1.It produces three color sport shoes in one step to replace the former complicated procedures of lasting, gluing, sole attaching. 2.It can use P.V.C., N.B.R., T.P.R. and P.U. 3.The photoelectric digital control system with three patents divides the ejection quantity into sixteen sections, thus making the ejection precise. 4.The machine is controlled by the computer. 5.The computer controlled disc completely safe guards the system and ensures protection of the molds. 6.Molds shift automatically and no operators are needed, therefore improving safety and reducing damages to the molds that might be caused by manual operation. 7.Auto material passage clamping system reduces manpower and improves safety of the machine. 8.The disc is driven by the hydraulic system with hydraulic brakes, which enables the disc to move steadily and position accurately. 9.The hydraulic mold clamping system generates great clamping power, which results in no burrs and no permeation of colors. 10.The height of molds is adjustable, so this machine can produce sport shoes, canvas shoes, snow boots and safety boots. 11.Feeding screw is run by the hydraulic motor, the machine works speedily, noiselessly and is breakdown free. 12.Powerful ejection joins three colors of materials perfectly-no permeation of colors and great joint. 13.The unique screw rod design makes it easy to change the color of materials without any left-overs. 14.Lat pulling and California pulling can be produced at the same time. 15.Single-color, two-color, and three-color molds are suitable for this machine. Furthermore, this machine can produce single-color, two-color, and three-color, shoes simultaneously. 16.The hydraulic system and electric circuit system are separated. It is easy to maintain this machine.
