Aluminium Diecaster


What we do:

Sarginsons is one of the few European companies to offer gravity die-casting,  sand-casting, and low pressure die-casting in a single foundry.

This means being able to prototype designs using sand-casting until the design is perfect, then moving on to production using gravity or low pressure die-casting.

Die casting is a process where molten metal is forced under high pressure into a mould cavity. The mould is created using two hardened steel dies which have been machined into shape and which clamp together to create a cavity inside. Most die castings are made from non-ferrous metals, such as zinc, copper, aluminium, magnesium, lead, pewter and tin-based alloys

Sand casting is a metal casting process where sand is used to form the mould in specialised factories called foundries. The large majority of metal castings are produced by the sand casting process.

Moulds made of sand are lower cost, and sufficiently heat resistant even for steel foundry use.

Why we do it:

Since its discovery 5000 years ago metal casting has played a critical role in the development and advancement of human cultures. 

And to this day it continues to play a significant role in our lives.

The components Sarginsons make are critical elements in car engines, suspension systems, gear-boxes, ducting systems, oil control valves, to name a few. The hidden from view parts you only see when you lift the bonnet or peer underneath. Components that are critical elements in allowing us to drive, build, diagnose illnesses, and keep warm.

The company prides itself on delivering top-quality parts as befits the respected manufacturers who are its clients.

Developing these components with a client relies on close cooperation between teams - sharing ideas and pushing the boundaries of what can be achieved within the casting process.

Everyone at Sarginsons takes pride in being accountable for the final product.

The People who do it:

Sarginsons understands well the importance of its growing team of engineers, consultants and casting specialists. Their skill and knowledge are essential to the design and manufacture of elegant components and the company's research into new casting technologies

Into the Future:

Being lean and quick has never been more important. This industry, like many others, is now facing an unprecedented challenge.

To ensure it is well prepared to stay ahead of the competition the company opened its own dedicated Technology Centre.

The facility puts the focus on the use of the latest CAD technology, which produces detailed simulations resulting in more comprehensive data. Together these allow client’s engineers to make much more informed decisions about the casting process.
