Pet Preform Strain Viewer

Presto supplies and manufactures the efficient and reliable Pet Preform Strain Viewer to test the quality and transparency of the various industrial products such as PET and Preform bottles. The device works on the operating principle that any variation in the refractive index is caused by the different strain distribution, and this causes to lower transparency of materials. There is various sizes and specification of the instruments as required by the customers or clients.

PET, Preforms and glass materials experience the photoelasticity, means a change in the refractive index of the material. The uneven distribution of strain throughout the material causes the change in refractive index. This is the major problem of the PET and glass industries because photoelasticity is the reason of imperfection.

Presto pet preform strain viewer is available in two models; DX and computerized. The high quality of materials is used to manufacture the instruments so that an extended service and testing procedures could be enabled. Presto believes in perfection in each area, and therefore, zinc and chrome plating is provided against corrosion. Presto provides the machine with the instruction manual to enable the users for a better understanding of each part and function. The conformance certificate is also provided that is traceable to NABL approved laboratories.
