Ballotini Profile Extrusion Curing Ovens

Born out of a RAPRA research project, Ballotini vulcanization channels contain a bed of glass beads fluidized by hot air. The combination produces heat transfer rates 5 to 8 times faster than conventional high velocity hot air ovens. This is the curing medium of choice for high speed production of supported EPDM extrusion profiles for the automotive industry. Depending on the profile, line speeds of up to 36m/min (120 ft/min) can be achieved.
KRR Inc. has evolved the design of these ovens to:

  • Minimize maintenance costs
  • Improve energy efficiency
  • Reduce line start-up times by employing advanced control schemes.
