Case studies
Real problems, solved
Every case below happened on a stopped production line. The names, the equipment and the solutions are real.

What people whose line has stopped say
Testimonial translated from Portuguese.

Problem
Main line down because of a failing electronic unit, with a very long lead time for a replacement.
Our main line was down because of an electronic unit that was failing, and we had no time to wait for a new one, since the lead time was very long. TECSI stepped up straight away, lent us a unit and came out overnight from Saturday to Sunday, solving our problem at the Rio de Janeiro plant; today they are looking after me in Santa Luzia, MG. I highly recommend TECSI's service and partnership.

Problem
Rolling line down for 2 days with no way to pin down the cause of the fault.
Our rolling line had been down for 2 days and we could not pin down the cause of the fault. We got in touch with Diogo at TECSI, and he pointed us straight to a possible encoder fault; we sent in two damaged encoders we had in-house for repair at TECSI, and out of the two he managed to make one, which went back on the machine and ran immediately with no faults. Thank you, TECSI. Well done!

Problem
A water leak on the injection moulding machine damaged the HMI's screen and touch panel.
There was a water leak on an injection moulding machine at our company; the water reached an HMI that controls the machine's parameters and damaged its screen and touch panel. We removed the unit and sent it straight to TECSI, who gave us the best possible service, picked the unit up promptly and had people available to analyse it and carry out the repairs.

Problem
Machine running an old system, with faults on the HMI.
Our machine had an old system and problems with the HMI; a new system was developed, matched to the machine, and the HMI was replaced. The work came out excellent and went beyond what we had been led to expect.
Ricardo Neves
Maintenance Coordinator · Saint Gobain

Problem
Electronic board unavailable on the market, and the one on the machine running erratically.
We had a machine at risk because an electronic board was unavailable on the market, and the one running on the machine was working erratically. TECSI offered to help us and with their help we solved the problem quickly.

Maintenance Supervisor · Michelin

Problem
Production line down, waiting on a piece of equipment.
We had a small problem on a production line that unfortunately had to stop; we contacted the people at TECSI to see whether they had what we needed at that moment, and they replied right away and said they could help. This wonderful team looked after us promptly and in the best possible way, we bought the unit from them in perfect working order, and we are already back in full production.

Problem
Technical fault on the light tower of a Spartan fire truck.
First of all, our immense thanks for the almost instant response in solving a technical problem on a light tower belonging to a Spartan fire truck. TECSI alone managed to identify and solve the problem in just 1 day! On behalf of the Military Police, the Fire Brigade and the 2nd Battalion, our sincere thanks for the excellent immediate support and for the services provided!

Start with the diagnosisRepair vs replace
Before buying new equipment, do the math
For most breakdowns, repair gets the machine back faster and for a fraction of the cost, and it is the only way out once the line is out of production.

Frequently asked questions
How long does the quote take?
Within 12 business hours of the equipment arriving, with the diagnosis and a detailed commercial proposal before any work is done.
Do you repair discontinued equipment?
Yes. The repair is multi-brand and covers discontinued lines, with spare parts in stock such as IGBTs, encoders and resolvers, including for what is already out of production. When a direct repair isn't viable, we migrate to the successor platform.
Is the assessment free? Does the repair have a warranty?
The technical assessment is free and with no obligation to go ahead with the repair. Once repaired, the equipment comes back with a warranty and post-repair technical support.
How do I send in my equipment?
We take in equipment for bench repair at our lab in São Bernardo do Campo, SP, and we also provide on-site service. Start with a quote and the team will guide you through shipping.
Do you handle emergencies with the line down?
Yes. Emergency service is 24/7, with a team mobilized outside business hours, on weekends and holidays. During the repair there's loaner equipment at no cost, so the line doesn't stay down.
Which brands do you service?
Multi-brand repair for Siemens, Allen Bradley, Yaskawa, WEG, Mitsubishi, SEW, Bosch Rexroth and dozens more, discontinued lines included.
