Claim Text:
1. An injection molding system comprising: at least one multi-cavity injection mold insert made of a metal having a thermal conductivity of more than 30 BTU/HR FT ° F.; a first injection system operable to deliver molten material at a substantially constant pressure of between about 6.89 megapascals (1,000 psi) and about 103.42 megapascals (15,000 psi) to a set of mold cavities of the at least one multi-cavity injection mold insert when in fluid communication therewith; a second injection system operable to deliver molten material at a substantially constant pressure of between about 6.89 megapascals (1,000 psi) and about 103.42 megapascals (15,000 psi) to the set of mold cavities of the at least one multi-cavity injection mold insert when in fluid communication therewith; a variable-position section to which a multi-cavity injection mold insert is secured, the variable-position section operable to position the set of mold cavities of the at least one multi-cavity injection mold insert into fluid communication with the first injection system when in a first orientation and to position the set of the at least one multi-cavity injection mold insert into fluid communication with the second injection system when in a second orientation; and a cooling system that is entirely confined within the variable position section and does not extend into any multi-cavity injection mold inserts of the variable position section.
