How servo motors are transforming energy efficiency in injection molding machines. Injection molding machines are powerhouses, but they’ve historically been energy-intensive. Enter servo motors—a technology that’s not only making machines more precise but also dramatically more energy-efficient. Here’s how they’re changing the game: 1. Precision Control Servo motors allow for incredibly fine control over movement, ensuring that energy is used only when and where it’s needed. This results in less wasted power and higher part quality. 2. Reduced Energy Consumption Unlike traditional motors that run continuously, servo systems adjust dynamically to the machine’s requirements. This can reduce energy usage by up to 50%, especially in all-electric machines. 3. Lower Heat Generation By minimizing unnecessary energy use, servo motors generate less heat, reducing cooling requirements and overall operational costs. 4. Quiet and Smooth Operation Machines equipped with servo motors operate more quietly and with less vibration, contributing to a better working environment and lower maintenance costs. 💡 Takeaway: Servo motors aren’t just an upgrade—they’re a step forward in sustainable, efficient manufacturing. What’s your experience with servo-driven systems? #InjectionMolding #EnergyEfficiency #ServoMotors
Roman I’m glad you have made such an excellent overview. I have been retrofitting older machines with servo hydraulic pump systems for the last 4 years now. All machines show excellent signs of renewed performance and energy savings. People fear that this “new technology” can not be adapted to their old machines, but it is proven now with many successful installs. PS: I think back to 1980 when I started at Engel in Canada learning hydraulics with fixed pumps and A/C motors. I wish some of my teachers were still here to see a retrofitted old Engel machine. I would not have believed it if I didn’t see it myself.
After installing a new hydraulic system, I set up a new Servo setup pump in the machine, removed its screw hydraulic motor, and installed a mechanical gear with an induction motor. After that I had such amazing results that I was happy with all my hard work and I enjoyed it a lot. Now my hydraulic oil temperature remains at 28 to 30 and after that the machine's electricity consumption is saved by 50 to 55 to 60 percent. And it was a total surprise for me and for people like me elsewhere.
Now, a surprising thing here was that when our machine does the entire process, each function works for just a few seconds, but the screw system, which is the charging system, works for a long time. About 75 percent of the process time of each machine is spent on the screw process, so the most electricity is consuming on the screw process. So I still have challenges when I once again start to do something different and finally I did it!
There are many small industries in our country, so we have to face many problems within it. The biggest reason for this is that in our country, our industry does not have enough purchasing power to purchase new machinery, so we are working on old machines and we have to run these machines for a long time.
I think I've completely completed this now, I've gone into great depth, but if anyone still has any questions, they can ask me, feel free. Thank you Azhar Nawaz Novatech Engineers Plastic Turnkey Solutions Pakistan novatech6198@gmail.com
I removed the entire hydraulic system of the old machine and installed a new hydraulic system, attached the pump motor to it, and ran the machine. At that time, its energy consumption was being saved by 40% to 45%, and its temperature was dropped from 45 to 32 Celsius. And I'm shocked after this. But here one thing more
After that, I thought that by making some other changes in it, I could improve it even more, so I started researching more on it. After some time, my research was completed to the point of paper work, so I started thinking about doing it practically.
My first experiment was to remove the old induction motor pump and set up a new servo complete. After changing just this one thing, I saw a 10 Celsius drop in temperature and a 25 to 28 percent reduction in energy.

2wI completely agree with what you said and I have experienced it in a big way and due to this control, even the oldest machines start to feel new and start giving very good performance. The biggest reason for this is that the oil starts to stay cool and the hydraulic system, even if it is old, its performance becomes even better. So the machine must be mechanically fitted with the servo, then all its parts start giving very good performance.
