Freeman's Guide To Core Vents
Go directly to Part 2: Freeman's Line of Core Vents
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...
Three basic metals are offered: Brass, Steel, and Aluminum.
#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.
#3 - Slot Width/Screen Mesh:
The width of the slot or the size of the mesh required is determined by the size of the sand (mesh) being used in the construction of your core. The width/mesh of your vent must not be greater then the sand mesh in order to hold the sand in the core box while permitting the air to escape.
