Aluminum Gravity Die Casting Allowing Heat Treatment to Enhance Mechanical Properties, High Durability Gravity Die Casting

Product Description

 

Product Description

 
Gravity Die Casting (GDC), also known as permanent mold casting, is a liquid metal forming process where molten metal is poured into a reusable metal mold (typically made of steel or cast iron) solely under the force of gravity, then solidified and ejected to form the desired part.

Mold & Driving Force: Reusable permanent molds enable high repeatability; filling relies entirely on gravity, no high-pressure injection.
Suitable Materials: Mainly non-ferrous alloys such as aluminum alloys, as well as zinc, magnesium, copper, and brass.
Process Flow: Melting → Mold preheating → Pouring → Cooling & solidification → Mold opening & ejection → Post-processing (machining, surface treatment) → Inspection.
 

Advantages & Application

 

Advantages 
Higher dimensional accuracy and surface quality than sand casting; dense structure with low porosity, allowing heat treatment to enhance mechanical properties; cost-effective for medium-to-high volume production.

Application
Ideal for structural parts with medium complexity and wall thickness, widely used in automotive (engine blocks, gearbox housings), machinery (pumps, valves, connectors), consumer electronics, and sports equipment.
