The majority of polymer films are manufactured by film blower extruders (blown film extrusion). Film blowing process: A single screw extruder is used to melt the polymer and force it into a tubular die. Air is blown into the centre of the extrude tube and causes it to expand in the radial direction. Adjustments to wall thickness and diameter are made in this continuous bubble or tube.
Extension of the melt in both the radial and down-stream direction stops at the freeze line (frost line) due to crystallization of the melt. The nip rolls collect the film, as well as sealing the top of the bubble to maintain the air pressure inside. This is used extensively with polyethylene and polypropylene.
Our latest GU Range is manufactured with a larger drum. The size ranges from an 18.5kw motor to an 110kw motor depending on the expected output. Plastic recyclers often refer to them as plastic densifiers. These industrial machines are used in the recycling process to densify PE/PP and also assists with drying rigid polymers.
This process occurs after the plastic has been washed or if the plastic is already clean and granulated. We also have introduced an agglomerator/compactor that is part of the extruder where the process of both agglomerating & extruding is combined.
It is available in three granulator blade configurations, namely the straight blades, staggered blades and V shape blades. We have also introduced a RS-1000 and RS-1200 Granulator, cutting from 1-2 tons/h.
Horizontal balers are reliable and easy to use when compacting large volumes of waste. Manual-tie ,horizontal balers, also known as semi-automatic, horizontal baling machines can produce a bale from 200-850kgs with sizes up to 1100mm*1100*1200mm.
