A Packaging Solution from Exlar.
Powerful Roller Screw Actuators Replace Hydraulics.
The customer’s thermoforming equipment was using two opposing vertical hydraulic cylinders that came together to compress polystyrene sheets into foam trays at a high rate of speed. These trays are commonly found in grocery stores mainly in the meat department for meat and fish, fast food containers, restaurant take out containers, etc.
The customer wanted a “green” solution that eliminated the undesirable traits of hydraulics – such as mess from hydraulic fluid leaks, constant maintenance, etc. They were also seeking a higher production rate and improved product consistency.
The Exlar proposal consisted of an Exlar®FT35-0410 with high capacity screw, 2:1 parallel mount, oil ports with site gauge and a Schneider servo motor / drive.
The Exlar actuation solution nearly doubled the production rate from 20 cpm to 37 cpm. It also provides significantly better consistency of the finished product
