CASE STUDY:
Stop & Go Production Lines for Car Seat Assembly
COMPANY: Car seat manufacturer
INDUSTRY: Automotive
PROBLEM: Need to modernize the production line to improve efficiency, assembly precision, and adapt to new seat models.
CHALLENGE: Automation and modernization of the production line.
To increase efficiency and implement modern technologies, the Client decided on a comprehensive modernization of the production line for car seat assembly. A key element of the project was the implementation of a new electrical standard and PLC controller software using Siemens Simatic S7 with a Proface HMI system. Additionally, the system included a locking and inspection station for the rear seat, which required precise component integration and optimization of the production process.
SCOPE OF WORK: Comprehensive automation implementation
The MJ Group team, in cooperation with AUTOMET Group, carried out a comprehensive implementation that included:
- developing and implementing an electrical standard compliant with the Client’s requirements,
- designing and programming Siemens Simatic S7 PLC controllers and the Proface HMI system,
- full modernization of the control systems for the seat production line,
- integration and optimization of the rear seat locking and inspection station,
- complete commissioning and testing of the production line to ensure maximum efficiency,
- collaboration with the engineering department in France to ensure compliance with international standards.
SOLUTION: Modern industrial automation system
Thanks to the implementation of a new electrical and automation standard, based on Siemens Simatic S7 PLC controllers and the Proface HMI interface, MJ Group provided the Client with:
- increased precision and reliability of the assembly process,
- full control over every stage of production,
- the ability for fast diagnostics and remote system monitoring,
- improved ergonomics and an intuitive interface for production operators.
RESULTS AND BENEFITS FOR THE CLIENT
Thanks to the modernization of the production line, the Client achieved:
- increased production efficiency through reduced downtime and system optimization,
- improved quality and precision of seat assembly in compliance with international standards,
- enhanced workplace safety for operators,
- the ability to quickly adapt the production line to new car seat models,
- reduced operating costs thanks to the use of modern components and software.
