At a time in the economy when every penny needs to be well spent, I would like to draw attention to a problem we have as suppliers to the Brazilian industry. Of course, no businessman invests in their manufacturing facility thinking about wasting money, but that is what happens when maintenance is not followed rigorously.

The main point achieved when doing the homework on maintenance is the increased lifespan of machines. Make an analogy with your personal vehicle: if you drive and ignore the right times for oil, filter, and part changes, when it breaks down, you will certainly end up with higher costs and be without the car for a longer time.

To avoid this in the industrial context, there are two general models to be followed. Preventive maintenance is planned to occur at specific intervals. Predictive maintenance, which can also be periodically planned, uses measurements by devices to check the condition of the equipment and any necessary replacements.

Unfortunately, due to the condition of the equipment that arrives for restoration, it is evident that this care is not always taken. The result is an additional expense for the businessman. Trying to extend the lifespan of the equipment while ignoring maintenance is not a good idea.

It is important to remember that each industrial profile requires a type of planning for updates and replacements. In the case of the chemical industry, for example, each company must plan verifications according to the corrosive potential of the liquids they use.

A good example of equipment that requires periodic replacements, but is often neglected, is the diaphragm of valve seals. It must be in perfect condition to prevent leaks. The replacement should occur at determined intervals, as a break can compromise other valve components or even the entire system.

For these cases, the German technology that arrived in Brazil this year called the Conexo System fits perfectly. It allows for the attachment of chips to various equipment in the manufacturing unit, which gather information on machine composition, maintenance dates, and even the name of the responsible professional. This resource aligns with the transformation of Industry 4.0 – using data provided by the equipment itself for decision-making.

Whichever maintenance model is chosen, the main recommendation is: follow the installation instructions, whether from the website, catalog, or another contact from the manufacturer. This will bring savings and peace of mind to your production process.

With billions in loans, China is rebuilding Nigeria’s railway network from scratch, abandoning the British colonial tracks that have turned to scrap and creating a corridor of over 1,300 km to take the load off the roads of Africa’s largest economy.

China is building an artificial island in the middle of the sea, covering 20 km², to construct the largest offshore airport in the world, the Dalian Jinzhouwan. This $4.3 billion project is anchored on more than 3,000 pillars embedded in the rock beneath the ocean and is scheduled to open in 2035.

Forget petroleum-based asphalt: a Scottish company transforms 684,000 plastic bottles into one kilometer of road that is 60% more resistant and up to 10 times more durable, and the technology has already started replacing traditional asphalt in more than 30 countries.

A British company has installed in the middle of the ocean the world’s first floating platform that generates electricity 24 hours a day from the temperature difference between the surface and the depths of the Atlantic, without relying on wind or sun.

Austrian engineers have developed an inflatable concrete technology that transforms flat slabs into domes using only air pressure, eliminating scaffolding and temporary forms, and potentially changing the way bridges, tunnels, and curved roofs are constructed worldwide.

A robot named Walter does the work of five bricklayers per hour and can save the construction industry, where the average age of professionals is 46 years and almost no one wants to learn the trade anymore, in the United Kingdom.

Spain installs two giant pipelines 2.2 km off the coast to draw water from the Mediterranean and supply a megafacility capable of producing 200 million liters of drinking water per day.

How much would a Toyota Hilux cost without tax in Brazil? A diesel pickup truck priced at R$ 250,000 could drop to around R$ 127,000, showing why pickup trucks have become a luxury product in the country.

Windows without a prison-like appearance gain momentum in 2026 and promise to completely transform residential facades with more natural lighting, discreet security, increased property value, and a modern look without the burden of the old iron bars that dominated Brazilian homes for decades.

The largest precious metals mine under construction in the world is situated on a layer of ore 25 times thicker than common mines in South Africa, and has just connected a third shaft that will quintuple the extraction of platinum, palladium, and gold.

How much does it cost to make a radier? A shallow foundation can speed up the construction and reduce stages, but poorly compacted soil, excess load, and design errors can turn the concrete slab into cracks, structural settlements, and much higher expenses later on.
