Abstract

The invention discloses a metal base material and a metal and plastic bound part. The surface of the metal base material is provided with a micron-scale concave-convex surface and honeycomb-shaped fine holes, wherein the average width RSm of the contour of the micron-scale concave-convex surface is 1-400 microns, the average peak valley depth Rz of the contour of the micron-scale concave-convex surface is 1-15 microns, the honeycomb-shaped fine holes are formed in the micron-scale concave-convex surface, the average hole size of the honeycomb-shaped fine holes is 10-500 nanometers, and the micron-scale concave-convex surface is configured to bear a plastic material subjected to injection molding. The metal base material and the metal and plastic bound part have the technical effect that binding action force of the plastic material connected to the metal base material and the metal base material can be improved.

Description

Technical field [0001] The invention belongs to the technical field of material processing, and specifically relates to a metal substrate and a metal and plastic combination. Background technique [0002] In the electronic communication industry, more and more electronic products use metal and plastic composite forms to form product structures. This structural design can achieve rich functional effects. For example, in the case where the appearance of the product is required to exhibit metallic characteristics and the internal structure needs to reduce weight and save material costs, a metal and plastic composite design can be adopted. [0003] The traditional way of compounding metal and plastic includes adhesive bonding, snap-fitting or rivet connection. However, the traditional composite method has disadvantages such as low composite reliability and the need to increase the fixed connection mechanism. With the development of technology, a composite method of injecting plastic ...
