If your work requires the need of powder coating, then you must first make sure that in this process, you must require an oven specifically known as a powder coating oven. This oven plays a significant role in the powder coating process, and it is one of the expensive pieces of equipment you install for the powder coating process. In the market, you can find a number of ovens with different specifications, but it is very necessary to go through the details of each of the ovens because this can help you to get the pros and cons of each powder coating oven. By getting these details about different types of ovens, you can easily find the perfect oven to meet your needs as well as your budget.
Types of powder coating ovens
You can find several powder coating ovens that depend upon their curing method. Among them, the two most common methods for curing based on which multiple ovens are present are infrared curing and convection curing.
1. Convection powder coating ovens
The convection oven uses the methodology of convection heat transfer to raise the temperature of the entire oven. In these ovens, the air is heated, through which powder melts and flows. This melted powder ultimately makes a film on the substrate that has been placed in the oven. The main dominant characteristic of this oven is that the heated air is efficiently circulated in the oven chamber without affecting the powder-coated substrate. This oven is fitted with a fan responsible for the proper circulation of heated air within the oven. Within the heading of convection ovens, you have two options.
-
Gas-powered ovens
Gas-powered convection powder coating ovens are relatively cheaper than electric ones, but you must store sufficient gas to operate that oven which can be problematic. Otherwise, it is a good option.
-
Electric powered ovens
Electric-powered convection powder coating ovens are more common nowadays. These ovens are available in different qualities, due to which even those who have a low budget can afford it. The main drawback of the electric-powered convection powder coating ovens is their small variation in the heat control compared to the gas ones.
2. Infrared powder coating ovens
The infrared powder coating ovens work on the methodology of infrared heat transfer in which the substrate is heated by the direct transfer of the radiation on its surface. The infrared powder coating oven performs the whole curing process in a much lesser period than the convection process due to its unique way of heat transfer. The infrared ovens also have some drawbacks and limitations which limit their usage. These ovens are much more expensive than others, and you just have to care about the reachability of the infrared waves to the substrate; otherwise, no curing will be performed. The infrared powder coating ovens are mostly used in the factories and industries where high production is needed, and where the substrates are usually of uniform shapes to enhance the infrared waves exposure.
Final words
As there are numerous ovens available in the market, but before buying that, you must check out, it’s all specification, safety hazards, and its design. You can also contact a professional dealer who can properly guide you about the pros and cons of different ovens according to your need.
