Abstract

A molding apparatus for encapsulating devices and having at least one molding pot wherein the pot has a configured bottom is used. The configured bottom serves as a shearing force against encapuslating material pellets which are pressed into the configured bottom by a plunger. The shearing force increases the fluidizing action of the pellets thereby lowering the viscosity of the encapsulating material so it easily enters cavities provided in the molding assembly and completely fills the cavities and encapsulates the devices without damage to the devices.
