Inventor: MAEKAWA TETSUO
IPC: B29B13/00
Filed: 1981-11-24
Abstract: PURPOSE:To improve adhesion between a filler metal and resin by a method wherein the filler metal used when organic high molecular synthetic resin is injected into a mold is surface-treated in advance by plating a material containing an organic high molecular material. CONSTITUTION:The surface of the filler metal 3 is plated 5 by plating solution where organic high molecular material (hereafter referred to as high molecular grains) 4 is added to create plated layer 5 containing high molecular grains 4 on the surface of the filler metal 3. Then, organic high molecular synthetic resin 1 is injected. Since high molecular grains 4b or 4d is bridged inspite of the existence of oxide coating 2, the adhesion between high molecular grains 4 and injected resin 1 is especially excellent and the adhesion between the filler metal 3 and plating 5 is also strong. Thus, when the surface is treated by the plating solution containing organic high molecular material in the filler metal, adhesion between the organic high molecular resin molded product and the resin can be increased remarkably.
