RAS+REF

Automatic, self-cleaning, one and only

A screen changer which can handle any contamination types, with reduced losses and low maintenance costs, recognized as the cheapest in the market. Choosing the right screen changer is easy, just list:

  • the plastic material to be filtered;
  • extruder’s output production;
  • required filtration fineness (from 100 to 1500 µm are available);
  • Contamination (type & approx. percentage).

Description

ADVANTAGES

Definitely remarkable ones
All filtration finenesses are available, thanks to the supply of both punched or laser screens. Punched screens (i.e. starting from 300 µm) can last from min. 3 days to one week, with peaks up to 15 days. With laser screens (100 to 300 µm), the proven lifetime is one week up to 12 days; these can be then cleaned (to be reused) in a pyrolytic oven up to 4 times, obtaining a daily operational cost worth 30 Euro.

The discharge valve is not a discharge screw! For this reason our Screen Changers can process any contamination types, including very aggressive / abrasive ones like steel or sand, or high contamination rates, with no damage to the filter screen or structure, with limited material losses, thanks to the regulation of valve opening timeframe. FIMIC screen changers are the most solid and robust available in the market.

The total filtering surface can be compared to no other; 5 available sizes, up to a total filtering surface of almost 4.000 cm², obtained with only 1 screen: this allows no material degradations due to high operational pressures as the screen changer does not create a “blocking wall” through the melt passage; on the contrary, the melt flows without obstacles. For this reason the extruder´s performance normally increases after the installation of a FIMIC screen changer.

Operator’s interference is reduced to a minimum: no need for an operator constantly at the filter to continuously change screens (in some cases every 2-3 minutes because of high contaminations).

The time needed by only one operator to change the screen does not exceed 30 minutes.
