Automated Resin Transfer Molding (RTM) Production Line

HP-RTM stands for high-pressure resin transfer molding. It refers to the use of high-pressure pressure to mix and inject resin into a vacuum-sealed mold pre-laid with fiber reinforced materials and pre-set carbon parts. After the resin flows to fill the mold, soak, dissolve and demould, the composite material product is obtained. RTM & HP-RTM molding process is one of the composite material molding processes widely used in many industries. RTM, HP-RTM automated production line is used to produce composite structural parts with very high mechanical properties.

RTM production line

As a composite material molding machine supplier, Zhengxi has rich professional skills and designed an RTM & HP RTM automated press system and production line for aerospace and automotive manufacturing applications. It increases molded part productivity and improves process consistency. At present, the RTM & HP RTM production line has been gradually used in new energy vehicle parts, such as battery cases. This fully automated production line can produce 100,000 parts per year.
