Die Casting Main Benefits
Efficiency
Rapid production cycles make die casting ideal for large volume manufacturing.
Precision
Produces parts with high dimensional accuracy and smooth surfaces, minimizing the need for machining.
Strength
Castings are durable, with excellent mechanical properties, suitable for demanding applications.
Zinc: The easiest metal to cast; high ductility; high impact strength; easily plated; economical for small parts; promotes long die life.
Aluminium: Lightweight; high dimensional stability for very complex shapes and thin walls; good corrosion resistance; good mechanical properties; high thermal and electrical conductivity; retains strength at moderately high temperatures.
Magnesium: The easiest metal to machine; excellent strength-to-weight ratio; lightest alloy commonly die cast.
Copper: High hardness; high corrosion resistance; highest mechanical properties of alloys die cast; excellent wear resistance; excellent dimensional stability; strength approaching that of steel parts.
Silicon tombac: High-strength alloy made of copper, zinc and silicon. Often used as an alternative for investment cast steel parts.
Lead and tin: High density; extremely close dimensional accuracy; used for special forms of corrosion resistance. Such alloys are not used in foodservice applications for public health reasons.

Die Casting Process
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.
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.
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.
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.
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.
Components for the automotive industry, such as gearbox cases and engine mounts.
Enclosures for consumer electronics, like mobile phones and gaming consoles.
Parts for home appliances, such as gas burners and connectors.
