Espansi Tecnici S.r.l. was founded in 1985, last born of a group of companies belonging to the Gaggelli family, completing the production of a wide range of diversified products.
Structured starting for the production of expanded polystyrene from a block, with the entire production cycle made internally, from the expansion to the cutting and / or shaping, up to the recycling of the production waste, the Company has always distinguished itself for the dynamism with which it has been able to adapt to the evolutions of the market, knowing how to accept every challenge with the ability and courage to continuously invest in new technologies and human resources.
The geographical location, in the heart of a thriving motorhome district, has made Espansi Tecnici specialize more in that sector, from the care of the quality of the product to the realization of specific equipment for ancillary work, from the establishment of a highly specialized technical office to meticulous training of personnel in production and, above all, in quality control, with a well-equipped testing laboratory behind them. Espansi Tecnici stands out for its ability to support the technological evolutions of our most demanding customers and to know how to adapt to the required changes.
This evolution has led our company to become the primary partner of all the main companies and industrial groups operating in the sector.
The range of products we can supply today is wide, from customized packaging to the insulating component (calibrated, milled and shaped) of sandwich walls for caravans and mobile homes, from disposable materials (formworks, ribs, fills, etc.) to insulating slabs by interspace or coat for building construction, from furnishing accessories (internal and external) to frames with various finishes.


The organizational structure, with qualified staff and well coordinated by the management staff, makes Espansi Tecnici a leading company in the sector. It is thanks to this organization that today we can boast a know-how first-rate technology that makes us a reliable point of reference for our customers and not only for them.
The equipment park is at the forefront and equipped with all the modern 'active quality control' systems, which is completed with an equipped laboratory, used for product checks, but also for tests and checks requested by our customers.


It is divided into two units with specific tasks and diversified by sectors of use of the product produced. The first deals with designing and developing all the block-shaped shapes; starting from the technical drawing sent by the Customer or by directly detecting the geometries (e.g. on a detail to be packaged) develops the necessary shapes, optimizes them in the block and executes the C.N programs. for the machines. The second is dedicated to semi-finished products (slabs); the project sent by the Customer proceeds with the optimization of the different cuts on the available plate formats, with the identification of the most effective and suitable processes and equipment, and the implementation of C.N. for processing. The cycle, starting from the virgin granule, consists in the expansion of the granule itself up to the desired density, in its seasoning in silos and in molding (in block or in slab) with the process defined as 'sintering', causing the surface cohesion of the expanded spheres through the action of steam (softening of the surface - expansion of the spheres and self-compression).


Block cutting occurs with “hot wire” machines, with the determination of the thickness managed by an inclination system of the frame (with interchangeable frames); the precision of the cut, on the machines with oscillating wire, guarantees tolerances of +/- 0.2mm. The calibrating machines are used to thicken Styrofoam slabs or to recover sheets out of tolerance EPS (conditioning them to lower thicknesses)


The drawing routing, with a hot wire machine, consists in interpolating the movements of the x / y axes according to the design that the technical office operators have transformed into a C.N. Tolerances are dependent on the overall size of the workpiece and the density required, as well as any 'burn' corrections provided upstream


The drawing routing is carried out on stacked slabs, and eventually milled if required, when an extreme tolerance on the thickness is required (not guaranteed by cutting to thickness pre-shaped blocks). It is possible to work with EPS and XPS panels, like any other meltable material (Polyester, PE foams, etc.)


We perform millings, both continuous and discontinuous, on slabs to be pantographed, or the entire process is carried out. including profile profiling (on controlled axis milling machines); in addition to EPS and XPS, different rigid materials and composite panels are processed there


We realize coupled panels, with or without frame, with different finishes (VTR, multilayers, Exalite, laminates, etc.) and cores (EPS, XPS and any other rigid insulating material required). The frames are made of wood or technical materials such as PET, PEC or PVC


Dimensional stability tests are performed with or without load), Tester for thermal conductivity, multi-test tester for checks on compressive strength, tensile strength, bending, fire reaction classification tester


All the waste produced by our processes is 100% recovered; in addition to this we collect all the polystyrene that is given to us by Clients, Companies and individuals, Companies for the assignment and selection of special waste.
The appropriately crushed waste returns to new life, inserted in our production cycles as secondary raw material, for the realization of:

  • Inert granules for lightened cement mixtures (100% regenerated)
  • Disposable formwork for concrete castings and lightened floors (100% regenerated if produced on ECO 100)
  • Packagings (20 - 40% regenerated + m.p. expanded virgin)
