HP-RTM Hydraulic Press Performance characteristics HP-RTM is high-pressure resin transfer molding. It refers to the process of using high pressure to mix and inject resin into a vacuum-tight mold prelaid with fiber reinforcement materials and pre-placed carbon parts, and then obtain composite materials through resin flow filling, impregnation, curing, and demoulding. Application HP-RTM molding process is one of the composite material molding processes that is now widely used in many industries. Compared with the traditional RTM process, its advantages are low cost, short cycle, large batch , and high-quality production (good part surface). It is used in many industries such as automobile manufacturing, shipbuilding, aircraft manufacturing, agricultural machinery, railway transportation, wind power generation, and sporting goods.
