Production

Process

Thanks to our expertise in the field of fiber composites, we are familiar with the requirements of various manufacturing processes and guarantee the highest quality.

RTM Process (Resin Transfer Molding)

In the case of RTM, dry fibers are inserted into a pressing tool as a preform. A resin system is then injected under pressure into the closed, airless mold. The fiber layers are impregnated with resin and then cured by temperature.

Process

Insertion of the 3D preform,
closing of the mold

Injection of resin

Compression stroke of the press,
resin hardens

Open press,
remove part

Advantages

High component quality
High reproducibility
High degree of automation possible
Fast cycle times

PCM Process (Prepreg Compression Molding)

In the case of PCM, preformed prepregs that are already impregnated
with resin are cured.

Process

Prepreg cutting and preforming

Pressing the pre-formed semi-finished product

Hot pressing

Open press,
remove part

SMC Process (Sheet Molding Compound)

In the case of SMC, prepregs made from short fibers are also used. The material is cut to size and further processed into the finished part by pressing. Complex molds can be filled and fastening elements inserted into the mold in a single work step.

Process

Cutting of pre-impregnated fabrics or scrims

Preforming and pressing

Shaping and hardening
under heat and pressure

Removing the finished part

Autoklav-Verfahren

Das Autoklavverfahren ist ein hochpräzises Fertigungsverfahren zur Herstellung von faserverstärkten Verbundwerkstoffen wie CFK (carbonfaserverstärkter Kunststoff) oder GFK (glasfaserverstärkter Kunststoff). Es wird vor allem in der Luft- und Raumfahrt, im Automobilbau sowie im Sportgerätebau eingesetzt, wo höchste Materialqualität und Festigkeit gefordert sind. Hergestellt werden Bauteile mit hoher Festigkeit, geringem Gewicht und – durch die porenfreie, gleichmäßige Aushärtung unter kontrollierten Bedingungen von Temperatur, Druck und Vakuum – exzellenter Oberflächenqualität.

Process

Ausplotten der verschiedenen Schichten aus Prepreg

Einbringen der Prepregs in die Form

Laminieren der Prepregs in der Form

Vakumieren der Form in einem temperaturbeständigen Foliensack

Aushärten unter Druck und Hitze im Autoklav

Fertiges Werkstück

Advantages

Hohe Bauteil-Qualität
Komplexe Bauteilgeometrien möglich
Ausgezeichnete mechanische und thermische Eigenschaften
Exakte Reproduzierbarkeit von Bauteilen

IMC Process (In-Mold-Coating)

This is a coating process – a Toray-patented process is also available – for plastics in which the IMC is applied during or after the pressing process. It achieves a high surface quality and thus simplifies the painting process.
