Unscrewing Molds from Aline Components

At Aline, we offer tapping as part of our value-added services, however, injection molded threads tend to be stronger than tapped threads. For tighter tolerances and smoother, denser molded coatings than those produced by thread-cutting operations, rely on unscrewing mold designs from Aline Components.

Today, many custom plastic parts or components have detailed threads, which make ejecting the mold using knock-off methods virtually impossible. To avoid thread damage, such parts must be unscrewed from the mold. External threads can be centered on the mold parting line or molded in both mold halves. However, because mold halves tend to involved, external threads are prone to parting-line flash or mismatch and require slides or side actions. Internal threads can be on collapsible cores or in unscrewing molds.
