PET Preform Stress Viewer with Automatic or Manual Rotation System

AT2E’s new APL-P / MPL-P Polarization Light for Preform with Rotation System are designed to allow checking PET preforms for stress and defects in an easy and convenient way. Many of the defects found in PET preforms can be detected by using the APL-P or MPL-P systems.

Advanced Viewing Capabilities

Preforms viewed in a polarized light exhibit a colored birefringence pattern, which is the result of the polymer flow lines (molecular orientational strain) produced during the injection molding process. The colored pattern observed with preform indicates its qualities and eventual problems.  By correctly interpreting these flow patterns, many preform defects can be detected.

Efficient and User-Friendly Design

The design of the APL and MPL allows the operator to rotate the preforms being examined, providing complete observation of all surfaces, and hence a more detailed analysis. With up to 3 rows, they are designed to maximize the number of samples being examined simultaneously.

The APL-P is completely automated (it has an electric motor, with adjustable speed), while the MPL-P uses a side wheel for manual operation.

Several Models to Better Address User Needs

With 1, 2 or 3 viewing windows, able to check from 5 to 8 preforms in each window, with the possibility of manual wheel or electrical motor to rotate the samples, these devices allow a quick way to check several samples each time.

Efficient and Reliable

The APL-P / MPL-P units ensure reliable detection of preform defects, enhancing quality control processes. Its advanced design and user-friendly features make it a top choice for professionals seeking precise strain analysis in PET  preforms.
