Die Casting Services in the UK

Xometry UK works with partners with the latest die casting technology to deliver high quality, on-demand parts. Our typical tolerance accuracy ranges from ±0.0762 mm to ±0.127 mm for aluminium and zinc, depending on customer specifications.

Hot chamber casting, also referred to as gooseneck casting, is the most ubiquitous die casting process. In this process, the injection mechanism’s chamber is submerged in molten metal and the “gooseneck” metal supply structure guides the molten metal into the die cavity.

Cold chamber die casting is commonly employed to reduce machine corrosion. The liquified metal is loaded directly into the injection setup, removing the need to submerge the injection mechanism into the molten metal.

For high-volume production of comparatively complex metal parts, die casting is the most suitable manufacturing process. Die cast parts are manufactured using steel moulds that resemble those utilized in injection moulding. Instead of plastics as used in injection moulding, die casting involves metals with low melting points such as zinc and aluminium. Die casting’s popularity is a result of its accuracy, reliability, repeatability, and versatility.

In the die casting process, high pneumatic or hydraulic pressure forces molten metal into a steel mould/die. These moulds/dies can produce highly complex parts with high tolerance repeatedly. The Die casting process makes the most metal parts of all casting processes.

Die casting companies typically specialize in casting either magnesium, zinc or aluminium. Aluminium makes up approximately 80% of die cast parts.
