Pad filler sandwich injection molding machine

In the traditional plastic injection molding machine, a group of composite nozzles and tube groups are added to form an independent double material tube. During the injection process, the two sols can be injected into the mold cavity through the common nozzle at the same time or at intervals to achieve a double material. The sol in the outer layer is called the skin layer material, and the sol in the inner layer is called the core material.
