Increase Your Profits by Improving Your Oven
A guide for choosing an efficient, uniform oven system to quickly complete the process.
During the finishing process, curing the coating often has the longest dwell time in the process and is one of the few processes that you can speed up without damaging the quality. Choosing a high-quality oven will enable you to complete the process as quickly as possible.
There are many factors to consider when purchasing an oven. Price shopping is important, but make sure you are comparing apples to apples. Purchase the best quality oven you can afford because a high-quality, uniform oven is more cost effective and can improve quality and increase throughput.
Coaters are not often critical of oven uniformity, but they should be. Completing a batch five minutes quicker could add two or more batches per day, which means more product through the shop and more money saved.
For example, say the business plan is to cure a part in 30 minutes. With a substandard oven, it takes 45 minutes (50 percent longer) to cure, cutting production half. If each rack or cart is worth $1,000 and the line does two racks per hour in an eight-hour shift, the line completes 16 racks, or $16,000, in a perfect operation. The line completes 8.73 racks per shift, or $8,730–$7,270 less than what might have been possible with a better oven.
