The Magnesium Die Casting Process
The die casting process for magnesium follows a structured workflow optimized for speed and precision, leveraging magnesium’s unique thermal properties.
- Preparation: The steel die is preheated (180–250°C) and coated with a lubricant to prevent metal sticking and ensure smooth ejection.
- Injection: Molten magnesium alloy is injected into the die cavity at high speed (2–6 m/s) and pressure (40–120 MPa), ensuring full filling of complex geometries.
- Cooling: The metal solidifies rapidly (10–25 seconds) in the die, maintaining dimensional accuracy while pressure is held to reduce porosity.
- Ejection: The die opens, and ejector pins push the finished part out—magnesium’s low shrinkage rate (0.8–1.2%) ensures the part retains its shape.
- Post-Processing: Excess material (flash) is trimmed, and parts undergo optional machining or surface treatment to meet final specs.
- Automation: Robotic arms handle injection, ejection, and post-processing steps, reducing human error and increasing production efficiency by 30%.
On average, the total cycle time for a medium-sized magnesium part (e.g., a laptop frame) ranges from 15–30 seconds.

| AM Series | AM60B, AM50A | Higher ductility than AZ series, good impact resistance | Structural components (aerospace brackets, consumer goods frames) |
| AE Series | AE44 | High heat resistance (up to 150°C), good corrosion resistance | Engine components, high-temperature industrial parts |
| Custom Alloys | Blended to specs | Tailored for enhanced corrosion resistance or strength | Medical devices, marine components |
All our magnesium alloys undergo rigorous testing for corrosion resistance (via salt spray testing) and mechanical properties to ensure consistency.
Surface Treatment for Magnesium Die Cast Components
Surface finishing is essential for magnesium parts, as it enhances corrosion resistance (a key consideration for magnesium) and improves aesthetics.
| Treatment Method | Purpose | Advantages | Ideal For |
| Anodizing | Creates a hard, protective oxide layer | Excellent corrosion resistance, customizable colors (clear, black) | Automotive exterior parts, aerospace components |
| Powder Coating | Applies a durable polymer finish | Chip-resistant, UV-stable, wide color range | Outdoor equipment, consumer goods |
| Plating | Adds a metal layer (e.g., nickel, chrome) | Improves conductivity, decorative appeal | Electrical connectors, medical devices |
| Painting | Enhances aesthetics and basic protection | Fast application, low cost | Non-critical structural parts, consumer goods |
| Coating | Applies a specialized protective layer (e.g., ceramic) | Superior corrosion resistance, heat tolerance | High-temperature parts, marine components |
| Surface Quality Optimization | Polishing, deburring | Smooth finish, removes minor defects | High-end electronics, luxury goods |
