Introduction to Injection Molding: The five essential elements – 1 day seminar

This course introduces the five essential elements of Injection Molding. They are plastic part design, the plastic material, the mold and the mold design, the molding machine and the molding process. Often it is thought that molded parts are not molded to the required quality because the molding process was not optimized. Process optimization plays a very important role. However, it is only one of the five elements. The course will explain the basics of each element and how each of them contributes and influences the final product. Common defects in molded parts and their possible solutions will be discussed. Several examples of failed parts and unoptimized designs will be presented. The class will have a live demo session of a molding machine molding parts, an open cold and hot runner mold, a dryer, moisture analyzer and will be open to any requests of the attendees.
