Critical shutoff refers to how tooling components close off against each other during the molding cycle. These shutoffs determine how complex a part can be manufactured and also determine the quality level of the part. Applications include two-shot molding, insert-molding (catheters, gold-plated components, stainless steel tubes, circuit boards, magnets, molded components, etc.), contoured parting lines, interchangeable tooling, spring loaded shutoffs, and telescoping shutoffs. To this day, customers gravitate to Advanced because of the creativity of the tooling approaches to make complex parts. Advanced was founded and owned by a toolmaker after all!
