Description

The thermosetting powder’s chemical reaction begins in ovens. Ovens produce and maintain heat — the sole cause of the chemical reaction needed in powder coating. Powder-coated parts must be exposed to heat to achieve the user-specified properties. The proper amount of heat at a given time ensures that the desired decorative, chemical, and mechanical properties are realized. Since many powder-coating operations are also high-speed production operations, heating functions must be carried out in the most efficient and cost-effective manner. A particular application’s requirements must be thoroughly studied and matched with the oven’s capabilities. Therefore, thoroughly investigating each aspect of the heating components of a powder finishing line is critical to achieving an efficient, effective, and satisfactory operation. Ovens are an important component in the powder-paint system. They must work properly to ensure worker safety and consistent results in the curing process. The oven profile is a tool to help evaluate the cure process. An oven-profiling system monitors the part’s temperature as it passes through the thermal process. Thermocouple sensors are attached to the product.
