    The Rubber Division is holding an Elastomer Molding Technology course, instructed by John Sommer, at its office on August 16. This seminar describes and compares important molding methods (compression, transfer and injection) for thermoseting elastomers (TSEs) with methods (injection and blow) for thermoplastic elastomers (TPEs). Injection molding is emphasized because it is the major molding method common to both elastomers. Injection molding machines and their characteristics will also be described and compared. Finally, there will be a limited description of mold design for TSEs and TPEs. This introductory course will benefit people involved in molding both types of elastomers, especially those transitioning from molding of one type of elastomer to another. Attendees with primarily a materials-related background will improve their understanding of molding processes and the effect of mold design on molded products. Process and design managers will better understand the effect and importance of these factors on the overall molding operation. Attendees will improve their understanding of molding behavior of TSEs and TPEs and thus improve and better control their elastomer molding operations. The interdisciplinary approach used will assist them in understanding molding as an integrated operation consisting of materials, processes and design. The book “Elastomer Molding Technology,” authored by Sommer, will be distributed and used in conjunction with the seminar.
