Abstract: Disclosed herein, amongst other things is a component (100, 200, 300, 400, 500, 600, 700, 800, 900, 1000) of a molding system (402) (e.g. mold component, post-mold component, etc.) having a heat dissipater (130, 230, 330, 430, 530, 630, 730, 830, 930, 1030) that is configured to impart a profiled heat removal rate on a selected portion of a molded article (120, 220, 320, 420) that generally matches a heat distribution therein.

Abstract: There is provided a mold stack (100). The mold stack comprises a cavity insert (110) configured to define a portion of a molding cavity (108) for defining a body portion of a preform to be molded therein, the cavity insert (110) positionable, in use, within a bore (113) in a cavity plate (114) in a loose fit arrangement, allowing for a degree of float, in a lateral direction, of the cavity insert (110) relative to the cavity plate (114).

Abstract: A method is provided of cleaning of a portion of a mold component, the portion of the mold component including a passage configured, in use, to allow passage of fluid and to prevent passage of melt, the method comprising: entering the mold component into a cleaning configuration, whereby a portion of the passage becomes part of a molding surface; performing a molding cycle to fill in at least the portion of the passage with molding material for incorporation and removal of a residue there from. Also provided is a mold having a first mold half and a second mold half, the halves being movable relative to each other. A mold shut height adjustment apparatus can provide for a change in the mold shut height.

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).
