Resin Transfer Molding (RTM) Process for Composites

1. Semifi nished partCarbon fibers or glass fibers are prepared for the resin transfer molding process.

2. PreformingThe semifinished part is preformed mechanically.

6. Post-curing (optionally)To ensure a full cure, post-curing can be performed (e.g. 1 hour at 150 °C).

5. Injection & curingThe components of the composite matrix resin LOCTITE® MAX series are mixed and injected into the mold.

Reduce weight. Reduce costs. Increase quality.Henkel offers composite solutions for the automotive industry.

7. Surface preparationThe surface of the molded part is prepared for further processing. Henkel provides the ideal solutions for that area.

3. Mold preparationThe mold can be prepared with an external release agent like LOCTITE® Frekote 1C or 2C.

4. Inserting preform into moldThe preformed part is inserted into the prepared mold.

8. BondingThe finished part is assembled into place. Henkel provides the ideal solutions for every bonding application.
