How VFDs Optimize Plastic Machinery for Better Performance
2025/06/05


A variable frequency drive (VFD) can enhance plastic machines significantly. It saves energy, controls processes more precisely, lowers costs, and lasts longer. For example, VFDs can reduce machine downtime by 45% and breakdowns by 75%. Key applications of VFDs include improving efficiency in manufacturing processes. Canroon’s smart tools help factories work better with modern automation.


Key Takeaways

  • Variable frequency drives (VFDs) help plastic machines save energy. They can cut energy costs by as much as 50%.

  • VFDs let you control motor speed and power exactly. This improves product quality and reduces mistakes during manufacturing.

  • VFDs make machines last longer by lowering wear and tear. This means less fixing is needed and machines work more reliably.

Variable frequency drives (VFDs) help plastic machines work better. They control motor speed and torque, improving efficiency and product quality. Let’s look at how they help in injection molding, extrusion, and blow molding machines.

Injection Molding

Injection molding needs precise motor control for good plastic parts. VFDs adjust motor speed and pressure in real-time. This keeps material flow steady and reduces defects and waste.

VFDs also prevent sudden starts and stops, protecting machine parts. For example:

Using Canroon’s VFDs, you get better precision and save energy. These drives are high-quality and affordable for modern factories.

Extrusion Machines

Extrusion machines need steady motor speed for even material flow. VFDs provide this control, ensuring consistent output and quality. This improves the uniformity of extruded products.

VFDs also let you adjust settings based on material needs. For example:

  • They keep motor speed steady to control temperature better.

  • Accurate speed changes reduce defects and improve product quality.

Canroon’s VFDs are reliable and cost-effective for extrusion machines. They are a smart choice for manufacturers.

Blow Molding Machines

Blow molding machines need precise motor control for even walls. VFDs help distribute material evenly and reduce waste.

They also protect machine parts by lowering mechanical stress. For example:

  • Smooth speed changes extend the life of pipes and valves.

  • Less wear on pumps and fans makes them last longer.

Canroon’s VFDs improve performance, cut maintenance costs, and save energy. They are designed for plastics manufacturing and offer great value.


Benefits of Variable Frequency Drives

Energy Efficiency

Variable frequency drives (VFDs) help plastic machines use less energy. They control motor speed and torque to avoid wasting power. Motors only use the energy needed for each task, saving electricity.

Tip: Switching to liquid-cooled VFDs can save a lot of energy. For example, one factory saved $20,000-$30,000 a year on electricity after using these drives.

Energy checks show VFDs can cut power use by 5% to 15%. In some cases, savings go up to 65%, especially when controlling air compressors, pumps, or fans. These parts use about 25% of factory energy, so VFDs are important for saving power.

Enhanced Precision and Control

VFDs give better control over motors. You can change speed, torque, and direction easily. This helps machines work smoothly, reducing mistakes and improving product quality.

Modern VFDs use smart systems to save energy and improve motor performance. For example:

  • Smooth motor starts and stops protect machine parts and make them last longer.

  • Temperature control is more accurate, keeping material flow steady and cutting waste.

Note: New technologies like GaN and SiC make VFDs faster and more efficient for factories.

Cost Savings and Extended Equipment Lifespan

Using VFDs saves money and makes machines last longer. They slow down motors to reduce wear and tear, cutting repair costs. For example, lowering fan speed can make bearings last twice as long.

One company saved 34% on energy by adding VFDs to their machines. This helped them keep $0.50 of every dollar saved on heater bands. Grants, like $50 per replaced horsepower, make VFDs affordable for factories.
