S-8 Servo

LOG S-8 Servo Injection Molding Machine is energy efficient, precise, and versatile.  Along with its KEBA i2880 control platform, the unit is easy to program, reduces set-up time, maintenance, and operation costs.   The  energy savings of the servo unit is 35% – 75% of a standard pump motor.

S8 Servo injection molding machine offer the superior clamping force of hydraulic machines and the precision, repeatability, energy savings, and reduced noise of electric machines.   S8 Servo injection molding machines use a servo motor coupled to a hydraulic pump to circulate the oil used to provide the hydraulic pressure which actuates the components of the machine. The use of a servo pump allows for continuous adjustments to the actual power requirements, low emissions, less noise, and energy savings.

Servo motors have a faster response time than standard hydraulic pumps, which leads to faster cycles and decreased cycle times. They also offer more precise controls and a more consistent process due to the encoders that track each turn to the exact rotation position.

Advantages of the LOG S-8 Servo Injection Molding Machine include continuous adjustments allowed by the servo pump; diversity of part designs; use of a two-clamp system over toggle; median upfront costs of the three machine options, while providing the most long-term savings; closed-loop process for quicker response times; lower temperatures that require less cooling, leading to longer oil and machine life; and faster ROI.
