Smart maintenance application


SMS group is a global, leading partner for the metal industry. It is a family-owned business headquartered in Germany. Fast and flexible, SMS group develop individual and modular solutions – whether it’s the design of a new plant, Modernization, Digitalization, or Life Cycle Services.

SMS group’s R&D department wanted to improve the workflow of service support engineers and to create a smart maintenance system for caster machines.

Our goal

The purpose of the product is to provide plant employees from different departments with information about the current state and state history of the selected caster’s segment.

The core functionality of the system allows to easily monitor and provide efficient maintenance of a steelmaking machine.

We developed a Progressive Web App (PWA), that stores data in IndexedDB and has a two-way server synchronization. It allows the app to work in offline mode without access to server. The application collects data reports on the work of steelmaking machine segments and errors that occur during the work process.

Here’s how it works: a service support engineer can use the app to access and view statistics on the work of each caster’s segment, as well as get information about the current state and state history of errors (type and place of errors, when the issue was resolved and how, etc.). When an error occurs, e.g. when a caster’s segment needs to be replaced with a new one, a service support engineer can get it replaced and update the information on this specific segment in the app. Segment advisor application stores information about all the errors that have ever occurred, as well as when and how these issues were resolved.

This solution proved to be very useful for efficient maintenance of a steelmaking machines.

Our team collaborated closely with the engineers from SMS Group to bring our expertise and best practices together and create a product that will serve the service support engineers in the best possible way.

We used Plotly graphing library to create interactive, high-quality graphs. Stable and efficient application’s performance is ensured by a secure stack of reliable and proven technologies.


Segment advisor application was successfully presented at METEC 2019 trade fair in Düsseldorf, Germany. The platform received much praise from potential customers and got a lot of attention from the fair’s attendances.

The application is currently at an MVP stage and we are now working on extending its core functionality. SMS group plans to bring the product on the market soon for it to be ready to be installed at plants and factories across the world.
