12 mm Table-Top Twin Screw Extruder

The PTSE 12/36 EC is a 12mm 36:1 L/D Stand Alone Table-Top Twin Screw Extruder with CAN-open BUS technology for compounding small quantities of polymers, HME, and scale-up ability to larger Twin Screw Extruders. The drive is 2.4 kW (inverter drive) with a max. torque of 30 Nm and a speed range of 1-600 rpm. The 12mm co-rotating screws are housed in a barrel length of 36:1. The unit is enclosed in a complete stainless steel shroud and includes a 5-zone temperature controller for 4 heating zones and 1 heating die zone.

In addition to the feed opening, there are two additional openings which can be closed or used either as feeding sections or as a venting port. This possibility offers the real advantage of using the extruder with different L/D ratios without having to modify the total length of the barrel or the screws. Usual pellet size of 1.5mm x 1.5mm can be processed or granular / powder materials. The removable barrel liner offers quick cleaning and sterilization. The complete barrel is split horizontally to allow quick access to all parts in contact with the material for rapid cleaning and easy analysis of the extrusion process.

Optional ports can be added per customer specification.
