Feeding Systems for Sound Castings in Steel Foundries

Foseco’s feeding system products are designed to help foundry operators make sound castings for less money. Foseco is the global leader in feeding system products because our products have the highest thermal and feed performance available. And, because Foseco’s feeding aids are carefully made in very reliable processes, feed performance is particularly consistent.

The application of Foseco feeding solutions avoid shrinkage defects and improve casting yields, reducing the amount of non-productive metal poured. Significant savings can also be made in fettling and cleaning operations.

KALPUR Direct Pour Technology

The KALPUR direct pouring process is the combined use of a feeder sleeve and ceramic foam filter. It is suitable for hand-moulded castings, and horizontal and vertical automatic moulding lines. The KALPUR process entirely eliminates the need for a conventional running system.

KALMINEX Exothermic-insulating Feeder Sleeves

KALMINEX is an exothermic-insulating range of feeder sleeves supplied as preformed cylinders, ovals and neck-downs in a range of diameters up to 850 mm. They are ideally suited for jobbing steel applications.
KALMINEX BSA are accurately formed, highly exothermic and insulating shapes suitable for feeding all grades of cast steel. They are available as open or blind sleeves in the diameter range of 30 – 150 mm.

KALBORD Prefabricated, Flexible Boards

KALBORD flexible insulating boards are ideal for use as insulating feeders for very large steel castings, especially for feeders with a diameter >500 mm.

FERRUX Anti-piping Compounds

FERRUX is a range of exothermic insulating anti-piping compounds for covering steel risers. FERRUX improves feeder performance and minimises skull formation.

KAPEX Insulating and Exothermic Preformed Lids

KAPEX is a range of preformed lids suitable for application to KALMIN and KALMINEX open feeders. On application, an exothermic reaction causes KAPEX to expand by as much as 200%, producing a highly insulating cover layer.

SCK - Sleeve Construction Kit

The SCK system is a modular system for jobbing castings, allowing the foundry to tailor the sleeve package to the appropriate modulus to maximise yield and minimise the riser footprint.

The SCK set can be assembled to achieve the required modulus with smallest contact area. The system is therefore an ideal solution for casting sections which offer minimum footprints. 

Excellent feeding efficiency will ensure a clean casting surface at the contact sleeve area. The highly exothermic components will be placed on the lower insulating parts via an interlock system. Locator pins are used for centering the set
