Krauss Maffei, represented in Oceania by HBM Packaging & Plastics Technologies , have developed a solution for the fabrication of automotive interior acoustic panels.

Normally, these kinds of applications are produced by a RPM spraying process. In this instance the acoustic properties were transferred into an injection moulding process, using the Krauss Maffei IMC (Injection Moulder Compounder) technology, which resulted in material cost savings.

The team at Krauss Maffei designed different mixing and plasticising zones for the twin screw compounding extruder to produce two different sound deadening compounded solutions to meet the acoustic requirements of the customers’ diesel and petrol variants of the same vehicle.

The IMC compounder unit is fitted with a seven head Gravimetric dosing unit that delivers the precise amount of raw materials required for the application. The IMC compounder unit together with the continuous material processing of the IMC, the system is able to produce a constant product quality, when processing barite, an acoustic effective filler.

The customer was satisfied with the IMC systems capability and placed three consecutive orders for IMC machines. Krauss Maffei worked with customers to develop customised solutions, which resulted in cost savings.
