Time: 8:00 AM - 5:00 PM
Location: Akron Polymer Training Center, Akron, OH 44325-5404, U.S.A.
Cost: $875 USD
Online Registration
CEU's: 1.6
Instructor: Mr. Adam Dreiblatt

Course Overview

This two-day seminar focuses on the application of intermeshing co-rotating extruders in compounding applications. Training is directed towards machine operators, process engineers and supervisors, as well as product development scientists in both research and manufacturing environments. Participants are reminded that the goal of compounding is to produce properties, not pellets. The goal of this seminar is to explain how twin-screw extruders create properties.

Interactions between screw design, raw materials and process parameters are presented in such a way that both experienced users and novices will benefit. Common unit operations are explained in practical terms with no prior knowledge or experience required. Upon completion of the training, participants will return to the workplace armed with techniques to improve quality, production rate and yield.

Instructor Biography:

Mr. Adam Dreiblatt has over thirty five years of experience with twin-screw extrusion as a consultant, teacher and practitioner. His hands-on experience processing a wide variety of materials across diverse industries and extruder platforms provides him with unique capabilities to develop, optimize, scale-up and troubleshoot most any extrusion process.

His employment history is as follows:

CPM Century Extrusion, Traverse City, Michigan, 2007 to present. Director of Process Technology for one of the leading suppliers of compounding extruders and replacement part, providing technical support to sales organization and customer base as well as technical support for sister company Ruiya Extrusion in Nanjing, China.

Extrusioneering International, Randolph, New Jersey, 1994 to 2007. Founder of consulting organization for twin-screw extrusion, providing training and simulation software. Specialized in implementation of extrusion technology within the pharmaceutical industry. Developed training seminars and workshops for the Society of Plastics Engineers (SPE).

Novon Products Group, Division of Warner Lambert, Morris Plains, New Jersey, 1990 to 1994. Director of Manufacturing Technology. Developed compounding technology for the first company to commercialize starch-based biodegradable polymers.

Werner & Pfleiderer Corporation (now known as Coperion), Ramsey, New Jersey, 1981 to 1990. Manager of Applications Development, responsible for developing novel applications for twin-screw extruders outside of traditional markets.

Seminar Program - Day One:

Twin-Screw Extruder Design:

  • Introduce concepts responsible for creating properties on co-rotating twin screw extruders
    • Degree-of-fill, shear rate, residence time/residence time distribution, heat transfer
    • Dispersive vs. distributive mixing
  • Influence of extruder configuration on compounding performance
    • How machine design impacts mixing (e.g. d0/di, co versus counter rotation, etc.)
    • What is optimum extruder configuration?

Process Design:

  • Description of unit operations: feeding, melting, mixing, venting, pressurization
  • Introduction of the process model - role of specific energy
  • Interaction of process parameters
  • Process optimization

Seminar Program - Day Two:

The "Art" of Screw Design:

  • Functional description of the working principles for each element type (conveying, mixing)
  • Overview of available screw element designs
  • Characterization of dispersive and distributive mixing elements
  • Selection of the optimum screw type for each of the unit operations

Best Practices:

  • Documentation
  • Start-up, Operation, Shut-down, Purging
  • Screw assembly/disassembly
  • Preventive Maintenance
  • Safety

Process Troubleshooting:

  • Diagnosis of compounding instabilities with respect to
    • Consistency (i.e. within-lot)
    • Reproducibility (i.e. lot-to-lot)

Bring your current processing problems or screw configuration questions to discuss privately with the instructor…this alone can justify the seminar fees!

Participants will return to the workplace prepared to design and optimize screw configurations, as well as develop operating conditions to meet compound specifications.
