Microporous Insulation Production Process

Custom, Automated System for Fibers

Spec Engineering designed a system that vacuum conveys lightweight material (4 pcf) and minor ingredients to a mixer for distribution and separation of fibers. Finished material conveys to a product storage bin. Screw auger system and custom gain-in-weight scale system filled bags of finished material. An automatic control system was implemented for conveying, mix cycles, and accurate feeding of finished product.

Project Highlights:


  • The fully automated process is initiated by operator interface HMI with system display status.
  • Vacuum conveyor operator by compressed air eliminated excess motor loads required for the operation.
  • Central dust collector to pull clouds of lightweight dusty material away from operators and control nuisance dust for cleaning.
  • Complete turnkey system including integration and implementation supervision services.
  • Equipment included: bag dump station, vacuum conveyor with discharge hopper, mixer, storage hopper, gain-in-weight feeder, butterfly valve, dust collection unit, dust collection piping and hoods, and controls system
