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.
