fusionX Development Announcement: High-Temperature Extrusion Redefined
Announcing the fusionX — Noztek's high-temperature extrusion platform designed for processing ultra-high-performance polymers at temperatures up to 600°C.
The Brief That Started the fusionX
The fusionX began as a response to a consistent set of requests from Noztek's research customer base. Researchers working with PEEK, PEKK, PEI, and novel ultra-high-performance polymer systems were finding that existing desktop equipment could not reliably process their materials. The barriers were thermal: the barrel temperatures required exceeded what conventional heating systems could sustain continuously.
The question we set out to answer was: what would a machine designed from the ground up for high-temperature processing look like? Not a standard extruder with a more powerful heater added — a clean-sheet design optimised for 400–600°C operation, with every component selected for performance at those conditions.
Engineering the Thermal System
At 600°C, most components used in standard extruder construction are at or beyond their operating limits. The barrel and screw are machined from specialist high-temperature alloy steel grades. The heating elements use wire alloys selected for thermal output and service life at the operating temperature. The thermocouple specification and placement were determined through thermal modelling and validated against physical testing.
Motor and Drive Selection
The fusionX uses a servo motor drive system — a decision that predated the broader Noztek servo transition. Open-loop DC motors cannot maintain stable screw speed against the high torque demands of processing ultra-high-viscosity melts at high temperatures. The servo provides both the torque reserve and the speed regulation needed for consistent output.
Target Applications
The fusionX is designed for researchers who need to process polymer systems that no other desktop equipment can handle — PEEK and PEKK for biomedical and aerospace applications, novel ultra-high-performance thermoplastics under development, and high-temperature composite systems that require sustained operation at temperatures previously achievable only on industrial-scale equipment.
