For decades, pneumatic cylinders were the standard for driving piston filling machines. While reliable, pneumatic systems rely on compressed air, which can fluctuate in pressure, causing slight variations in fill volumes. Today, the gold standard for high-speed, high-accuracy production is servo liquid filling technology.
A servo motor is a highly advanced rotary actuator that allows for precise control of angular position, velocity, and acceleration. When integrated into a G-Tech liquid filling machine, the servo motor drives the piston with microscopic exactness. This means the machine knows precisely how far to push the liquid down to the millimeter, resulting in volumetric accuracy of up to +/- 0.5%.
Beyond accuracy, servo technology offers unparalleled software control. Through the touchscreen PLC, an operator can program the exact speed of the fill stroke. You can program the machine to fill the first 90% of the bottle rapidly, and then dramatically slow down for the final 10% to prevent splashing. This level of digital control is what separates average factories from world-class manufacturing facilities.
