Are Magnesium Alloy Particles Suitable for High-Volume Thixomolding?

Engineering Assessment

For high-volume Thixomolding, particle consistency can significantly influence process stability and component quality. Billet-cut magnesium alloy particles are generally preferred where tighter control of particle size, surface condition, and melting behavior is required.

Typical Engineering Considerations

• Particle size tolerance: ≤ ±0.2 mm

• Near-spherical geometry for stable feeding

• Low surface oxide content

• Chemical composition compliant with ASTM B93

Potential Process Risks

• Wide particle size variation may result in non-uniform melting and inconsistent mold filling.

• Surface oxide inclusions may increase the risk of internal defects and reduced fatigue performance.

• Semi-solid processing without adequate inert gas protection may increase oxidation and handling risks.

Typical Applications

• High-volume Thixomolding

• Thin-wall 3C electronic housings

• Lightweight automotive structural components

Engineering Note

Feedstock selection should be based on component geometry, process capability, quality requirements, and production volume. Material suitability is typically verified through process trials and production validation rather than material specifications alone.

Real-world Mistakes 

Common Pitfall: Using crushed chips or irregular granules to reduce procurement costs.

The Cost: Irregular morphology causes screw jams and feeding inconsistencies, dropping qualified yield below 60%.

Engineering Action: Enforce Billet-Cut Precision Particles (±0.2mm tolerance) to maximize OEE and process stability.

Supply Integrity 

Aikerly does not just deliver material; we deliver Equipment OEE (Overall Equipment Effectiveness):

• Core Process: Proprietary cutting lines utilize physical shearing instead of thermal melting, preserving the material's original mechanical properties.

• Specifications: Full range of 3–8 mm particles covering AZ91D, AM60B, and ZK61M alloys.

• Capacity: Modular production supports stable output of 300–700 kg/h, ensuring a 7–25 day rapid response for volume orders.

• Quality Audit: Every batch is issued with a PSD (Particle Size Distribution) curve, purity analysis, and SEM morphology report.fully compliant with ASTM B93/B93M
