Recently, the thinning of the plastic product is advanced. However there are any abuses of the formability with it. It is reduced by conducting surface modification to the metallic material, which constitutes metallic cavity, barrel in molding machine, screw. Then, it is possible to improve the resin adhesive strength, and it aims at next fact. That is to say, it is the filling in the low voltage of the melting resin. It is the reduction in the mold release in the mold release force. It is the generation of the contamination of the melting resin by the retention adhesion prevention of the melting resin. It is the research of the metal surface reforming for the purpose of these.
