Perforated Chaplets
Perforated Chaplets (also referred to as core stabilizers, box chaplets, pipe chaplets and channel chaplets) are manufactured from tin coated steel sheet or non-ferrous sheet, depending on the metal being cast. These chaplets can be used in thin-walled or heavy metal sections of castings but are best suited for placing in the bottom or drag of the mold. Standard perforation is # 6 or .075 hole on .125 center. Standard material thickness is .030. Perforated chaplets can be produced to resemble a box, Form # 1 and 1A. The information listed below details general characteristics on their dimensional design.
