Hot wet-press process

An alternative process to the vacuum injection process is being developed by using the known so called wet-press process. The wet-press process has the disadvantage of a long hardening time. To improve this by using hot hardening for the product's top layer, is the main new research factor in this project. It would result in a new hot wet-press process which in turn would give the possibility to produce large parts or products more economically. By improving the quality of the top layer and the filling material of the product a shorter production time, but combined with the advantages of the wet-press and injection process, should result in good market acceptance for the final product.

The project was finished with the prototype of a production facility running. A production cycle takes 6 minutes per part from injection to getting the finished part out of the production form.
Considerable work is still required to achieve large scale series production. Exploitation of this new technology should be possible in the automotive industry and in the sanitory sector (particularly kitchen sinks).
