The past 12 months saw Impregnation Services Limited grow from strength to strength. Some key events for Impregnation Services Limited in 2022 include:

  • Acquisition – Impregnation Services Limited demonstrated its commitment to continued growth and investment in its capabilities and production capacity through the acquisition of ‘Midland Impregnation’, their plant and equipment.
  • Commissioning & Integration – Impregnation Services Limited was involved in the commissioning of used refurbished Impregnation equipment in a prestigious tap manufacturer, and supported the integration and automation of the project in their European factory.
  • Specialist Impregnation Module Development – Further, Impregnation Services Limited worked with a new customer to develop a machine for the impregnation of casting cores to increase stability and reduce failures. The unique stainless steel vacuum transfer module was designed in house by ISL and its small footprint made it easy to install and maintain.
  • Equipment Refurbishment – We refurbished another MecWash ‘Midi’ (Duo 400) Industrial Aqueous Parts Washing Machine with a 200Kg load capacity to an exemplary standard as part of our growing used equipment refurbishment and resale service.
