Technology / product information

When it comes to aluminum components that require complex shapes and high dimensional stability, aluminum die casting is one of the most widely used solutions in modern manufacturing.
🔹 When high precision and mass production are required
Aluminum die casting uses heat-resistant steel molds and high-pressure casting machines (typically 1,000–2,000 bar) to inject molten metal into the mold cavity.
This method allows the production of parts with:
- High dimensional accuracy (tolerance: ±0.05–±0.1 mm)
- Smooth surfaces with minimal burrs, reducing post-processing
- Consistent quality between products in the same lot
It is ideal for components that require uniform quality and high-volume production, such as motor housings, pump bodies, structural frames, and electrical or electronic parts.

🔹 When complex, thin-walled parts are needed
Aluminum die casting allows the forming of thin-walled components (1.5–2.5 mm) and complex designs that include reinforcing ribs, technical grooves, and assembly holes.
Compared with CNC machining, this method provides:
-Less material waste for thin or hollow parts
-Shorter production time since the mold determines the shape
-Higher productivity by casting multiple parts in a single shot

🔹 When lightweight, strength, and heat dissipation are required
Key features of aluminum alloy castings:
Lightweight (about one-third the weight of steel)
High tensile strength (200–400 MPa)
Excellent heat dissipation and corrosion resistance
Therefore, it’s ideal for components that require both rigidity and durability while minimizing weight, such as motor housings, robot bodies, electronic parts, and lightweight industrial equipment.
