Infusion molding

Resin transfer molding With vacuum assisted RTM, this process can be called infusion molding. RTM usually uses liquid TS plastics that is transferred or injected into an enclosed mold usually at low pressures of about 60 psi (410 kPa) in which reinforcement... 

RTM can also incorporate vacuum to assist plastic melt flow. With vacuum-assisted RTM the process is called infusion molding.300 This process could be identified as a take-off to the Marco process.3...

The vacuum-assisted resin infusion molding (VARIM) process was used for fabricating E- glass/epoxy composites. The VARIM process uses vacuum pressure to remove air from the fabric lay-up before and while the matrix resin is introduced to the fabric reinforcement. The pressure difference between the atmosphere and the vacuum is the driving force for infusion of the resin into the lay-up. Once the setup was laid up and completely vacuumed as...
