Project Description

PU TPU Safety Shoes Making Machine, SLM-6-09
Loop-line Double-color Sole One-step shaping with two different materials: TPU and PU, and it is application for safety shoes. The whole equipment is made up of loop-production-line, automatic quantitative TPU casting head, automatic quantitative PU casting head, hydraulic system, PLC microcomputer-controlled system and other auxiliary devices. TPU&PU casting head, material gun’s temperature, preparative material quantity, casting accuracy, mold temperature and pre-heating can all be controlled by PLC microcomputer, and because of that, it is shaped quickly after casting, which is efficient.
1. Designed for one-step casting of two-color sole with PU and TPU.
2. It is innovative to combine both TPU and PU casting heads, which is controlled by microcomputer accurately. The first-color TPU material will be heated accurately, quantified exactly and casted equably, and then the second-color PU material casted. It leads to adequate agglutination of the composite sole one-step shaping. The product is of abrasion-proof, acid-proof, slip-proof and static-proof, etc., which meets special requirement of safety shoes, top-grade casual shoes and tour shoes.
3. The machine, with automatic start/stop device, cast polyurethane sole continuously.
4. Using industry HIMI, controlled with expert PLC program and showed by touching-screen.
