Seattle, WA, USA--(Jobwerx)--AZDEL Inc., Lynchburg, Va., has announced that it is currently evaluating the potential advantages of the Cage System®, an innovative, high-speed composite molding technology developed by the RocTool Company of France, for use with its own AZDEL* composite materials. According to Ken Forden, president AZDEL, Inc: “We are working in conjunction with RocTool to investigate the use of the Cage System for the production of composites with a class A surface finish.”

The Cage System allows an instantaneous heating of the mold surface only, the rest of the mold remains cold. The technique to achieve this involves passing an electrical current over the surface of the mold by means of inductors that are placed around it to form a cage. The mold cavity surface is heated within seconds, and it is possible to use high temperatures - up to about 400 °C - and to precisely manage temperature thresholds, even using spot heating.

This high level of localized control helps enable a considerable reduction in production cycle times and potentially therefore a reduction in the cost of manufacturing composite parts making it an excellent candidate for medium-run and mass production applications.

Furthermore, the Cage System process offers a truly generic solution that can be adapted to all types of composites, as the heating power is applied at the mold surface only. With the heating by Joule effect principally taking place within the material itself, the mold can be rapidly cooled using a simple system of circulating water. Moreover, the Cage System technology is compatible with standard compression-molding machines and requires only the addition of an induction generator and cooling unit. However, a process-specific mold, with integrated induction heating and water-cooling system is necessary.

The potential advantages of molding composites using the Cage System are:
- Reduced cycle time
- higher production rates
- potential for class A surface finish composite sheet
- possibility for heating threshold control and in-mold cooling of the material
- lower energy consumption

Advantages that might open the way for composites to enter many applications from which they have previously been excluded on the basis of too high cost or too low aesthetic value in the finished part.

The company's composite customers are provided with support in design, testing, molding and prototyping to achieve excellent performance and weight reduction in automotive applications.
