Injection moulded pump rollers match machined counterparts for accuracy

22 February 2007

Quadrant CMS (Creative Moulding & Systems), and Micropump have succeeded in injection-moulding pumps-rollers for a high volume applications using Ertalyte TX PET-P. These parts were originally machined from extruded bar stock of the same material by Quadrant CMS’ sister company Quadrant EPP (Engineering Plastic Products). Since their original design and conception in 2003, the pump-rollers have been produced from Quadrant’s Ertalyte TX, a non-reinforced, semi-crystalline polyester (PET-P) with a solid lubricant filler. The material, which was chosen for its strength and stiffness, high dimensional stability, outstanding wear resistance and low friction coefficient, provides sustained performance under high-pressure and high-velocity conditions, and is suitable for applications involving soft metal and plastic mating surfaces.
Over a period of 14 months, Micropump and Quadrant EPP worked closely to develop the technology to injection-mould the pump-rollers from Ertalyte TX. The commercial results of this close cooperation are the injection-moulded parts which maintain the exceptionally tight tolerances (only 0.03mm on the internal diameter) of their extruded predecessors. They are produced by Quadrant CMS on a 16-cavity mould in Tielt, Belgium, and shipped to China for a simple post mould operation prior to assembly.
