Embodiment Construction

[0055] The following examples are intended to illustrate the present invention, but not to limit the scope of the present invention. The implementation conditions adopted in the examples can be further adjusted according to the conditions of the manufacturer, and the implementation conditions not specified are usually conventional experimental conditions.

[0056] The sand nickel electroplating process for an automobile door handle according to the present invention comprises the following steps:

[0057] 1) Degreasing

[0058] Degrease and dedust the surface of the plastic base material of the injection-molded car door handle, and then put it into the cleaning tank to rinse with water;

[0059] 2) Coarsening

[0060] The plastic base material is sent into the roughening liquid tank for roughening treatment, and then put into the cleaning tank and washed with clean water. The coarsening liquid is high chromic acid type coarsening liquid, which is 600~800g / LH 2 SO 4 , 50~1...

Abstract

The invention provides a sand nickel electroplating process for an automobile door handle. The sand nickel electroplating process comprises the following steps of (1) degreasing; (2) expansion; (3) alligatoring; (4) reduction; (5) preimpregnation; (6) activation; (7) dispergation; and (8) electroplating. According to the sand nickel electroplating process, a treatment process of a plastic substrate before the electroplating is modified, and the whole process is environmentally friendly and nonhazardous. Special sand nickel electroplating liquid is adopted, and chemical plating is not needed, so that the operation is easier; the process stability is improved; the waste water treatment is simple; the production time is greatly shortened; no rack needs to be replaced in the production process, so that the production rate is greatly increased.

Description

technical field [0001] The invention relates to a sand nickel electroplating process for an automobile door handle. Background technique [0002] Electroplating is the process of plating a thin layer of other metals or alloys on the surface of the base material by the principle of electrolysis. It is a process of using electrolysis to attach a layer of metal film to the surface of metal or other material parts to prevent metal Oxidation (such as rust), improve wear resistance, electrical conductivity, reflectivity, corrosion resistance (copper sulfate, etc.) and improve appearance. [0003] Among them, in addition to iron-based cast iron, steel and stainless steel, the electroplating substrate materials also include non-ferrous metals, or ABS plastics, polypropylene, polysulfone and phenolic plastics, and electroplating on the surface of plastic substrates is called plastic electroplating. . Plastic electroplating products have the advantages of light weight, easy processi...
