On the other hand, if the substrate and the powder have not reached sufficient temperature for the proper amount of time, as specified by the powder manufacturer, the powder coating material will not cross-link at all. To proactively manage your cure window two different types of checks are performed. Second, and most importantly thermal profiling checks are made on the parts as they are being cured. This data is commonly used as proof of conformance to end use customer that the finish was cured to the powder manufacturer's time at temperature specification. If costs go up, profits go down.
Profits are simply money received in excess of costs.
Rejects eliminate more than Profits from the equation. The cost associated with each of the above mentioned examples can be tracked over time. The exact cost of rejects over time is never a simple formula. Many factors must be considered to realize the exact cost of failure, and in each case it will be different. In some cases the result of failure is not always possible to calculate with a simple mathematical equation.
