Pressure and Vacuum Control

Pressure and vacuum control governs the compaction, air removal, and resin distribution during the glassing process. Through controlled pressure systems or vacuum lamination, shapers ensure uniform resin saturation and mechanical integrity across each fiber layer. Proper vacuum levels reduce weight, voids, and curing inconsistencies, while excessive pressure can distort fiber alignment and flex response.
Shapers refine pressure and vacuum control through calibrated bagging techniques, leak testing, and cycle timing that maintain lamination precision, structural stability, and flex efficiency.
