The production process is as follows:
1. Suitable pieces are cut from a large roll and inserted into a previously manufactured forming tool in a precisely defined sequence and orientation.
2. The blank is packed together with a venting fabric made of felt-like material in a temperature-resistant foil bag, which is sealed airtight with a sealing cord. An initial vacuum is then applied. This presses the fibers into the mould.
3. The component is heated in a type of oven (autoclave) with overpressure until the resin system has hardened.
4. After the cooling phase, the temperature-resistant film bag is removed from the autoclave, the carbon fiber part is released from the mold and prepared for the next processing steps.
5. A robot then mills out the final shape.
6. The parts are then sent for pre-grinding. They are then provided with a sticker and painted. This process is repeated if necessary to achieve the highest possible quality.
With the exception of milling, all production steps are carried out by hand and are therefore very time-consuming. This is what makes a RONAL accessory made of carbon so high-quality and unique.
Incidentally, this technology is also used in Formula 1!
