Conex^® Extruder

ADVANTAGES

¨ The one and same extruder is applicable for single- and multi-layer products of a wide range of polymers

¨ Minimal equipment investments and elimination of auxiliary processing steps like compounding

¨ Short residence time (RT) and -distribution (RTD) allow higher process temperatures without degradation

¨ Short ramp-up/down time giving minimal scrap amounts

¨ No melt separators in dies providing seamless products

¨ Simple and low cost dies for product sizing—one and the same die for single– and multilayer products

¨ Extrusion at low die pressures - giving light weight solid products of compressive materials like wood

¨ Fast material, color, filler etc. change on-line; no “dead spots” in the extruder nor in the dies

¨ Telescopic extruder frame means short cleaning times - and safely while there are no lifting operations

¨ Excellent temperature control of melt for sensitive polymers (e.g. HFFR, ECCOH) due high shear rate in solid bed caused by high circumferential velocity and reducing shear rate as soon as melt is formed

¨ Direct injection of liquid processing additives (e.g. peroxide) and gases (e.g. N₂, CO₂)

¨ Removal of moisture and volatiles while extruding wet materials

¨ Superb on-line mixing capacity with SuperMixer and UniCone rotor/stator geometries for extremely well dispersed and homogenous melt

¨ Negligible die pressure variations (no pumping) for manufacturing uniform and close tolerance products

¨ Adjustable flight clearance between the rotor and stators from min. 0,2 mm upwards

¨ Grinding of crushed materials and other larger particles on-line by the extruder

¨ Compact design with space savings

¨ Orientation of fibres for extra strong products and uniform characteristics crosswise (e.g. wood, LCP, glass)

¨ A hole in the middle of the extruder in line direction for coating objects or internal cooling

¨ Low noise (<80 dB) and ease of operating
