Tie every gravity cast part to its alloy melt, die coat and pour record.

A gravity die casting shop fills a steel die with molten metal using only gravity, often by tilting the die so the metal runs in gently. Sand or shell cores form the hollow shapes. The method suits thicker walls, pressure parts and medium runs, such as cylinder heads, pump housings, wheels and fittings, where a steady fill matters more than speed. Quality depends on melt cleanliness, die temperature and a steady pour. Small drifts show up as porosity. Scrap follows. It is costly.

Software for gravity die casters keeps the alloy melt, the die and the pour with each casting batch. Planners see each die and machine as a queue with its preheat and coat state, and furnace staff see which melt is ready to feed the next die. Quality staff see which test result belongs to which batch. The shift handover reads from one record, so the next crew starts with the melt, die and coat state already written down.

A customer orders castings against a drawing and an alloy specification, such as a pump housing in an aluminium silicon alloy with a heat treatment called for. The planner books the die on a casting machine. Stores issues ingot, and the furnace crew melts, treats and degasses the metal. A spectrometer sample confirms the alloy before pouring begins. Then the die is made ready.

The die is preheated and sprayed with a coat. Cores are set by hand, the die is closed, and the pourer fills the ladle and tilts or pours. Parts are shaken out. Gates and risers are cut off, and the castings are fettled. Heat treatment follows for many parts, and then come pressure testing, X-ray on a sample, dimensional checks and machining, each of which leaves a record that someone must file. The delivery note carries the batch, melt number and the test results. The customer can check them.
