Title: MANUFACTURING METHOD FOR MULTIPLE SPRUE BUSHES
Abstract:
In order to provide a method for precisely manufacturing, at substantially the same timing, multiple sprue bushes capable of suitably cooling the entirety of a molten resin raw material in a raw material resin flow path, one embodiment of the present invention provides a manufacturing method for multiple sprue bushes, the method comprising setting respective molding parts on multiple base parts, wherein: each of the multiple base parts includes a raw material resin flow path, and a cooling medium flow path provided around the raw material resin flow path; and, prior to setting of the molding parts, the respective positions of the multiple base parts are specified on a virtual XY-coordinate plane on the basis of positional information about at least the raw material resin flow path or the cooling medium flow path.
