Polymer and plastic preforms are integral components in the manufacturing of various devices and equipment. Known for their durability, reliability, and cost-efficiency, these materials are favoured by manufacturers across diverse industries. However, ensuring the quality and uniformity of these preforms is paramount to avoid disruptions and losses during mass production. To address this, the Presto Group offers the advanced Polariscope strain viewer, which utilises the principle of refraction to evaluate preform uniformity effectively.
Before integrating polymer and PET preforms into the production process, manufacturers must ensure their uniformity to prevent defects and delays. The Polariscope strain viewer plays a crucial role in this regard by detecting any strains or irregularities within the preform material.
Utilising Refractive Index for Assessment
The Polariscope strain viewer employs the concept of refraction to assess uniformity. Refractive index refers to how light behaves as it passes through different mediums. For instance, when a pencil is submerged in water, it appears bent due to the difference in the speed of light between air and water. Similarly, when light passes through a preform specimen, variations in the refractive index indicate potential strains or irregularities within the material.
The Polariscope strain viewer operates through a straightforward process, allowing manufacturers to conduct tests efficiently and accurately:
- Specimen Preparation: The preform specimen is securely positioned within the designated area on the instrument, ensuring proper alignment for testing.
- Activation: Upon activation, the Polariscope strain viewer illuminates the specimen uniformly using both CFL and sodium lights. This illumination enables the passage of light through and back the specimen, creating a refractive index for observation.
- Observation: The operator observes the specimen through the wide glass viewing area, assessing any differences in refractive index that may indicate strains or irregularities. The test is conducted at two variable angles (90o and 45o) to analyse refraction variations comprehensively.
Key Features of Polariscope Strain Viewer
The Polariscope strain viewer boasts several features designed to enhance accuracy and ease of use:
- Large Viewing Area: With a 240 x 260 mm glass viewing area, the instrument provides optimal visibility for strain assessment with the naked eye.
- Dual Light Sources: The inclusion of CFL and sodium lights ensures clear and uniform illumination, facilitating accurate refractive index evaluation.
- Two Viewing Angles: Testing at two angles enhances accuracy by ensuring uniform light distribution around the specimen, minimising discrepancies in test results.
- User-Friendly Controls: The instrument features minimal controls, enabling operators to navigate the device effortlessly and conduct tests with precision.
