The assembling of two or more glass sheets with a laminated plastic film interposed between them, after being adequately handled in autoclave, is called STRATIFIED GLASS. Of large use, and more and more requested by the market by virtue of the more restrictive norms in subjects like stoutness and security, are tempered glass, tempered/ thoughened, both flat and curved, up to break-through proof and bullet-proof glasses. Therefore, it can be easily understood how the kind of assembling, of laminated plastic (PVB) and above all the polymerization treatment inside the autoclave are of essential importance to obtain a product of good quality. In fact, the use of ITALMATIC autoclaves allows to obtain the desired quality of the product. The reliability and the precision of the cycles in autoclave allow to reach and keep high quality standards of the product.
Autoclaves for production of photovoltaic panels
Italmatic Autoclaves for the production of photovoltaic panels are hyperbaric chambers where temperature, pressure and vacuum are controlled. The photovoltaic modules are kept in single bags and loaded horizontally on the corresponding tray trolleys. The control system, developed on purpose for these applications, allows the running by step of all process parameters, assuring a high quality of the final product, which is always certified by the producer.
Autoclaves for composite materials
In the last years we have seen the evolution of new materials, with excellent mechanical and physical features. The mechanical resistance, together with the lightness of COMPOSITE MATERIALS, are finding more and more applications. We call composite material the product obtained from the polymerization of carbon fibers and resins, adequately prepared and shaped overlapping coats of fibers and resin on moulds or cores. The polymerization of resins can occur in heated moulds or in vacuum with controlled temperature, but if we wish to obtain better results, it will be necessary to polymerize our product in autoclave, keeping it in sealed vacuum suitable envelopes to eliminate air infiltrations and submitting it to an outside pressure to improve its compactness. In fact, the quality of the product is obtained inside the autoclave reaching an increase of mechanical features up to 20-30% compared to other methods of polymerization, which do not foresee the outside pressurization of the product. Recently, at the success of the thermoplastic resins and materials, we assisted at a further evolution of the process techniques. Italmatic autoclaves followed these innovations at par and assure safety, reliability, precision and repeatability of cycles in time.
Autoclaves to rubberize rollers
To obtain rubberized products of high quality it is necessary to cure rubber directly on the metal support to be coated. Therefore, after coating the product with green rubber, it is necessary to cure it; if there are small pieces and large quantities, moulds and presses, where to put the manufactures or directly inject rubber, can be used; but if there are pieces with important sizes and limited quantities, the alternative is curing in autoclave, where pressure and temperature are controlled and there is no need of containing moulds. Clearly, if special surface finishings are required, these must be carried out after curing. Pressure and temperature can be planned according to the rubber compound that was used for coating and according to the metal mass, which the piece to be rubberized is built with. In this field ITALMATIC is in the van both for technology and specific knowledge, as it has been producing for more than 20 years rollers and items coated with the most various compounds. This direct experience allowed us to develop new solutions for installations and curing cycles, testing the different possibilities to exalt at the most the features of our rubber coatings.

Autoclaves for E.M. tyres retreading
OTR autoclaves are mainly manufactured for E.M. and agricultural tyres retreading and repair, but they can also be used for truck tyres. Heating systems:A. With direct steam.B. With air and steam mix.C. With hot air circulation with steam coil, or heating element, or combined with both.They can be equipped with a central support beam combined with monorail for truck tyres, or with upper monorail for an optimal use in case of OTR retreading with “precured” system. OTR autoclaves are fitted with modern equipments for pressure and temperature control. They are completely insulated and they have very low heat loss. They are equipped with hydraulic system to close the door and with manual, automatic and emergency safety systems.
Autoclaves for impregnation
Autoclaves are specifically manufactured to warrant a perfect impregnation in vacuum by means of resins, compounds, etc. This application is especially known in mechanical, electrical, electronic industries, in the ones working wood, in foundries and in the “Marble/Granite” field. In electrical and electromechanical industries in general, the impregnation procedure increases the capacity of dielectric resistance of the components and also their insulation resistance, warranting the impossibility of introduction and deposit of outside impurities in the porosities of the materials under treatment. In the wood industry, this treatment allows the absolute protection of the material destined to the use in buildings in general, where long efficiency and life are requested in outside climatic conditions particularly severe. In the mechanical industry and in foundries, impregnation warrants insulation to the components in aluminium, brass, iron, magnesium, zinc, etc., to avoid absolutely the deposit of impurities that would cause the refusal of the component by the production lines. In the “Marble/Granite” field, the autoclave is used to renew inside breakages/cracks of blocks or sheets of valuable granites or marbles, by the application of special resins in vacuum and pressure conditions. Autoclaves can be manufactured with every size and can be also supplied complete with centrifuge and washing tanks. Moreover, installations in line or at circular island can be carried out, in accordance with the specific requests of the Customer.
Autoclaves for stator bars treatment
The autoclave is destined to be used in the plant for the treatment of Roebel half coils and stator coils, with insulation of type Resin- Rich. It is used in the process of insulation of stator elements of electric machines, using the COMPOUND technological cycle. In the process a mixture of bitumen named Compound is used. The compound, kept at a liquid state and at a temperature of approx. 170°C, is used as an energy vector to heat stator bars contained in the tank inside the autoclave. The heating of the autoclave and of its content is necessary to generate the polymerization of the insulating resins deposited, at a gel state, on tapes that are wrapped around the bars to be insulated.
