Along with the moulds, the pouring system is the key to good performance of a casting system. Get the pouring right, and many downstream problems can be avoided.

Ingotech manufacture various pouring mechanisms, and select the most appropriate system for each application:

Aluminium ingot

A rotating cast iron star-wheel is directly driven by the passing moulds, ensuring synchronised pouring. By pouring through two outlets (one each side of the wheel) into the same mould the rate of metal flow in each outlet is halved. This minimises turbulence and dross, allowing top quality ingot to be produced at higher production rates.

We have developed a range of star-wheels to suit different ingot sizes, along with a range of launder sections specifically designed to deliver metal into our star-wheels with minimal turbulence.

Molten metal filtration and flow control can also be incorporated into the machine construction.

Aluminium deoxidant shapes

A pouring tray mounted across the conveyor is rocked in time with the passing moulds by a cam on the output of a heavy duty gearbox of our own design. This is driven from the conveyor tail-shaft. A former is provided to create a uniform shape within the refractory lining of the tray to minimise turbulence, allowing faster casting of metal.

Zinc and lead ingot

Star-wheel systems, principally the same as for Aluminium Ingots are used. Alternatively, a multi-spout pouring bowl is mounted on the side of the casting machine. It is driven by a heavy duty gearbox, of our manufacture, and pours ingots individually as the moulds pass.

Copper and brass ingot

A single spout, refractory lined bowl is mounted on the side of the machine and driven by the heavy duty gearbox. Separate drives for tracking the passing moulds and tilting the bowl ensure cut-off of metal flow between ingots.
