Water jet cutting for any Caprolon workpiece (Polyamide PA-6) Considering the poor heat conductivity and the considerably low (as compared to metal) melting point of polymers, heat generation must be reduced as much as possible during the cut process. Excessive heat may result in undesirable consequences, including the workpiece being broken, the cutting tool melting, and degradation of working precision. Caprolon water jet cutting technology allows all the above negative consequences to be eliminated.
