With the development of manufacturing, Electroplating tank The shapes are becoming increasingly complex, and the requirements and standards are constantly rising. In particular, for small and intricate parts, it is difficult to achieve a high pass rate of finished products using only conventional hanging cathode plating. Compared with traditional electroplating methods, rotary electroplating offers distinct advantages.

The electroplating tank is used to hold plating solutions for processes such as galvanizing, copper plating, nickel plating, and gold plating. The movable cathode electroplating tank consists of a steel tank lined with soft PVC plastic, a conductive device, steam heating tubes, and a cathode-moving mechanism. The tank body can also be made with a steel lining reinforced by rigid polyvinyl chloride; the choice of tank structure depends on the properties and temperature of the plating solution. The tank is driven by a motor, a reducer, an eccentric disc, connecting rods, and support roller wheels.

I. Applications

The electroplating tank is used to hold the plating solution and is employed for processes such as galvanizing, copper plating, nickel plating, and gold plating.

II. Classification

Electroplating tanks can be categorized into alkaline electroplating tanks, acidic electroplating tanks, chrome-plating tanks, chemical degreasing tanks, electrochemical degreasing tanks, pickling tanks, chemical polishing tanks, electrochemical polishing tanks, water-washing tanks, and storage tanks, among others.

Depending on the materials used, there are tanks made of titanium plating (resistant to corrosion by acidic and alkaline solutions), PP, PVC, PVDF, FRP, stainless steel, granite, and polytetrafluoroethylene (which can be used in any acid).

III. Selection Guide

The selection of materials for electroplating tanks typically depends on the corrosivity of the medium used and the operating temperature. Generally, alkali tanks can be made of iron, while acid tanks must use acid-resistant materials. For example, sulfuric acid media can be handled by lead-lined tanks, whereas hydrochloric acid media can be accommodated by enamel-coated tanks. When heating is not required, plastic water tanks are an excellent choice.

Generally, the size of an electroplating tank refers to the volume (in liters) of the electrolyte contained within the tank’s cavity—that is, the length, width, and depth of the electrolyte in the tank’s cavity. Such dimensions are typically determined and selected based on factors such as the required plating capacity or the specifications of existing DC power supply equipment. Selecting an appropriately sized electroplating tank is crucial for developing production schedules, estimating output, and ensuring high-quality plating. When determining the dimensions of an electroplating tank, it is essential to meet the following three basic conditions:

1. Meet the electroplating requirements for the parts to be processed. If the parts can be fully immersed, all surfaces must be electroplated.

2. Prevent the electrolyte from overheating;

3. It can maintain a certain stability in the electrolyte composition throughout the electroplating production cycle.

Of course, at the same time, we must also take into account the overall coordination of the production line to meet the requirements for a rational layout of the electroplating workshop.

4. Precautions for Using Electroplating Tanks:

1. When preparing the plating solution, first add sulfuric acid, then cool it to room temperature before adding copper oxide. After cooling again, add the plating solution.

2. During use, the plating solution level should be higher than the outlet of the reflux liquid.

3. After using the electroplating tank, promptly clean up any spilled liquids around it to prevent corrosion of nearby instruments.

4. Do not use Electroplating tank At this time, cover the electroplating tank with a lid to prevent the plating solution from evaporating.
