Albany International said it has been having good success with its Pyropel-brand insulation in helping its customers reduce energy costs and improve mold performance in compression and injection rubber molding applications.
Pyropel was developed specifically to meet the demands of rubber and plastics processors. It is a lightweight and durable polyimide fiberboard with superior insulating products across a broad temperature range.
``Insulating the sides of rubber molds is one of the easiest and most cost-effective things a company can do to reduce energy output and improve mold performance,'' said Gordon Varney, general manager of Albany International's High Performance Materials division.
The firm claimed that existing Pyropel customers had seen up to a 25-percent reduction in energy consumption for its molding operations. The insulation also can help reduce cycle times, increase line speed, and improve worker safety and comfort.
Jason Schrader, a process engineer for Cooper-Standard Automotive Inc. in Auburn, Ind., said his firm uses Pyropel to insulate injection molds. Besides reducing the amount of heat-up time before a mold is ready for production, he said it also has cut down on the number of workers getting burned by accidentally bumping into the mold.
``It's really worked out well,'' Schrader said. ``The prior material we used was not as durable as Pyropel. It really doesn't wear out.''
Albany International also said Pyropel also can prevent heated molds from losing temperature on the edges when outside air is circulating in the plant or electric fans are used near the presses. The firm said this condition can have an adverse effect on defect rates in the mold.
