Product Description

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 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.
