Magnesium Die Casting: Processes and Characteristics

Preheating

Magnesium ingots are first heated to approximately 150°C. This step is essential because only dry ingots can be added to the melting and holding furnaces to ensure safety.

Key Process Steps

• Melting: The ingots are then fed into the furnace for melting.

• Oxidation Prevention: Inert gases are used to cover the melt to prevent oxidation on the surface of the molten pool.

• Temperature Control: The molten magnesium is maintained at a specific temperature until it is poured into the shot chamber.

Introduction to Magnesium Die Casting Advantages

Features and Advantages of Magnesium Die Casting

Core Advantages

• Superior Fluidity: Compared to aluminum die casting, magnesium's excellent fluidity allows for the casting of components with thinner walls and higher complexity.

• Conductivity and Shielding: The metal’s high thermal conductivity and excellent electromagnetic interference (EMI) shielding make magnesium die casting ideal for the electrical engineering industry.

• High Strength-to-Weight Ratio: Compared to plastics, magnesium offers higher strength and significantly better thermal conductivity.

• Abundant Resources: Magnesium is considered an inexhaustible resource.

• Sustainability: Materials recovered within the die casting plant are fully recyclable.

• Corrosion Resistance: High-purity magnesium alloys exhibit excellent corrosion resistance.

• Acoustic Insulation & Lightweight: Magnesium provides good sound insulation properties and is approximately 30% lighter than aluminum.

Characteristics:

Scratches on the casting surface caused by impact.

Causes:

• Accidental damage during gate removal, cleaning, straightening, and handling.

Remedial Measures:

• Handle castings carefully; avoid stacking or impact during storage and transportation; use dedicated storage and transportation boxes.
