Making Properties and Profits: Twin Screw Extrusion Seminar

Cost: $650.00 USD
Online Registration
CEU's: 2.5
Instructor: Dr. Sylvain Seif

Course Overview

This course 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. Usage of mineral fillers and processing aids to increase throughput and reduce costs will also be elucidated.

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

Instructor Biography:

Dr. Sylvain Seif has over 15 years of industrial R&D experience in Polymer Engineering, spanning several different areas in the field, and over 12 years of academic teaching experience. He completed a BS in Mechanical Polymer Engineering in 2005 followed by a PhD in Polymer Engineering degree in 2009 from The University of Akron in OH, USA. After graduation, he joined INDEVCO Group, a multinational packaging and consumer goods firm, starting up an R&D Center called “PACT”- Polymer Application Center for Technology- for the entire flexible packaging and compounding divisions of INDEVCO, which consists of 10 manufacturing facilities spread across the globe. He has also taught several engineering courses at the university level, and started R&D collaborations with 5 different universities, refereeing over 30 Masters and Final Year Projects, and being a jury member on all these projects. In 2017, as Senior Technical and R&D Expert at PACT, he helped the INDEVCO R&D Center attain ISO 17025 accreditation for lab testing.

Since 2022, Dr. Seif has been working at an environmentally conscious start-up company, Novoloop, in California, managing the polymer processing lab; having expertise in operating the twin screw compounder, injection molding and co-extrusion cast film machines. Here, he optimized the processing and properties of various durometer TPUs, whereby the polyester polyols are derived from PE recycled waste. He is also very familiar with structure-processing-properties relationships of polymers and their composites, with a strong know-how in lab testing methods for mechanical, rheological, thermal and physical properties. Moreover, Dr. Seif has over 10 academic publications and 3 patents in the polymer field, and has a strong passion for teaching and doing research and development in sustainable solutions.
