TH140/SP servo energy-saving injection molding machine can produce injection molding products in the range of tile wrapping, switch box, plastic milk carton handle, etc. Take tile wrapping as an example, one mold can produce 10, four to five molds per minute. TH140/SP servo energy-saving injection molding machine is fast, time-saving and power-saving, easy to operate, and fully computer-controlled, which further enhances the competitiveness of customers' products. This series of models adopts a double-cylinder balanced injection system. The injection control adopts a displacement sensor of a well-known foreign brand to accurately control the injection weight. The pre-molding adopts a five-star motor, which can realize stepless speed regulation. The servo drive system adopts the international famous brand driver, and adopts the special control system of imported injection molding machine. The clamping part adopts an advanced five-pivot force-increasing structure with inclined rows. The clamping part has good rigidity, fast mold closing stability, and low pressure mold retention is accurate. It is very suitable for the injection production of small plastic parts.
