PL-P
Polariscope for preforms
Technical characteristics :
Viewing area:
330mm x 150mm
Or 350x350 mm
Dimensions:
400 (L) x 302 (W) x 305 (H) mm
Or
350x350x400mm
Light source:
45watt (LED lamps)
Food:
220/240 volts
Description :
The PL-P reveals many defects in PET preforms. Preforms are exposed to polarised light, which highlights internal stress. These optical defects result from how the polymer behaves during injection. Colour fringes seen under polarised light at 45° and 90° — known as isochromatic fringes — indicate the level of stress and its causes, and the light also shows the direction of the stress. A defect-analysis catalogue is supplied. With its adjustable angle, the PL can be used sitting or standing and holds preforms steadily for comparison; its large size also allows inspection of large preforms, for water-cooler bottles for example.

FAQ
What is the primary function of the PL-P polariscope for preforms?
The PL-P detects internal stress defects in PET preforms by exposing them to polarized light, revealing stress patterns caused by polymer reactions during injection molding.
How does the PL-P reveal stress in preforms?
On the PL-P, color reflections visible under polarized light at 45° and 90° angles - known as isochromatic brightness - indicate the amount and direction of stress in the preform material, with an available defect-analysis catalog for interpretation.
What viewing area and ergonomics does the PL-P offer?
The PL-P offers a viewing area of 330 x 150 mm (or 350 x 350 mm option), with adjustable angular positioning allowing operators to work seated or standing.
What lighting and power specifications does the PL-P use?
The PL-P uses a 45-watt LED light source running on 220/240V (110V optional), with dimensions of 400 x 302 x 305 mm (or larger configuration).
