ELECTROCONDUCTIVE INJECTION MOLDING METHOD OF RESIN PART

摘要

PURPOSE:To form an electroconductive layer of good adherence entirely on a surface and a back of a molded resin parts readily, by applying an electroconductive substance in advance to a surface of a mold cavity. CONSTITUTION:A wax releasing agent 3 is applied on a cavity surface of an upper mold 1 and a lower mold 2 and an electroconductive liquid covering material (a mixture of carbon fiber, metal powder etc. and the same resin as a molding resin) 4 is sprayed. A resin is injected in the mold and a resin molded product 6 is molded. The releasing agent 3 is washed and removed. The injection molded electroconductive product 6 is placed on an fixing jig 7 and a uniformly applied film is shaped by electrostatic coating with an electrostatic spray gun 8.
