Problems solved by technology

[0003] At present, a single electroplating can no longer meet the requirements of customers. The current plastic products need to be electroplated with multiple metals at the same time to meet the needs of the product; but due to the respective characteristics of various metals, it is often difficult to electroplate several metals on the workpiece at the same time.

Abstract

The invention discloses an electroplating process for continuously electroplating molybdenum, gold and tin. The process comprises the following steps of 1, feeding a workpiece; 2, removing oil stain and dirt on the surface of the workpiece; 3, neutralizing alkaline substances on the surface of the workpiece and activating the surface of the workpiece; 4, electroplating molybdenum; 5, electroplating gold; 6, electroplating tin; 7, neutralizing and washing; 8, airing and drying; and 9, collecting. Continuous electroplating of molybdenum, gold and tin is realized by adopting the reasonable process, and molybdenum, gold and tin are electroplated on the workpiece synchronously, so that the requirements of customers are met.

Description

technical field [0001] The invention relates to an electroplating process, in particular to an electroplating process for continuously electroplating molybdenum, gold and tin. Background technique [0002] Plastic electroplating products have the advantages of light weight, good corrosion resistance, easy molding and metal organic solvent resistance, light resistance, metallic luster, thermal conductivity, electrical conductivity, electromagnetic shielding, and easy welding. They are used in automobiles, motorcycles, Widely used in hardware, electronics, communication and other industries. [0003] At present, single electroplating can no longer meet the requirements of customers. The current plastic products need to be electroplated with multiple metals at the same time to meet the needs of the product; however, due to the respective characteristics of various metals, it is often difficult to electroplate several metals on the workpiece at the same time.
