Sand Casting Benefits

Sand casting is an attractive option under certain circumstances. Benefits include ease of manufacture in comparison to machined components; speed of manufacture; lower cost of tooling in comparison to die casting and investment casting; and metallurgical properties of finished components which lends advantages towards certain industries. 

Benefits of using EDL for your sand casting include the companies years of experience in the foundry business, a direct line service from foundry to machine shop and our in-house quality & inspection capabilities.

Direct Line Service

Because of our direct line service, foundry and machine shop under the same roof, EDL are in a position to guarantee lead times with greater accuracy over other companies that should there be an issue with the machining of the component would have to wait for a new casting to be produced and delivered, at extra cost and time. With EDL, should production issues result in scrap the job is easily replaced quickly and at no extra cost.

High Value Engineering Components

EDL has over 30 years experience in the provision of high value engineering metalwork components to the most demanding sectors, including aerospace, defence, commercial, automotive and marine. Full traceability can be offered with engraving, documentation, and associated flaw detection on every component if required. With record keeping kept for the life of the application, for example, life of an airplane. Our in-house spectrographic capability means we can ensure melt quality prior to pouring, adjusting elements such as manganese, as required.

Some of our approvals, include Eaton Systems, Flight Refuelling, Cobham, BAE Systems, Ultra Electronics and Sieman's.

Architectural Metalwork

EDL offer cast architectural metalwork and have recently brought on board the key personnel of GF James Pattern makers giving them the capability to offer specialist Bronze castings, including plaques, street furniture, railings, balustrades and stairs. You can read more about EDL's architectural metalwork services here.

Marine Castings

Based in the UK's yacht capital, Lymington, close to Southampton, Portsmouth and the Isle of Wight EDL have developed considerable experience in the production of marine castings for both the high precision sectors, the MOD, nuclear submarines and naval frigates. As well as commercial and private projects, such as tall ships and historic rigged vessels private luxury yachts and power boats.

EDL have experience in the provision of propellers, general chandlery, including cleats and boom ends, cannon and the naval crowns which are fitted to the top of every Royal Navy vessel.


Using the highest grade sands and bonding resins we can undertake cast prototypes with the equivalent surface finish to that of die casting and investment casting, ideal of product evaluation and testing prior to mass production.

Copy Casting

EDL can cast precision replica's using original parts as pattern moulds. This technique will generally produce slightly undersized castings although for non critical applications this is not always a concern, for example, copying architectural items such as banisters and lamp posts.
