Best Equipment for Stress Analysis, Transit Testing & Weathering Evaluation

 Modern manufacturing demands precise testing methods to ensure that products remain durable, reliable, and safe throughout their lifecycle. Presto Group provides some of the best testing instruments trusted across packaging, plastics, automotive, and material research industries. This article highlights three essential solutions—the polariscope , vibration table , and UV weathering test chamber —along with the importance of advanced testing instruments in quality assurance. Polariscope for Accurate Stress Inspection The polariscope is a specialized instrument used to detect internal stresses in transparent materials such as PET bottles, acrylic sheets, and glass components. These invisible stresses can compromise product strength and cause cracking or deformation during use. By analyzing birefringence patterns under polarized light, manufacturers can identify defects early and improve container design. This makes the polariscope indispensable for beverage, pharmaceutical, and ...
