KALPUR direct pour technology
KalpurKALPUR for steel direct pour units are an efficient, productive and profitable alternative to conventional runner and gate systems

KALPUR for steel direct pour units eliminate the need for long runners and complicated gating systems while providing clean metal and non-turbulent mold filling. They also reduce the riser size required when compared to sand risers and may eliminate risers necessary to overcome the adverse thermal gradients created by conventional gating.

KALPUR units act as a combination pouring cup, filter, and riser. They let you pour metal directly into the mold and ensure hot metal where you need it, reducing inclusions and improving the foundry’s control of directional solidification.

Innovative KALPUR for steel direct pour units rewrite the rules for gates and risers.

KALFLO for steel  units allow proper selection and placement of steel filters in round neck down riser sleeves, providing foundries un-equaled methoding and operational flexibility.

The use of KALPUR direct pour technology provides the foundryman with the quality advantages of metal filtration, whilst at the same time offering significant cost and productivity improvements including:
• higher yield from the elimination of running systems and hence a reduced metal requirement
• more room on the pattern plate for further castings or reduction in mould box size
• enhanced directional solidification
• less scrap, in-house and at the customer
• reduced fettling and cleaning
• reduce welding and repair
• improved surface finish
• better machinability
