We developed an innovative HMI concept (human-machine interface) and a sophisticated UX design for machines for the Nedschroef machine family in the field of cold forming equipment.
The project was characterised by its international focus: As part of our user research, we conducted surveys in three countries to develop a user-friendly HMI system.
In collaboration with SmartHMI, we integrated new features that were directly derived from user feedback, including QR code integration and machine module views. The project demonstrates how user research and HMI design can increase the efficiency and user-friendliness of machines.
The HMI design is closely linked to the machine branding, reflecting its visual identity throughout the interface. A key design feature is the integration of the machine's slanted lines into the user interface, ensuring a seamless visual consistency.
A notable UX feature is the adaptive operator view: the interface remains dark and minimalistic when the machine’s side door is closed and production is running. As soon as the operator interacts with the HMI—such as during error handling—the interface switches to a light mode, simulating the moment the user opens the door and “looks inside the machine.”
This approach demonstrates how thoughtful HMI design can enhance both user experience and the brand identity of industrial machines.
The new user interface improves machine operation with a historical message list that displays messages sorted by time and criticality, as well as a detailed display of errors that provides precise diagnostics and visual representations. Checklists and changeover instructions have also been integrated into the user interface, which increases user-friendliness and efficiency.
User-centredness also plays a central role in detailed processes. If the user wants to change complex, interrelated parameters, this is supported by a process graphic that visualises the changes and makes them immediately understandable. The product change wizard guides the user through the process step by step. Both features make a significant contribution to operating and process reliability and save a considerable amount of time.

Strama-MPS Maschinenbau GmbH & Co. KG, a renowned manufacturer of special machines and systems, is setting new standards in the field of human-machine interface (HMI) development in collaboration with our team. The implementation was carried out with the help of the Siemens Unified implementation tool, which we exploited to the full in close cooperation with Strama.
The latest generation of Coperion’s compounding and extrusion systems stands out particularly with a user-optimized operating concept. We developed both the visual design and the usability and user experience concept of the HMI. For the trade fair prototype we carried out the technical implementation using web technology.
The HMI from KIEFEL Packaging relies on self-explanatory illustrations and animations. It makes the highly complex technology easy to understand and thus facilitates the input of parameters. We developed the usability and user experience concept as well as the visual design for the HMI.
