Die Casting

Die Casting Services

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

What makes die casting so effective is its efficiency and consistency. The molten metal flows quickly into the die, capturing every intricate detail of the design before solidifying. This speed not only results in parts that require minimal post-casting finishing, but it also enables high-volume production with tight tolerances.

At every stage of the process, from designing the dies to the final casting, our team ensures that quality and transparency remain paramount. We work closely with our clients, explaining each step and tailoring our approach to meet the specific demands of their projects. This commitment to clarity and excellence helps guarantee that every component we produce performs reliably in its intended application.

Types of Die Casting

Die casting processes generally fall into two main approaches, distinguished by how the molten metal is introduced into the mould. One method employs an external force to rapidly and uniformly fill the die, making it ideal for producing intricate components at high volumes. In contrast, another approach relies on the natural flow of the metal to achieve a smooth, consistent finish while minimising internal stresses. Each technique offers distinct benefits, allowing manufacturers to select the most suitable method for their specific production requirements.

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.

Process

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

The die casting process generally involves:

Die preparation
Metal preparation
Metal injection
Cooling
Ejection
Trimming

This process allows for the rapid production of complex components with high dimensional accuracy and excellent surface finishes. Instead of using wax patterns like in investment casting, die casting relies on durable dies that are designed to withstand the stresses of high-speed metal injection and rapid cooling.

Advantages

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

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 main advantages of the process include:

Fast Production

Our die casting process allows us to manufacture parts at speed with shorter lead times, which is 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 and high-quality finishes.

Reliable Quality

We use the latest technology and processes to ensure that all our castings are of the highest quality and meet all industry standards and regulations. Dean Group International 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 automotive, aerospace, 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 that are very lightweight, corrosion-resistant, and have 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 that are very lightweight, corrosion-resistant, and have 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)
