Twin Screw Extrusion: Troubleshooting Compounding Challenges

On-Demand Course

Recorded on Sep 21, 2022

Troubleshoot your compounding issues (low productivity rate, contaminants, melt fracture...) with twin-screw extruders by knowing how to adjust processing parameters as per your material or batch-size.

Expert Luis Roca will help you correlate compounding instabilities with the interactions between extruder configuration, process parameters and response variables (residence time, specific mechanical energy).

Why should you view this course?

Twin-screw extruder has been the equipment of choice for a long time.  However, compounders still face processing issues (low productivity rate, 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… Join this course and :

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

    • Co-rotating Twin screw extruders (Co-TSE) characteristics
    • Influence of extruder configuration (types, geometry, size, throughput)
    • Extrusion Science & Rheology Principles

  2. Compounding Design Process

  3. Selection of Screws (design/profile)based on the desired properties and end-use

  4. 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)

  5. Troubleshooting Compounding instabilities (melt-fracture, surging...)

Excellent! It gave good tips that apply to any extrusion effort.

Andrew Ortquist , from Uponor

Had some interesting points and new metrics to explore.

Hneine , from Atarfil

Course gives a very good overview of TSE parameters and variables and how they are related to each other.

Zeevenhoven , from Sappi Global

VERY GOOD ! For someone who is new, or someone who has experience, this helps to tie in the physical science behind plastics & extrusion.

Charles S. , from TRINSEO

Good overall fundamentals of compounding. Very good review for our technicians. Enough details without getting lost in the weeds.
