R.R. single screw extruders are featured by Efficient Process Technique to achieve outstanding Melt Homogenity with a capability to process a wide spectrum of different formulations. High throughput, Low and homogenous melt temperatures for quality extrudate meeting all international Standards are the inherited features.

• Next generation barrier screws with longer L/D (33/36/40 D) are standard for Polyoleophynes (PE–100/125) and an option of other Polymers
• Accurate control of the melt conditions, homogeneous temperatures and Pressures without variation, serging & low thermal stresses
• Highly efficient Temperature controls for Grooved feed bush
• Consistent throughput for all screws speeds
• The Drive motor and the Gearbox can be Directly coupled or Belt driven as per Torque requirement to achieve the optimum efficiency to reduce the power consumption per unit output
• The screws and barrels are normally supplied in Nitrided steel. Bimettalic high wear resistant barrels can be supplied for high speed extruders

R.R. supplies extruder heads with Spiral Distributor designed by means of World class Computer Aided Design Systems for the Dimensioning of the flow channels. The possibility to obtain a perfect melt distribution at Low

Extrusion Pressures ensures the control of the melt temperatures and consequently to keep unchanged the mechanical properties of the Extruded Thermoplastics.

The vacuum tanks are normally fabricated in S.S./ M.S.
