At this year’s K2025 trade fair, Sepro Group is spotlighting a new generation of automation systems designed to meet the evolving needs of high-speed packaging production. The company is debuting its new S-Line robots and Visual 4 control platform, which promise faster cycle times, greater flexibility, and improved integration for injection molders working in packaging and related high-volume sectors.
The redesigned S-Line robots replace the previous S5 and 5X lines and are optimized for use with molding machines from 100 to 900 tons of clamping force. Designed with modularity in mind, the new models (S-15, S-25, and S-35) support 3-axis and 5-axis configurations, along with cleanroom-ready versions for sectors like food and medical packaging.
One of the standout improvements for packaging applications is speed. Sepro says the new robot structure, built with cam follower bearings, increases operating speed by 15%. The Y-axis demolding stroke is up to 40% longer, depending on robot size, which enhances performance for deep-cavity or multi-cavity molds often used in packaging. Payload capacity has also increased by 20% in standard models and up to 40% in heavy-load versions—essential for applications involving complex end-of-arm tooling or multi-part handling.
The Visual 4 control system, also debuting at K2025, will be integrated into all S-Line robots starting in 2026. The control platform has been fully redesigned, with a simplified pendant that’s 25% lighter than its predecessor and features a capacitive touchscreen for quicker, more responsive operation. The new screen is larger, with a vertical layout that offers a clearer view of robot status and programming menus.
Designed for better connectivity with peripheral devices, Visual 4 makes it easier to integrate robots into packaging lines with downstream tasks like stacking, inspection, or labeling. Three tiers of control—Visual 4, Visual 4 Plus, and Visual 4 Pro—offer scalable options depending on plant size and automation needs.
For high-throughput packaging operations, the ability to store up to 1,000 mold programs and control up to ten motion axes allows for fast changeovers and smooth coordination in multi-robot cells.
“Since the very beginning, we have been developing our own native control systems to suit the very special needs of our customers—plastics injection molders,” said Dirk Schroeder, Managing Director of Sepro Germany and Product Director for Sepro Group. “This new Visual 4 control takes advantage of all we have learned over the years and now takes advantage of modern technology to deliver the kind of performance, flexibility and ease-of-use molders need in order to be successful today.”
With both hardware and software innovations on display at K2025, Sepro is clearly positioning itself to meet the speed, precision, and integration demands of the modern packaging sector.
