6.1 High-performance molds

High-performance molds are used to produce objects that need to be injected, cooled and demolded quickly. This calls for thin walls, adapted geometric shapes and low-viscosity materials.

The press must be able to laminate at the right speed, and open and eject parts quickly and accurately. Press idle times, sometimes measured by the idle cycle, must also be optimal (see [AM 3672] ). A demolding control system, such as detection of the presence...
