Abstract

PURPOSE: To obtain an electromagnet that is long-lived, very accurate and cheap, by injection molding thermal plastic resin on a magnetic core or a surface of an aurmature.
CONSTITUTION: Non-magnetic body, thermal plastic resin 4b is injection molded on a surface 4a of an armature while using the surface 4a as a standard. Thus, the guarantee of dimensions by grinding is unnecessary because thickness C is managed in needed value. Life is prolonged because the thermal plastic resin has wear proof. The same applies for a magnetic core 3.
