Polar Technology, a leading engineering and manufacturing specialist in composite and metallic solutions, has expanded its production capabilities with the integration of a new three-spindle filament winding machine. The system forms part of a high-performance, CNC-controlled production cell designed to meet rising demand across the company's wound composites portfolio.
Polar now operates seven custom-designed, 4-axis filament winding machines equipped with closed-loop tension and temperature control. The investment strengthens the company's position in delivering lightweight, high-strength components for aerospace, automotive, motorsport, rail, and defense applications.
Polar employs both wet winding, where dry fibres are impregnated with liquid resin during winding, and prepreg winding, using slit tape or tow preg materials. Fibre types include carbon (standard and ultra-high modulus), glass, and aramid, while resin systems range from epoxy to Cyanate Ester and BMI, tailored to end-use requirements. Post-winding, components are cured in ovens or autoclaves for consolidation and performance assurance.
Product applications include transmission shafts for aircraft engines, actuation systems, rotorcraft, and automotive drivetrains; composite pressure vessels and tubes for storage and transport of high-pressure gases and liquids; and defense solutions using advanced tube designs with controlled thermal expansion properties.
Available in diameters from 10mm to 428mm (round tubes) and widths from 40mm to 300mm (square beams), the components are tailored for these high-demand applications. This expansion underscores Polar Technology's commitment to innovation in filament winding and reinforces its ability to supply advanced composite solutions to industries seeking efficiency, reliability, and performance.
