Auxiliary equipment for electroplating equipment

If you want to complete the electroplating processing according to process requirements, light power and bath is not enough, there must be some H-wheel also ensure the normal production of electroplating auxiliary equipment. The necessary accessories including heating or cooling equipment, cathode movement or mixing equipment, bath bath and circulating or filtration equipment such as electrode bar, wire electrode, anode and anode basket and electroplating etc..

1 heating or cooling device

Because the electroplating solution needs to work at a certain temperature, it should be equipped with heating equipment for the plating bath. For example, bright nickel plating bath temperature is required to maintain at 50 degrees, the temperature is 50 to 60 degrees Celsius, while the acidic bright copper plating or bright silver plating and requires a temperature of less than 30. In this way, the process requirements need to be met by the heat exchange equipment. In general, the heating method is adopted for heating.

2 cathode movement or stirring device

Some kinds of plating plating or most need cathode in a swing state, tubular strander which can increase the working current of the plating solution to play its due role (usually the brightness and dispersion ability), and can prevent the tip and edge plated hair, burning.

Some kinds of plating can be replaced by mechanical or air agitation. Mechanical agitation is the use of corrosion-resistant materials to do the mixer, usually driven by the motor, but the speed can not be too high. Air agitation is used in addition to the oil filter to the compressed air.

3 filtration and filtration equipment

In order to ensure the quality of plating, the plating solution needs to be filtered regularly. Some kinds of plating are also required to be able to recycle the filter at work. The filter is commonly used equipment in the chemical industry, so there is the industry standard equipment. But also to the enterprise's own standards based. According to the situation and the plating bath size and process need to use.

4 necessary accessories for electroplating bath

The plating tank must be equipped with accessories including the anode and anode electrode, anode basket or hook rod, power connecting wire etc.. Some factories in order to save investment, do not use linked directly to the anode basket, the anode to hang in the plating tank can be, but at least to a set of anode.

Most of the anode basket is made of titanium, and a few kinds of stainless steel can be made of stainless steel or steel.

Electrode rods are used to hang the anode and cathode and to connect the power supply to the conductive rod. Usually made of purple copper or brass rod, slightly longer than the plating tank, according to the current size to determine the diameter, but at least in more than 5cm.

The key of the power cable is to ensure that it can pass the required current. It is best to use copper, but also useful strands of electric cables, it must comply with the requirements of section area.

5 hanger

Hanging is the most important auxiliary instrument in electroplating processing. It is a tool to ensure that the products are well connected with the cathode, and the distribution of the plating layer and the efficiency of the work have a direct impact on the equipment. Has been a professional manufacturer and supplier of hanger provides the industry and general rack according to the needs of the user design and custom-made rack.

6 cleaning equipment before plating

Application of ultrasonic cleaning in electroplating process

The pretreatment process for electroplating products is very important, the traditional process of general acid solution for processing a workpiece, the serious pollution of environment, poor working environment, at the same time, the biggest drawback is the complex structure of the residual acid pickling after the parts are difficult to clean. The workpiece after plating, the time is not long, along the crevice corrosion phenomenon, failure surface plating, seriously affect the appearance and quality of products. Ultrasonic cleaning technology is applied to electroplating before treatment, not only can make the surface of the object and the dirt in the gap quickly peel off, and electroplating electroplating layer firmly won't rust.

The cavitation effect produced by ultrasonic wave in liquid can be cleaned off the oil stain on the surface of the workpiece, and the cleaning agent can be used for cleaning the workpiece surface quickly.

Electroplating process, the workpiece surface cleanliness requirements, and ultrasonic cleaning technology is able to achieve the requirements of the ideal technology. The use of ultrasonic cleaning technology, can replace the solvent cleaning oil; can replace electrolytic degreasing; can replace acid etching to remove carbon and low alloy steel surface rust and oxide skin.
