EDL have been manufacturing precision aluminium castings from our modern foundry which consists of investment casting & lost wax casting processes. This is accompanied by our precision sand casting & gravity die casting service, which is offered to companies in the UK and internationally.
With a steady investment in plant and process control systems, the business has grown steadily, providing a diverse range of market sectors with investment & lost wax precision castings. We are a key manufacturer of precision castings to the aerospace, marine, defence, commercial, automotive and architectural industry sectors. EDL do have the capability within the company for producing high quality castings & components, machined parts, complex components and assemblies for a wide range of other sectors, if required.
Investment casting, also known as lost wax casting, offers the potential for finely detailed precision castings with complex internal structures suitable for the most demanding of industries. The investment casting process is complex and involves a number of stages as detailed below:
EDL maintain very high standards of quality control throughout all stages of casting manufacture. Combining our years of experience with the latest technical capability and an array of flaw detection techniques, metallurgical controls and CMM, we are able to offer investment castings for the most challenging performance criteria.
Quality of finished castings is dependent entirely on the quality of the waxes and coatings used. We use only the finest new filled, emulsified and straight pattern waxes together with high grade ceramic slurry. Moulds are thoroughly cleaned and internally treated with a release agent prior to coating to ease production and produce parts of high quality.
