The Russian plastics and manufacturing industry is evolving rapidly, and injection molding machines remain at the heart of production. To enhance operational efficiency, reduce energy consumption, and ensure precision, many factories in Russia are upgrading their equipment with AC drives (Variable Frequency Drives — VFDs).
This article explains the role of AC drives in injection molding machines, their benefits, features, and why they are becoming essential for Russian manufacturers.
Injection molding involves multiple stages: plasticizing, injection, cooling, clamping, and ejection. Each stage requires precise control of motor speed and torque. An AC drive regulates the speed of the electric motor, ensuring smoother operation and improved process accuracy.
Key Functions of AC Drives in Injection Molding
Motor speed control for screw rotation and plasticizing
Accurate pressure and injection speed adjustment
Improved clamping force efficiency
Reduced energy waste during idle cycles
Lower heat generation and longer machine lifespan
Energy efficiency is a major focus for many Russian factories due to rising electricity costs. AC drives can reduce power consumption by 30–60%, especially in machines with variable load cycles.
Precise motor control leads to:
Better melt flow consistency
More accurate injection speed
Reduced product defects
This is especially important for industries like automotive, packaging, and medical molding.
AC drives reduce mechanical stress on motors and pumps, which leads to:
By modulating motor speed, AC drives significantly reduce machine noise—an advantage for modern plants and robotics-integrated production lines.
Most AC drives support:
This makes them ideal for Industry 4.0–driven factories in Russia.
Popular Applications of AC Drives in Injection Molding
Servo-hydraulic injection molding machines
Hybrid injection molding machines
Extrusion and blow molding equipment
Plastic recycling and pelletizing lines
Features to Look for in an AC Drive
When choosing an AC drive for your injection molding machine in Russia, consider the following:
High torque at low speeds
Fast response time for pressure and speed transitions
Overload protection
Support for high ambient temperatures
Energy monitoring functions
Compatibility with existing PLCs
Russian companies in automotive, consumer goods, packaging, and electronics sectors are increasingly modernizing their production lines. AC drives help them:
Reduce production costs
Improve efficiency
Meet strict product requirements
Stay competitive domestically and internationally
The use of AC Drives for Injection Molding Machines in Russia is rapidly growing due to the clear advantages in energy savings, precision, reliability, and cost reduction. Whether you're upgrading existing equipment or investing in new machinery, AC drives offer a smart and future-ready solution for the plastics industry.
