| Cage System® molding machine |
Sakai Ovex has introduced the patented technology, Cage System® from Roc
Tool, France and molding machines for vertical production of CF fromteasing(opening)
to the final product. Cage System® uses an induction heating system and is
suitable for molding thermoplastic or thermosetting resins with composite materials.
By acquiring this license, Sakai Ovex obtained a “through manufacturing
system” for CF products－teasing(opening,) weaving, impregnation
and molding－ and plans to develop articles for industrial and technical
textile materials, such as for IT equipment, automobiles and the air and space
industries.
Sakai Ovex explained the historical background of the introduction and characteristics
of this system.

▽Historical background
Sakai Ovex planned a vertical production of CF articles from opening to the
final products and their business. They receive permission to use the teasing
(opening) patent of CF from FukuiPrefecture and got a co-patent on weaving with
FukuiPrefecture.
The main manufacturing stages are teasing(opening,) weaving, impregnation
and molding. At present CF related companies are envisaging an improvement of
the impregnation and molding stages. Sakai Ovex also collected the related information
and conducted many trials, and met Roc Tool (Bourget du Lac, Lyon) at the Lyon/Fukui
Local to Local industrial interchange program, three years ago. Then, they exchanged
information with each other on molding technology, and Sakai Ovex decided to
acquire the license for rapid molding technology,Cage System®, and purchased
the molding machine.
Sakai Ovex had already established the technology for manufacturing a multi-axial
layered sheet and preform and installed the apparatus for the production.
1. Characteristics Cage System® is patented technology owned by Roc Tool. This technology
uses induction heating and is suitable for molding thermoplastic or thermosetting
resins with composite materials.
The major characteristics are as follows:
2. Induction heating system with energy saving This system heats only the surface of the metal mold, leading to energy saving,
whereas conventional ones heat almost the whole of the metal mold.
3. Short molding cycle time The heating and cooling times can be shortened, leading to remarkable savings
in molding cycle time, because of localized heating.
4. Strict temperature control This system is suitable for molding thermosetting materials because the operating
temperature can be strictly controlled.
5. Pre-heating is not required This system is suitable for molding thermoplastic materials because no pre-heating
of the preform (composite fabric materials or composite chopped materials) is
required. |
