A manufacturing process of electroplating parts with wire drawing texture

Abstract

A manufacturing process for electroplating parts with wire drawing lines, the specific steps are: mold cavity wire drawing treatment; mold injection molding plastic products; cleaning oil stains on the surface of plastic products; The conductive layer is plated by PVD, and the conductive layer is formed by sputtering metal plating; finally, the plastic substrate electroplating product with brushed texture on the surface is completed by spraying paint. Since the present invention directly draws on the forming mold to form the drawing pattern on the surface of the product, it avoids drawing the products one by one, reduces the workload, transportation, equipment and labor costs, and realizes the requirement of energy saving; the surface treatment of the product adopts more environmentally friendly Advanced PVD pre-treatment further reduces pollution; at the same time, the water electroplating pre-treatment is changed to semi-dry pre-treatment, which saves the drawing process and greatly shortens the delivery time of the product; the overall cost is reduced by 40-50%.

Description

technical field [0001] The invention relates to a manufacturing method of an electroplating part of a plastic base material, in particular to a manufacturing process of an electroplating part with wire drawing lines. Background technique [0002] At present, the specific production process of electroplated parts with wire drawing lines on plastic substrates is: mold injection molding---chemical degreasing---coarsening---reduction---sensitization---chemical nickel plating- --Pyrophosphoric acid copper plating --- acid copper plating --- semi-gloss nickel plating --- brushed surface --- spray paint, so as to realize the production of brushed surface products. [0003] This process method has the following disadvantages: [0004] 1. In this process, the pretreatment of water electroplating is mainly used. Among them, the chemical degreasing is to use phosphorus-containing chemical agents to remove oil, the roughening process is to use high chromic acid to roughen, and the sens...

Problems solved by technology

[0004] 1. In this process, the pretreatment of water electroplating is mainly used. Among them, the chemical degreasing is to use phosphorus-containing chemical agents to remove oil, the roughening process is to use high chromic acid to roughen, and the sensitization is to use noble metal sensitization and electroless plating. Nickel adopts highly polluting processes such as phosphorus-containing chemical nickel, which will produce a large amount of waste water, waste gas, and waste residue, and the treatment of the three wastes is difficult and costly, and has a great impact on the environment

[0005] 2. The current process is nickel-plating and then drawing, that is, nickel-on-drawing process, which will consume a certain amount of nickel, and the price of nickel metal is high. Such a process will inevitably cause waste of raw materials and increase processing costs;

[0006] 3. From injection molding to painting, the overall production process is many, the cycle is long, and the yield rate is low
