Gas Catalytic Infrared Ovens

If your company is involved in any type of finishing, such as Powder Coating or Liquid Finishing products and parts, then you will either be subcontracting the work out, or will have your own in house finishing system. Alternatively, you may be thinking of moving from a liquid finish to a powder finish. Whatever your situation, the drive for cutting the cost of manufacturing is ever present, so this article will outline the various finishing oven technologies available, to help you choose either a new system, or upgrade your existing facility.

Gas Catalytic IR Dry-off & Booster Ovens

Production bottlenecks often occur as a result of tougher production demands, where the existing drying system can no longer keep pace. This can often be solved by an infrared booster section, which is positioned in front of the existing drying system.

Infrared booster oven

An IR booster section rapidly brings the product up to temperature allowing line speeds to be increased accordingly. For some products this can equate to savings of up to 50% of the time required to dry or cure the coating.

The use of IR booster ovens is flexible. They can be placed before, or between existing ovens.

Your advantages using infrared boosters:

  • Saving time by faster heating
  • Saving space through shorter drying distances
  • Saving energy through fast reaction times

What Is A Gas Catalytic IR Pre Gel Oven?

Pre Gel Oven

A Gas Catalytic IR Pre Gel oven is an oven that sits just in front of a conventional convection Oven. It is designed to allow the newly applied powder to gel and start the flowing process of the powder as it starts its chemical change under heat. It is not designed to completely cure the powder, as this process is completed in the convection oven.

Why use a Pre Gel Oven?

Pre Gel ovens can be used in the following instances:

  • When products have thick cross-sections, a Pre-Gel oven may be necessary for that extra boost before the convection oven.
  • If there is a need to increase line speed but your current convection oven just isn’t long enough, a Pre Gel oven will ensure increased line speed whilst utilizing the same overall length of oven.
  • If you are experiencing cross contamination of powder from the natural air movement associated with a convection oven, a Pre-Gel oven will set the powder and alleviate the problem.
  • If frequent color changes are required, a pre gel oven will enable shorter spaces between parts. This is due to the reduced cross contamination of powder caused by air movement within a convection oven.

How To Choose the Perfect Oven?

Perhaps the most important factor to consider when purchasing a new powder coating oven, is the initial Return On Investment (ROI). Then, the long term cost of operation. Do your calculations carefully, talk to as many different operators of the different technologies as you can. It is vitally important to run trials of your products. Do not forget to factor in the ongoing "Total Cost of Quality". Lastly do not forget to consider the overall reduction in your Carbon Footprint.
