Polariscope-Dx for PET & Preform

What is Polariscope-Dx for PET & Preform?

Polariscope-Dx is an advanced optical inspection system designed to evaluate internal stresses, birefringence, and material flow patterns in PET bottles and preforms. Built for quality-focused plastic manufacturers, it provides a clear, illuminated 3D view of stress distribution—helping users identify defects early, optimize production parameters, and ensure consistent product performance. With precise visualization and easy operation, Polariscope-Dx has become an essential tool for PET processing, injection molding, and packaging industries.

How does Polariscope-Dx for PET & Preform work?

Polariscope-Dx uses polarized light to analyze how PET material reacts when subjected to stress. When a PET preform or bottle is placed between two polarized filters, internal stresses cause the light to refract and create color patterns known as *isoclinicsand *isochromatics*. These patterns reveal:

• Uneven material distribution
• Cooling or orientation defects
• Mold-related stress
• Gate area irregularities
• Stretching inconsistencies

Operators can quickly assess the stress profile and make immediate adjustments to processing temperatures, mold design, cooling cycles, and stretch ratios—resulting in stronger, more uniform PET products.

What are the benefits of Polariscope-Dx for PET & Preform?

1. Enhanced Product Quality

Accurately detect hidden stress and inconsistencies that compromise bottle clarity, strength, and durability.

2. Reduced Production Waste

Early detection of defects helps minimize rejections, saving material, time, and operational costs.

3. Faster Troubleshooting

Instant visual feedback allows operators to make real-time adjustments to molding and stretching processes.

4. Improved Process Optimization

Helps maintain consistent processing parameters across shifts and machines, ensuring stable, repeatable quality.

5. Superior Packaging Performance

Optimized stress distribution results in PET containers with better pressure resistance, shelf stability, and aesthetic clarity.

6. User-Friendly Operation

Designed for both experienced engineers and new operators, with easy setup, low maintenance, and quick interpretation of results.
