Automotive Plants | Dash Insulator and Carpets

Dash insulator and carpets are used to reduce engine and road noise into the car interior cabin.

A typical dash insulator or carpet system consists of a steel panel (vehicle body panel), a porous decoupler and a heavy layer in the form of sandwich construction. To make these parts, Cannon has developed two different production systems:

RRIM and BackFoaming

Heavy Layer PUR is a two components PU resin which is heavily filled with Barite especially in Polyol component, and applied onto a surface through a spray or a closed-mould injection (RRIM) process.

FPL SR

L shaped high laminarity and long stroke mixing head

A-Compact

Customizable all in one iconic dosing unit

Forming Lines and Back Foaming

A well-mixed liquid PU is applied into the mould, in order to be to be moulded as a sheet and subsequently glued onto the substrate. This last can be a fabric or even a heavy layer combined material. The PU back foaming can be realized by open mould pouring (assisted by robotic system) or closed mould injection (with multi-mixing heads on different mold carriers). For this process, Cannon provides:
