Resin Transfer Molding (RTM) and Vacuum-Assisted RTM (VARTM) Metering, Mixing and Injection Systems

Dispense void-free, accurately metered and mixed epoxies and polyesters into RTM and VARTM molds for superior preform penetration and void-free resin injected parts.

Injecting resin into RTM parts can be as simple as mixing epoxy in one of our Heated Batch Degassing and Mixing Tanks, applying vacuum to deair the mixed resin and then applying dry nitrogen over-pressure to force the air-free mixture into the RTM mold.

To achieve repeatability and consistency in your fully automated RTM or VARTM production process, APT has custom-designed its equipment to instantaneously monitor and control all of your critical process variables. These variables, which you digitally enter at the operator- interface touchscreen, include ratio, independent material temperatures to 500F, vacuum levels in the heating and degassing tanks and inside the mold, plus inside-the-mold mixed resin pressures and mixed resin flowrates. With this level of process control and automation, our customers fill void-free vacuum-assisted preforms on a production basis. They also easily select saved part recipe presets to consistently dispense air-bubble-free resins into RTM or VARTM molds of many different sizes and shapes.

Where your budget allows, we can provide you with state-of-the art resin injection systems with digital PLC and PC control that operate in real-time with digital pressure sensors and mass flowmeters — to track and verify mixed material penetration into preforms. Our systems operate at very low PSIA infusion pressures for Vacuum-Assisted Resin Transfer Molding (VARTM) and at elevated injection pressures from 100 to 500-PSI for closed-mold Resin Transfer Molding (RTM) applications.

If you are at the experimental stage or on a temporary tight budget, we can offer alternative lower-cost RTM and VARTM systems that will help you get your project under way.

Any of our ECS, SRD, SRD-iSeries and HT-Series metering, mixing and dispensing systems can be equipped to operate under the umbrella of RTM resin injection and VARTM resin infusion systems. Our digital SRD and ECS-Series systems provide state-of-the-art monitoring and control of these processes.
