International Intensive Short Course on POLYMER RHEOLOGY ...



WHO SHOULD ATTEND

This seminar is an excellent overall review of extrusion technology. It is designed for production people, chemists, product and die designers, engineers, scientists, technicians and end users who are involved with plastics extrusion, mixing and compounding, recycling and process equipment design and manufacturing. This seminar has been developed to include cost-effective production and design techniques that can benefit even those with extensive experience. Participants will gain an increased understanding of processing and will learn some of the unique engineering problems associated with polymer extrusion, operation and troubleshooting of process equipment.

GENERAL INFORMATION

REGISTRATION

The number of participants is limited and it is therefore recommended that you register as early as possible. An administrative fee of AUS$50 will be charged for cancellations received one week before the course starts. After this date there will be no refunding of registration fees but full credit can be given for another person from the same company to attend. Substitutions may be made at any time but an advance notice would be appreciated. RMIT Rheology and Materials Processing Centre will not be responsible for any costs incurred by the attendee in the unlikely event of the seminar being cancelled.
