As part of their continually developing capability, Wallwork Birmingham has installed the newest component cleaning equipment from Hockh. The washer will be used for the cleaning of ferrous and non-ferrous components prior to thermal processing using spray, vapour or a combination for optimal cleaning. The washer recycles solvent and even enables the oils removed from components to be recovered for reprocessing.
Serving customers in the higher technical spectrum such as aerospace, motorsport, oil, gas, and nuclear, Wallwork has a policy to continually invest for better process quality, reduced environmental impact and improved service delivery. “Effective and consistent heat treatment requires thorough component cleaning, but many traditional processes have drawbacks either because they use environmentally harmful products such as trichloroethylene or because they have the potential to damage the product. The newly installed Hockh washer cleans using perchloroethylene, the solvent that is used in dry cleaning. Solvent is recycled within the totally sealed process that is fully compliant with all EU emission regulations,” explained business development manager, Mark Ferguson.
Process consistency and quality are key considerations. Downstream thermal processing at the Birmingham Wallwork plant is certified to the AS9100 aerospace standard. The company has accelerated the approval process for the new cleaning system so that all key processes on this site comply with the standard.
The new cleaning machine has a capacity to process loads of up to 2.5 cubic metres. This can be made up of single items, large components or large quantities of small components in open mesh steel crates. The company has custom engineered these crates to achieve effective and economic component cleaning. “The process runs 24/7 and is suitable for a diverse range of components including castings, tubes, pressed components and machined parts. High volume throughput and efficiency results in spare capacity enabling us to offer local manufacturers a competitive sub contract de-grease service. This is backed by collection and delivery using a nationwide fleet of 35 company owned vehicles so that we can pick up, treat and to return components – often within 48-72 hours.” Mark noted.
