Sepro New-Generation Robot Control System Completely Transforms Injection Molding Operations

Sepro Group is set to revolutionize the injection molding automation paradigm with its next-generation Visual 4 control system. This system features a modernized interface, making it more powerful, intuitive, and better connected than its predecessors.

The new platform will make its debut at K 2025 held in Düsseldorf, Germany, from October 8 to 15, 2025, and will be promoted across Sepro's entire range of robotic products in 2026.

Visual 4 is specifically developed for plastic injection molding applications and represents a significant advancement in Sepro automation control technology. The system maintains backward compatibility with existing Sepro equipment, requiring minimal training for operators familiar with previous Visual control systems.

Dirk Schroeder, Managing Director of Sepro Germany and Product Director of the Sepro Group, stated that the Sepro Group began manufacturing robots in the late 1970s and launched its first "CNC robotic arm" in 1981.

"From the beginning, we have been developing our own native control systems to meet the specific needs of our customers—plastic injection molders," Schroeder said. "This brand-new Visual 4 control system leverages all the experience we have accumulated over the years and now, with the help of modern technology, provides the performance, flexibility, and ease of use that today's molders need to succeed."

Layered solution

Visual 4 control will provide three configurations to meet different production needs.

Redesigned interface

The most obvious improvement is that the operator interface handheld unit is 25% lighter than the Visual 3 version. The weight reduction is primarily due to moving the CPU board from the handheld unit to the main robot control cabinet—this change also enhances data security by protecting key components from potential damage.

Visual 4 adopts a 10:16 aspect ratio portrait screen that is closer to a rectangle, providing a larger display area without increasing the overall size of the handheld unit. Its capacitive touchscreen (similar to screens in modern consumer electronics) offers higher responsiveness and supports multi-touch gestures. The interface design has been modernized with a simpler and less cluttered white background.

The touchscreen is complemented by 22 haptic shortcut buttons for quick access to sub-menus and basic commands such as start/stop cycles and axis movement. These buttons eliminate the need for a joystick, allowing for more intuitive multi-axis robotic motion.

Its powerful processor can control up to ten motion axes, making it ideal for managing complex injection molding units. These units involve multiple injection molding machines, robots in various configurations, and peripherals for secondary operations such as assembly, labeling, inspection, and packaging. The system can store up to 1000 mold programs for easy retrieval.

Enhanced Security and Compliance

The Visual 4 control system incorporates robust security features, including user profile settings and authentication profiles, to determine access rights to specific functions or applications. The system is fully compliant with existing Euromap standards and is designed to adapt to new standards anticipated in the coming years.

Sepro Group has over 50 years of experience in the industry, with more than 40,000 plastic injection molding machines equipped globally. Through its latest control systems, it continues to strengthen its position as a leader in the field of injection automation.
