A product the SIMEPROD engineering team is particularly proud of:

>> Manual guns with high-force capacities and ergonomic design.
>> Robotic guns with automatic tool-changing capabilities.
>> Single-point guns for welding gantries.
>> State-of-the-art medium frequency welding controls.

Automation
of Processes in Railway Engineering

Our extensive experience in Railway Engineering, combined with our proven track record in the highly competitive automotive sector, enables us to automate processes previously unheard of in the railway industry, such as predictive maintenance management and route planning. This capability allows us to significantly boost the productivity of our clients in an increasingly demanding and competitive sector.

We have successfully participated in turnkey projects for CAF, STADLER, TALGO, ALSTOM, and TIER 1-2 companies across Europe, the USA, Mexico, and Brazil.

Automation of Processes in Railway Engineering

>> Multi-Tool Gantries for Automatic Welding of nearly all subassemblies of Austenitic Steel Train Bodies.

A unique system, 100% designed by Simeprod, featuring single-point welding and welding guns with automatic tool-changing capabilities managed by anthropomorphic axes. This innovation enables welding a train body at record speed without manual intervention, delivering unmatched quality compared to conventional systems.

>> Welding Gantries Adaptable to Collaborative Robots (COBOTS) for welding aluminum train bodies, equipped with modern joint-tracking systems and automated accessories.

>> Self-Leveling Frame Turners exclusively designed by Simeprod.

>> Automated Assembly of Bogies.

>> Design and Manufacturing of tools for train body finishing and interiors, including air conditioning, electrical installations, seat assembly, window installation, and more.
