Cost: $1,200 USD
Online Registration
CEU's: 1.6
Instructor: Mr. Terry Chapin

Course Overview

This seminar covers a broad range of topics that are fundamental to the design of rubber molds. Each topic covered includes some basic well known aspects of rubber mold design and also touches on some lesser known rubber mold design techniques and concepts. The novice rubber mold designer will be overwhelmed with useful design information and the seasoned practitioner will find plenty of valuable bits of information well worth the day.
