Ultramodern eco-friendly de-grease facilities are the latest addition to the developing capability at the Wallwork factory in Birmingham. The heat treatment specialist has installed the newest spray/vapour solvent cleaning equipment from Hockh for the cleaning of ferrous and non-ferrous components prior to thermal processing. Certification of the process to AS9100 is in line with other approved processes on the site and makes it fully compliant to the European aerospace quality standard.

Serving aerospace, motorsport, nuclear, oil and gas and other demanding industries, Wallwork continually invest to improve their process quality, service delivery and lessen their environmental impact. “Thorough cleaning is essential to achieving heat treatment goals. However, traditional processes such as the use of trichloroethylene, aqueous cleaning and tumbling all have drawbacks. The newly installed Hockh washer uses perchloroethylene, a solvent commonly used by dry cleaners, for effective cleaning on a closed process where solvent is recovered and reused,” explained business development manager, Mark Ferguson.

The new cleaning machine has high capacity and good cycle times. Single items or custom made baskets containing small components with a volume up to 2.5 cubic metres, can be turned around quickly. The process is suitable for castings, tubes, pressed components and machined parts. “The efficiency of this process means that we will have spare capacity and so will be offering local manufacturers a competitive de-grease service, backed-up by our dedicated collection and delivery fleet to return treated parts quickly,” Mark noted.

Wallwork heat treatment and hard coatings extend the service life and performance of engineered components. Providing national coverage, in addition to Birmingham, the company has comprehensive facilities for surface engineering in Manchester and Cambridge.
