Process & Lamination

Process guidance for UK composite manufacturers working with open mould production methods. Articles cover spray-up lamination, gelcoat application, hand lay-up technique and the process variables that affect laminate quality — including resin-to-glass ratio, catalyst level, workshop temperature, chop length and gun distance. Surface fault identification and corrective action, roller and consolidation technique, and introductory guidance on resin injection are also addressed. Content is aimed at laminators, process engineers and production supervisors seeking to improve consistency, reduce defect rates and understand the relationship between process control and finished part quality. Articles are relevant to GRP and FRP manufacturing across all seven sectors served by MVP UK & Ireland.
