Die Casting


We offer Die castings to produce complex shapes with high precission and accuracy.

The die castings process is carried out by our partner foundries in Asia and complemented by stocking facilities here in the UK with a a fully inspected and tested casting, delivered to customers’ specifications.

We offer Pressure or Gravity die castings.

Pressure Die Casting

High pressure die casting is a means of mass-producing low temperature metallic components with a high degree of precision and repeatability.

Gravity Die Casting

Gravity die casting, sometimes known as permanent mould casting, is a means of die casting high-quality components in a range of low temperature metals.

Die casting is a manufacturing process that involves the use of molten metal to create parts and components.

It is a versatile process that can be used to produce complex shapes with high precision and accuracy.

The die casting process involves the injection of molten metal into a die or mould, which is then cooled and solidified to form the desired shape.

The die casting process offers many advantages over traditional manufacturing methods such as cost savings, improved accuracy, and faster production times.

The main advantages of the process include:

Fast Production

Our die casting process allows us to manufacture parts at speed with shorter lead times, ideal for high volume orders.

Intricate Castings

We have the capability to produce intricate castings with complex geometries and tight tolerances. Our experienced team can help you design and develop your product from concept to completion.

Dimensionally Accurate

Even when manufactured at speed, the die casting production process maintains reliability with parts remaining within their tolerances, with high-quality finishes.

Reliable Quality

We use the latest technology and processes to ensure that all our castings are of the highest quality, meeting all industry standards and regulations. Dean Group is a member of the Cast Metals Federation and BSI ISO 9001:2015 accredited, so you know you can trust us to guide you through your project and provide you with an excellent final result.

Multiple Finishes

We also offer a range of post-casting services such as machining, finishing, assembly, and testing.

These qualities make die casting an ideal choice for producing components for a wide range of industries, including automotiveaerospace, medical device manufacturing, and consumer electronics.

Both zinc alloys and aluminium are common metals used in die casting. Zinc is a ductile metal, producing casts with high impact strength and ductility. Aluminium die casting, on the other hand, produces parts with very lightweight, corrosion-resistant and good electromagnetic properties.

Zinc has a low melting point, making it easy to cast parts in multiple sizes and shapes. Castings made of zinc can be re-melted and recycled easily. Zinc alloys are also often used as die casting alloys for consumer electronics.

On the other hand, aluminium pressure die casting produces parts with very lightweight, corrosion-resistant, and good electromagnetic properties.

This makes die casted aluminium very suitable for parts used in several industries.

Alloying these metals with other metal elements increases the strength and hardness of the overall material.

Such alloys include, but are not limited to:

Nickel (high resistance)
Copper (increases the melting point)
Molybdenum (increases resistance to corrosion)
