About us
In the Heart of Mechanics
STEM was founded in 2014, but it began earlier and in a garage: the two partners built racing motorcycles at their own expense, where a tenth of a millimetre decides whether the engine reaches the end of the race. It is the same standard by which production lines are assembled today. The company works for machine builders and for the plants that run them — paper mills, glassworks, ceramics, food lines, cogeneration plants — and is run directly by the two partners: one looks after the sites and the technical relationships, the other the organisation and the contractual side.
We work in teams of three or four, almost always away from home: they arrive with their own equipment and stay until the line is producing. One job closes, another opens, all year round — and it is that constant movement that lets us answer requests that come at short notice.
Our specialist field is industrial mechanical assembly, completed by the electrical, pneumatic and hydraulic connections needed to bring the plant into production. The plants and the industries change — paper, ceramics, glass, power. The method we bring to them does not.

The team
Whoever turns up knows what to do
On a long job the teams rotate, and that is how we can be on several fronts at once without keeping anyone waiting. What does not change is the way the work is done: they are all STEM employees, with the same training, the same certifications and the same safety rules. And the handover is ours to manage — whoever takes over is briefed by the team going off, not by the customer.
People first
No result comes beforeSAFETY
Prevention and organisation
Ready before we set foot in your plant
Before a team enters your plant, your contact already has the full set of documents: site safety plan, training and certification records, fitness-for-work assessments, the PPE issued and, for work abroad, the A1 form.
We send it complete when the order opens — nothing to chase, and no last-minute requests.

The everyday work
Mechanical installation, plant relocation, maintenance on lines that are still producing: this is the work that runs right through our year.
Precision alignment
Measured precision. Documented alignment.
We bring rolls, shafts, motors, gearboxes, couplings and cardan shafts into line, skewed axes included. The total station is used above all to line up complete production lines, where the tolerance is a tenth of a millimetre over tens of metres; laser systems work on the single coupling. We measure every deviation, correct the geometry of the machine and hand over the result: before and after, with figures you can check.
- Sokkia NET05AX II total station and Sokkia optical level
- SKF laser alignment systems for motors and cardan shafts
- Three Fluke instruments with software we wrote ourselves, for simultaneous electrical measurements
Structural steelwork
We build what has to go around the plant.
We make structural steelwork to suit the plant and the space around it: guards and machine casings, support structures, mezzanine floors, walkways, stairs, landings, handrails and service platforms. Everything is made to measure, starting from what the site actually needs, prefabricated in our workshop wherever that is possible and finished on your own factory floor — adapted, assembled and welded in place.
Revamping
You don't replace everything. You improve what matters.
We keep what works and act on what is no longer up to the job. Revamping brings mechanics, drives, guards and critical assemblies up to date without replacing the whole plant, improving reliability, safety and production continuity.
Revamping of a corrugated board line
Drive units overhauled, walkways and handrails rebuilt to standard, controls brought to the machine, signage and lighting for the bay.
Overhaul of an industrial roll
Journal and bearing seats reground, shoulders restored, flange shot-blasted and repainted, new bolting.
Industries
Experience across industries, specialist skills
We work across a range of industries, adapting our skills, our organisation and our methods to what each plant and each process actually needs. Every industry has its own procedures, its own timings and its own way of working: we set the job up around the production context and around the machine itself. From paper to glass, from ceramics to food, we work on plants and lines of very different kinds while keeping the same approach. The aim is to fit quickly into the customer's organisation and bring the job to a close with precision and continuity.
Where we work
18 paesi
Our experience crosses borders, industries and very different kinds of production. We work in Italy and abroad, alongside machine builders and industrial groups on the assembly, installation and commissioning of their plants. We bring specialist skills, organisation and the ability to adapt, working to the same method in different production, regulatory and logistical settings. From Europe to the Americas and on to the most distant markets, the aim does not change: continuity, reliability and a result that holds.

Industrial machinery installation · since 2014
We install. We relocate. We keep production running.
Mechanical and electrical installation of new industrial machinery. Plant relocation: dismantling, moving and re-assembly of complete production lines, new and used. Industrial maintenance on plants already in service. All of it inside the customer's own factory, in Italy and worldwide.

The everyday work
Mechanical installation, plant relocation, maintenance on lines that are still producing: this is the work that runs right through our year.
The rest is specialist work that calls for instruments of our own — and that is where we are strongest. Precision alignment, structural steelwork and welding on site, revamping.

A presence built on site
Every job starts from what the project actually needs. Our teams fit quickly into the way the site or the plant is run, working alongside the customer's engineers, production managers and staff. From the mechanical installation through to completion and commissioning, we work to keep continuity, precision and the agreed dates.
Confidentiality, always
We work with machine builders and industrial groups who put plants, technology and processes in our hands, often strategic ones. That is why we treat information, technical documentation and the work carried out on customers' sites with complete discretion, building professional relationships on trust, fair dealing and continuity over time.
