Course Overview
Course Times: 8:30 am – 11:30 am; break for lunch at 11:30 am until 1 pm; and class will start back at 1 pm until 4 pm (EACH DAY)
This seminar formerly titled Rubber Molding Processes: Principles, Troubleshooting & Mold Design covers a broad range of topics that are fundamental to the design of rubber molds. Each topic covered includes some basic aspects of rubber mold design and also touches on some lesser-known rubber mold design techniques and concepts. Learn the fundamentals of molding rubber mechanical goods and designing their rubber molds with no reference to the molding of tires. Review applicable molding methods with emphasis on compression, transfer and injection processes. This course applies an integrated perspective on rubber molding and design of rubber molds and will cover current principles and techniques in the design of molds and molded part design. This course will allow the attendee to evaluate useful design information and is valuable for beginners and seasoned practitioners.
Information from the books, Elastomer Molding Technology and Rubber Molding Principles, will be used in conjunction with the seminar.

Instructor Biography:
Terry Chapin received his B.S. from Youngstown State University in Youngstown, Ohio in June 1980. He majored in mechanical engineering and minored in math and civil engineering.
After 33 years, he retired from Delphi as a senior materials engineer, working primarily in the area of silicones, elastomer parts and foam products development. He was previously senior rubber technical and cost leader at Delphi, after working as a tool engineer for rubber and plastic molds at the Delphi Packard Division for more than 20 years. He is now working for himself as a consultant and instructor. His new company is Elastomeister, and his position is Rubber Technologist.
Terry has been involved in the rubber industry for more than 30 years, working with rubber companies all over the world. He has held previous engineering positions at Paxson Machine Company, EMCO Wheaton and Commercial Shearing. He holds two U.S. patents. Terry has been an active technical speaker for university level continuing education instruction, rubber conferences and technical in-plant venues for more than 25 years.
