HENNECKE MACHINERY INTRODUCES INNOVATIVE TECHNOLOGY FOR FOAM-IN-PLACE REFRIGERATOR DOOR PRODUCTION
14 October 2002 - Bayer MaterialScience AG

Hennecke Machinery will introduce the company's new RotaMat DDP (Double Door Platen) System, a multi-fixture metering system that offers manufacturers the ability to foam two refrigerator doors simultaneously, while realizing other production benefits.

David Hanne, Account Manager with Bayer Corporation's subsidiary Hennecke Machinery, and Beatriz Geiger, Project/Sales Manager, Hennecke GmbH, will present a paper entitled Innovative Technology For 'New' Foam-In-Place Refrigerator Door Production Wednesday morning at the Alliance for the Polyurethanes Industry (API) Polyurethanes Conference 2002 here.

The authors will explain the cost effectiveness of the RotaMat DDP system, including its unparalleled flexibility to facilitate automatic mold changes, its ability to produce two refrigerator doors simultaneously, its advanced electronics, small footprint, and its blowing agent blending system.

'The appliance market has imposed drastic changes on manufacturers recently,' said Hanne. 'New refrigerator cabinets have contour doors and many shelf combinations. Compartments have changed in size, shape and number. These changes present special challenges for manufacturers. They have to be able to change molds quicklyto efficiently produce the various models within cycle.'

'These model design changes also have driven other changes that impact the production process, such as new locations for foam injection holes,' said Geiger. 'This demands the repositioning of mixheads on existing production equipment. We at Hennecke have developed a solution for that concern as well.'

'Our RotaMat DDP system utilizes a two-axis servo position device that verifies the location of the injection hole on the door and positions the mixhead in it. A signal from a remote sensor that confirms the correct position of the mixhead then triggers the pour.'

In addition to its cost-effectiveness, the RotaMat DDP system has a small footprint, which frees up manufacturing space, according to the authors.
