||PressOne Electric Insertion Machine
||Traditional Hydraulic Insertion Machine
||Servo motor-driven ball screw
||Hydraulic motor, pump, and fluids
||Low. Average power consumption is less than 0.4 KW. It consumes less electricity, as it only uses energy when in motion.
||High. Average power consumption up to 10 KW. Hydraulic insertion machines consume more energy than electric ones because they need to keep the oil pump running even when they are not working. This makes them less efficient and expensive to run and maintain.
||High. Electric insertion machines can adjust the force and stroke of the ram with high precision and repeatability. The servo motor-driven ball screw can control the speed and position of the ram with minimal backlash or error. Electric machines allow you to control the ram by position or tonnage. There is no “overtravel” or “undertravel” due to hydraulic viscosity fluctuations.
||Low. Hydraulic insertion machines have difficulty adjusting the force and stroke of the ram with high precision and repeatability. The hydraulic pump can cause variations in pressure from heat build-up or oil viscosity changes. Many Hydraulic insertion machines are programmed by tonnage and not position. Hydraulic viscosity fluctuations occur allowing for the possibility of “overtravel” or “undertravel” of ram.
||Faster. Electric insertion machines can operate faster and more smoothly than hydraulic ones. Electric machines have “direct positioning” with immediate accelerations/decelerations, due to the ball screw/servo design. Electric insertion machines can also be integrated with a robot arm or a conveyor belt for automated loading and unloading of workpieces.
||Slower. Hydraulic insertion machines operate slower and less smoothly than electric ones. Hydraulic machines use fluids, valves, and the transfer of electrical signals, which create some lag in speed changes and accelerations.
||Positive. Electric insertion machines are more environmentally friendly because they consume less energy and do not use hydraulic oil, which can contaminate surrounding areas.
||Negative. Hydraulic oil can cause environmental problems if it leaks, spills, or contaminates the surroundings. Hydraulic oil also needs to be disposed of properly after it is used up, which adds to the cost and waste of the machine.
||Low. Electric insertion machines have fewer moving parts and do not require hydraulic fluid changes, spare parts, valves, or maintenance expenses.
||High. Hydraulic insertion machines have more moving parts and require hydraulic fluid changes, spare parts, valves, or maintenance expenses. Hydraulic insertion machines have more components that can wear out or break down over time and need constant servicing and repairs.
||High. Electric machines eliminate the need for hydraulic fluid changes, spare parts, valves, and maintenance expenses, saving time and money for the user.
||Low. The high maintenance cost and lower accuracy and productivity of hydraulic insertion machines make them less cost effective for the user.
