By incorporating programmable logic controls in the fully automatic production system, the MegajectTM RTM-Pro offers many standard features unavailable on other models. Automatic functions are stored and easily accessed through the touch-sensitive display, which provides full control of the injection and flushing cycles. All of the machines operational features are pre-programmable and monitored. The MegajectTM RTM-Pro ensures accurate repeatability of the moulding process and the capability to interface with other production equipment such as an automatic press or manipulator.
Specification & Standard Features
- Automatic Controls, featuring up to 30 individual pre-programmable moulding menus, each with the following variables; injection volume, injection flow; injection pressure; resin temperature; catalyst start and finish percentages.
- Turbo Autosprue® interface & post injection mix-head & Autosprue air-purge, flush & drying cycle.
- Precision fluid pumps, guaranteeing accurate output between 150 gm/min & 12 kg/min.
- Resin/Catalyst pump system with adjustable ratio between 200:1 and 22:1 (automatic adjustment with PCR).
- In-built 20 ltr. catalyst container with non-intrusive level sensing.
- In-built 20 ltr. Non-pressurised polypropylene solvent tank SP3. with unique submersible solvent pump & non-intrusive level sensing.
- Compact injection head with automatic control of resin & catalyst recirculation and low post-injection mix wastage (38 cc).
- Mould Pressure Guard (MPG) providing accurate injection pressure control.
- Full colour graphical touch-sensitive display screen providing readjustment of machine settings in each menu.
- Multi-level user interface with password protection.
- Catalyst flow/Injection pressure monitoring and parameter reading.
- Multi-channel PID control loop for resin & mould temperature monitoring, where applicable.
- Portable & lockable combined enclosures for controls (IP65) & pump assemblies, mounted on powder-coated steel frame.
- Optional data acquisition and press input/output connections.
- Now available pre-selection and programmable flow control. If pre-selected flow level results in pressure increase beyond pre-selected pressure limit immediate intelligent override control provides safe injection pressure and optimisation of mould fill.
Optional Features

Additional technical information:
- Controls: OMRON CQM1 PLC and NT30C MMI
- Software developed by Plastech T.T.
- All fluid valves air-actuated with position sensors
Progressive Catalysation
A unique feature of Plastech's Megaject RTM-Pro. The Progressive Catalyst Ratio system (PCR) can be programmed to adjust the catalyst percentage during injection, using auto-controlled synchronised servomotors to position the pump along its slave arm. PCR ensures a more linear cure for large or complex mouldings and will reduce gel wait time. All catalyst adjustment is made through the touch-screen, totally eliminating the need for manual adjustment. Upon selection of a preset injection recipe the catalyst pump moves to its start point automatically.
