What is claimed is: 1. A cavity insert for a mold stack of a molding machine, the cavity insert comprising: a body having: an internal surface defining, in use, at least a body portion of a molding cavity; an external surface defining, in use, at least a first portion of a cooling channel configure
What is claimed is: 1. A cavity insert for a mold stack of a molding machine, the cavity insert comprising: a body having: an internal surface defining, in use, at least a body portion of a molding cavity; an external surface defining, in use, at least a first portion of a cooling channel configured, in use, to direct a flow of coolant; and a mounting flange configured to support, in use, the body relative to a front face of a cavity plate, the mounting flange including: a member configured to define, in use, a second portion of the cooling channel, the member further defining a rear mounting extremity, and wherein at least a portion of the first portion of the cooling channel, in use, projects beyond the rear mounting extremity. 2. The cavity insert of claim 1, said cooling channel being a first cooling channel; wherein said external surface is further configured to define at least a second cooling channel. 3. The cavity insert of claim 2, wherein: said first cooling channel and said second cooling channel are joined by a connecting channel. 4. The cavity insert of claim 3, wherein said first cooling channel is associated with a first depth and wherein said second cooling channel is associated with a second depth; and wherein said first depth is greater than said second depth. 5. The cavity insert of claim 1, wherein: the cavity plate includes: a receptacle for receiving, in use, the cavity insert, the receptacle being configured to define, in use, a third portion of the cooling channel. 6. The cavity insert of claim 1, wherein the mounting flange and the member are separately formed. 7. The cavity insert of claim 1, wherein the mounting flange and the member are integrally formed. 8. The cavity insert of claim 1, wherein the body, the mounting flange and the member are separately formed. 9. The cavity insert of claim 1, wherein the body, the mounting flange and the member are integrally formed. 10. The cavity insert of claim 1, wherein the mounting flange defines an interface for accepting, in use, a sealing member, the interface being positionable, in use, between the mounting flange and the external surface. 11. The cavity insert of claim 1, wherein the external surface defines an interface for accepting, in use, a sealing member, the interface being positionable, in use, between the mounting flange and the external surface. 12. The cavity insert of claim 1, wherein the member defines an interface for accepting, in use, a sealing member, the interface being positionable, in use, between the member and the cavity plate. 13. The cavity insert of claim 1, wherein the cavity plate defines an interface for accepting, in use, a sealing member, the interface being positionable, in use, between the member and the cavity plate. 14. The cavity insert of claim 1, wherein: a first interface is defined between the external surface and the mounting flange, the first interface for accepting, in use, a sealing member; and a second interface is defined between the member and the cavity plate, the second interface for accepting, in use, a sealing member. 15. The cavity insert of claim 1, wherein: the member includes: a notch configured to be coupled with a protrusion, complementary to the notch, the protrusion and the notch being configured to positively locate, in use, the cavity insert relative to the cavity plate. 16. The cavity insert of claim 15, wherein said notch is associated with a first configuration and the protrusion is associated with a second configuration; the first configuration and the second configuration being so selected such that the notch fits securely within, when in use. 17. A mold stack of a molding machine, the mold stack comprising: a core assembly receivable, in use, in a core plate, the core assembly defining, in use, at least a core portion of a molding cavity; a gate insert receivable, in use, within a cavity plate having a front face; the gate insert defining, in use, at least a gate portion of the molding cavity; a neck ring located between the core assembly and a cavity insert, the neck ring configured to define, in use, a neck portion of the molding cavity; and the cavity insert including: a body having: an internal surface defining, in use, at least a body portion of the molding cavity; an external surface defining, in use, at least a first portion of a cooling channel configured, in use, to direct a flow of coolant; and a mounting flange configured to support, in use, the body relative to the front face of the cavity plate, the mounting flange including: a member configured to define, in use, a second portion of the cooling channel, the member further defining a rear mounting extremity, and wherein at least a portion of the first portion of the cooling channel, in use, projects beyond the rear mounting extremity. 18. The mold stack of claim 17, wherein: said core assembly includes: a core for defining, in use, the core portion of the molding cavity; and a lock ring configured to support, in use, the core relative to the core plate. 19. The mold stack of claim 17, wherein the neck ring is implemented as a core lock type neck ring. 20. The mold stack of claim 17, wherein the neck ring is implemented as a cavity lock type neck ring. 21. The mold stack of claim 20, wherein the neck ring partially defines a support ledge portion of the molding cavity. 22. The mold stack of claim 17, wherein the mounting flange defines an interface for accepting, in use, a sealing member, the interface being positionable, in use, between the mounting flange and the external surface. 23. The mold stack of claim 17 wherein the external surface defines an interface for accepting, in use, a sealing member, the interface being positionable, in use, between the mounting flange and the external surface. 24. The mold stack of claim 17, wherein the member defines an interface for accepting, in use, a sealing member, the interface being positionable, in use, between the member and the cavity plate. 25. The mold stack of claim 17, wherein the cavity plate defines an interface for accepting, in use, a sealing member, the interface being positionable, in use, between the member and the cavity plate. 26. The mold stack of claim 17, wherein: a first interface is defined between the external surface and the mounting flange, the first interface for accepting, in use, a sealing member; and a second interface is defined between the member and the cavity plate, the second interface for accepting, in use, a sealing member. 27. The mold stack of claim 17 further comprising a positioning member for positively locating the cavity insert relative to the cavity plate.
