Single Screw Extruder

  • Ideal for production, material testing, new product development and quality control purposes
  • Used in various processes such as compounding, pelletizing, sheet extrusion, pipe extrusion, wire coating and blown film
  • Available in 1 1/2", 2 1/2", 3 1/2", 4 1/2", 6", 8", 10" and 12" diameters
  • A variety of standard and custom-designed screws and barrels are available for various applications
  • hardened alloy steel or bimetallic cast liners for added wear and chemical resistance
  • Rupture disc port protects against excessive pressure build up
  • Reduced root diameters in the venting area allow for efficient single or multi-stage venting
  • Vacuum system with separator on the extruder frame is easily accessed for cleaning and maintenance
  • Screws finished with Stainless steel, Dura-nickel, nitride hardening chrome or plasma coating

Control Systems and Drives

  • The combination barrel top port may be used for venting
  • Control panels incorporate the latest technology: DC ammeters, digital speed indicators, heat zone meters, pressure gauages, melt thermocouples, strip chart recorders, and any other custom instrumentation as required
  • Control and monitoring units are readily accessible and easy to operate, which allows for the process to be monitored at each stage of the production
  • Barrels are divided into heating and cooling zones for greater temperature specificity
  • Heating is derived from resistance heating elements and cooling from the use of air or fluid
  • Temperature of each barrel zone is controlled separately
  • Auto tuning PID temperature controls are standard for each zone, displaying set point, present value and digital amp meter and heater open alarm
  • Drive units: low noise gear reducers with integrate torque distribution, standard AC inverter drives for excellent torque over speed range and DC drive with or without tach feedback are also available
