Semi-Solid Magnesium Alloy Component Processing

1. Innovation in technical principles
Thixomolding®: Magnesium alloy particles are injected into the mold at high speed in a state of solid (50-60%) and liquid coexistence. The molding temperature is 30% lower than that of traditional die casting, and the grain size is refined to 15μm (50% better than die casting), eliminating pores and thermal cracking defects.

2. Core process advantages
(1) Ultra-high material utilization: Near-net molding technology reduces machining volume, raw material utilization rate reaches 95% (die casting process is only 70%), and unit cost is reduced by 25%.
(2) Extreme lightweight performance: yield strength ≥ 220MPa, elongation > 10%, specific strength 1.8 times that of aluminum alloy, achieving 40% weight reduction of parts.
(3) Micron-level precision control: Tolerance maintained at ±0.05mm (ISO 2768-m standard), surface roughness Ra≤0.8μm, and can be directly PVD coated.

3. Production efficiency breakthrough
(1) Energy-saving manufacturing model: energy consumption is only 40% of the die-casting process (measured ≤1.2kWh/kg), fully enclosed SF6-free protective gas production line, and carbon footprint is reduced by 60%.
(2) High-speed mass production capability: 90-second ultra-short cycle time (including T5 heat treatment), supporting 24/7 continuous production, and annual production capacity of 5 million pieces (single line).

4. Global compliance guarantee
(1) Material safety certification: in compliance with EU REACH Annex XVII cadmium content <0.01%, US ASTM B94-17 standard, and providing IMDS material data sheet.
(2) Process quality control: online X-ray real-time monitoring (generate 3D porosity map for each piece), CPK value stable ≥1.67.

5. Typical application scenarios
(1) Automobile lightweighting: gearbox housing (weight reduction of 3.2kg/piece), steering wheel frame (collision energy absorption increased by 30%)
(2) Consumer electronics: ultra-thin notebook shell (0.6mm wall thickness), drone body (vibration resistance increased by 45%)
(3) Medical devices: MRI equipment bracket (zero magnetic interference), surgical robot joint (2 million times fatigue life)

6. Customized cooperation model
Joint development support: Provide full-process collaboration from material formulation (AZ91D/AM60B customization), mold design (Flow-3D® simulation) to mass production introduction.
