Pelletizing extruder RD-M40

for thermosetting polymerplanetary

The RD-M40 is a next-generation high-flow and medium weight pellet extruder. It was designed to 3D print components as fast and cost-effective as possible. It can be combined with robots or CNC machines. RD-M40 is able to output up to 40kg of material per hour. WATER COOLING - HOT ENVIRONMENT READY The RD-M40 is able to operate in any environmental condition. The water-cooling loop keeps the whole system (motor, screw shank, reducer and feeding zone) at a constant temperature. 4 ZONE HEATING BARREL CONTROL The quadruple heat zone design helps to keep the polymer at a constant temperature. The feeding section receives cold pellets and generates more heat to melt them. Then, the compression zone stabilizes the polymer at a precise temperature ensuring the plastification process (all the solid pellets turn into a molten status). Finally, the metering heater ensures an even flow. MULTIPLE NOZZLE SIZE RD-M40 can be used with large nozzles from 3.00mm up to 12.00mm. They can also be customized. CUSTOMIZED EXTRUSION SCREW The bimetallic customized screw design is optimized for high-resolution 3D printing. Two tapered bearings, which support the screw, allow a low friction rotation, a bore centering of the screw in the barrel and can handle the whole high axial force required to extrude in high-speed and pressure conditions. MELTING ZONE SENSOR The temperature sensors are placed only 0,5 mm away from the molten polymer. Readings are reliable and accurate. PRECISE TEMPERATURE CONTROL The four K-type thermocouple sensors are class 1, high precision sensors. The circuit has been designed to use the best resolution between 20°C and 500°C.
