01
Component characterisation
Measure component performance by reproducing its loads, interfaces and actual operating conditions.
Our core business
Custom industrial test benches
Test equipment designed around your product, your constraints and the results you need to use.
At a glance
The requirement comes before the machine.
SEM designs and manufactures one-off and small-series test benches for SMEs, industrial companies, laboratories and technical centres. The architecture is defined from the loads to reproduce, cycle rate, interfaces and expected level of automation.
Hydraulic and fluid systems
Pneumatics
Mechanical and endurance testing

Our test-bench families
Three technologies, one integrated approach.
Each family has its own technical page. Select the main load or medium involved in your test to explore typical architectures, applications and our engineering method.
FLUID / 01
Hydraulic and fluid test benches
Reproduce real fluid operating conditions to measure, inspect and validate a component or fluid subassembly.
Explore this familyAIR / 02
Pneumatic test benches
Apply pressure, measure leakage, characterise flow or repeat a cycle with a reliable and traceable result.
Explore this familyLOAD / 03
Mechanical and endurance test benches
Apply a repeatable force, torque or movement to characterise a product and monitor its durability over time.

Use cases, not a fixed catalogue.
Each bench is defined for the product and test conditions. These examples show the types of requirement we can assess.
02
Endurance and cycle testing
Repeat mechanical, hydraulic or pneumatic cycles to monitor performance changes and identify potential drift.
03
Leak testing
Pressurise or evacuate the product, stabilise the test conditions and quantify leakage against the required threshold.
04
Functional validation
Sequence commands, measurements and safety functions to verify the complete behaviour of equipment or a subassembly.
05
Production testing
Make an inspection repeatable, guided and traceable for acceptance, production series or maintenance operations.
06
Qualification before commissioning
Prepare technical acceptance by recording the relevant variables, acceptance criteria and results for each test.
Our method
A clear and verifiable process.
- 01
Analyse the product and test
Product function, loads to reproduce, available interfaces and the expected result.
- 02
Define variables and tolerances
Pressure, flow, force, torque, displacement, temperature, accuracy and acceptance criteria.
- 03
Select the architecture
Circuit, structure, actuation, safeguards, instrumentation and required automation level.
- 04
Design and technical review
Drawings, schematics, component selection, risk analysis and interface approval.
- 05
Manufacture and integrate
Machining, welding, assembly, wiring, pipework, control and acquisition according to the project.
- 06
Acceptance and commissioning
Set-up, factory testing, documentation, installation and support during start-up.
