Single plate screen changer: Plate and screen changer are all made 38CrMoAl alloy steel.
Group leak-protection sheel set of changing reseau: It is suitable for the filter of high transparent, high viscidity, fissility, and plastic of high molecular quantum.
Characteristic: The mould group leak-protecition steel set of changing reseau filter fleetly, which can dismantle and fix the tatty steel set neatly needn't process separately.



Single column plastic extrusion screen changer
1. Come with bulit-in sealing devive to ensure sound tightness and allow for mass production of any polymers. Capable of being coupled with extruders of various specifications.
2. Screen -changing time less than 2 seconds. The filtering area may vary between? 30mm--?
250mm.
3. Come with grinding--resistant, pressure--resistant and high precision filter to ensure maximized filtering area and optimized filtering results.
Its performance will not be compromised when the pressure is kept between 25--30Mpa and temperature around 300° C.
