A manufacturer of laminated floor planks was having issues with defects prior to packaging.  The planks were made from a high-density fiberboard as the core with a top layer of a picturesque image, then sealed together.  They were getting fine material that was stuck on the surface, making them defective.  The issue was caused after the cutting process.  The fine debris remained on the surface and when the image or the sealing material was applied, it could be seen.  They tried wiping, but the solution caused scratches.  They tried blowing the surface to clear the debris, but due to the static, it would not fall off easily.  They required a good solution to improve the cleaning without slowing the process.  EXAIR’s Static Eliminators are a great product for industrial processes like this. 

In looking at the process, I recommended two pieces of a model 112242 42” Gen4 Super Ion Air Knife Kit.  The planks could come out in two spots or four spots.  (Reference photo above) To reduce compressed air usage, they could turn on or off which side is needed.  The customer asked about the mounting and compressed air attachments.  I mentioned the proper setup for the most effective blowing.  As a benefit, I offered a plumbing kit to help with the compressed air connection.  The PKI option, or Plumbing Kit Installed, has the proper amount of connection to the Super Ion Air Knife to allow for an even force across the entire knife.  I upgraded the model number with the PKI option to a model 112242PKI. 

This kit will include the Gen4 Super Ion Air Knife with a PKI, a power supply, a filter, a regulator and a shim set.  The Gen4 Power Supply creates both positive and negative ions to remove any type of static.  The filter will remove bulk liquids and debris from the compressed air to keep the product clean and to optimize performance.  The Regulator is used to control the force.  This helps to not overuse the amount of compressed air required for the job.  With a regulator, you can make fine adjustments to get the proper amount of air.  For coarse adjustments, you can change shims to increase or decrease the force.  The customer was happy with the properly sized components to operate a non-contact wiping with the Gen4 Super Ion Air Knives. 

Once installed, their defect rate almost dropped to zero.  They were very happy with the cleanliness of the planks; they decided to purchase six more units.  They could place them in different areas of the lamination line to ensure a clean surface.  EXAIR manufactures a variety of Static Eliminator products.  If you feel that static is an issue in your process, you can always contact an Application Engineer to help you.  For the company above, they were “stepping” high.
