Abstract
A heating mechanism for zipper forming machines includes a mold base, a support seat, a seat cover, a screw sleeve and a heating element. The support seat has a clearance at a central portion and a heat insulation pad is fitted into the clearance for dividing the support seat into a heating area and a cooling area. The heating element is disposed in the heating area and a cooling element is disposed at the cooling area for enhancing heat energy efficiencies and reducing noise.
