Baker Perkins' twin screw extruders and systems are specifically engineered for applications like the production of powder coatings.
Baker Perkins extruders cover a comprehensive range of throughputs - from small batch machines for laboratory and development purposes to continuous units with outputs reaching 2,900 kg per hour.
BAKER PERKINS EXTRUDER SYSTEMS KEY BENEFITS
Unlike other multi-purpose extruders, we specify motors with the precise power and torque, so output is maximised without wasting energy.
As power and torque are precisely matched, motor efficiency and lifespan are increased by reducing wear, while long-term maintenance costs are cut. The water-cooled motor is also quieter, cooler and easier to clean than the air-cooled alternative.
Easy-to-replace electric cast slab heaters and advanced water cooling within the barrel work simultaneously to provide accurate and consistent temperature control.
Quick start-up, reliable operation and rapid changeover keep operating costs low. Wear parts are long-lasting and easily replaced and, when combined with the ultra-low maintenance drive train, result in minimal maintenance costs.
Whether it is quick resin purges between batches, or deep clean purges between product changes, the automatic system reduces turnaround times, reduces labour requirements and minimises waste. The extruder software takes control to ensure repeatable, quality cleaning regimes. When integrated with upstream and downstream equipment, the system can take control in an emergency event, minimising product waste and equipment downtime; automatically returning to production once the issues have been resolved.
The HMI provides automatic management of formula settings and full visualisation of the process for exact, unvarying replication of product. Remote support enables off-site access for fault-finding and software updates.
All our Baker Perkins extruders are Industry 4.0 ready. Data collection records all process variables to combine with data from other machines, devices and sensors across a line, to facilitate informed and timely decisions regarding performance, efficiency or maintenance issues.
The MAX³ feed system successfully addresses the long-standing, industry-wide issue of restricted output and torque surges caused by material building up in the extruder feed port – when particles hit the intake screws and ‘bounce’ back into the infeed area rather than flowing into the machine.
Our patented system introduces a reconfigured feed port and unique screw designs to improve the flow of material into the extruder barrel and the air out of it. A major benefit is that lightweight, low density materials and fines are handled much more efficiently, eliminating the need for side-feeding and its unnecessary floor space, capital and running costs.
MAX³ is available on all HPX and MPX production and laboratory extruders; it can be retrofitted to top-feeding machines, and side-fed machines can be converted to top feeding.

Baker Perkins supplies a comprehensive range of production scale twin screw extruders for outputs from 100 kg small batch applications to 2,900 kg high-output machines.
The extruders have been specifically engineered to maintain consistent quality while keeping running costs low.
Unique MAX³ feed system for increased throughput
The patented Baker Perkins MAX³ feed system features unique feed port and screw designs to improve flow of material into the extruder barrel and air out of it, contributing to higher throughput. Lightweight, low-density materials are now handled more efficiently, eliminating the need for side feeding, reducing capital cost, floor space and running costs.
Consistent quality with low production and maintenance costs
High torque-capacity, high free-volume geometry and uniform barrel heating ensure that consistency is maintained under all operating conditions. Quick start-up, reliable operation and rapid changeover keep operating costs low. All wear parts are long-lasting and easily replaced and, when combined with the ultra-low maintenance drive train, result in minimal maintenance costs.
Easy to use and easy to clean
Straightforward set-up and adjustment means that very little operator attention is required for efficient running. The clamshell barrel can be opened quickly and easily for regular cleaning or changing the screws, while the open-frame design and high ground clearance mean that it is very easy to keep the area around the machine clean.

Baker Perkins high power HPX twin screw extruders deliver superior outputs on specialist applications from a smaller barrel, with reduced cost of ownership and machine downtime. Increased power and speed are the key attributes of the HPX range, achieved by full utilization of the motor through torque stability provided by the patented MAX³ feed system, and increased thrust capacity of the solid-shaft drive train. The extruders handle a full range of industrial applications, including the most intensive formulations.
HPX extruders retain all the latest features of Baker Perkins MPX series.
