Two types of CRP co-rotating twin screw extruder gearbox

\n\n\n\n

Transcyko manufactures two types of CRP co-rotating twin screw extruder gearboxes, CRPA and CRPB, which are designed to provide different torque densities. Both CRPA and CRPB twin screw extruder gearboxes feature high power density, precision helical bevel gears that deliver synchronised, high-torque power transmission simultaneously to both screws. 

\n\n\n\n\n\n\n\n

Our twin screw extruder gearboxes maintain precise speed ratios even under continuous heavy load. This is of critical importance for plastic and rubber extrusion lines, because even minor variations in screw speed results in imperfect mixing and inconsistent flow.  Transcyko CRP co-rotating twin screw extruder gearboxes are included in our comprehensive range of rubber extruder gearboxes.

Precision power transmission for heavy duty rubber & plastic extrusion

\n\n\n\n

The co-rotating twin screw configuration gives you precision power transmission as both screws turn in the same direction at identical speeds. This makes Transcyko CRPA and CRPB the perfect choice for heavy duty and demanding rubber and plastic extrusion, delivering the consistent intermeshing that makes CRP gearboxes ideal for compounding, mixing, and reactive extrusion.
