PET preforms are used to create plastic products such as bottles and containers. When manufacturing or purchasing PET preforms, it is essential to conduct a test to verify the quality of the product and pet preform supplies. This video shows ways you can follow to test the quality of PET preforms.
These tests include visual inspection and measuring the weight and thickness of the preforms.
When testing the quality of PET preforms, a visual assessment is the first thing to do. This entails searching for any evident defects or imperfections such as moisture marks, cracks, bubbles, and discoloration. If any of these defects are visible, one should reject that PET preform. They should look for preforms made from PET preforms supplies that have no visible defects.
Another way to test the quality of PET preforms quality is by measuring the weight and thickness of each. Usually, the correct measurements are indicated by the manufacturer. Using a digital scale, one can weigh each preform and compare it to the manufacturer’s standards. Similarly, they can check for the PET preforms’ wall thickness to determine the product’s durability and strength. They should then ensure that the weight and thickness variance does not exceed 0.3mm of the original.
