UK based Aluminum casting specialist Alucast has invested more than GBP 200,000 is launching a new specialist department as it continues to recover from the pandemic. Alucast, which employs nearly 100 people at its factory in Wednesbury, has secured a number of new wins with major car makers thanks to its ability to provide simulation, casting, machining, and the latest testing facilities. Now the latter has been strengthened even further after the company invested more than GBP 200,000 to create a new dye penetrant service, a form of non-destructive testing used to assess structural vehicle components and other parts for cracks.Cast and machined parts are cleaned and treated with a special, coloured penetrant liquid, which searches out minute cracks in the surface of the components. The parts are then left for a period of time, so that the penetrant can soak into any cracked areas, after which they are washed clean, which removes the liquid from the surface. A developer is then used on the part and essentially draws out the penetrant from the crack to reveal a coloured line if a fault exists. If cracks are evident, the part is scrapped.Alucast offers sand, gravity and high and low pressure casting to a client base that spans automotive, construction products, electrification and hydraulics.
