RAS THE ONE OF A KINDSCREENCHANGER

RAS is the filter that made FIMIC known across the whole world, our flagship product, and we’re especially proud of it since it represents an important achievement for our company. As you read this, we’re approaching the total of over 300 RAS filter units delivered and installed worldwide, from South America to New Zealand. This feat is attestation of FIMIC’s twenty years expertise in screen manufacturing, and also of the quality of Italian craftsmanship, further boosting the importance of Made in Italy on the international scene.

What is RAS’s secret?

The ability to manage arbitrary melt contamination levels, all the while guaranteeing low amounts of waste and low maintenance costs. This is due to RAS’s high customizability, that allows it to fit to your needs concerning input material, hourly yield, level of filtration and kind of contamination.


How does it work?

Any contamination the filter collects is scraped from its surface by two blades, and then gathered by the blade-holder. Finally, anything harvested is automatically ejected through the front valve.

Another important feature is the possibility to determine a pressure set-point (in pressure mode) with nothing more than a few taps on the touch screen, so that once such level is reached the blade holder (running at adjustable speed) will proceed to gather the contamination, opening the front valve only on a full cycle. In the event of a particularly contaminated input material, the filter cant be set to work in continuous mode: the blade holder will keep on scraping, while relying on temporized valve openings to discharge as needed.

FLEXIBLE

The high number of filters we installed gives us the know-how to fit our RAS units to the widest range of necessities and possible applications: be it blow or injection, it will handle any type of moulding. It is furthermore possible to adapt it to single-screw and double-screw extruders alike, thus covering each and any filtration necessity.

RESISTANT

RAS is doubtlessly the sturdiest filter on the market! Its non-auger valve allows it to process any kind of contamination, including the most aggressive ones like iron and sand with no damage to the screen and screen changer.

ADAPTABLE

Being able to equip both laser and punched filters, RAS can provide any level of filtration. A punched filter has a working life of 3-7 days, while a laser one can reach a 12 days one, with the added possibility of being cleansed in a pyrolytic oven up to four times for increased lifetime, further reducing costs.

BIG

The size of RAS’s filtering surface is on a league of its own! Adaptable to various use cases, this key characteristic allows RAS not to degrade the processed material, which is able to flow unhindered. This is how RAS will increase your hourly yield!
