Surface Strain Viewers

Presto supplies the high quality of Surface Strain Viewers to view the strains on PET bottles. The machine helps to observe the flaws and faults on transparent bottles or preforms. The device is a good quality checker improving the quality of PET and Preforms. The instrument is available in Delux Model and Computerized Model. The operating principal of machine is that any change in the refractive index of a material shows the presence of strain, and that is responsible for the low quality of the materials.

Presto manufactures and designed both models of surface strain viewers using the best quality of raw materials for durability and correct precision level. There are several sizes available to test the quality of glass and preform surface as required. The device has metallic base painted in autumn gray and blue color. The zinc/chrome plating is provided for the resistance against corrosion. The machine helps to check the quality and transparency of the materials.

The device has a significant role in solving the issue of Photoelasticity, where the refractive index of the material changes where there is uneven strain distribution. Photoelasticity is a big trouble for the manufacturers of PET bottles and plastics. The machine is very helpful to solve the issue. This is the best device that have prolonged service life with a precise testing procedures.
