The catalogue
Every grade below is manufactured in-house, released through our molten-metal laboratory, and run daily on the group's own moulding lines before it runs on yours.
Green sand · additive
The surface finish of a green sand casting is made at the metal–sand interface. MAGNAKOL's high thermal stability generates lustrous carbon with minimum burnout across the full depth of the mould — so the mould peels cleanly off the casting, at lower addition levels than conventional additives.

Green sand · engineered blend
No two sand systems behave alike. MAGNACARB is blended to your system — coal dust pre-mixed with sodium bentonite in ratios tuned to your green sand properties — so compactability, green strength and gas evolution stay inside the window your line was set up for.

Risering · exothermic
MAGNEX sleeves ignite on contact with molten metal and burn above 1500 °C, holding the riser liquid roughly 2.5× longer than a sand riser. The casting feeds fully, shrinkage porosity moves into the riser, and yield per mould rises — with no carburization or contamination of the melt.
Specifications
Risering · insulating
Accurately formed, low-density insulating sleeves for insert or ram-up application in iron, steel and non-ferrous castings. Where an exothermic reaction would risk contamination — stainless and non-ferrous work especially — MAGNIN extends solidification 2–2.5× purely by insulation, chemically inert and clean.
High-density sleeve variants are also produced for applications needing extra mechanical strength — ask our team.
Specifications
Pouring · feeding + filtration
MAGPOUR combines an insulating riser body with a ceramic foam filter in one piece — you pour directly into the riser. Slag and inclusions stop at the filter, the riser does the feeding, and the entire gating system's worth of non-productive metal is simply never poured.

Melt treatment · inoculants
Traditionally, foundries juggled separate inoculating agents — ferrosilicon, graphite, calcium, barium, rare earths. MAGNASEED balances them in one formulation per grade, seeding the melt with uniform nucleation sites for chill reduction, better machinability and mechanical properties that repeat, ladle after ladle.
