Our quality procedures are approved to ISO 9001 standards and we offer an extensive range of destructive and non-destructive tests to demonstrate casting integrity.
Our technical team includes fully trained and qualified metallurgists who are responsible for material analysis, ensuring all material meets the chemical requirements of our customers’ orders. We use certified high quality ingots from reputable material suppliers. On melting, a melt button is taken and checked in one of our on-site spectrometer machines. If the chemical analysis of the melt is acceptable then the metallurgist will authorise for casting to continue. If the melt is outside the specification then different elements are added to bring the melt into the required specification. All melts are given their own unique melt number and records are kept by our quality department. This provides full traceability from start to finish.
We can offer the following tests and provide certification where required:
Meighs & Westleys supplies high-integrity sand castings in a wide range of heat, wear and corrosion resistant alloys, with a particular emphasis on defence and naval engineering standard materials.
Meighs & Westleys manages the rigorous testing process for such materials, which often includes 100% radiographic inspection, dye penetrant examination and third party witness inspection. Our range of materials includes nickel aluminium bronze, cupro nickel chrome, leaded gunmetal, aluminium silicon bronze and white metal.
Our most common materials are listed here but we are able to offer other materials on request.
Sand casting is a traditional but highly skilled casting method used to manufacture shaped parts in a cost effective manner.
Sand casting is so-named due to the use of bonded sand to create a mould into which molten metal is poured. The process is extremely versatile and allows for simple or intricate castings to be produced. Typically, sand moulds are produced using wooden pattern equipment which can be reused for repeat orders, or polystyrene patterns for single use.
Sand casting is a popular selection for pump and valve applications, where internal detailing and passageways can be achieved by adding cores during the moulding process.
