Curing Oven

Product Details:

Precision System offers the full range of Powder / Liquid curing oven – electrical, gas or diesel fired, batch type or conveyarised tunnel type. Designed and built specially for Powder & Liquid curing purposes our curing ovens assure you of low power consumption with uniform temperature throughout the working space in the oven. When a thermostat powder is exposed to elevated temperature, it will begin to melt. As the material begins to melt, it will flow out and then chemically react to form a higher molecular weight polymer in a network-like structure. This cure process, called cross linking, requires a certain degree of temperature for a certain length of time in order to reach full cure and establish the full film properties that the material was designed for.

A convection oven uses a heat source, most commonly a gas burner, and a fan to heat the interior of an insulated enclosure. Different powder materials require different cure temperatures, commonly in a range between 150-250 degrees Celsius. The part is heated by the hot air in the oven and it in turn conducts heat into the coating. The coating must be held at a certain temperature for a predetermined length of time to reach full cure. So the cure cycle is done for so many minutes at so many degrees of temperature. The time it takes to bring the metal up to the required temperature must be added to the cure time requirement to determine the full cycle time in the oven.

Convection cure time may be as short as 10 minutes or as long as 30 minutes, depending on the mass of the substrate and the cure requirements of the powder. Convection curing is dependable and flexible. The oven can be adjusted along a full range of temperature requirements and the line speed can be adjusted for the time requirement. The part can be exposed for a longer period of time than what is called for, usually with no change in color, gloss or performance in coating. Energy consumption is related to the load of product, the amount of insulation and volume of exhaust. Typically, a gas fired oven is very efficient and cost benefit.
