Product Overview

Aluminum Gravity Die Casting (also known as permanent mold casting) is a sophisticated metal forming process where molten Aluminum is poured into reusable metal molds under the force of gravity rather than under high pressure as in traditional die casting. This process yields components with exceptional dimensional accuracy, superior surface finish, and excellent mechanical properties. Our tilting-type gravity casting machines allow for controlled metal flow, resulting in castings with minimal porosity and superior structural integrity.

Our Aluminum gravity die cast parts are engineered to meet the exacting standards of various industrial applications. With wall thicknesses ranging from 3mm to 25mm and weights from 50g to 20kg, our capabilities encompass a wide spectrum of component sizes and complexities. The permanent mold casting process enables the production of complex geometries with internal passages, precise threading, and integrated mounting features that would be challenging or impossible to achieve with other manufacturing methods. Each component undergoes rigorous inspection and testing to ensure consistent quality and performance across production batches.

Material Properties

Manufacturing Process

Our Aluminum gravity die casting production follows a meticulously controlled process:

1. Design & Engineering: Collaborative development with clients to optimize component design for gravity die casting, including gating system design and solidification simulation using advanced CAD/CAM software and casting simulation tools.
2. Pattern & Die Manufacturing: Precision CNC machining of permanent metal molds (typically H13 or H11 tool steel) with carefully engineered cooling channels, venting systems, and draft angles to ensure optimal casting quality.
3. Material Selection & Preparation: Raw material is inspected and tested for chemical composition and purity before being charged into the melting furnace.
4. Melting & Metal Treatment: Aluminum is melted in electric or gas-fired furnaces under controlled conditions. The melt undergoes degassing, grain refinement, and modification treatments to enhance final casting properties.
5. Die Preparation: The permanent mold is preheated to optimal temperature (typically 150-300°C) and coated with specialized refractory die coatings to facilitate easy release and improve surface finish.
6. Casting Process: Using our tilting-type gravity casting machines, molten Aluminum is poured into the die cavity at controlled rates to minimize turbulence and entrapped gases. The tilting mechanism ensures smooth, laminar flow of metal.
7. Solidification & Cooling: The filled die is allowed to cool for a predetermined time under controlled conditions, often with strategic cooling channels to optimize solidification patterns and minimize shrinkage.
8. Ejection & Initial Inspection: Once solidified, the casting is ejected from the mold and undergoes preliminary visual inspection for surface defects.
9. Post-Casting Operations: Depending on specifications, castings may undergo:
   • Trimming and gate removal
   • Heat treatment for enhanced mechanical properties
   • Precision machining of critical surfaces
   • Surface finishing processes (shot blasting, polishing, painting, anodizing)
10. Quality Control: Comprehensive inspection using coordinate measuring machines (CMMs), X-ray analysis, dye penetrant testing, and mechanical property testing ensures compliance with specifications.

Frequently Asked Questions

Q: What is the difference between gravity die casting and high-pressure die casting?
A: Gravity die casting relies on gravity to fill the mold rather than high pressure. This results in castings with lower porosity, better mechanical properties, and the ability to be heat treated. It’s ideal for components requiring pressure tightness, higher strength, and the ability to be welded.

Q: What wall thickness can be achieved with your gravity die casting process?
A: Our standard gravity die casting process can achieve wall thicknesses ranging from 3mm to 25mm, compared to high-pressure die casting which typically handles thinner walls (0.5-3mm). The thicker walls possible with gravity die casting often result in more robust components with better structural integrity for certain applications.

Q: Can Aluminum gravity die cast parts be heat-treated?
A: Yes, unlike high-pressure die cast parts which often contain entrapped gases that cause blistering during heat treatment, gravity die cast components can undergo various heat treatments including T6 strengthening treatments. This allows for significant enhancement of mechanical properties such as tensile strength and hardness.
