Neutralising Static in Automotive Plastic Extrusions
When the plastic leaves the die of the extruder, it is still hot. As the temperature falls, a static charge develops. This static charge attracts contaminants and can result in product rejects and shocks to operators.
Neutralising Static in Automotive Plastic Extrusions - Select a problem:
As soon as the plastic leaves the extruder and starts cooling, a static charge develops. When the item is cut or sawn to length, swarf is attracted and must be cleaned off prior to further processing.
4510 or 4800 Ionised Air Nozzles are suited to smaller applications, but either 5000 or 5100 Ionised Air Knives are efficient neutralisation and dust removal solutions on a larger scale.
When a high number of small plastic extrusions collect in a bin, the static charge accumulates. This will attract dust and can cause shocks to operators. It can even make the products jump out of the bin.
A medium range NEOS 12L, NEOS 20 or 3024L pulsed DC static eliminator positioned at the end of the conveyor and above the collection bin will neutralise the static charge and allow for safe handling of the product.
