On-Site Sandwich Panel Training

Description:

After visiting and assessing over fifty sandwich panel production lines worldwide, we have identified numerous gaps in training. Drawing upon our extensive experience in this field, we offer a two-part training program at your production site.

Part 1: Fundamentals of polyurethane chemistry and the production line.

This highly detailed training takes place in a meeting room with video projection and includes visits to the production line to establish a connection between your process and the ideal theoretical process.

A 100-page guide is provided along with the training and will accompany you throughout your career.
