LOW CONSTANT PRESSURE INJECTION MOLDING SYSTEM WITH VARIABLE-POSITION MOLDING CAVITIES

摘要

A kind of indexable mold system have multiple spraying systems be operable to by melt substantially constant pressure between about 6.89 5.0 megapascal (1,000 pound/square inch) and about 103.42 megapascal (15,000 pound/square inch) to the mold cavity insert of one group of at least one multi-cavity injection mold, work as fluid communication. The thermal conductivity of multi-cavity injection mold inserts is greater than 30 BTU/HR FT °F, almost without cooling channel therein.
