A viewer designed to detect weaknesses and stress points in PET preforms through polarized light, revealing defects via a colored birefringence pattern. It offers advanced viewing capabilities, user-friendly design, and comes in three models to accommodate various inspection needs.
PET Preform Stress Viewer
The PL-P Polarization Light for Preform is a specialized tool designed to identify weaknesses and stress points in PET containers. This high-precision viewer uses polarized light to detect defects, revealing them through a colored birefringence pattern.
Advanced Viewing Capabilities
The colored birefringence pattern highlights the molecular strain that occurs during the injection molding process. This stress viewer helps the operator identify isochromatic fringes and black isoclines, which indicate birefringence and the direction of molecular strain, respectively. Accurate interpretation of these patterns allows for early detection of preform defects.
User-Friendly Design
The PL-P features an adjustable viewing angle, allowing operators to inspect preforms from various angles easily. Its expanded viewing area and sample platform can accommodate multiple preforms at once, enabling more efficient inspections. The hands-free operation further enhances usability, making it a valuable tool for quality control.
Three Models to Meet Your Needs
The PL-P is available in three sizes—Standard, Large, and Keg—to suit different sample sizes and inspection requirements.
Technical Specifications
Efficient and Reliable
The PL-P Polarization Light for Preform provides reliable detection of preform defects, enhancing your quality control processes. Its advanced design and user-friendly features make it an ideal choice for professionals seeking precise strain analysis in PET containers.
The PL-P Polarization Light for PET Preform is designed to detect weaknesses and stress points in PET containers by using polarized light. It reveals defects through a colored birefringence pattern, which helps in identifying molecular strain that may affect the integrity of the preforms.
The viewer utilizes polarized light to highlight isochromatic fringes and black isoclines in the PET preforms. These patterns indicate the presence of birefringence and the direction of molecular strain, allowing operators to accurately assess the quality and potential defects in the preforms.
The PL-P is available in three models: Standard, Large, and Keg. Each model is designed to accommodate different sample sizes and inspection needs, providing flexibility for various quality control applications.
The PL-P features a light source of 2 x 18 watt fluorescent lamps and operates on a power supply of either 110 or 220 volts. The viewing areas and overall sizes vary by model, with the Standard model measuring 13” x 6” (330 x 150 mm), the Large model at 13.8” x 13.8” (350 x 350 mm), and the Keg model at 17.7” x 17.7” (450 x 450 mm).
