Training

On site training for sandwich panel production lines

 

Training conceptMOUSSE-POLYURETHANE1-1024x422

 

Having visited and realized expertise on over fifty production lines of sandwich panels in the world, we have seen that there are many gaps in terms of training. With a wealth of experience in this field, we offer training on your production site into two parts.

The basics of polyurethane chemistry and the production line.

Highly detailed, this training takes place in the meeting room with video projection and visits to the production line to create a relationship between your process and the theoretical ideal process. A 100-page guide is provided along with training and accompany you throughout your career.
