Twin Screw Extrusion: Process Optimization

44 Days left to register

Wednesday Sep 6, 2017

Optimize your twin-screw extrusion process by knowing how to adjust processing parameters (screw profile, temp., throughput...) for whatever material you use, whatever the batch-size you have. 


Our expert Luis Roca will help you troubleshoot compounding instabilities, melt-disturbance, surging… by correlating them with the interactions between extruder configuration, process parameters (screw profile, temperature…) and response variables (residence time, specific mechanical energy).

Why should you attend?

Twin-screw extruder has been the equipment of choice for a long time.  However, compounders still face processing challenges (increase productivity rate, minimize contaminants, melt fracture...) due to the new additives/polymers introduced faster every year. Most of these challenges can be avoided if one knows how to adjust processing parameters…


  1. Reach faster desired properties (tensile strength, HDT...) in your materials by wisely adjusting twin screw extrusion parameters (polymer flow rate, screw profile, temp....)

  2. Easily adapt your extrusion to suit new material or batch-size constraints thanks to a better understanding of extrusion science & rheology principles (melt-flow, flow stability…) 

  3. Solve faster compounding instabilities (melt disturbance, surging…) by implementing the tips & tricks from the expert

Who should attend?

R&D Chemists, Engineers working with twin-screw extrusion at Compounders, Masterbatchers, who wish to achieve new performance levels and solve faster problems they regularly encounter.

Course Outline

  3. Compounding Design Process
  4. Selection of Screws (design/profile)based on the desired properties and end-use
  5. Optimization of process parameters
    • Feeding, melting, mixing, venting, pressurization
    • Effect of temperature, pressure and other process parameters
    • Response variables (Melt pressure, Specific Energy, Torque, residence time) & their roles
    • Correlation of Process parameters, response variables and their effect on overall performance (through simulation)
  6. Troubleshooting Compounding instabilities (melt-fracture, surging...)

Excellent! The course outlined the essential elements to TS process optimization.

David C. , from Zoltek Corporation

The course both reinforced current knowledge and provided some new knowledge.

Josef K. , from Champlain Cable Corp

It is a good overview of main parameters to be monitored/controlled during extrusion activities.
