With today's ever increasing demands on manufacturing processes which require increased dimensional accuracy, improved productivity and process flexibility, the advantages of extrusion through a gear pump appear to point to the indispensable inclusion of gear pumps in the next generation of extrusion equipment. Whilst certain limitations in single screw direct extrusion (such as dimensional stability) can only be inadequately compensated for and others (such as throughput improvements) can only be resolved by increasing extruder size, inclusion of a gear pump either as retrofit or included in new equipment offer great potential advantages. These include: 1. Profile Extrusion with Dimensional Stability and thus Reduction in Scrap 2. Increased Throughput and Higher Production Capacity 3. Greater Process Flexibility 4. Mechanical Advantages 5. Commercial Advantages.
