Profile: Lenton Treatments (Leicester) Ltd. is a chemical treatment service provider. We carry out processes like sodium hydride process, hot caustic bath, ceramic cores and machined castings. The sodium hydride process removes a heat treatment scale from most ferrous and non-ferrous metals. We clear iron, steel, bronze and aluminum castings of the final traces of foundry sand even in the most intricate cavities. We also remove rust and scale from castings such as hydraulic valve bodies, engine blocks & cylinder heads without damaging their machined faces.
