How to choose the suitable powder coating cure oven ?
Choosingthe suitable oven for the applications depends on all sorts ofvariables, including the product size, shape, thickness, materialcomposition, and production throughput, operating cost and type ofenergy to be used must be considered.
Curing Ovens should be designed to ensure efficient use of production labour and minimum maintenance is required.
Temperatureshould be exactingly controlled, if possible within 3 degrees of thespecified curing temperature, temperature indicating heads should besituated as near as possible to the path of the workpiece in the oven.
Convectionovens is most popular method where gas or oil-fired heaters are used toheat air. This is circuilated through an enclosed space where itprovides the requiremd temperature. The powder coated pieces are carriedin to oven, reach the surrounding temperature and keep this temperaturefor the set time.In a direct fired oven, the products of burnercombustion are carried directly in to the heat holding zone, in an indirectly fired oven the burner products pass through a heat exchanger so that only clean air enters the heat holding zone.
Infrared ovens Generally,infrared heat energy is emitted by a hot body and transferred instraight lines untill it makes contact with another body when the heatis absorbed by the latter causing it to rise in temperature.
