System Engineers offers the full range of Powder / Liquid curing oven – whether electrical, gas or diesel fired. Whether batch type or conveyorised tunnel type. Designed and built specially for Powder & Liquid curing purposes assuring 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-
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-
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 colour, 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.
The oven is built using double skin, tongue and groove insulated panels, together with high temperature 350 degrees Celsius fiberglass insulation. Cure oven ductwork is designed to circulate air in a way that will maintain even heat throughout the oven and not create turbulence. Excessive air velocity in the cure oven can cause powder to be blown off of parts. It can also cause parts to swing around and hit other parts or the walls on the oven.
The oven size will depend on the size and mass of the product to be run and the production volume. The oven must be sized to handle the largest part with enough burner capacity to handle the heaviest load of product.
A batch oven cycle time will typically be around 15 to 20 minutes. The oven interior should be big enough to handle 20 minutes worth of production.
Even airflow and temperature balance in a convection oven is important. If there are areas that are not even in temperature the coating may not be uniformly cured and colour and gloss may vary.
