Abstract
Embodiments of the present invention are directed to a tonnage regulating structure and a mold incorporating same. For example, a tonnage regulating structure (302, 1002, 1202) for use in a mold (502) of a molding machine, the mold (502) being associated with an opening clearance (520) between mold faces in a mold closed and clamped configuration, is provided. The tonnage regulating structure (302) comprises a body (304, 1040, 1240) having a first height (306) in a resting configuration, the first height (306) selected to be larger than the opening clearance (520) between the mold faces in a mold closed and clamped configuration; the body (304, 1040, 1240) including a compensating structure (308), the compensating structure (308) for regulating, in use under applied clamp tonnage, the body (304, 1040, 1240) to a second height (320), the second height (320) being smaller than the first height (306).
