The Process to Create Zinc Plated Pin

Image for post

One of the most common electroplating applications is zinc plating. Its primary function is to protect metal accessories such as fasteners, bolts, nuts, and automotive parts. A zinc plated pin is a solid pin with a flat head that is held in place by a wire formed pin inserted through a hole bored in the other end. There are several pins used in industrial goods.

Zinc can prevent corrosion of the underlying iron and steel. It can also improve the appearance of metal components by adding a variety of hues, brightness, and an attractive gloss to them. In fact, most electroplating businesses will inform you that zinc plating is one of the most commonly utilized methods of galvanizing a metal surface to protect it from corrosion. In this post, we’ll share the process to made zinc plated pin.

Process of Zinc Plating

Zinc electroplating is primarily a technical procedure requiring a high level of expertise. An accessory tank, a rectifier, a reservoir, and a plating station are among the unique machinery and equipment required by the user. The process of zinc plating is described in detail below.

1. Cleaning the Surface

This is done to clean the substrate of any rust, oil, or grime. It's recommended to use an alkaline detergent to keep the zinc plating intact for as long as possible. Blisters and peeling might occur as a result of improper cleaning. The metal is cleaned by immersing it in a bath of 150 to 200° F for 5-10 minutes to remove the grime. After that, an acid treatment is used to assist remove surface rust.

2. Setting up the Electrolyte Solution

In zinc plated pin, the user must immerse the substrate in a special electrolyte solution known as the plating bath. The bath typically contains a variety of chemicals as well as a zinc metal ionic solution, which aids in the efficiency of plating techniques. They can also produce the desired physical and chemical properties in the final product.

3. Zinc Plating

You're ready to zinc plate the components after you've completed the first two stages. At the anode end, a predefined period of DC (direct current) will be applied first. As a result, zinc ions are deposited on the metal's surface (the cathode end). By appropriately positioning the cathode and anode in an aqueous solution and ensuring that the current flows proportionately over the entire surface, uniformity in zinc electroplating can be accomplished.

4. Making Use of Chemical Agents

To acquire the appropriate physical and chemical qualities of the finished product, vendors utilize a number of chemical agents in combination with zinc plated pins. Changes in the chemical agent, the electric charge used, the period of soaking, and temperature and time variables can all affect these.

5. Taking Care of the Finished Product

After every major phase of the zinc plated pin process, it's important to wash the parts with water. After plating, it should be rinsed in a liquid container to remove any potential surface contamination and then dried appropriately. In the event of excessive contamination, rinsing can be repeated several times. Depending on the level of the contamination, the pieces would be washed under flowing water or in a rinsing tank.


A protective zinc covering surrounds the zinc plated pin. Zinc electroplating's main advantages are its simplicity and cost-effectiveness. The procedure produces a nice polish on metals and can be done in a number of colors. Apart from that, zinc is a more environmentally friendly option to cadmium, which is a highly toxic substance that can induce poisoning over time.
