Aplicator’s IPR2-8000 is a superbly designed and engineered low-pressure injection machine for successful Resin Transfer Moulding (RTM). Using advanced and proven techniques, the machine is easy and safe to handle with simple controls for straight. straightforward operation. An exact resin to catalyst ratio is provided by Aplicator’s unique steplessly adjustable catalyst slave pump. Internal mixing of resin and catalyst in a static mixer at the injection head, minimises waste during flushing.

OPERATION

Aplicator’s IPR2-8000 machine works with air driven dual-acting piston pump, both for the resin and the catalyst. Manufactured from stainless steel, the catalyst pump incorporates a pressure gauge and pressure relief valve and is synchronised with the resin pump shaft for precise delivery of catalyst. Consequently, it is independent of variations in air supply or material 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 is pumped directly 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. Components are mixed internally in a static mixer at the injection head for thorough blending of the product. Aplicator has used this method of internal mixing of resin and catalyst for many years. This system has proved to be the optimum method of obviating problems that can occur with incomplete mixing. To facilitate degassing and functional checks the machine is additionally equipped with a unique recirculation system for the catalyst and resin.

FLUSHING

Cleaning the injection head after use is easily achieved using the built-in pneumatically operated flushing pump. With no manual handling of potentially hazardous solvents, simply pressing the flush button on the pump, automatically flushes the static mixer on the gun.

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