Our insulating hot tops utilize materials with low thermal conductivity. This creates a barrier that slows heat loss from the riser, extending molten metal time for optimal feeding of the casting and reduced waste.

Our exothermic hot tops feature a highly reactive composition that generates intense heat. This delays solidification in risers, promoting directional feeding and minimizing shrinkage defects in castings for improved yield.

Anti-piping compounds are used in the foundry industry to prevent the formation of pipes or shrinkage cavities in castings. These compounds are applied to the top of the molten metal in the mold just before pouring. They act as a barrier, preventing the molten metal from contacting the atmosphere and thus reducing the risk of shrinkage defects. Antipiping compounds typically consist of a mixture of materials such as clay, graphite, and other refractory materials.

The sealing compound with a hot top is used to seal the junction between the hot top and the mold, preventing molten metal from leaking out during the casting process. This type of sealing compound is designed to withstand high temperatures and provide a tight seal to prevent any loss of molten metal.
