Barrel Insulation Blankets

Save Money on Heat Loss!

Barrel Insulation Blanket System on Twin Screw Barrel


Off-the-Shelf Insulation System (Modular by Design)

Barrel Blankets can be used on any brand injection, extrusion or blow molding machine.  Their primary use lies in saving money by insulating the barrel from heat loss.  This in turn requires the heater bands to cycle less and to lower electricity bills.  

Additional benefits are: Increased heater band life, Increased safety when working on or around the machines and the Increased aesthetic appearance of your machines.

• Adjustable Closure System Insures the Best Fit
• Overlapping Cuff for Maximum Heat Retention
• Maximum Personal Protection
• Typical Payback in 6 Months
  (Based on 24-hours per day, 5 days per week, and paying 5 per KWH.)

A simple system to insulate most injection, extrusion and blow molding machines. Simply measure the outside diameter or circumference of the heater bands and the distance between thermocouples (this is critical). You can utilize a series of insulators to insulate the desired width, for instance, use two 4" blankets to insulate an 8" width.

Packaging:  Sold individually.
