HELIO®Clean is a combined conveying-/mixing and dedusting system to be mounted directly on the injection moulding machine/drying container and to feed virgin material and/or regrind.
Dust in material causes lowered mechanical properties of technical plastic resins, leads to problems with surface finish in case of transparent parts, to high rate of rejects basing on smudges or white/black dots in transparent injection moulding parts like for example optical lenses of PC and PMMA, to unstable processes due to impurities in the plasticizing unit and thus to high cleaning efforts with machine down times.
Professional cleaning of resins brings the quality to the original state again and optically perfect parts can be produced.
PMMA raw granules before and after dedusting
The resin/regrind is sucked by means of integrated conveying techniques into the dedusting chamber. The conveying speed is infinitely preselectable thus avoiding dust creation caused by abrasion. An exactly unchanging lot will be dedusted by air separating with ion shower then. The resin/regrind will be whirled just as high that it will not touch the sieve disc at dust outlet arising new dust.
During whirling up / circulation, ionisized air will be sucked through the material batch to be dedusted reducing the binding force between dust particles and resins as far as the dust dissolves and can be sucked out.
