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).

Abstract: A mold split insert for use in a molding stack assembly, and in particular a preform mold neck ring insert for use in an injection molding stack assembly for making bottle mold preforms. The split insert comprises a body with a molding surface configured thereon. The split insert also includes a coolant channel configured in the body with a partition arranged therein. The partition dividing a portion of the coolant channel into a first and a second branch. A transfer coolant channel is configured between the branches.

Abstract: A device for temperature adjustment of an object generally comprises means for providing a flow of a conditioning fluid, said flow of conditioning fluid being directed along a surface of said object, and at least one fin directed towards said surface of said object. The at least one fin is arranged in the immediate vicinity of said surface of said object so that an edge of said fin extends substantially normally with respect to said flow of said conditioning fluid, said conditioning fluid passing between said surface of said object and said edge of said fin.

Abstract: A device for temperature adjustment of an object generally comprises means for providing a flow of a conditioning fluid, said flow of conditioning fluid being directed along a surface of said object, and at least one inner wall directed towards said surface of said object. The at least one inner wall is arranged in the immediate vicinity of said surface of said object so that an edge of said inner wall extends substantially normally with respect to said flow of said conditioning fluid, said conditioning fluid passing between said surface of said object and said edge of said inner wall.
