High-Speed Cap & Cup Molding
Engel shows how all-electric injection machines perform at 2-3 sec cycles.
Two production cells running Engel machines demonstrate capabilities in high-speed packaging. For cap molding, Engel is showing off the capabilities of its all-electric e-cap system in its own booth with a 460-ton e-cap 2440/420 US molding 26-mm HDPE beverage caps with tamper-proof bands in a 96-cavity old on a 2-sec cycle. The mold is from Z-Moulds of Austria, and a dry-air system to prevent mold sweating is from Eisbär Trockentechnik of Austria. Caps are optically inspected by a system from Intravis of Germany.A second cell is running four airline cups at the booth of Campetella Robotic Center of Italy (represented in the U.S. by Hunter Automation & Robotics, Sterling, Mass.). With injection speeds greater than 500 mm/sec, an all-electric Engel e-motion 740/240 T US toggle press is running well below 3-sec cycles with a mold from Fostag in Switzerland. The closed system for toggle levers and spindles is said to provide clean lubrication suited to the strict hygiene requirements of the food industry.
Using recycled content in packaging reduces the environmental footprint of the package and incentivizes recycling. There are plenty of technical solutions to overcome the barriers.
Many attendees in Orlando in a couple of weeks, walking the aisles and seeking out new equipment, materials and services will be taking a break from another very important search that consumes them back at their facilities: the search for people.
Robots are gaining the ability to monitor their internal systems for remote troubleshooting and predictive maintenance. They also are reporting production data.
