4 Most Commonly Used Sizes of Powder Coating Ovens and When to Use Them


There are four most commonly used sizes of powder coating ovens- small, medium, and large. Depending on the size of the item being coated and the type of powder being used, one of these three sizes will be the best fit. Small powder coating ovens are typically used for smaller items, like car parts. Medium powder coating ovens can accommodate larger items, like industrial machinery. Large and extra large powder coating ovens are reserved for very large items, like steel beams.

When to use the small powder coating oven?

Smaller ovens are best for coating small items that can fit through the opening of the oven. They are also ideal for low production shops or shops that don’t use their ovens on a daily basis. Smaller ovens are easier to manage than larger ovens and are more efficient because they use less electricity or gas. If you’re just starting out and don’t have a large production volume, a smaller oven is a great option. Additionally, you might want to consider a smaller oven if you don’t have a lot of space in your shop. As you can see, there are several situations when a small oven makes sense.

When to use medium powder coating oven?

This is the best choice for small businesses looking to move up from a small oven but who don’t need the high volume capabilities of a large oven. For most small businesses, a medium-sized oven or booth such as an 8x12x25 Powder Coating Booth is the best option as it offers the best of both worlds. It’s large enough to handle most production runs but small enough to fit in most warehouses. It’s also the most cost-efficient option as it allows most businesses to forgo the need for special gas lines, electrical connections, and other expensive requirements needed for large ovens. Most manufacturers like Reliant Finishing Systems offer customization options for these medium-sized ovens, allowing you to select the size and other features that best meet your needs.

When to use a large powder coating oven?

When you need to apply a coating to large pieces of metal. For example, if you need to coat the side of a cargo ship, you will need a large oven. Large ovens can hold up to 25 tons of material. In comparison, standard industrial ovens hold about 2 tons. Large ovens are also necessary for large-scale industrial processes. Large industrial ovens are used for larger curing processes. You also need a large oven if you want to apply coating to things that are too big to fit in a standard industrial oven.

When to use the extra large ovens?

An extra large powder coating oven is ideal for high-volume production and it is especially good for large or awkwardly shaped items. The large size of the chamber lets you fit in larger pieces, and the insulation properties keep the heat in and help to maintain a steady temperature. An extra-large powder coating oven is a good choice for small businesses or companies that do a lot of large-scale work, as they can accommodate large pieces.


There are four commonly used sizes of powder coating ovens: small, medium, large, and extra-large. Each size has its own benefits and drawbacks that should be considered when choosing the right oven for your needs. Ultimately, the decision of which size to use depends on the specific project requirements.
