Curved Automatic Eva Foaming Injection Moulding Machine

EVA shoes machine


Product Character
  • Curved ranged, use smallest space. Easy to maintain and operate. The shortest moving
        distance of injection system, machine parts rare scuffed to extend machine's life and reduce the
        cost of repair and maintain.

  • Curved mold station range, turntable type injection base moving device, moving quickly, location
        precisely to increase producing effect.

  • Digital volume, ratio valve to increase the effects of hydraulic system, to reduce motor electricity
        waste to reduce product cost.

  • High accuracy hydraulic injection control system can depend on the features of products and
        material to set up 5 kinds different injection pressure and injection speed to raise product quality
        and reduce NG products.

  • Mold station close system adopt unique crank and piston complex construction, the speed of
        opening mold, the strong close mold power. When open mold and close mold will not cause the
        crank point of crank system damaged. It will increasse machine use life and reduce the cost of
        maintain and repair.

  • Accuracy temperature control system and high effective mold heated system, Not only mold
        temperature control accuracy but also the electricity waste very low, it is more 30% electricity
        saved than other general machine.

  • Injection control system adopt quantify and pressure control system, control accuracy, high
        stability and east to operate. The same mold hole the accuracy is ± 0.1 gm to raise products
        quality and  reduce NG products.

  • Jumbo injection volume injection system, single mold can produce 3~4 paors products, raise
        produce capacity and products competition.

  • All computerize control system, every machine operating terms clear and easy to learn and to
        operate, solve the training problems.

  • Capacious memory unit can save 299 unit mold product terms information, change mold, easy
        and quick to set up.
