Gravity permanent mould casting
In gravity casting, the molten metal fills the mould mainly by its own weight. The process is suitable for aluminium and brass parts requiring reproducible series quality and good surface finish.
Gravity Casting Machines
Gravity die casting machines are used for casting in reusable metallic permanent moulds. They are particularly suitable for medium to large series where dimensional accuracy, surface quality and stable mould temperature control are essential.
FISS Machines offers used gravity die casting machines, permanent mould casting machines and tilt casting machines for aluminium and brass alloys. Depending on the system, melting and holding furnaces, casting robots, metal dosing systems, casting extraction, portal handling and cooling technology may already be part of the machine solution.
Permanent mould casting
Casting in a metallic mould
In gravity die casting, the molten metal is poured into a metallic permanent mould. Unlike sand casting, the mould remains in use and can be used for many casting cycles. This enables short cycle times, reproducible part quality and good surface finish.
The mould must not only match the component mechanically. Preheating, mould coating, cooling, extraction and consistent temperature control during series production are also decisive.
Preparation
Prepare the mould
Clean, coat, temper and close the mould for the next casting cycle.
Molten metal
Feed the molten metal
Provide aluminium or brass alloy from a furnace, ladle or dosing system.
Mould filling
Fill the mould in a controlled way
Gravity, tilting movement or casting robot control the filling process.
Extraction
Solidify and extract
Thermal balance, ejectors and handling determine quality and cycle time.
Gravity casting, tilt casting and automated gravity die casting systems
Gravity die casting machines can be configured differently depending on the component, alloy and production volume. The key factors are how the molten metal enters the permanent mould, whether the mould is moved and how extraction, cooling and peripheral equipment are integrated into the process.
Tilt casting machines
In tilt casting, the mould is moved during the filling process. This can make the mould filling calmer and more controlled, especially for more demanding component geometries.
Automated systems
In automated gravity die casting systems, casting robots, metal dosing systems, extraction units, portal handling, furnaces and cooling technology work together as a coordinated system.
Thermal balance, mould and casting quality
The thermal balance of the mould influences solidification, surface quality, dimensional accuracy and cycle time. Preheating, mould coating, targeted cooling and stable temperature control must match the component and alloy.
For used gravity die casting machines, it is therefore important to assess not only the machine itself, but also the mould condition, slides, core pulls, cooling circuits, ejectors, furnace technology and existing automation.
What to check when buying a used gravity die casting machine
When buying a used gravity die casting machine, it should be checked whether the machine, mould, furnace technology, casting system, component size, automation and existing peripherals match the planned production process.
