  • Six Precautions for Silver Plating on Aluminum

    June. 01, 2023

    Silver plating on aluminum and its alloys is much more difficult than silver plating on general copper parts, and the process is also relatively complex. The main reason is that the properties of aluminum and its alloys are different from other metals. Aluminum is a zwitterionic metal that reacts with both acids and alkalis. Improper pre-treatment can cause surface corrosion. Moreover, aluminum and its alloys are prone to producing oxide films in both air and solution. If this oxide film is not removed thoroughly, it will affect the adhesion of the coating.

  • What are the requirements for plastic electroplating on plastic parts

    April. 19, 2023

    The quality of plastic electroplating is mainly determined by the adhesion between the coating and the plastic substrate, as well as the distribution performance of the coating. To obtain good plastic electroplating parts, in addition to using excellent electroplating processes, it also largely depends on the quality of the plastic products themselves, especially for decorative electroplating parts that perform more prominently in this regard. If we do not consider the characteristics of the electroplating process and blindly design and process the molds for electroplating plastic products, as well as arbitrarily inject them into the mold, it will lead to inherent deficiencies in the plastic products. During the electroplating process, there will be numerous problems, resulting in a decrease in production efficiency, a decrease in qualification rate, and serious waste of materials and labor hours. This is not cost-effective, but it is often overlooked.

  • Pretreatment process - Introduction of ultrasonic cleaning principle

    August. 12, 2022

    Ultrasonic cleaning principle: the ultrasonic cleaning machine is used to amplify the electric power of the oscillating signal with a frequency higher than 20kHz through the ultrasonic generator, and then convert it into high-frequency mechanical vibration energy through the inverse piezoelectric effect of the ultrasonic transducer (vibrating head). Through the acoustic radiation in the cleaning medium, the cleaning liquid molecules vibrate and generate numerous tiny bubbles. The bubbles form and grow in the negative pressure area along the ultrasonic propagation direction, and close rapidly in the positive pressure area to generate the instantaneous high pressure of thousands of atmospheres and burst, forming numerous micro high pressure shock waves that act on the surface of the cleaned workpiece. This is the "cavitation effect" in ultrasonic cleaning.

  • Fault and treatment of bright nickel sulfate plating: poor brightness of nickel plating

    August. 09, 2022

    The poor brightness of the coating mostly occurs in the low current density area, and occasionally occurs in the medium current density area or the high current density area. The poor brightness of the coating in the low current density area may be caused by the high temperature of the plating solution, the low current density, the low concentration of the main salt, the excessive secondary brightener or the presence of copper and zinc impurities in the plating solution; The poor brightness of the coating in the middle current density area may be caused by too little secondary brightener, too much organic impurities or a certain amount of iron impurities; The poor brightness of the coating in the high current density area may be caused by too high pH value of the plating solution, too little primary brightener or a small amount of chromate, phosphate and lead impurities in the plating solution. In addition, poor pretreatment, alkali film or organic adsorption film on the surface of the plated part, or poor bottom plating may also lead to poor brightness of the nickel layer.

  • Pretreatment before electroplating

    June. 20, 2022

    In the electroplating industry, there is often a saying that "there are defective products in electroplating production, half of which are not clean after degreasing". Numerous facts have proved that this statement is somewhat reasonable. Long term production practice has proved that if there are organic substances such as oil stains on the metal surface, sometimes the coating can be deposited, but the flatness, adhesion and corrosion resistance of the electrodeposited coating are always affected by the "interlayer" of oil stains, and even the deposition is discontinuous, loose, and even the coating is stripped off, so that the actual use value is lost. Therefore, degrease before plating becomes an important process operation.

  • Correct method of removing impurities by electrolysis

    May. 26, 2022

    Electrolytic treatment is a common method to remove impurities in electroplating industry. Electrolytic treatment is also an electroplating process, but it is not for the purpose of obtaining a good electroplating layer, but for the purpose of removing impurities (or adjusting the component content of the plating solution). The difference is that instead of hanging parts on the cathode, it is an electrolytic plate (also known as false cathode) made by hanging to remove impurities. Under the condition of power on, the impurities are deposited, clamped or reduced to relatively harmless substances on the cathode electrolytic plate.
