Makes RTM Easier


The pneumatically operated RI-15 RTM production unit is equipped with Aplicator’s unique continuously adjustable catalyst slave pump that provides a precise resin to catalyst ratio. A static mixer fitted to the injection gun ensures the thorough blending of resin and catalyst is achieved. Superbly designed and engineered, the machine is easy to operate using straightforward controls. For optimum efficiency and versatility the machine, mounted on large rubber wheels, can be moved to wherever required in the production area.



Aplicator’s RI-15 RTM machine uses an air driven dual acting piston pumps for both for resin and catalyst. A single air motor drives the pumps for catalyst and resin on Aplicator’s RI-15 RTM machine. Constructed from stainless steel, the catalyst pump incorporates a pressure gauge and pressure relief valve and is mechanically synchronised with the resin pump. This provides precise and pulse free delivery of catalyst regardless of variations in air supply or resin viscosity. Catalyst volumes are easily adjusted with a handwheel, which changes the stroke length of the catalyst pump. The mixing ratios are continuously variable. Catalyst can be pumped direct from the original container. Resin is usually pumped from a 200-litre drum, but can also be pumped from a 25-litre pail, a bulk container or a fixed storage tank. Both catalyst and resin are thoroughly blended together using a static mixer on the front of the injection gun, which helps minimise waste. The machine is equipped with a unique recirculation system for degassing and functional checks.



Cleaning the injection gun after use is easily carried out using the built-in pneumatically operated solvent pump. Pressing the flush button automatically flushes the gun with a mix of solvent and air. Significant reductions in solvent use save costs, enhance working condition and considerably reduce emissions.


The machine showed on the overleaf might have extra equipment, modifications might have been made since the brochures were printed.
