Portsmouth-based
Harwin, a manufacturer of high-reliability interconnects suitable for harsh environments, has invested in seven new CNC sliding head lathes fronm
Star Micronics GB Ltd. The addition of these machines adds significant capacity to Harwin's high-reliability connector manufacturing capabilities. The acquisition follows heightened demand for Harwin's connector ranges — notably Gecko — and an increase in R&D investment by the company.
This increased capacity will come into effect from January 2026, when the first two Star SL-7s are delivered to Harwin’s Portsmouth manufacturing plant. Capacity will further ramp up during the first half of the year, with additional new lathes being added in February, March and April.
Jon Churchill, Harwin’s chief operating officer, said: “Harwin continues to make significant investments in its UK manufacturing capacity, and the addition of these new machines represents a major milestone in the next phase of our expansion. Star’s high-precision sliding head lathes are integral to our HRi product range. By combining this advanced, reliable equipment with our highly skilled workforce, premium raw materials, and innovative structural design features, we can deliver critical components that underpin the exceptional ruggedness and performance of Harwin’s HRi products.”
The investment also strengthens Harwin’s long-standing partnership with Star GB, increasing the company’s total number of Star lathes to 56. Harwin’s expanded capability is supported by the broad range of Star technology already in use at its Portsmouth site. The facility operates SD-26 Type E and SR-20RIV Type B machines, which provide versatile, high-precision machining across mid-range diameters. These are supported by SL-7 and SR-10J models specialising in very small, accurate component production. This capability is complemented by several SW-12RII models, delivering high-speed twin-platen machining for complex, multi-feature components.
Precision and repeatabilityTogether, these platforms give Harwin a well-balanced mix of capacities, enabling efficient production of both miniature connector elements and more demanding geometries while maintaining the precision and repeatability required for its high-reliability product range.
Stephen Totty, Star GB’s managing director, said: “We are proud to continue our close collaboration with Harwin as the company expands its UK manufacturing footprint. Our technology is designed to deliver the precision, repeatability, and reliability that Harwin’s interconnects demand and we look forward to working with the company into the future.”
This latest phase of investment underscores Harwin’s commitment to maintaining world-class manufacturing in the UK and ensuring rapid, resilient supply for its global customer base. By combining advanced automation with in-house expertise, Harwin continues to strengthen its position as a trusted partner for mission-critical connectivity solutions worldwide.
