Air Vent corevent

Core box air release vents enable "core blowing" equipment to effectively fill the core box with sand, and allow for the safe escape of gases, heat, and air during core manufacturing. Freeman offers a large selection of vents in brass, brass alloy, steel, and aluminum for a wide range of applications.

When selecting the proper core vent for an application, please follow these guidelines...

#1 - Type of Metal:

Three basic metals are offered: Brass, Steel, and Aluminum. Brassis a softer metal which makes it easier to contour, remove from the core box, and clean. Brass Alloy(SAE-430-B), available only with Ventistamp core vents, features higher wear resistance than steel. Steelvents offer greater wear resistance, can withstand higher temperatures, and match metal with steel core boxes for uniform heating and cooling. Aluminumvents are popular for Styrofoam molding applications and offer many of the same advantages as the steel vents. #2 - Style of Vent:

Nearly all of the core vents sold are one of the four styles: Shalco Super Vents, Ventistamp Zanatta vents, Slotted vents, and Screen vents.
