MAXIMUM TECHNOLOGY IN TOOLING VENTILATION

VENTISTAMP VENTILATION TECHNOLOGY
SUPER SELF-CLEANING
The super tapered slots hinder the entrapment of sand
grains inside them, reducing frequency of vents
clogging and of stops for the machine cleaning.
Ventistamp revolutionized the venting concept being the only manufacturer of vents with super tapered slots that
follow the geometry of the tooling cavity.
• No vents adjustments required;
• Reduction of the vents mark on the sand core and on the
sand mold;
• Fast vents exchange in the curved regions of the cavity;
• Better sand compactation.

EXCELLENCE IN DESING
Tests in production proved that the unique slots taper allows to increase in up to 300% the capacity of clogging
resistance, increasing tooling productivity and core sand quality.

Internal slot detail
Ventistamp uses stainless steel and Maganese Brass Alloy that are
considered high permance materails to manufacture their vents,
what provides greater resistance to the sand abrasive affect and
increases the vents lifespan.
