Curing

Drying times are vital for any business that’s using a drying room in a production process. Ample drying time is essential to achieving a high quality of paint finish on all sprayed products. There are two ways to ensure your drying time actually saves you money, after the spray job: • Maintain a low humidity – high humidity slows evaporation and thus drying times • Maintain even heat distribution – this is achieved through even supply and distribution of airflow A balance between ample drying time and proper heat distribution is vital for a top-class finish in all products, and an efficient output of work.

There are a few options to consider, to make your drying room more effective. 1. Improve the heating mechanism in the drying room 2. Vent the room more efficiently with a stronger extractor fan 3. Consider a dehumidifier as a component in the room

The tunnel oven comes in two categories, direct gas fired, and indirect gas fired. • Direct gas fired – this type cures products using zoned temperature controls that even-out the heat, to regulate the heating chambers. • Indirect gas fired – this type cures products using the ambient heat that comes from burners firing into strategically placed combustion chambers.

This will depend entirely on the dimensions of the material that needs to be coated, and the production capacity. Ultrimax will custom-build a tunnel oven to suit your business, and your specifications.

There are a range of benefits that come from using tunnel ovens in your curing process. These include: • Decreased curing times for high output, and lowered costs • Evenly distributed heat for thicker, more uniform coatings and better-quality curing • Tunnel ovens require less maintenance

Typically, tunnel ovens take 25 to 35 minutes at a set temperature to reach optimum curing status.

Through the use of a uni-flow air distribution system, box ovens are able to distribute heated air on both sides of the unit. This is essentially heat transfer technology, or a highly efficient use of heat. The advantage to this system is two-fold – heat efficiency means energy saving and cost saving.

Apart from not sticking to an established maintenance plan, one of the most common mistakes when using an oven - often leading to failures of several components - is restricting the airflow. This effectively changes the temperature profile of the oven, which leads to overheating and often costly break downs. Care must always be taken to check ventilation, inspect the oven chamber, and ensure the duct work is functioning.

A box oven usually heats up to about 180 to 200 degrees Celsius.
