How Are Air Springs Used in Different Types of Injection Molding Machines?
Vibration is a hidden threat in injection molding. It affects product precision, shortens machine lifespan, and creates workplace noise. Air springs provide a reliable solution by isolating vibration and enhancing machine stability.
Air springs are widely used under various injection molding machines to control shock, noise, and dynamic loads. Their adaptability, durability, and tuning capability make them ideal for vibration isolation.
Keep reading to explore how air springs benefit every type of injection molding machine.
Which Types of Injection Molding Machines Can Use Air Springs?
Air springs are suitable for most modern injection molding machines, including horizontal, vertical, rotary, and servo-driven models.
They are particularly effective in thermoplastic injection molding, multi-component machines, and high-speed electric molding systems.
Using air springs in these machines enhances floor stability and reduces vibration impact on mold precision and hydraulic systems.

Where Are Air Springs Typically Installed on Injection Machines?
Air springs are installed beneath the injection molding machine’s base or footplates.
This location allows direct absorption of operational vibration and minimizes structural noise transmission.
Strategic installation at each load-bearing point ensures proper leveling and shock absorption.
This setup works even better when integrated with air control valves or leveling systems.
What Are the Advantages of Air Springs Over Rubber Pads or Metal Springs?
Air springs outperform traditional mounts with superior vibration damping and load adaptability.
They maintain optimal performance across varied tonnages by adjusting internal air pressure, which offers consistent performance across operating speeds.
Unlike static rubber mounts, air springs provide isolation over a wide frequency range, making them ideal for precise molding operations.

Can Air Springs Improve Injection Accuracy and Product Yield?
Yes. Air springs stabilize the base of the injection machine and reduce micro-vibrations.
This leads to more accurate mold closing, better alignment, and lower product rejection rates.
Factories using air springs report fewer short shots, flash issues, and mold wear—especially in high-precision plastic molding.
Can Air Springs Handle the Dynamic Load of High-Speed Injection Molding Machines?
Absolutely. Air springs are built for dynamic load response.
They handle rapid pressure changes from servo-controlled or electric injection machines without performance loss.
Even in 800–2000-ton units with fast injection cycles, air springs reduce stress on machine frames and increase motion stability.

How Are Air Springs Integrated Into Modern Injection Molding Systems?
In advanced production lines, air springs are part of a smart foundation system.
They integrate with auto-leveling valves, sensors, and central air control to maintain perfect machine positioning.
This setup improves mold accuracy and reduces downtime from manual adjustments—essential in smart factories and automated molding lines.
You can integrate an FP crimped air spring system with auto-leveling valves for stable performance.
How to Select the Right Air Spring for Your Injection Machine?
Choose based on total machine weight, footprint, and operating frequency.
Use load-per-point calculations to determine the correct air spring capacity and damping range.
At Songjiangflex, we offer custom solutions for all tonnage levels and machine types.

How Do Air Springs Help Reduce Noise in Injection Molding Plants?
Air springs reduce structure-borne and airborne noise by isolating machine vibration from the floor.
This helps maintain quieter factory environments and meets industrial noise standards.
Especially for large hydraulic machines, noise can drop by 5–10 dB after installing air spring vibration isolators.
Can Air Springs Work With Automatic Leveling Systems?
Yes. Air springs are often connected to automatic leveling valves or controllers.
This ensures the injection molding machine remains level, even if the load shifts or floor settles over time.
Automatic air leveling improves molding repeatability and minimizes stress on machine joints.
What Feedback Do Injection Molding Users Give About Air Springs?
Industrial users report increased mold accuracy, lower maintenance costs, and smoother machine operation.
Air springs also protect concrete floors and eliminate the need for anchor bolts in many setups.
A customer in the UAE replaced traditional pads with FP-type air spring mounts from Songjiangflex and saw a 30% improvement in product consistency.
Air springs provide a flexible, high-performance solution for vibration isolation in injection molding machines.
