  • Method of fastening metal part to plastic part
    Patent number: 4106962
    Abstract: A hole is drilled in a metal plate and the plate is then dimpled around the hole after which the plate is positioned against the plastic part. An ultrasonic horn is applied to the dimple area of the plate, the energy from the horn causing the plastic around the dimple to soften and enabling the dimple to be embedded in the plastic, and the plastic material to flow through the hole and to fill the dimple to thereby lock the metal part to the plastic part.
