Process for making plastic surface by electroplating

Abstract

The present invention relates to an electroplating process on plastic surface. It is applicable for forming a multiple metal layer on surface of plastic element. Said process includes the following steps: firstly, forming an electroconductive medium on surface of plastic element, then adopting electrolysis-free electroplating mode to form at least one chemical metal layer (for example chemical copper layer and chemical nickel layer) on surface of plastic element, then regulating material characteristics of surface of plastic element and adopting electrolytic electroplating mode to form at least one electroplated metal layer (for example electroplated copper layer, electroplated nickel layer and electroplated chrome layer). Said electroplated metal layer has high structure strength and high conductivity.

Description

technical field [0001] The present invention relates to a plastic surface electroplating manufacturing process, and in particular to a plastic surface electroplating manufacturing process integrating single-sided electroplating and double-sided electroplating manufacturing processes. Background technique [0002] As far as the current surface treatment technology of plastic components is concerned, in order to form a metal layer on the surface of the plastic component to beautify the surface appearance of the plastic component, or to allow the surface of the plastic component to have a metal shielding effect, the known technology generally uses spray It can be achieved by painting or electroplating. Electroplating can be roughly divided into two types: "electrolytic plating" and "electroless plating (also known as chemical plating)". First of all, the principle of electrolytic plating is that the metal ions in the metal salt solution receive external electrons to become met...

Problems solved by technology

However, since the double-sided electroplating process must go through a roughening process, it mainly involves immersing the plastic component in an acid solution to roughen the surface of the plastic component, which will destroy the original characteristics of the material of the plastic component (such as toughness)

In addition, due to the above-mentioned roughening process, double-sided electroplating also has a further disadvantage, that is, the effect of selectively electroplating the partial surface of plastic components cannot be achieved.
