Non-Contact Heat Sealer for Sheet Molding Compounding

Introduction to Non-Contact Heat Sealing of SMC Films

PolyGroup Inc. has developed a revolutionary and affordable specialized non-contact heat sealing system that eliminates rollers, springs, heat transfer tapes/bands and conventional cartridge heaters commonly used today in the Fiberglass Reinforced Plastics (FRP) Sheet Molding Compounds (SMC) industry.  This new non-contact sealing system uses carefully controlled hot air and fits into the same space reserved for your current seal bar/band system.  The sealing system is useful for both permanent seal and peel-seal SMC barrier films.  It’s the optimal sealing system for consistent lock seal and/or seal-peel every time.

Benefits of our Non-Contact Heat Sealer System

  • Provides precise seal temperature control
  • Improves consistency of peel force
  • Offers significantly broader operating window for a variety of seal layer formulations
  • Reduces process interruptions and the need for constant adjustments
  • Eliminate film and compound paste gumming up seal bars/bands
  • Reduces compound paste blowing out at the edge of film especially for heavy sheet products by using optional built-in fast cooling technology
  • Simplifies maintenance and eliminates constant need for replacement of Teflon coated bars/bands, heaters, springs and actuators
  • Improves ease of operation and machine set-up
  • Reduces operator error and scrap rate
