Why Energy Cost Has Become a Criterion for Choosing Equipment
Bundling stacks of corrugated boxes with PP band is a strapping process that repeats without pause on the shipping line. The longer the operating hours, the more the difference in power consumption of a single machine accumulates—feeding directly into the entire plant's operating costs.
JS SYSTEM's inline automatic PP banding machine, the AMB 1500 S/T, replaces the pneumatic drive method that had been standard for banding with full servo, so the same strapping job is handled with less power. In this article, we explain the structure from which these power savings arise.
The Key to Reducing Power Is Servo Direct Drive
A pneumatic banding machine generates compressed air with a compressor and transmits motion through cylinders. This process requires compression and transfer losses as well as constant pressurization, resulting in low energy efficiency. Because the AMB 1500 S/T directly controls its drive unit with 9-axis full servo, it uses power precisely—only at the moment the motion requires it.
As a result, it performs the same strapping job with about 30–40% less power than the pneumatic method. While maintaining a high-speed rate of 28 cycles per minute, power consumption stays at around 4kW—a structure that secures both processing speed and energy efficiency at once.

Pneumatic vs. Servo: What's the Difference?
The difference between the two methods goes beyond simple power figures. Because the drive principle itself differs, the energy-loss factors and maintenance conditions differ along with it. Below is a summary of the structural differences the two methods show in the strapping process.

Why the Savings Last Over Time
Energy efficiency is only meaningful if it is maintained not just at the time of installation but over long-term operation. Pneumatic systems lose efficiency over time due to air leakage and cylinder wear, but servo direct drive has few consumable and wear parts—so it rarely breaks down and sustains its initial efficiency for a long time.
Extreme Durability = Lasting Savings
With no pneumatic parts to wear out, servo drive is strong in long-term, uninterrupted operation. Continuing to run without any drop in efficiency is itself the surest way to reduce cumulative energy costs.

A Summary for Facility Managers
The power savings of the inline automatic PP banding machine AMB 1500 S/T are not an option but an effect that arises from its fundamental architecture of servo direct drive. It processes 28 cycles per minute with about 30–40% less power than pneumatic systems, and because it has few wear parts, this efficiency lasts a long time.
