Plastic part electroplating method and plastic part electroplating pre-impregnation device

Abstract

The invention provides a plastic part electroplating method and a plastic part electroplating pre-impregnation device. The plastic part electroplating method includes a pre-impregnation method, the pre-impregnation method includes a storing step and an electrolytic step, the storing step includes the steps that a hanger and a plastic par are soaked in the pre-impregnation liquid, and the hanger isconnected to the cathode of the power supply; and the pre-impregnation method comprises the steps of powering on is conducted, electroplating is conducted on the pre-impregnation liquid, a pre-impregnation device comprises an electroplating tank, electroplating plates and a conductive supporting assembly, the electroplating tank is used for loading the pre-impregnation fluid, a conductive part isarranged on the electroplating tank, the conductive part is used for charging the pre-impregnation liquid, the conductive part is connected to the cathode of the power supply, the electroplating plates extend into the pre-impregnation liquid, the conductive supporting assembly is used for supporting the electroplating plates so that the electroplating plates are firmly soaked in the pre-impregnation liquid, and the conductive supporting assembly is connected with the anode of the power supply. In the pre-impregnation liquid electroplating process, the anions in the pre-impregnation liquid istransferred to the hanger and the plastic part and gives the electron so that the hanger and the plastic part form a negative electrical environment, palladium precipitating is achieved better accordingly, and the phenomenon of hanger hook bursting and powder stripping is reduced.

Description

technical field [0001] The invention relates to the field of electroplating, in particular to an electroplating method for plastic parts and an electroplating prepreg device for plastic parts. Background technique [0002] In the electroplating production process of plastic products, since plastic is an insulator, a layer of conductive parts (metal film) must be formed on the surface of plastic products before electroplating. The metal film is used as the underlying metal, and plastic products can be electroplated to form The process of metal thin film is palladium activation. Before the palladium activation of plastic parts, in order to protect the palladium water in the electroplating tank, the chromium solution remaining on the hangers and the products on the hangers in the previous process will not contaminate the palladium water, and the hangers and hangers in the pretreatment process When the product on the rack is diluted with water, it is necessary to pre-soak the r...

AI Technical Summary

Problems solved by technology

In the process of pre-soaking, the residual chromium solution of the hanger and the product on the hanger will be reduced, and the moisture will be neutralized. During the palladium process, the palladium ions are not better attached to the hanger and the product, and the hanger and the product on the hanger are still very prone to explosive hook powder removal (chemical nickel is not fully consolidated on the hook head of the hanger) , causing impurity pollution to the subsequent electroplating process, and sand spots are easily formed on the surface of the product, resulting in defective products
