ABSTRACT:
A high-precision injection-molded form for an inductance coil comprises a cylindrical core formed of a solid mass of plastic or similar material which has a surface of relatively low dimensional precision. A thin plastic layer molded over the surface of the core provides a high precision surface including helical grooves in which the windings of the coil are seated.
