MeltVents-KT increases the productivity of permanent mold like no other type of vent, because they have exclusive super tapered slots (Required Patent) that reduce aluminum clogging.





Tests done in gravity casting, using 5 vents with Ř 10mm, demonstrated the great efficiency of the super tapered slots in relation to the aluminum clogging.

THAT THE ALUMINUM TOUCHES MELTVENTS-KT.



Moment when the aluminum touches MeltVents-KT, during the mold filling, causing a slight penetration in the slots with INVERTED taper.

Ventistamp achieved excellent results producing the MeltVents-KT pattern in Bronze-Aluminum Alloy. It is a high performance alloy because it has:

• Great resistance to high temperature, for this reason, it is also used in the manufacturing of injection pistons of the aluminum injectors.

• A higher thermal conductivity when compared to Stainless Steel Alloys (approximately 250% higher). This feature allows the vent to accelerate the aluminum cooling process, what reduces the aluminum fluidity and avoids its penetration into the slots..



MeltVents-KT patterns can be manufactured in a way that their slots follow the cavity geometry. It is a unique advantage that allows increasing the casting parts quality, even in the most complex areas in the mold.





• MAXIMUM CLOGGING RESISTANCE

• BETTER QUALITY OF THE CASTING PART
• LONGER LIFE SPAN

• GREATER PRODUCTIVITY OF PERMANENT MOLD
