Die Casting: Overview
Die-casting is a process that shapes metal into desired shapes and sizes. This method uses non-ferrous materials that are melted in a furnace. Depending on the production needs, the molten metal is poured into a multi-cavity or single-cavity mold using high pressure.
It allows the molten metal to cool and harden into the exact shape of the mold’s design. The die cast part is ejected from the mold and creates complex metal parts with detailed shapes, tight dimensional accuracy, high strength, and smooth surfaces.
After die-casting, parts may need extra processing such as CNC machining or surface finishing to ensure they meet strict tolerance and quality standards.

Types of Die-Casting Service We Provide
DSR offers a wide range of die-casting services to support your projects and manufacturing needs.
In this process, we melt the raw material in an independent furnace before the casting process begins. Then, we will pour it in the cold-chamber where a piston will push it into the mold using high pressure. It is typically used for creating aluminium parts for aircraft, electronic housings, and more.
It is known as gooseneck casting. The furnace that melts the metal is directly connected to the die-casting machine. A piston draws the molten metal from the furnace. Then, forces it into the die cavity. This ensures the molten metal fills every intricate detail of the mold. It also offers fast cycle times and efficient high-volume part production.
It is a process where metal is heated until it reaches a paste-like state. In this condition, the metal is carefully injected into the mold at a slower pace. This results in parts with fewer internal air pockets, greater strength, and smooth surface finish. It is commonly used to create aluminium and magnesium parts.
Popular for its other name called lost-wax casting. A wax model is created in this process to make the mold. This is where the molten metal will be poured during the casting process. It is best for low volume production of parts with tight tolerances.

Aluminum Die-Casting
Most die cast custom parts are made from aluminium materials. This material has a high melting point. Therefore, making them suitable for the cold-chamber die casting process. Aluminium die cast parts have excellent strength-to-weight ratio, lightweight, and corrosion resistance. It includes electronic components, airplane parts, thin-walled car parts, and more. DSR die casting service can process various aluminium grades including:
- 6063
- Pure Aluminum
- ADC10
- DM6
- HA4
- ADC12
- HA6, and more
Magnesium Die Casting
Magnesium is a material characterized by their good machinability and high strength. This makes them suitable for the die casting process to create a wide range of components such as housings for handheld devices, automotive, electronics, EMI shielding, and more. At DSR, we use various magnesium grades for die casting process:
- AZ91D
- AM60B
- AM50A
Zinc Die-Casting
This material is the easiest to cast since they have low melting points and flows well in the mold. This makes it perfect for the hot-chamber die-casting process. Zinc also cools and hardened faster allowing quick custom part production rates. Zinc die-casting can achieve thin wall parts with tight tolerance and intricate shapes. Die cast Zinc parts have high strength and excellent dimensional stability.
Our die casting process is suitable for different Zinc grades including:
- Zamak2
- Zamak3
- Zamak5
- Zamak7
Surface Finishing Options
Surface finishing and post-processing are the final step in our die-casting process. This removes defects in the part surface and enhances overall appearance, functionality, and properties.
This is the basic finish applied directly after casting. It provides a relatively smooth surface with only minor tool marks. As-cast finishing is used for non-cosmetic applications where appearance is not a priority.
Anodizing is a popular surface finishing for aluminium cast parts. It enhances corrosion resistance, improves wear resistance, and adds an attractive finish. Available in a range of color options to improve overall appearance.
We use this finishing process on aluminium and zinc components. It creates a protective layer that increases corrosion resistance. This also serves as an excellent pre-treatment before painting or applying another coating.
Painting adds color to the die cast parts for branding or design purposes. This also offers extra corrosion protection and improved wear resistance.
Also known as abrasive blasting. This process cleans the die cast part surface by removing impurities, rust, or scales. It produces a uniform matte texture that improves appearance and adhesion of paint or other coatings.
