Our new High Power HPX twin-screw extruders deliver superior outputs on powder coating and specialist chemical applications from a smaller barrel, with reduced cost of ownership and machine downtime.

Increased power and speed are the key attributes of the new HPX35 and HPX45 extruders, achieved by full utilisation of the motor through torque stability provided by the patented MAX³ feed system, as well as the increased thrust capacity of the solid-shaft drive train.

The extruders can handle a full array of powder coatings and toners, including the most intensive formulations. The MPX series of extruders will be retained for powder coating applications requiring through-shaft cooling.

The HPX range retains all the latest features and benefits of the MPX range. As well as the patented MAX³ feed system, these include a hi-cool barrel that increases efficiency and allows lower melt temperatures; a split stuffing box for increased access; a pivoting main feeder for easier calibration and emptying; and purge feeders for quicker turnarounds between batches. Noise is minimised by using water cooled main drive motors; a hi-cool discharge adaptor and non-stick coating minimise product hang-up at discharge.

The MAX³ feed system incorporates a fundamental re-design of the extruder intake feed port and screws. It improves the flow of material into the extruder barrel and the air out of it to eliminate material build up in the extruder infeed that leads to restricted output and torque surges.

The system brings proven 40% up to 100% throughput benefits; top feeding also creates improvements in operation that significantly reduce cost-of-ownership compared to conventional side feeding.
