Barrel vs Rack Plating

Choosing the proper electroplating procedure is critical for attaining the best results and reducing the risk of harm to the final product. Barrels and rack plating are two of the most regularly used procedures for plating several workpieces and hence, barrel vs rack plating is something everyone wants information about. Each has its own set of benefits and drawbacks that the plater and client must consider when deciding on the best process for their job.

Barrel plating

Barrel plating from the topic  barrel vs rack plating, as the name indicates, includes putting the pieces within a barrel, which is commonly made of polypropylene. The electrical current is conducted via the barrel’s middle bars. While submerged in the electrolytic plating solution, the barrel spins slowly. The components tumble or “cascade” as a result, resulting in an even, consistent coating application. Enhancing corrosion protection, boosting aesthetic appeal, and generating an engineering finish that preserves the components against wear and tear are all common barrel plating uses.

Barrel plating is a cost-effective way to coat a large number of tiny, durable items like stampings and fasteners. It’s also great for plating pieces of all sizes and shapes. Barrel plating involves less capital investment and is less labor-intensive than rack plating, resulting in cheaper process costs for the client. On the negative side, most barrel plating procedures need a low electrical current, which might lengthen the time the components are exposed to the plating solution. Let’s read in detail about the first half of barrel vs rack plating. 


1. You will only utilise one vessel

You can handle any plating demand for your project with the proper barrel size. All you need is one vessel for parts washing, rinsing, pickling, or even sealing.

2. It can deal with a wide range of situations

Any pieces you have will be electroplated in the barrel if you choose the barrel approach. When you have a variety of components to electroplate, you won’t need a lot of different equipment since your barrel can fit any item that fits into it.

3. Ensure that the finish is consistent

Using the former method of the topic  barrel vs rack plating ensures a consistent engineering finish across all electroplated items.

The rotation of a plating process causes metal components to tumble. This cascade allows for bipolar contact between pieces, resulting in a consistent finish. This electroplating procedure is often used to get this outcome after plating metal items.

4. You’ll save money

If you apply barrel plating for your project, you’ll get a low-cost double advantage. It is advantageous to both you and your clients. This strategy will assist you in lowering your operating expenses, as well as providing low-cost service to your consumers.

Additional fittings, component carriers, or agitation equipment may not be required in certain circumstances, further lowering costs.

Rack plating

Now let’s look at the latter part of  barrel vs rack plating. Rack plating varies from barrel plating in that the pieces are screwed, wired, or spring-loaded to metal racks. As a result, when the metal rack is immersed in the plating solution, the components stay immobile. As a result, metal platers favour rack plating for fragile items that may not be able to endure barrel plating tumbling or cascading movement. Large or sophisticated components may also benefit from rack plating.

The rack technique can plate curves and complicated forms more effectively, in addition to providing improved protection against component damage. Rack plating is the chosen finish in areas such as military and defence, automotive, medical, and electronics where a high-quality finish is critical. Rack plating has the disadvantages of being more expensive and requiring more manpower. For unique uses, it may be essential to design and produce a bespoke rack. Let’s learn more about the next half of the topic barrel vs rack plating.


1. It can accommodate plates of any size or shape

This process may be used to plate any size of metal object that has to be electroplated. You may hang them on the rack and continue with the procedure since you are not putting them in a barrel.

Some items with complicated shapes that need contour plating may nevertheless be finished uniformly using the rack plating approach. All you have to do is adapt the rack to meet the project’s requirements and hire qualified engineers.

2. It is quite good at handling delicate components

The rack is ideal for fragile items that are easily damaged. When electroplating metal components with delicate tips, don’t waste time trying alternative ways; instead, go right to your racking equipment and safeguard these parts from harm.

3. Reliable, scratch-free outcomes

All you have to do to prepare the metal components for electroplating is hang them and secure them with hooks or binds. Each object is completely self-contained, with little or no touch with other components. You will see that they are smooth and free of scratches after going through the plating procedure. In rare situations, you may see minor scratches that do not affect the part’s functionality.

4. The ending will be consistent

One significant advantage is that all pieces, even those with complicated geometry, may be finished uniformly. It yields a positive overall outcome.

Metal finishing methods such as zinc, tin, copper, and nickel, as well as precious metals such as gold and silver, are suitable with both barrel and rack plating. There you have it! Now you are aware of all the details you need of the topic barrel vs rack plating.
