Plastic Fabrication

One-Day Plastics Welding Course

"The Course was great. Exactly what my staff and I needed to fast track our understanding of the Plastic Welding technology. I am much more comfortable with my knowledge of the process and realizing my colleague was a bit of a natural at it helps me know we will be successful. Thanks to Matt for his patience teaching us and to Anthony for arranging the course for us." -Brandon Jewitt, General Manager, On the Water Designs
