Ultra-Lightweight Magnesium Die Casting Solutions
Magnesium is the lightest of all structural metals, offering a strength-to-weight ratio that rivals sophisticated composites while maintaining the durability and EMI shielding properties of metal. For industries obsessed with weight reduction—such as electric vehicles, handheld electronics, and aerospace drones—Magnesium Die Casting is the ultimate manufacturing solution.
At JUCHENG, we have mastered the complex process of casting this highly reactive metal. Our facility is equipped with specialized hot-chamber and cold-chamber machines featuring inert gas shielding to ensure safe, porosity-free casting. We help you push the boundaries of design by producing thin-walled, intricate magnesium components that significantly reduce your product's overall weight without sacrificing rigidity.

Magnesium Die Casting
JUCHENG’s Magnesium Manufacturing Expertise
Processing magnesium requires strict environmental control and specialized finishing. We offer:
- Thin-Wall Casting: Taking advantage of magnesium's low viscosity, we can cast walls as thin as 0.8mm - 1.0mm, which is significantly thinner than what is possible with aluminum.
- Safety & Process Control: Our casting cells are equipped with advanced SF6/N2 protection gas systems to prevent oxidation and ensure safe melting.
- Corrosion Protection: Magnesium corrodes easily. We provide essential in-house surface treatments including Chemical Conversion Coating, Anodizing (Type II), and E-Coating to seal the surface immediately after machining.
- Mecanizado de precisión: Because magnesium machines faster than any other metal, we can rapidly drill, tap, and face sealing surfaces with minimal tool wear.

Magnesium Alloy Selection
We cast the most reliable high-purity magnesium alloys:
| Alloy Grade | Characteristics | Best Application |
| AZ91D | The most commonly used alloy. Excellent castability, high strength, and moderate corrosion resistance. | General electronics, power tools, brackets, computer parts. |
| AM60B | Features higher ductility and elongation (toughness) than AZ91D. Better energy absorption. | Automotive steering wheels, seat structures, safety components. |
| AM50A | Even higher ductility than AM60B. Reduces tendency to crack under stress. | Interior automotive panels, thin-walled structural die castings. |
| AS41B | Superior creep resistance at higher temperatures (up to 150°C). | Engine components, transmission cases (where heat is a factor). |
Comparison
Why choose Magnesium over cheaper alternatives?
| Feature | Magnesium Die Casting | Aluminum Die Casting | Injection Molded Plastic |
| Weight | Lightest (1.8 g/cm³) | Medium (2.7 g/cm³) | Light (1.0-1.4 g/cm³) |
| Stiffness | High | High | Low (Flexible) |
| Shielding | Excellent EMI/RFI | Excellent EMI/RFI | None (Unless coated) |
| Wall Thickness | Thinnest (0.8mm) | Thin (2.0mm) | Variable |
| Heat Dissipation | Good | Best | Poor (Insulator) |
| Damping | Excellent (Absorbs vibe) | Low (Rings) | Good |

The JUCHENG Magnesium Advantage
- Fire Safety Protocols: Magnesium dust is flammable. Our facility is built with wet-type dust collectors and strict safety protocols, ensuring stable production without interruption.
- Surface Finishing Mastery: Painting magnesium is tricky. Our dedicated paint line uses specialized primers to ensure 100% adhesion and salt-spray resistance.
- Tooling Longevity: Magnesium is less abrasive to steel than aluminum. We optimize mold designs to achieve tool lives exceeding 200,000 shots, reducing your long-term capex.
- Integrated Assembly: We install thread inserts (Helicoils) to provide durable steel threads in the soft magnesium body for repeated assembly.
Advantages
Key Benefits of Magnesium Casting
- Lightest Structural Metal: 33% lighter than aluminum and 75% lighter than steel.
- EMI/RFI Shielding: Protects sensitive electronics from interference without needing conductive paint (unlike plastic).
- Vibration Dampening: Absorbs energy and vibration better than aluminum, improving the lifespan of mounted electronics or optics.
- Eco-Friendly: Magnesium is abundant and 100% recyclable.
