I recently worked with a vinyl window and door manufacturer on a static issue they were experiencing during the manufacturing process. After the aluminum frames are cut to length they are placed into a holding fixture where the vinyl seals are placed in a channel inside the frame and clamped together. A machining tool then travels around the parts to trim and machine the excess material, creating dust and some small chips. They tried to vacuum the debris away but were still seeing some residual material cling to the surface due to static, which resulted in manual rework of the parts, slowing down the production cycle.
The customer was able to send a drawing of the holding fixture for reference and after reviewing the information, I recommended they use our 18″ Super Ion Air Knife Kit in this application. The Super Ion Air Knife provides a high velocity, laminar sheet of ionized air across the length of the knife. As the positive and negative ions neutralize the surface charge, the airflow is able to clean the part of the unwanted material so it can be more easily vacuumed away. Using the regulator included in the kit, they can reduce the supply pressure to control the outlet flow and velocity to an acceptable level that doesn’t disrupt the current process.
