Both factors have an enormous impact on producing consistent, quality parts.
When shopping for an oven, countless items need to be considered when trying to select the best vendor for your project. Obviously, the initial investment is a major factor, but purchasing the cheapest oven may actually cost your company more money in the long run. Besides price, factors to be considered include the vendor’s ability to meet your requirements and specifications to ensure the equipment will work for the application. It is also important to pay close attention to airflow design and temperature uniformity, both of which can have an enormous impact on obtaining quality results on a consistent basis. Although proper airflow design and temperature uniformity are closely related, they should be evaluated separately to avoid issues once the equipment arrives at the job site and you begin running your product.
Remember, you can buy an oven with excellent empty oven chamber temperature uniformity and still not obtain acceptable results. If the airflow is not designed for the way you load your parts inside the oven, you will not achieve the projected uniformity. Only by buying an oven with acceptable temperature uniformity and the proper airflow design will you be on your way to maximizing your production rates and improving your product quality.
Understanding what is necessary to achieve optimal temperature uniformity in your oven and how to match the airflow to the way the products are loaded into the oven will help you get the results you desire.
