Latest technology for high quality composite parts

All our in-house composite parts are made with vacuum infusion technology. Therefore every part has its own mould. Stronger composite laminates, the high repeatability and consistency between parts are just a few advantages compared to open moulding technology.

The preliminary work to the vacuum infusion procedure includes: Cutting of the carbon fibres + optional required sandwich materials and – depending on the part, different flow additive fabrics. Before the infusion process starts, all the material is carefully placed in the mould. The whole material is sealed by a vacuum film. If everything is ready the actual infusion process can start. For this, the assembly is connected to a resin reservoir on one end and to a vacuum pump on the other end. While the air is then being sucked out the resin is flowing into the part. Finally, when the whole part is completely filled up, the in- and outlets are getting closed and the vacuum is hold until the resin is cured.

Vacuum infusion is a technology to produce CFK parts. means sucking resin into the fibre material by applying vacuum. Fibre materials (1) are cutted into certrain shapes and inserted in dry conditions into tools or moulds. Flow mesh is applied (2) on the component.  Resin is sucked in into resin-feed tubes (3) via vacuum tubes, connected to a vacuum pump.  The whole component is sealed in the mould with vaccum bagging film (4) and seal with so called tacky tape (5).
