New Method of Analyzing Adhesion/Friction in Resin-molded Structures and its Application to Insulated Rods

Abstract

The forces working at the contact interface between the metal and resin of a resin mold, which was made of metal cylinders covered with resin mold, were experimentally investigated. The forces discussed in this paper were modeled by friction force, adhesive force, and contact pressure based on residual stress. A new coefficient for adhesion was introduced by describing adhesion force. Moreover, FEM model of the forces acting on the contact interface was developed. The excellent agreement between the calculated and measured forces in applying the model to the design of an actual industrial product, i.e., an insulated rod, verified its accuracy.
