  • Patent number: 4377548
    Abstract: A large multi-cavity mold is loaded with a plurality of horizontal radially leaded capacitors. The closed mold grips the leads. A top knock-out pin pushes each component body downward a predetermined degree so that all the bodies are left in about the same position within the corresponding mold cavity. A bottom knock-out pin then pushes each component body upward only slightly above the cavity center so that upon its withdrawal, the programmed lead wire stresses cause the bodies to spring back just to the mold cavity center position. Molding resin is then introduced into the cavities. The incidence of show-throughs is greatly reduced.
