Our 2017 masterclass workshop in support of Alan Harper Composites North America was a resounding success. The 34 delegates representing composites moulding companies from Canada, USA and Japan were eager to learn in all aspects of reusable vacuum membrane manufacture and the benefits of the cost saving technology. In fact, the interest was so great the attendees were queuing up to purchase the equipment we used for the class as they were so enthusiastic to start using the system.
