What we see

Recycling melt filters, also known as laser filters, are essential in improving melt quality and throughput in post-consumer recycled material processing. We frequently receive filters from top manufacturers like Erema, Fimic, and Maag/Ettlinger, plugged with a combination of organic and inorganic contaminants from the recycling stream. Organic buildup can often be addressed with high-temperature oxidation, but standard furnace burnouts risk damaging the delicate screen materials and does not address the inorganic contaminants that can remain in the precision pores of the screen.

When the contamination includes inorganic substances like silica and aluminum, high-temperature methods alone prove ineffective, leaving the filter’s laser-etched pores blocked and reducing overall filtration efficiency. This buildup impacts the performance of recycling equipment, requiring specialized cleaning methods to fully restore the filter’s functionality.
