Flexibility, performance and cost, (both capital and operating) have always been key factors in today’s expanding manufacturing marketplace. For decades hydraulics and mechanical presses were the only options for high-speed, high-force assembly and forming applications. More recently hydra-pneumatics and servo based systems have emerged as viable low-cost alternatives. So which technology is best suited for a specific application? We highly recommend contacting Aries Engineering application-specific information but the following topics can serve as a guideline towards the correct usage.

Aries Engineering is the only manufacturer Headquartered in North America offering both hydra-pneumatic and servo driven solutions.

Servo-Based Technology - HyperCyl-EMA

Capability: Provides exceptional control over force, speed and distance characteristics. Requires the use of a full PLC/PC based electrical panel and 230V/460V. Best used for push-to-distance or push-to-force applications, push/pull applications and where Extreme repeatability is essential. Signature analysis, data logging, part history, trending and root cause analysis options are also available for added functionality and tracking.

Reliability: Servo technologies are inherently capable and sizing them appropriately is crucial. Expected lifetime is from 1 Year to 5 Years, configured for any particular application. Long-Term Reliability coincides with maintenance schedules.

Speed: Up to 16.00 in/sec with an extremely high rate of repeatability. Requires a deceleration setting before Contact and Home to maximize tooling and screw life.

Forces: 1-10 Ton in Ball Screw configurations (BS1 & BS2) with a medium dynamic load rating; 1-25 Tons in the Roller Screw configuration with a high dynamic load rating.

Maintenance: 3-6 month lube schedule & periodic belt tension check dependent on usage and environment.

Cost: Can be higher initial cost than comparable Hydraulics. Energy efficiency and ROI achieved with low down-time, low noise pollution, ZERO environmental pollution, comparable energy usage to hydraulics without the mess.

Hydra-Pneumatic Cylinders - HyperCyl

Capability: Utilizing 2 pneumatic valves for operation and a FRL greatly reduces start up time. Cylinders are available in 5 design configurations and 11 standard sizes. Best used for; crimping, dimpling, peening, swaging, inserting, clinching, pressing, staking, piercing, punching, marking, bending and forming. When coupled with the IntelliCyl option, (load cell and LVLT) force distance monitoring is available.

Reliability: (MTBS) Mean time between service interval of approximately 4-5 million cycles because down time is not an option. LIFETIME warranty on all HPI – HPS – HZ – HZS – HPT cylinders, 1-Ton through 200-Ton.

Speed: Fast Approach speeds similar to that of a pneumatic cylinder (6 in/sec – 10 in/sec) and High Pressure speeds similar to that of hydraulic cylinders (1.0 in/sec – 2.0 in/sec).  

Forces: 1-200 tons of output force using 30-100 PSI shop air.

Maintenance: 20 million cycles before seals require replacement. Field serviceable by maintenance techs and 24 hour Hypercyl assistance is available. Periodic maintenance depends on application and environment.

Cost: More expensive than Pneumatic cylinders but offers the same Clean, Quiet & Self-Contained operation. Less expensive than hydraulic and mechanical systems for both short & long-term investments.
