Silicone Elastomers Technology and Fabrication

Receive a comprehensive overview of silicone elastomers, including basic silicone chemistry, types of silicone elastomers, manufacturing processes, fabrication techniques, problem-solving and application areas. With an emphasis on liquid injection molding, learn from a panel of experts in the silicone field, and discuss specific projects of interest.

Featured in this course is a one-day “field trip” to M.R. Mold & Engineering Corp. during which attendees experience all the manufacturing processes involved in producing an actual liquid silicone rubber part including material selection, pump design and operation, tool design considerations, injection molding machine setup and operation, and flow analysis.

This course will be held at the Embassy Suites in Anaheim, Orange, CA. Reserve your room today!

This course can be applied to the following certificates:
Elastomer Technology Certificate
