Plating Tanks for Galvanizing Plants
Plating Tanks for Galvanizing Plants are containers in which preparatory, primary, and finishing operations for galvanization are conducted. They serve as the main equipment in the production line for galvanizing. Galvanic baths can be equipped with additional accessories according to the client's preferences, including a metal frame, heating elements, drains, fittings, flanges, partitions, and covers.
Plating Tanks for Galvanizing Plants
Plating Tanks or Galvanic baths are commonly used in chemical production for both preliminary and primary galvanization operations. In this process, one metal is treated with another through electrolysis. It's a complex chemical procedure, so galvanic baths need to be durable, have low thermal conductivity, and be tightly sealed. They must also resist reactions with substances contained within them.
The principle of operation of galvanic baths involves an electrolytic process conducted within a container where an electrical current of a specific polarity and strength is applied. The structural features of the construction must ensure uniform distribution of electricity over the surface of the contents to facilitate a proper electrolytic process.
Among the requirements for the design, not only sealing and reliability are highlighted but also minimizing voltage losses. The structure should be cost-effective, and losses should be kept to a minimum.
TYPES OF BATHS
There are several variations of galvanic baths serving different purposes and used in various situations:
PROPERTIES OF POLYPROPYLENE BATHS
Galvanic baths made of polypropylene meet all the requirements imposed on electrochemical constructions: they are reliable, leak-proof, and do not react with the contents.
The following properties are characteristic of polypropylene baths:
Like most complex constructions, the production of polypropylene galvanic baths begins with calculations, determining structural features, and creating drawings. After considering the necessary materials, developing the required processes, and calculating, the technical documentation is transferred to the customer for possible amendments.
Once the project is approved, the manufacturer proceeds with the production of the structure. The necessary elements are welded and connected to each other, with special attention paid to the welded joints to ensure strength and tightness.
The finished polypropylene product is tested for compliance with specifications and is delivered to the customer only after passing the required tests.

Plating Tanks for Galvanizing Plants
Types of plating tanks
The standard regulates the possible types and sizes of plating tanks, taking into account their purpose.
Tanks without pockets:
They come in several execution variants.
The standard regulates the possible types and sizes of plating tanks, taking into account their purpose.
Tanks without pockets:
They come in several execution variants.
Execution No. 1. The simplest design of a plating tank, filling and draining of the electrolyte are done through the top edge using feed pumps or manually.
Execution No. 2. The filling and draining of the solution from the plating tank occur through a pipe installed at the bottom of the side wall.
Execution No. 3. The filling and draining of the solution from the plating tank occur through a pipe installed at the bottom of the tank.
Galvanic tanks with a pocket have two types of execution depending on the specific location of the technological pipe.
The pipe of the galvanic tank is located in the lateral part of the pocket. The drain fitting is connected to the side of the pocket wall from any direction depending on the placement.
The pipe is located at the bottom of the pocket.The lower position of the drain ensures maximum removal of the solution.
The tanks are used for galvanic processes, chemical and electrochemical degreasing, etching, hot and cold rinsing of various parts and products. The pockets of the galvanic tank can be located on any side depending on the customer's preferences, with a height within 10-20% of the wall height. The pockets are used for partial drainage of contaminated solution and to prevent electrolyte overflow when loading large parts into the tank.
Multi-chamber tanks:
These are more complex elements used for quality rinsing of parts before and after coating. They come in several types.
Multi-chamber tanks:
These are more complex elements used for quality rinsing of parts before and after coating. They come in several types.
Two-chamber tanks with bottom drain: Due to the cascade arrangement, solution overflow is achieved.
Two-chamber tanks with side drain: Drainage fittings can be connected from both ends.
Three-chamber single-cascade tanks: Three cascades allow for improved processing quality of parts in one tank filling.
Three-chamber double-cascade tanks: The middle compartment of the tank is constantly cleaned from floating contaminants.
Four-chamber tanks with side drain: The side pocket serves to accumulate excess solution during the immersion of a large number of parts.
With bottom drain: The bottom placement of the drain allows for space-saving in the facility, as tanks can be positioned closer to each other.
Depending on the specifics of the electroplating process, parts can be rinsed using various technologies, improving processing quality and reducing time. The drawback of multi-cascade tanks is their large size, which can pose challenges during installation in small-footprint production workshops.
