Course covers rubber extrusion.An integrated technological course on "Rubber extrusion technology" will be held February 21-23 by the University of Wisconsin-Milwaukee at the Center for Continuing Engineering Education in Milwaukee, WI.This course will provide applicable basic information on all aspects of the rubber extrusion process. The course will encompass products ranging from intricate profile extrusions to tires having compositions ranging from a single thermoplastic elastomer 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 multiple dense and cellular compounds coextruded with carriers and reinforcements. Consideration will be given to compound selection, evaluation and processing; equipment needed for pumping, shaping (including die design), curing and monitoring; operating procedures to insure high production rates and quality; and analysis and control of process variation. A section on new technologies will explain how to make extrudates with variable cross-section and composition along their length, to form curved sections and to control screw speed for individual extruders forming laminate laminate, n a thin slice of porcelain or plastic fabricated in a dental lab, which is cemented to the front of the teeth to cover gaps, whiten stained teeth, or reshape chipped or broken teeth. structures. The course will conclude with a troubleshooting guide giving 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 course is said to benefit materials and process engineers, die designers, quality control personnel, supervisors and managers responsible for these functions. It is also said to benefit those responsible for specifying equipment purchases and particularly individuals new to the rubber extrusion industry. Speakers will include James F. Stevenson of Honeywell International and John S. Dick, marketing technical specialist for Alpha Technologies. The course outline will include a discussion on materials, including 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. Primping equipment will be discussed, including screw extruders, ram (preform pre·form tr.v. pre·formed, pre·form·ing, pre·forms 1. To shape or form beforehand. 2. To determine the shape or form of beforehand. n. 1. ) extruders, auxiliary devices, drives and transmissions, and temperature control. Shaping equipment examined will include heads and dies. Downstream equipment described will include continuous vulcanization vulcanization (vŭl'kənəzā`shən), treatment of rubber to give it certain qualities, e.g., strength, elasticity, and resistance to solvents, and to render it impervious to moderate heat and cold. (low pressure) and reinforcement. Instrumentation examined during the course will include an 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, and weight and area sensors. Operations, including extruder dynamics, productivity and quality, and process variation and control will be examined, along with advanced technologies, including changing extrudate shape, switching feed streams, directed flow technology, multicomponent process control and low resistance dies. The final portion of the course will deal with troubleshooting, including an introduction, product geometry, extruder operation and material. The registration fee for this course is $1,090, and includes a notebook, program materials, break refreshments re·fresh·ment n. 1. The act of refreshing or the state of being refreshed. 2. Something, such as food or drink, that refreshes. 3. refreshments A snack or light meal and drinks. and networking lunches. Participants completing the course will receive 1.8 Continuing Education Units continuing education unit (CEU), n educational classes or experiences for licensed dental professionals that extend, update, or renew their knowledge of practices in their field. Some classes may be required for relicensing. . Further information is available from Murali Vedula (414) 227-3121. |
