Benefits for our clients (better performance)
鈼� No oil temperature changes, etc.
鈼� Infinite and very accurate control of Speed, Position and Force.
鈼� Since there are no massive ongoing problems, such as to repair oil hoses, cylinders or seals, electric actuators are very low maintenance.
鈼� Reduce Factory cost of expensive maintenance. Such as site engineers necessary training, complete risk assessments, authorize and book the downtime with the production planning.
鈼� Because of the precision patented Roller Screw Design of Exlar Actuators and increased contact surface, its lifetime is usually approx. 10 years.
鈼� Noise levels typically 30% lower with electric actuators system.
鈼� Longer tool life virtually guaranteed. No slamming of the mold hence less stress.
鈼� Electric actuators are faster and sooner start up as well as being possible to overlap movements. Compare to the same type of machine driven by servo-pump with a fastest cycle time of around 12 seconds, the electric technology can achieve to 6 seconds.
Akei Full electric machines provide a cleaner, more energy efficient and more environmentally friendly solution for blow molding industry. All of the 17 machine actuators (including Wall Thickness Control) had been replaced by servo actuator systems, below you can find a list of the benefits of using electrical actuators.
Environment friendly
(Benefits over Hydraulic systems)
鈼� Since there is no dirty oil contamination issues, electric linear motion is a CLEAN technology which preferred by industry.
鈼� No power consumption during stopped motion while hydraulic systems keep using energy to run the pump for maintaining pressure.
鈼� The noise level in the actuators is much lower.
Energy Saving
In rough calculation, comparing the motion energy consumption of variable pump technology to full electric technology in a cycle time of 12 seconds, the later is 86 % lower. If compared with a servo-pump system, it is 69 % lower.
Working principle
The motion for our machine functions is done by roller screw actuators.
鈼� Roller screws convert rotary torque into linear motion. As the power source is a servo motor, the position, torque and speed control is really accurate, simple to set up and is not affected by external variables like temperature.
鈼� Since there is more contact area between the screw and the planetary rollers, roller screw actuators are preferred over the balls screw actuator for achieving higher speeds, higher torque and longer lifetime.
