Preform Thickness Gauge

High precision measurement for determining material concentricity and distribution of PET preforms

Category: Brand Partner:


The Preform Thickness Gauge provides automatic measuring for material thickness and concentricity of PET and PET/PEN preforms. The measurement cell is equipped with four ultrasonic sensors and a universal preform fixture. This ultrasonic measuring instrument provides precise, repeatable and reproducible thickness measurement over a cross section of the preform.

Easily detect core shift and bent cores

Eliminate the need for elaborate fixturing
