Cold End

Glass fiber 3D bags

Description

Lose and perfect volume open glass fiber filled into the PE bag
Different sizes and weights of polyethylene bags with insulating fiber inside. Operator pretty simple assembly bag into muffler chamber, after start up of engine, hot gas melts polyethylene bag and lose fiber fill out completely whole chamber.

Advantages of using bags

  • Guaranty weight of insulation per muffler is the same in each one, so noise reduction of each muffler is replicate and controlled
  • Significantly reduced time of muffler production process; labor consuming is lower and reduces costs
  • That is all well environmental solution (no flying fibers, no WAST)
  • Glass fibers absorbs 3-4 times less water then mineral wool - lower corrosion of the muffler
  • Chopped glass fibers are 10-25 times longer then mineral wool what influence on "blow-out" effect
  • There is no "flying" all around fibers on the production line - operators has only contact with polyethylene bag delivered in paper cardboards
