The School of Continuing Education provides non-credit continuing adult education, English as a Second Language, vocational skills, 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 Thermoplastic elastomers (TPE), sometimes referred to as thermoplastic rubbers, are a class of copolymers or a physical mix of polymers (usually a plastic and a rubber) which consist of materials with both thermoplastic and elastomeric properties. 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 A corrective action is a change implemented to address a weakness identified in a management system. Normally corrective actions are instigated in response to a customer complaint, abnormal levels if internal nonconformity, nonconformities identified during an internal audit or . This program is said to benefit teams involved in Six Sigma Not to be confused with Sigma 6.
Six Sigma is a set of practices originally developed by Motorola to systematically improve processes by eliminating defects. A defect is defined as nonconformity of a product or service to its specifications. 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 elastomer (ĭlăs`təmər), substance having to some extent the elastic properties of natural rubber. The term is sometimes used technically to distinguish synthetic rubbers and rubberlike plastics from natural rubber. properties, laboratory tests for extrudability, compound ingredients, and processing and compounding.
Session 2 on pump equipment will discuss the screw extruder, ram (preform pre·form

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 A pressure sensor measures the pressure, typically of gases or fluids. Pressure is an expression of the force required to stop a gas or fluid from expanding, and is usually stated in terms of force per unit area. A pressure sensor generates a signal related to the pressure imposed. , 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 continuing education unit (CEU),
