Application

The advantage of the rotary plastic injection molding machine is that it can choose double-station or three-station, which means it can have one upper mold, two or three lower molds. The operator puts the inserts here, and the clamping mechanism closes the mold to make the product. Improve efficiency, and save labor costs by completing the operation by one person.

 

Features

    • Clamping force: 45T to 500T.
    • Injection weight: 35g to 850g.
    • Vertical four columns clamping, vertical injection.
    • 1 top mold, 2 bottoms mold design, turn out the clamping area by Rotation.
    • Put insert part into outer mold and inner mold injection at the same time.
    • We can upgrade to servo motor for customer’s need, the actual energy save 50% ~ 70%.
    • Robots or workers only need to work in one position within the non-working mold, which improves safety.
    • The reserved position next to the machine allows easy addition of automation devices and the unique design of low noise machine operation.
    • This injection molding machine is suitable for molding plastic materials with inserts, such as motor rotor, lithium battery parts molding, click rotor, etc.

————————————————————-  Sample Display ————————————————————-

 

The electric energy consumption of the rotary vertical injection molding machine is mainly in the following parts.

  1. Hydraulic system oil pump.
  2. The heater.
  3. Circulating cooling water pump. In the injection molding workshop, generally multiple injection molding machines share a cooling water pump, of which the electric energy consumption of hydraulic oil pump motor accounts for more than 80% of the electricity consumption of the whole injection molding machine, so reducing its power consumption is the key to energy saving of injection molding machine.

 

What are the advantages of servo motor?

  1. Servo motor can reduce the system heat. The machine is working servo system to provide the pressure and flow value required by the load when not working servo system is at a standstill.
  2. Servo motor can save energy, for products with long molding cycle, it can save electricity to about 30%-40%.
  3. Servo motor is a fully closed-loop system, which can provide real-time feedback, detection, and correction of the system pressure and is more suitable for high-precision injection molding machines.
  4. The small size of the servo motor facilitates installation and maintenance and low maintenance costs afterward.

You can install a servo energy-saving system if you are also using a rotary vertical injection molding machine.
