Category: Twin Screw Extruders
Available both in manual as well as fully computerized version with LCD touch screen controls
The MicroScientific table top 16 mm co-rotating twin screw extruders are made with a complete modular build up of the clam shell barrel, where each barrel section have a length of 4 D or 64 mm. This twin screw extruder is available with up to a 52 L/D length and with drive power of 2.2 KW. The modular Clam Shell Barrel is made of through hardened tool steel which has been hardened to 60 HRC and then nitrided to give a surface hardness of around 70 HRC for optimum wear resistance. The standard extruder has a temperature range of up to 400ºC
The screws are built up from individual single elements mounted on hexagonal hardened shafts. Each individual kneading elements is supplied in many angles to enable optimum variations in screw configurations. The screw components are made from high grade tool steel which is through hardened but made with a slightly softer hardness than the barrel to ensure optimum life time for both elements and barrel. As with our larger twin this small bench top version is also available with High Wear resistant elements made from HIP steel grades from Crucible, USA. In addition we can offer two versions of acid resistant elements where the highest resistant types are made from Inconel steel. And with this version, the screw shafts as well as the die is made from Inconel and the same goes for plugs for side feeders and vent openings on the barrel.
The whole clam shell barrel assembly is split in the center and can be easily swung open after loosening the barrel bolts. This gives easy access to the screws for cleaning or changing of screw elements and/or barrel inserts as well as to observe the melt and compounding characteristics of the polymer being processed.
