A brief introduction of the ultrasonic cleaning process for several common Copper Stamping Parts surface conditions before electroplating
1-Cleaning of polishing paste on the surface of polished Stamping Parts Copper Spring: Generally, the polishing paste is often blended with paraffin wax. The molecular weight of paraffin wax is large, the melting point is high, and it is solid at room temperature. It is difficult to clean. The traditional method is to clean with organic solvents. Or boiling and washing in high temperature alkaline water has many disadvantages. When ultrasonic cleaning is used, water-based cleaning agent can be used. The surface of the Copper Spring Electrical Parts can be thoroughly cleaned in a few minutes under medium temperature conditions. The common process flow is: ①soaking→②ultrasonic cleaning→③clean water (clean water) rinsing.
2-Cold-rolled Stamped Copper Terminal with oil and a small amount of rust on the surface: Generally, the surface of cold-rolled Copper Stamping Processing has oil, dirt or a small amount of rust. It is easier to clean it, but after cleaning by general methods, a very thin layer of float remains on the surface of the Copper Stamping. Ash affects the quality of subsequent processing, and sometimes it is necessary to use strong acid soaking to remove this layer of floating ash. The use of ultrasonic cleaning and the addition of appropriate cleaning fluid can quickly and easily achieve a thorough cleaning of the surface of the Stamping Copper Sheet, and make the surface of the Custom Copper Stamping more active, and sometimes even eliminate the acid leaching activation process before electroplating.
3-Copper Sheet Stamping with oxide scale and yellow rust on the surface: The traditional method is to use hydrochloric acid or sulfuric acid to soak and clean. If the ultrasonic comprehensive treatment technology is adopted, the oil and rust on the surface of the Electrical Copper Stamping Parts can be quickly removed within a few minutes, and the hydrogen embrittlement problem caused by strong acid cleaning can be avoided.
Metal Custom Copper Stamping process characteristics:
(1) Copper Stamping is a processing method with high production efficiency and low material consumption. The stamping process is suitable for the production of larger batches of parts, which is easy to realize mechanization and automation, and has high production efficiency. At the same time,Copper Sheet Stamping production can not only strive to achieve less waste and no waste production, but also has margins in some cases. The leftover material can also be fully utilized.
(2) The operation process is convenient and does not require the operator to have a higher level of skill.
(3) The Electrical Copper Stamping Parts generally do not need to be mechanically processed, and have high dimensional accuracy.
(4) Metal Stamping Parts Electric Copper have better interchangeability. Stability of stamping processing is better, the same batch of stamping parts. Can be used interchangeably without affecting assembly and product performance.
(5) Since the Copper Stamping Parts are made of plates, its surface quality is better, which provides convenient conditions for subsequent surface treatment processes (such as electroplating and painting).
(6) Copper Strip Stamping can obtain parts with high strength, high rigidity and light weight.
(7) The cost of Red Copper Stamping Parts produced in batches with molds is low.
(8) Precision Copper Stamping Parts can produce parts with complex shapes that are difficult to process with other metal processing methods.
