Would you like to «take a picture» of the vibro-acoustic performances of your vehicle and compare it with the benchmark?

Do you need a diagnosis of a loss in the vibro-acoustic performances of your vehicle?

We can do it and work together with you in improving/optimising the perceived vibro-acoustic comfort.

Our expertise range from air-borne to structure-borne sound and we have a complete set of measurement devices and simulation softwares to support you.

The Acoustic Lab in STS acts not only as a partner in development of the parts that STS manufactures, but also as a trusted engineering service.


We have a very wide range of verticalized technologies, machines and processes; from felt to thermoforming, foaming, injection moulding and final assembling. All equipments are last generation updated and able to supply best performances in our field.
Continuous improvement activities are run according to World Class Manufacturing principles and methodology.



STS provide a full logistic service to its customers ensuring their satisfaction. STS Supply Chain is committed and structured to ensure right quantity,right timing and right place in delivery. To fulfill a further requirement STS has a global footprint in order to serve customers and minimize cost and leadtime.


STS wants to be your partner from the first idea to series production, and we believe that good partnership starts with a capable sales team. Our sales is well connected with the engineering. They understand the customer, market requirements, product design and manufacturing.

They know automotive industry, challenges and requirements for applications, materials, manufacturing processes and logistics chain. We promise, that they will try hard to be part of the solution for your challenges.



STS has a long experience of more than 40 years in acoustic and trim parts components with several levels of function integration like acoustics/esthetics, acoustics/thermal, acoustics and structure and their combinations.

The combined competencies in acoustic concept, material application, and advanced processes know-how in thermoplastic and -set injection molding allow us quick and reliable development processes.

Modern computer tools for simulation, analytic and geometry support the process.


Vibro-acoustic comfort is a real player in today’s vehicles. Final customers ask for «smart» vehicles, integrating information, safety, emotion: sound and vibrations are significant part of them, but the current weight constraints make the NVH design a complex field.

We are the right partner for you to accomplish this job and to find the «smart» solution.
