Abstract
A method and apparatus are disclosed for joining a plastic insert or component to a plastic base having a recess therein. The component is provided with integral projections thereon that are in a circular array with the projections being separated circumferentially from one another by spaces. The projections are force-fitted against the plastic base. The plastic of projections is caused to flow circumferentially into the spaces, and the plastic of the base is caused to flow into the spaces where the plastics are melded together. Then the flowed, melded plastics are brought to a solid condition with spaces now filled with solid, melded plastics that interlock the components to the base against rotation relative to one another and to prevent them from being pulled apart. The preferred component is a boss. The boss may be inserted into a recess in the plastic base, and a shoulder on the boss may abut the plastic base and limit the insertion of the boss into the base.
