Zinc electroplating equipment

Types of zinc electroplating equipment

Zinc electroplating equipment refers to the devices used in the electroplating process, which coats objects with a thin layer of zinc through electrolysis. The electroplating process involves creating a stable electrolyte solution containing zinc salts, to which the anode and cathode are respectively attached. The object to be plated is the cathode in the zinc electroplating tank equipment and is bonded to the negatively charged terminal. As a product of the electrochemical reaction, zinc ions move towards the object, creating a protective and decorative zinc layer.

The core component of zinc electroplating equipment is the zinc electroplating tank, which can be made from several materials, including PP, PVC, CPVC, PVDF, rubber, and steel. Additional accessories such as busbars, anode baskets, and supporting racks may be made of copper, stainless steel, or a combination of both. Manmade materials are often coated with polymers or epoxy used to insulate the tank interior, while steel tanks may be coated in rubber to increase their longevity. Electroplating tanks come in a variety of sizes and shapes. Utilizing the right plating tank can affect the outcome of the plating process, such as the uniformity of the coating on the substrate.

Anodized baskets are used to hold the anodes in place and facilitate the movement of the electrolyte within the tank. Like the tank, anode baskets can be made from a variety of materials and may even have a polymeric coating on the exterior. To ensure the even distribution of the current throughout the electroplating process, busbars connect the power supply with the anodes and cathodes. For instance, copper is a good electrical conduit, making it an ideal choice of material for busbars, which are frequently connected to the electroplating equipment with bolts or lugs.

Power supplies regulate the current density in zinc electroplating setups, which in turn helps control the growth rate and deposit characteristics of zinc on the substrate being plated. Current density, voltage, frequency, and ripple are all factors of the electroplating setup that the power supply controls. In most modern setups, switching power supplies are used since they are more efficient, smaller, and produce less heat than linear power supplies.

Supplementary equipment for zinc electroplating includes rinsing and pickling equipment. Rinsing equipment removes contaminants from the surface of the object being plated and is brushed, gunned, or fogged onto the surface before plating to aid in adhesion enhancement and contamination removal. Dipping tanks for rinsing are generally made out of PVC. Pickling equipment, on the other hand, is used to smoothen roughened or oxidized areas of the substrate made out of steel. Unlike the strict environmental regulations surrounding the use of chemicals for rinsing, there are no such rules for pickling solutions, which may contain an acidic electroplating solution inside a stainless steel tank.

Other pieces of equipment that may be helpful for zinc electroplating include deionized water systems that are used to eliminate ionic and inorganic contaminations in areas where hard water is utilized, as well as fume extraction systems that are utilized to manage hazardous fumes that are produced during the electroplating process air handlers.

By familiarizing themselves with the various types of zinc electroplating equipment, suppliers should be able to confidently select the right equipment for their needs as well as better understand how to care for it and use it properly. Proper care and maintenance of good quality zinc electroplating equipment is essential if they are to prolong its lifespan and achieve optimum results.

Specifications and maintenance of zinc electroplating equipment

Specifications of electroplating equipment will vary depending on the type and the particular application for which it is intended.

• Size: Electroplating equipment can be small-scale such as a bench tank, or larger industrial size with many multiple tanks. Many pieces of electroplating equipment, such as tanks, rectifiers, and power supplies, will be customized to specific requirements.
• Materials: Electroplating tanks will typically be produced using corrosion-resistant materials such as PVC, CPVC, or PVDF. This avoids tank deformation, leakage, and other issues. Electroplating equipment components, such as rectifiers and anodes, are typically made of copper and brass. Copper and brass are malleable metals that easily bend to form rivets or bolts. Brass is a durable metal made up of mostly copper, which is a soft metal that, when hard enough, can be used in plumbing. Electroplating equipment also includes water-cooled anodes formed from copper or brass. The electrodes used in the electroplating process are also made of various metals (typically nickel or chromium) that can hold a charge and transfer metal ions.
• Electroplating capabilities: Equipment may be available to buyers that can handle specific weights, sizes, and shapes of objects (generally by measuring length, width, and height), as well as devices capable of electroplating certain metals (e.g., zinc, gold, silver, copper, etc.). The required voltage and current are also part of the specifications of electroplating equipment.
• Automation system: A control system can manage and monitor critical electroplating parameters such as temperature, pH value, current density, plating speed, and more. Some control systems have functions such as automatic feeding, output monitoring, alarm, and data storage. An automatic feeding system ensures that the objects to be electroplated are immersed in the electroplating solution. This is a crucial and controlled step, as improper application and immersion can result in incorrect or damaging outcomes.

It is crucial to adhere to the manufacturer's maintenance instructions when using zinc electroplating equipment, as factors such as the environment, frequency of use, and the miscibility of the water used will impact any required maintenance tasks.

• A regular electroplating tank cleaning schedule should be created and used, as well as ensuring that no plating solution or other liquids are spilled onto electrical components.
• The plating solution in the tank should be maintained at a consistent level to prevent damage and further potential issues such as inconsistent plating.
• The anodes should be regularly inspected, as consistent and uniform electroplated zinc equipment relies on proper anode function.
• Electrical equipment should be inspected for corrosion and other potential issues.
