Splay (plastics)

From Wikipedia, the free encyclopedia

Splay is a term used in the manufacture of injection molded plastics to refer to off-colored streaking that occurs when moisture is caught in the material feed, or if the material degrades during processing. That degradation creates a gas, which is the cause of splay. If cold material impacts the surface from filling at speed, jetting may appear, which looks very similar to splay.
