Generally speaking: No screen filter device (No screen mold) is coarse filter, it is applied for the first stage of waste plastic granulating (The Double stage granulating machine).

With the advantage as follows:
1) No need change the screen, save labor cost and labor intensity is reduced

2) Reduce the consumption of conventional screen

3) To ensure the continuity of granulating and rise the capacity of plastic granulating machine

4) Formed the melt pressure at the nose part and improve the efficient of material plasticizing

With the shortage as follows:
1) The pressure is high in nose part of extruder while being fed low melting index plastic material

2) The filter mesh can’t be too high

3) Little aluminum foil will be through while extruding Aluminum foil film

Although there are both advantage and disadvantage of No screen filter, the advantage of No screen filter used in Plastic Extruder is obvious. No screen filter is the direction of plastic impurity filtration of plastic granulating. It will be better by improving innovation during the production and study.
