When the solid bed is formed and begins to melt during transport, the molten material will pass through the gap δ and enter the liquid phase channel, while the unmelted solid particles cannot remain in the solid phase channel through δ.

Since the pitch of the main thread is not equal, the liquid phase groove is gradually widened from zero until the width of the entire groove of the homogenization section is reached, but the groove depth remains unchanged; the solid phase groove is narrowed from width to The width of the homogenization section becomes zero, but the depth of the groove is from the depth of the groove of the feed section to the depth of the groove of the homogenization section.

At the point where the liquid phase groove width is zero, the solid phase begins to separate, and the melting is completed at the point where the width of the solid phase groove is zero. The whole molten material is homogenized through the homogenization section, and is pressed into the machine head by constant pressure and constant temperature.
