Disclosed is a preferred mold design for producing plastic, molded preforms, which may be blow-molded into a container of a final, desired shape. A preferred mold includes a temperature control system for maintaining the preform mold at a desired temperature. The temperature control system can pass fluid through channels within the preform mold to cool plastic that is injected into the preform mold. In some arrangements, a mold comprises a neck finish mold, the neck finish mold configured to transfer heat away from the molding surface toward a channel conveying a working fluid. A heat transfer member may be at least partially positioned within the channel to transfer heat to the working fluid. In some embodiments, the mold comprises a high heat transfer material.

What is claimed is: 1. A mold defining a mold space configured to receive a moldable material, said mold comprising: a mold plate having a channel configured to convey a fluid, said channel defining an interior space; and a neck finish mold comprising: a mold body that includes a molding surface, the molding surface at least partially defining the mold space; and a heat transfer member at least partially disposed within the channel, said heat transfer member extending into the interior space of said channel; wherein a portion of the heat transfer member is in thermal communication with a fluid when a fluid is being conveyed within the channel. 2. The mold of claim 1, wherein at least a portion of the neck finish mold comprises a high heat transfer material, said high heat transfer material having a thermal conductivity that is greater than a thermal conductivity of iron. 3. The mold of claim 2, wherein the high heat transfer material has a thermal conductivity higher than 100 W/(mK). 4. The mold of claim 2, wherein at least a portion of the heat transfer member comprises a high heat transfer material. 5. The mold of claim 2, wherein at least 50% of the neck finish mold comprises a high heat transfer material having a thermal conductivity greater than a thermal conductivity of iron. 6. The mold of claim 1, wherein the neck finish mold further comprises at least one hardened material configured to reduce wear when the neck finish mold is moved relative to an adjacent surface, said hardened material being more resistant to frictional wear than an adjacent portion of the neck finish mold. 7. The mold of claim 1, wherein the neck finish mold further comprises a thermal insulating material configured to form a thermal barrier. 8. The mold of claim 1, wherein the neck finish mold comprises a thread split movable between a closed position and an open position. 9. The mold of claim 1, wherein the heat transfer member comprises at least one heat transfer enhancer configured to increase a ratio of surface area to volume of the heat transfer member. 10. A mold defining a mold space configured to receive a moldable material, said mold comprising: a first mold portion comprising at least one channel, said channel defining an interior passage and configured to convey a fluid; and a second mold portion comprising: a molding surface that at least partially defines the mold space; a heat transfer member, said heat transfer member at least partially extending into the interior passage of the channel of the first portion; and a mold body extending between the molding surface and the heat transfer member; wherein the heat transfer member is configured to transfer heat between the molding surface and a fluid being conveyed within the channel. 11. The mold of claim 10, wherein the second mold portion is part of a mold cavity section. 12. The mold of claim 10, wherein the second mold portion is part of a neck finish mold. 13. The mold of claim 12, wherein the neck finish mold comprises a thread split movable between a closed position and an open position. 14. The mold of claim 13, wherein the first mold portion forms part of a mold plate which is configured to receive a section of the neck finish mold. 15. The mold of claim 10, wherein at least a portion of the second mold portion comprises a high heat transfer material, said high heat transfer material having a thermal conductivity that is greater than a thermal conductivity of iron. 16. The mold of claim 15, wherein the high heat transfer material has a thermal conductivity higher than 100 W/(mK). 17. The mold of claim 10, wherein at least a portion of the heat transfer member comprises a high heat transfer material, said high heat transfer material having a thermal conductivity that is greater than a thermal conductivity of iron. 18. The mold of claim 10, wherein at least 70% of the mold body is a high heat transfer material. 19. The mold of claim 10, wherein at least 50% of the mold body is a high heat transfer material, said high heat transfer material having a thermal conductivity that is greater than a thermal conductivity of iron. 20. The mold of claim 10, wherein the second mold portion further comprises at least one hardened material configured to reduce wear when the second mold portion is moved relative to an adjacent surface, said hardened material being more resistant to frictional wear than an adjacent material of the second mold portion. 21. The mold of claim 10, wherein the second mold portion further comprises a thermal insulating material configured to form a thermal barrier. 22. The mold of claim 10, wherein the second mold portion forms an area of a mold core section. 23. The mold of claim 10, wherein the heat transfer member comprises an elongated member that extends at least partially into the channel. 24. The mold of claim 10, wherein the heat transfer member comprises at least one heat transfer enhancer, said enhancer configured to increase a ratio of surface area to volume of the heat transfer member. 25. The mold of claim 24, wherein the heat transfer enhancer comprises at least one selected from the following: a fin, protrusion, slit, bore, channel, groove, opening, recess, indentation, mesh structure and combinations thereof. 26. The mold of claim 10, wherein the first mold portion and the second mold portion are part of single unitary member. 27. A mold moveable between an open position and a closed position, the mold comprising: a mold space configured to receive moldable material when the mold is in a closed position; a mold plate having at least one channel configured to convey a working fluid therethrough, said channel comprising an interior space; and a cavity mold section comprising: a molding surface that defines a portion of the mold space; a heat transfer member, said heat transfer member at least partially extending within the interior space of the channel of the mold plate; and wherein working fluid directed through the interior space of the channel flows around a periphery of the heat transfer member; a body positioned, at least in part, between the molding surface and the heat transfer member; wherein at least a portion of the cavity mold section comprises a high heat transfer material; and wherein the high heat transfer material has a thermal conductivity that is greater than a thermal conductivity of iron. 28. The mold of claim 27, wherein the cavity mold section further comprises a hardened material configured to reduce wear when the cavity mold section is moved between a first position and a second position, said hardened material being more resistant to frictional wear than an adjacent material of the cavity mold section. 29. The mold of claim 27, wherein the heat transfer member comprises an elongated member that extends at least partially into the channel, such that a working fluid conveyed within channel contacts a surface of the heat transfer member to transfer heat between the elongated member and a working fluid. 30.
