Extrusion technology examined.

The University of Wisconsin--Milwaukee will hold a course on "Rubber extrusion technology," February 22-24 at the UWM School of Continuing Education in Milwaukee, WI.

This course is said to provide useful basic information on all aspects of the rubber extrusion process. It encompasses products ranging from intricate profile extrusions to multi-component tire extrusions. Product compositions range from thermoplastic elastomers to natural rubber to multiple dense and cellular compounds coextruded with carriers and reinforcements.

The variety of products, equipment and processing conditions within the rubber extrusion industry will be given a common basis by grouping topics in categories, including compound ingredients, characterization and processing; equipment for pumping, shaping and curing (including die design); instruments for characterizing extrusions on-and off-line; operating characteristics for equipment; procedures to insure high production rates and quality; and process variation and control.

The course will include a troubleshooting guide covering problems, causes and corrective actions. This program is said to benefit teams involved in Six Sigma programs by providing cause and effect relations essential for DOEs, FMEAs, QFDs and other quality procedures.

This course is said to benefit materials and process engineers, die designers, quality control personnel, supervisors and managers responsible for these functions. It is said to enhance the capabilities of those responsible for specifying equipment purchases, and particularly individuals new to the rubber extrusion industry or who have recently been promoted.

Course instructors will be James E Stevenson of Honeywell International and John S. Dick of Alpha Technologies.

Session 1 on materials will examine elastomer properties, laboratory tests for extrudability, compound ingredients, and processing and compounding.

Session 2 on pump equipment will discuss the screw extruder, ram (preform) extruders, auxiliary devices, drives and transmissions, and temperature control.

Session 3 on shaping equipment will examine heads and dies.

Session 4 on downstream equipment will discuss continuous cure (low pressure), batch cure and hose manufacture.

Session 5 on instrumentation will look at the instrumented extrusion line, temperature sensors, pressure sensors, dimension sensors, weight and area sensors, and property sensors.

Session 6 on operations will examine extruder dynamics, productivity and quality, and process variation and control.

Session 7 on advanced technologies will look at changing extrudate shape, switching feed streams, directed flow technology, multi-extruder control and low resistance dies.

Session 8 on troubleshooting will focus on product geometry, extruder operation and compounds.

Participants completing this course will receive 1.8 continuing education units. The fee for the course is $1,290. Further information is available from Murali Vedula (414) 227-3121.
