PRESSURE CASTING(Metal-Mold / Sand-Mold)
🔩 Pressure Casting
(High-Pressure Casting Process)
Pressure Casting is a metal casting process where molten metal is injected into a mold under high pressure.
It is commonly used for mass production of precise metal parts with smooth surfaces and tight tolerances.
This process is widely known as Die Casting.
🏭 How Pressure Casting Works
- Molten metal (usually aluminum, zinc, or magnesium) is heated in a furnace.
- The molten metal is injected into a steel mold (die) at high pressure.
- The metal fills the mold cavity quickly.
- The metal solidifies under pressure.
- The mold opens and the finished part is ejected.
Injection pressure: 1,500 – 25,000 psi (10 – 170 MPa)
⚙️ Types of Pressure Casting
1️⃣ Hot Chamber Die Casting
- Injection system is submerged in molten metal.
- Faster cycle time.
- Used for:
- Zinc
- Magnesium
- Low melting-point alloys
2️⃣ Cold Chamber Die Casting
- Molten metal is ladled into a chamber before injection.
- Used for:
- Aluminum
- Brass
- Copper alloys
- Slower than hot chamber but handles higher melting temperatures.
🏗️ Materials Commonly Used
- Aluminum alloys
- Zinc alloys
- Magnesium alloys
- Brass
- Copper
✅ Advantages
- Very high production speed
- Excellent surface finish
- High dimensional accuracy
- Thin wall capability
- Good mechanical strength
- Minimal post-processing required
❌ Disadvantages
- High initial mold cost
- Not economical for small production runs
- Limited to non-ferrous metals
- Possible air entrapment (porosity)
