A kind of manufacturing process for multiple-tubed injection of tread material which is to connect at least two runners with the mold under injection molding process. By setting different injection conditions, like pressure, speed, volume, and timing, the machine simultaneously injects different kinds of plastic, like PP, TPU, NYLON, etc., into the mold and melt connections between different material to produce the tread as a whole. The connection region of the tread can be adjusted by different ratio of the soft and hard material forming the front and back portion for different kinds of shoes.
