Why Die Casting?

Die casting provides parts which are have the accuracy and detail of plastic injection moldings but with the superior physical properties of metal. In summary die casting offers these advantages:

· Cost effective piece price compared with machining

· Production lead time short

· Casting process ensures consistent quality

· Complex net-shapes can be cast

· Parts have better rigidity and the look and feel of metal

· Meet moderate to high-strength performance needs

· Moderate to high impact and dent resistance

· Excellent sound damping properties

· Inherent EMI shielding

· Good pressure tightness

· Accepts high quality surface finishes - painting plating or anodizing

· Recyclable


How does die casting work?

The die casting process involves several steps, including mould design, metal preparation, injection, casting, and finishing.

Step 1 – Mould design

The initial step in the die casting process is creating a mould called a die. This mould is usually made from steel or aluminium and is designed to withstand the high temperatures and pressures of the die casting process. 

The mould design begins with developing a CAD design of the required mould. This design is then used to create a mould by CNC machining, which is further used in the casting process.

Step 2 – Metal preparation

The next step is to prepare the metal for injection. This metal is typically an alloy, such as aluminium, magnesium, or zinc. The metal is melted in a furnace and then poured into a ladle.

Step 3 – Injection process

Once the metal is in a liquid state, it is injected into the mould under high pressure. The molten metal fills the mould cavity and cools to create the desired shape.

Step 4 – Casting process

After the metal has cooled and hardened, the mould is opened, and the part is ejected. Ensure that the part has cooled entirely before handling to avoid any potential injuries.

Step 5 – Finishing process

The final step in the process is to finish the part. Surface finishing plays a vital role in die casting, as it can impact the durability and function of the part. Standard finishing processes include anodizing, powder coating, wet plating, and many more.
