Abstract: A device for simultaneously encapsulating a number of electronic components is provided with a locking mechanism in which a molding cycle has two phases, i.e. in a first transfer phase, during which plungers for injecting molten resin into encapsulation cavities are locked and driven at a high, controlled speed, followed by a second curing phase, during which the plungers are spring-loaded, unlocked, and stationary, and are subject to the same maximum pressure of the transfer phase. In this way damage to the products is prevented, while the cycle time is reduced and the products obtained have an even and smooth appearance.

Abstract: A blank is formed out of plasticizable, heated plastic by means of an extruding-type material supply head. A somewhat lenticular profiling of the blank is obtained by appropriately controlling a closing member of the material supply head, which is built as a valve cone. When the closing member is closed off against the lower edge of a tube part of the material supply head, the blank is pinched off from the material supply. A flow of air emerging from a ring nozzle serves to ensure complete severance of the blank from the material supply head. After that has been accomplished, the blank enters an open shaping cavity of a die by free fall. By further movement of the die, which is located on a rotary table, the die removes itself from the permanently located material supply head, so that the blank lying in the cavity can be pressed into a molded article by a stamp. Cooling off too much in certain locations on the blank is prevented by the free fall of the blank into the shaping cavity.
