KALMIN 70 riser sleeves are highly efficient insulating riser sleeves

KALMIN 70 riser sleeves are insulating, lightweight riser sleeves used to efficiently feed steel castings. They are highly heat resistant and provide superior insulating characteristics. The use of riser sleeves increases casting yield by allowing smaller riser sizes than conventional sand risers and reduces cleaning costs.

KALMIN 70 Round Neckdown Sleeves further reduce the riser casting contact size, minimizing the need for breaker cores. Also, risers can be located on a smaller area which can reduce or eliminate metal padding.  

KALMIN 1000 sleeves

KALMIN 1000 riser sleeves are highly efficient insulating feeders designed for carbon, alloyed steel and alloyed iron casting applications.

KALMIN 1000 riser sleeves feature a unique refractory system that is able to withstand high temperature and metal pressure over extended solidification times typically associated with large diameter risers. In addition, the novel KALMIN 1000 formulation is very low in nitrogen bearing materials and sources of metallurgical tramp elements; thereby maintaining the chemical integrity of riser feed metal for the casting. Optimized riser sleeve wall thickness and an advanced binder system make KALMIN 1000 sleeves very robust in green sand molding operations.

These features combine to deliver consistently high levels of feed performance, easy riser removal and reduced tendencies for under riser cracking over a broad range of casting applications.

KALMINEX 21 riser sleeves

KALMINEX 21 riser sleeves are highly efficient exothermic-insulating feeders designed for carbon, alloyed steel and alloyed iron casting applications.

KALMINEX 21 riser sleeves feature a unique refractory system that is able to withstand high temperature and metal pressure over extended solidification times typically associated with large diameter risers. In addition, the novel KALMINEX 21 formulation is low in nitrogen bearing materials and sources of metallurgical tramp elements; thereby, maintaining the chemical integrity of riser feed metal for the casting. Optimized riser sleeve wall thickness and an advanced binder system make KALMINEX 21 very robust in green sand molding operations.

These features combine to deliver consistently high levels of feed performance, easy riser removal and reduced tendencies for under riser cracking over a broad range of casting applications.

KALMINEX 21 sleeves are available in tube and round neckdown form.

Round Neckdown Sleeves further reduce the riser casting contact size, minimizing the need for breaker cores. Also, risers can be located on a smaller area which can reduce or eliminate metal padding.

KALMINEX 2000 riser sleeves

KALMINEX 2000 riser sleeves are highly efficient, exothermic-insulating riser sleeves used to effectively feed steel castings. The use of riser sleeves increases casting yield by allowing smaller riser sizes than conventional sand risers and reduces cleaning costs.  

KALMINEX 2000 riser sleeves are available in tube, round neckdown and insert form (see below.)

Round Neckdown riser sleeves further reduce the riser casting contact size, minimizing the need for breaker cores. Also, risers can be located on a smaller area which can reduce or eliminate metal padding.

KALMINEX 2000 round neckdown riser sleeves are also available with sand breaker cores for an even smaller and more precise contact area.

KALMINEX 2000 insert sleeves

KALMINEX 2000 insert riser sleeves are highly efficient riser sleeves designed with closely controlled external dimensions that permit insertion into the mold cavity after the mold is produced. These riser sleeves are provided in an exothermic-insulating formulation designed for optimum feeding efficiency when used in steel casting applications.
