Metal and plastic integrated manufacturing method

Abstract

The invention discloses a metal and plastic integrated manufacturing method. The metal and plastic integrated manufacturing method comprises the following steps of: processing a metal blank; anodizingthe metal blank to generate an oxide pore membrane, then converging or branching the pores of the oxide pore membrane to carry out Y treatment; carrying out modification treatment on a plastic material, to be specific, using a performance additive to increase the thermal deformation temperature of the plastic material and reduce the coefficient of thermal expansion, improving the surface lipophobicity of the plastic material, and reducing the contamination property of the plastic material and an organic pigment; carrying out integrated injection molding on the metal and the plastic, to be specific, putting the metal blank subjected to Y treatment in an injection mold, and injecting the modified plastic material into the injection mold by using an injection molding machine for injection molding; and performing surface treatment after injection molding, to be specific, performing surface treatment on the combination of the metal subjected to injection molding and the plastic. The metaland plastic integrated manufacturing method overcomes the technical problems that a traditional injection molding method causes the indentation and damage of the metal surface, and the inadequate bonding strength between metal and the plastic, a nanometer injection molding mode is expensive, the injection molding conditions are harsh, and the selectivity of the plastic material is low.

Description

technical field [0001] The invention relates to the technical field of metal and plastic injection molding and surface treatment, in particular to an integrated manufacturing method of metal and plastic. Background technique [0002] At present, the integration of metal and plastic generally adopts the combination of injection molding, and there are two injection molding methods for the integration of injection molding and integration: one is traditional injection molding, and the other is nano injection molding. [0003] Traditional injection molding methods can be roughly divided into two categories: the first type is direct injection molding, where metal blanks are first surface treated and placed directly in plastic molds for injection molding to achieve the combination of metal and plastic, commonly known as metal overmolding. The second type is injection molding after bridging. The metal blank is first treated on the surface, and then the metal surface layer is bridged...
