What is claimed is: 1. A mold stack comprising: a first molding cavity defining component, a second molding cavity defining component and a third molding cavity defining component, with the second molding cavity defining component being located, in use, in-between the first molding cavity defining
What is claimed is: 1. A mold stack comprising: a first molding cavity defining component, a second molding cavity defining component and a third molding cavity defining component, with the second molding cavity defining component being located, in use, in-between the first molding cavity defining component and the third molding cavity defining component; at least one of the first molding cavity defining component and the third molding cavity defining component being associated with a respective compensator, the respective compensator configured to allow the at least one of the first molding cavity defining component and the third molding cavity defining component to align itself relative to the second molding cavity defining component. 2. The mold stack of claim 1, wherein both the first molding cavity defining component and the third molding cavity defining component are associated with the respective compensator. 3. The mold stack of claim 1, wherein said first molding cavity defining component comprises a core insert and wherein said respective compensator comprises a compensator associated with said core insert to permit a degree of movement to said core insert. 4. The mold stack of claim 3, wherein said degree of movement comprises at least one of a degree of axial movement and a degree of lateral movement. 5. The mold stack of claim 1, wherein said first molding cavity defining component comprises a core insert including a core base for defining, in use, a portion of a molding cavity and a core support for supporting, in use, said core base relative to a core plate of a molding system; and wherein said respective compensator comprises a compensator associated, at least partially, with said core support to permit a degree of movement to said core base. 6. The mold stack of claim 5, wherein said degree of movement comprises at least one of a degree of axial movement and a degree of lateral movement. 7. The mold stack of claim 5, wherein said compensator comprises at least one of: a compensating portion defined in said core support; and a sliding interface defined, in use, between said core base and said core support. 8. The mold stack of claim 7, wherein said compensating portion is implemented as a resilient portion. 9. The mold stack of claim 5, wherein said compensator comprises a spring connection disposed between said core base and said core support. 10. The mold stack of claim 7, wherein the core insert further comprises a core clearance defined between the core base and the core support. 11. The mold stack of claim 1, wherein said third molding cavity defining component comprises a cavity insert and wherein said respective compensator comprises a cavity clearance defined between the cavity insert and a cavity plate. 12. The mold stack of claim 11, wherein said respective compensator further comprises a flexible fastener for coupling said cavity insert and the cavity plate. 13. The mold stack of claim 11, wherein said third molding cavity defining component further comprises a gate insert and wherein said respective compensator further comprises a gate insert clearance defined between the gate insert and the cavity plate. 14. The mold stack of claim 13, wherein said respective compensator further comprises a flexible fastener for coupling said gate insert and the cavity plate. 15. The mold stack of claim 1, wherein said second molding cavity defining component comprises a stripping ring. 16. The mold stack of claim 1, wherein said second molding cavity defining component comprises a split mold insert. 17. The mold stack of claim 16, wherein said split mold insert is associated with a retaining structure configured to positively locate, in use, said split mold insert. 18. The mold stack of claim 17, wherein said retaining structure comprises a relief element configured to provide, in use, a degree of flexibility to the retaining structure. 19. A mold incorporating the mold stack of claim 1. 20. A molding system incorporating the mold of claim 19. 21. A method of aligning a mold stack, the mold stack including a first molding cavity defining component, a second molding cavity defining component and a third molding cavity defining component, with the second molding cavity defining component being located, in use, in-between the first molding cavity defining component and the third molding cavity defining component; at least one of the first molding cavity defining component and the third molding cavity defining component being associated with a respective compensator, the method including: positively locating the second molding cavity defining component; aligning the at least one of the first molding cavity defining component and the third molding cavity defining component relative to the second molding cavity defining component. 22. The method of claim 21, wherein the first molding cavity defining component is associated with a first compensator and the third molding cavity defining component is associated with a second respective compensator, and wherein said aligning comprises: aligning both the first molding cavity defining component and the third molding cavity defining component relative to the second molding cavity defining component. 23. The method of claim 21, wherein said second molding cavity defining component comprises a split mold insert associated with a retaining structure and wherein said positively locating the second molding cavity defining component comprises: urging the split mold insert into an operational position using the retaining structure. 24. The method of claim 22, said mold stack comprising a first mold stack and a second mold stack and wherein said positively locating the second molding cavity defining component and said aligning the first molding cavity defining component and the third molding cavity defining component relative to the second molding cavity defining component are executed substantially independently for each of the first mold stack and the second mold stack. 25. A mold stack comprising: a first molding cavity defining component, a second molding cavity defining component and a third molding cavity defining component; one of the first molding cavity defining component, the second molding cavity defining component and the third molding cavity defining component configured to be used, in use, as an alignment master; and at least one of the other ones of the first molding cavity defining component, the second molding cavity defining component and the third molding cavity defining component being associated with a respective compensator, the respective compensator configured to allow the at least one of the other ones of the first molding cavity defining component, the second molding cavity defining component and the third molding cavity defining component to align itself relative to the alignment master.
