Gravity Die Casting (Conventional Process)
High Porosity
Using GISS Semi-Solid Casting Technology
Low PorosityGISS Technology creates semi-solid slurry by injecting inert gas into molten aluminum, forming fine globular solid particles that improve flow and reduce defects.
Lower porosity and more consistent casting quality.
Shorter cycle time, less energy and longer die life.
Enable wrought aluminum alloys such as 6061, 6063 and 7075 for new applications.
Porosity, cycle time and die wear quietly drain margin from every production day.
Entrapped gas causes defects, leakage and inconsistent quality.
Poor feeding and solidification create internal cavities.
High heat content slows production and reduces output.
Thermal load shortens die life and increases maintenance cost.
Excessive heat, lubricant and water treatment increase cost.
GISS Technology controls the metal condition before casting, turning common production losses into measurable process improvements.
Fine globular solid particles reduce gas entrapment and shrinkage defects before they become scrap.
Semi-solid slurry carries less heat into the die, reducing thermal load and improving stability.
Faster solidification helps increase output while keeping process conditions more consistent.
Lower temperature stress reduces die wear, maintenance pressure and unplanned downtime.
This is where GISS Process should be explained: after proven results and before business benefits, so readers understand why the results happen.
By injecting micro-sized inert gas bubbles into the liquid metal, GISS Technology converts it into superheated slurry, which effectively fills die cavities with lower heat content. This results in cost benefits like extended die life and reduced cycle time. The controllable solid fraction in the slurry allows precise flow control, reducing gas porosity and shrinkage porosity due to pre-existing solid particles.
GISSCO integrates GISS Units into existing production setups, using current die casting machines and dies, and provides full technical support, optimizing die casting parameters without needing modifications to existing die designs.
GISS probe measures and controls the melt condition.
Inert gas is injected into molten aluminum.
Micro gas bubbles mix with the melt to create slurry.
Fine globular particles improve flow and casting quality.
GISS Technology is designed for practical industrial deployment across machine sizes, part weights, casting processes and alloy families.
In the GISS high-pressure die casting process, the high-pressure die casting machine and process cycle remain largely unchanged from conventional high-pressure die casting. The only added step occurs during the ladle transfer when a diamond probe is immersed. Therefore, no significant modifications are needed for existing high-pressure die casting equipment.
Adding the GISS process to create semi-solid slurry before squeeze casting is very simple. This process results in high density, near-zero porosity, heat-treatable, and high mechanical properties.
GISS slurry casting under gravity pressure produces finer, more uniform grain structures with less shrinkage porosity. This process shortens solidification time by 40%, resulting in significant cycle time savings, improved mechanical properties, and better casting yield.
GISS Technology can process pure aluminum, copper, silver, gold, and other metals, as well as a wide range of commercial alloys including aluminum, magnesium, zinc, copper, lead, tin, and iron. In fact, all metals and alloys can be effectively processed with GISS Technology.
