Engineering and Development are manufacturers of precision sand castings in aluminium, brass and bronze materials from our modern sand casting foundry based in Lymington, Hampshire, UK. We have a large well equipped sand casting foundry which can cater for technically challenging precision sand castings and standard cast products.

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 company’s 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. Separating the casting and machining processes can often lead to additional  cost and lead time, not an issue when using EDL.

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, with records kept for the life of the application on every component if required. 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 Siemens.

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.

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 the high precision sectors; the MOD, nuclear submarines and naval frigates. In addition, we supply for 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 for product evaluation and testing prior to mass production.

Copy Casting

EDL can cast precision replicas using original parts as pattern moulds. This technique is suitable for non-critical applications such as architectural items such as banisters and lamp posts.
