Description

Warp testing arrangement

Technical Field

Background

The warping phenomenon is widely existing in pain points of glass fiber reinforced materials, and is mainly caused by the fact that the shrinkage rate of the plastic in the flowing direction is larger than that in the vertical direction in the plastic molding process, so that the warping is caused by different shrinkage rates of the parts in all directions; another main reason is that in the injection molding process, a large internal stress inevitably remains in the interior of the product, and the internal stress also causes the product to warp during the release process.
