thermal Stability and Shrinkage Test Oven for PET Bottles

Forced-air oven that heats PET bottles at set temperature for a fixed time to measure dimensional shrinkage and distortion. Used by hot fill and aseptic bottle producers to verify heat set performance.

Specification

Bottles are placed on a perforated shelf at 60 to 90 deg C and kept for the specified time, then cooled and measured for height, diameter and volume change. The oven has a uniform air flow for repeatable ageing. Hot fill makers use it to qualify heat set grades.

Features

• Uniform forced-air circulation
• Digital PID control with timer
• Stainless steel interior and 3 shelves
• Door with viewing window and safety thermostat
• Range suited to heat set bottle trials up to 120 deg C
