Stress Viewer

The penetrating stress polarizer is a non-destructive qualitative observation measurement device, which uses the birefringence property of the plastic molecular structure under the action of stress to observe the change of the photoelastic properties of the plastic part. As long as the transparent plastic or light-transmitting product or test piece is placed in the observation window, the white light source can be deflected through the polarizer by the plastic birefringence and photoelastic properties to form visually observable colored stripes. The displayed stripe form and stripe density can observe the degree of residual stress inside the plastic part.

Through the penetrating stress polarizer, the internal residual stress of plastic parts can be quickly and easily detected, and the stress distribution can be further understood. Through professional technical interpretation, feedback, and consulting services, the causes of residual stress can be found early and suitable solutions can be provided. , optimize mold design and plastic product quality.

Stress Polarizer – Features

Instant observation of residual stress distribution

By means of the plastic birefringence and photoelastic properties, the white light source is deflected by the polarizer to form colored stripes. From the displayed stripe form and density, the degree of residual stress inside the plastic part can be observed.

The part with higher stripe density is the area with higher residual stress of the plastic part.
