EDL specialise in the manufacture of complex precision castings in various aluminium’s, bronzes and brasses, and ship worldwide. Our batch sizes range from 1 off to larger batch quantities. We offer three primary casting processes:

  • Precision Sand Casting
  • Investment Casting / Lost Wax Castings
  • Gravity Die Casting

We work in all grades of aluminium alloy, including specialist aerospace aluminium alloys and have the support of a dedicated quality assurance department equipped for smelt analysis, x-ray crack detection and dye penetrant inspection of precision cast aluminium components, along with precision bronze and brass castings.

Over the years EDL has manufactured specialist precision castings for the defence, aerospace, marine, commercial, automotive industry sectors, as well as for the architectural and art sectors. We also offer in-house design capability for lost wax moulds, die castings and sand core precision aluminium castings.

Aluminium Sand Casting

We can offer a fast turn around on aluminium sand castings with the added benefit of a direct line service for machining and inspection. With over 40 years experience in the production of sand moulds as well as copy casting we have the expertise and experience to handle most aluminium sand casting jobs with a capacity of up to 200kg. With four furnaces and ample space we are ideally suited to both one off as well as high volume production work of precision castings.

Aluminium Gravity Die Casting

For higher volume production work we can undertake aluminium gravity die casting utilising either customer mould tools or mould tools designed and manufactured in-house by EDL.

Our facilities are equipped for the production runs of between 50-500 item batches with in-house sand core manufacture for additional detail.

Aluminium Investment Castings

Since 1990 EDL have offered specialist investment casting services using lost wax moulds for precision aluminium casting, mainly for the aerospace sector. Aluminium investment casting is ideally suited to work that requires finely detailed castings, which when combined with metallurgical smelt analysis and NDT flaw detection, such as turbine housings, lightweight aerospace instrument enclosures, engine components and nuclear energy applications.

Aluminium Casting Alloys

EDL have years of experience in the production of aluminium castings for both general work such as architectural castings as well as specialist precision components with quality control applied and materials traceability. We can manufacture precision cast components with a wide range of aluminium alloys ranging from standard LM4 and LM6 materials through to complex alloys for the aerospace industries such as:

  • UNS A13600: thin walled applications
  • UNS A03900: high wear resistance for mechanical parts, cylinder blocks, air conditioner pistons etc
  • UNS A14130: high corrosion resistance
  • UNS A14440: excellent impact absorption, ideal for railway locomotive parts, turbo chargers etc
  • UNS A05350: shock & corrosion resistance with dimensional stability, used for optical equipment
  • UNS A02060: high tensile & yield strength ideal for automotive & aerospace applications
  • UNS A02220: primarily a piston alloy but also suited to cylinder heads & valve tappet guides
  • UNS A02420: air cooled cylinder heads & high performance pistons
  • UNS A03330: low cost alloy for engine parts, flywheels and regulator parts etc
  • UNS A03550: for pressure applications such as pump bodies and liquid cooled cylinder heads

We take great care in delivering top quality precision aluminium castings to customer specification on time and at competitive prices. Our primary strength in relation to the casting of specialist aluminium alloys is our spectrographic smelt analysis capability, this means full traceability can be assured with all castings having the correct chemical composition just prior to production.

Quality Assurance

EDL hold the EN 9100 / AS 9100 accreditation and operate a dedicated quality control service for the manufacture of casting products and components. The inspection department which is staffed by five permanent highly skilled and experienced engineers, is fully equipped to handle all dimensional inspection processes, as well as facilities for non destructive testing as below.

Depending on your requirements, we can offer a wide range of inspection programmes to suit the product.
