All molded rubber parts have several types of cutters. There are two main processes for blurring parts:
• Cut, reduce
• Spray cut
Block blurring is used for simple rubber molds with a cutting system only on the outside of the part. The hugging machine is removed by rolling the parts in a cup. The process can be enhanced using an actuation medium such as a steel ball, chain or brush.
Deflector cutters are used for more complex parts (eg with excess detail in the inner holes or the lower part). Means for cutting and cutting are steel or polycarbonate pellets.
