Abstract: For observing a flow of molten resin in an injection molding apparatus, a transparent cylinder, which is formed of transparent glass or transparent plastic material, is used in place of a mold of the apparatus. Because filling the transparent cylinder with the molten resin up to the cylinder's full capacity will burst the cylinder, the molten resin injection is terminated on the way when the injected molten resin has occupied a predetermined percentage, in a range of 50–90%, of the total volume of the cylinder, so that a burst of the cylinder can be avoided. The transparent cylinder provides for an increased resin-flow observation range because of its transparency, and can be less expensive because it is formed of inexpensive glass or plastic. As a consequence, there can be provided an efficient resin-flow observing experiment apparatus at lower cost.
