Screen changers with four screen cavities

Screen changers with four screen cavities consist of four independent breaker plates, each with openings of same diameter and screen pattern. The four screen cavites screen changer features, advantages, and applications are as follows.

Screen changers with four screen cavities applications:
Blown film and cast film, such as Bubble pack, Medical, Food Wrap
Sheet, such as Foam, Strapping, Plastic cardboard
Coating, for example: Hot melt adhesive
Pipe: Corrugated, Gas Pipe, and profile
Compounding: Master batch, filler
Wire and cable extrusion
Tubing: Medical, Industrial, Irrigation
Fibers: Monofilament
Blow molding
Pelletizing: strands and underwater
Recycling of most polymers

Screen changers with four screen cavities Benefits:
Possible for fine filtration, improve product quality
Enable precise processing for high quality production and reduce waste materials
Continuous operation
No interrupt during production
Reduced downtime & scrap
Reduced inlet pressure at extrusion die
Reduced temperature variations in the melt

Screen changers with four screen cavities Features:
Breaker plates move in the same direction one by one, improved filtration performance, convenient to clean.
Equipped with preheating and ventilation design to minimize the effect of possible temperature, pressure, melt flow fluctuation on polymer during screen changing process.
No rupture on film and filament production and changing the screen without stopping the production.

The rotation of specially treated alloy metal plates gives superior sealing ability and durability. Screen changers with four screen cavities have slight flow fluctuation during screen changing. It can guarantee a continuous and stable extrusion production.
