Difference between Ordinary Injection Molding Machine and Servo Injection Molding Machine
The biggest difference between the two is the motor (also known as motor), which means that they are driven in different ways.
● Ordinary injection molding machine: Continuous operation, the motor keeps rotating even when the machine movement stops.
● Servo injection molding machine: Each different movement will be powered using the appropriate amount of power, and since the machine is not moving, the servo motor will stop completely.
In a servo injection molding machine, a servo motor replaces a normal alternating current (AC) motor. Since the servo motor itself is a closed-loop control system, it can be controlled by providing the appropriate torque according to the change in pressure value. Servo motors can be used for all drives of the machine such as pump motors and injection drives.
Common injection machines have the speed and power to use AC motors (running at a fixed speed) and various types of pumps. While they are still cheaper than servo motors or all-electric, they consume a lot of power and are therefore more expensive to run. Ordinary injection molding machines can be modified with variable speed control of the motor to improve energy efficiency. Servo motors have many advantages over regular AC motors. They can be controlled more accurately, use less power, weigh less, and are quite. On the other hand, they are quite costly.
Advantages of Servo Injection Molding Machines
Nowadays, servo injection molding machines have been widely accepted by users and are becoming more and more versatile. Servo motors have many advantages:
● Fast pressure response, quick start-up to 0.05 seconds
● Compared with traditional injection molding machines, the system response speed is 2-3 times faster than traditional machines.
● Fast and precise running speed, which greatly improves or improves the production environment and productivity.
● The precision of repetitive products can be increased to more than five thousandths of an inch, meeting the requirements of ultra-precision injection molding
● The servo motor gets the signal and then fills the hydraulic oil, generating less heat and lower temperature of the hydraulic oil, saving a lot of cooling water.
● Fast response speed and short cycle time improve productivity.
● Servo injection molding machine can save 50-80% of electricity.
