System, method, and apparatus for molding precision parts

A melt distributor has an orifice for receiving molten plastic. A plurality of melt distributor channels are in fluid communication with the orifice and each of the plurality of melt distributor channels have substantially the same length and cross-sectional volume. A plurality of injection tips terminates each of the melt distributor channels. A channel passes through each of the injection tips, a first end which is in fluid communication with a corresponding one of the melt distributor channels and a second end of which is for connecting to a corresponding injection port of a corresponding mold. Molten plastic flows at substantially equal flow rates and timing through each of the melt distributor channels and through each of the injection tips, entering each of the two injection ports of each mold at substantially the same timing, flow rate, and temperature.
