What is Gravity Die Casting?
Gravity Die Casting, also known as permanent mold casting, is a sophisticated manufacturing process where molten metal flows into a permanent mold cavity by its own gravity, solidifies upon cooling, and forms the desired casting.
Core Principles and Features
- Simple mold structure with open or semi-open runner designs
- Slow filling speed ensuring stable molten metal flow
- Reduced internal defects such as pores and shrinkage cavities
- Moderate casting density with excellent mechanical properties
Material Compatibility
Leesh’s gravity die casting capabilities cover a wide range of materials:
- Aluminum alloys: ZL104, A356, A360, A413
- Magnesium alloys: AZ91D, AM60B
- Copper alloys
- Cast iron
The T6 Heat Treatment Advantage
Leesh’s T6 heat treatment process transforms standard cast components into high-performance engineering parts through a sophisticated three-stage thermal processing.
Advanced T6 Treatment Process
- Solution Heat Treatment: Precise heating to 530-540°C for aluminum alloys to dissolve alloying elements
- Rapid Quenching: Controlled cooling to retain the homogeneous solution structure
- Artificial Aging: Carefully controlled heating at 120-180°C to precipitate fine strengthening phases
Performance Enhancements
- 30-50% improvement in tensile strength
- Up to 60% increase in yield strength with excellent ductility
- Hardness enhancement from 60-70 HB to 90-110 HB
- Superior corrosion resistance exceeding 96-hour salt spray test
- Exceptional fatigue life and impact resistance
- Outstanding dimensional stability with minimal distortion
