Flying Knives

The interest in large, shallow plastic components has grown world-wide. Kautex Maschinenbau has recognized this market demand and developed a process that has attracted attention because of its cost-effective manufacturing and levels of quality that are unprecedented in this segment.

Compared to conventional processes, where the extruded parison is infalted to the required diameter using support air, this patented process uses special spreader pins to spread the parison over its entire length before molding. 

Before the mold is released, the parison is cut open laterally by "flying knives" so that the spreader pins can retract to release the article.
