SMAC PRESENTS: MULTIGLAZE SYSTEM
04.12.2017
A wide range of products can be obtained from glazing and decoration techniques for clay roof tile and faces bricks surfaces. The decoration methods listed here below , produced and development by Smac, are utilised world wide from many years in the decoration of clay roof tiles and bricks surfaces:
° uniform coating with rotary atomisation;
° spraying;
° application of powders and other granulates.
In the last year in this decoration sector, the trend is directed to the growing use of brilliant glazes due to the improvements in North Africa and Middle East markets. It’s also increasing the attention towards the most possible automation of plants, with designs of plants managed automatically on all their parts avoiding material and personnel waste
Today, we will present you the last innovation for the uniform coating with rotary atomisation of roof tiles and accessories, called “MULTIGLAZE SYSTEM”.
The market know that the most used method for the uniform coating of roof tiles surfaces is the rotary atomisation with discs booths. Rotary diffusion of the glaze/engobe occurs via high speed rotation of disc packs of different diameters and design, equipped with waved or grooved discs. The rotary units are direct loaded. The rotation can be clockwise or anticlockwise , to get more control on glaze stream, and it is selected by the suitable selector place on command board. The discs units are fed via perforated glaze/engobe pipes, connected to a rotary pump.
This method is spreading quickly and is recognised as the best method for its uniform glaze/engobe coating, both for standard pieces and the ever increasing trend for special shape/size pieces.
SMAC produces for this type of application a compact machines, where the discs remains within the machinery and operation is external. The machine uses hollow rotor motors of last generation, completely designed by SMAC, which guarantee high quality and high duration standards. In order to prevent non-glazed areas, these booths have numerous possible adjustments both for inclination both of the disc and the entire metal internal structure (superior and lateral towers), over and above the already cited possibility of disc rotation in both directions.
With the aim of meeting the ever-increasing number of clay special pieces/accessories and to facilitate the uniform application of brilliant glaze SMAC in the last year developed the new system named MULTIGLAZE.
This system is now the best offer of the market for the uniform glazing with liquid in the field of clay roof tiles and accessories.
MULTIGLAZE is a glazing station composed by a support frame, independent conveyor, automatic glaze/engobe feeding with automatic recycle, automatic washing device with separate waste waters recovery. The glaze/engobe nebulisation is done through 3 upper rotary units and up to a maximum of 6 lateral rotary units in order to obtain the best application on piece’ surfaces
All the rotary units are adjustable in height, inclination and spray angle. The large number of discs packs and the large number of possible settings, allows a better application of the glaze on the pieces since each discs pack will apply smaller quantities but with more nebulisation. Furthermore thanks to the application units placing the perfect coating of the entire production range of special pieces and accessories will be guaranteed.
The system is completely automatic and needs minimal maintenances and controls during its functioning . The independent transport system allows to avoid any loss of glaze/engobe and facilitates the installation into the production line, Colour feeding is done by pneumatic pump complete of pulsations compensation system which allows the glaze constant flow and consequently an optimal application on the pieces.
Besides the new automatic cleaning device allows to obtain in a few minutes a very good washing of all the internal parts of the machine with the automatic recovery of glaze and the deviation of dirty water. This allows rapid change of production and colours with very minimal worker intervention.
With this application method the error possibility is very low and moreover this system is not subjected to stops for adjustments or maintenances. With constant glaze/engobe quality parameters and constant line speed, the applied weight results always uniform. The whole system is controlled by an electric command board with PLC and inverter which allows the programming and the rescue of production parameters into memorized receipt and it can be also integrated into Multiline software for the management of the entire engobing/decorating/production line.

NEWS FROM SMAC FOR DIGITAL GLAZING LINES AND LARGE-FORMAT TILES PRODUCTION
08.09.2017
TILES COOLER DEVICE KRYO
SMAC, usually at the forefront in research and development of machines and accessories for tiles glazing and decoration lines, presents KRYO as tiles cooler device to be placed in the glazing line to cut down tiles temperature and moisture before digital decoration with inkjet machines.
CLIMATIZED INKS SHAKER DINK
Today, the new printing technologies in the ceramic field require more and more indispensable expedients and devices to get this process more stable and as repetitive as possible. Mostly affected are the new ceramic inks with pigment suspensions reaching particle size distributions even lower than one micron.
INK STIRRER TAGADA
TAGADA is a device for automatic agitation of the tank ink to be placed directly in the decoration line near the inkjet digital printer. TAGADA is an economic unit, easy to use and designed to shake pigmented ceramic inks because they have the tendency to deposit during a long storage periode.
D-GLAZE DEVICE FOR GLAZE DENSITY CONTROL
To have constancy in colour tonalities, it is very important to have always under control the base glaze applied before digital decoration. Until now, this was done with empirical methods, often based solely on experience and manual skills of the glazing line staff.
TITAN: AIRLESS GLAZING SYSTEM FOR LARGE-FORMAT TILES
The ceramic tiles production has recently embarked on a road leading to more and more large-format production, either by traditional pressing or through plants of new generation with continuous compactionsystems. Officine SMAC, being always attentive to new customer requirements, has designed the innovative airless glazing system TITAN dedicated to these new ceramic slabs.

KRYO TECHNOLOGY FROM SMAC ENJOYS NEW MARKET SUCCESS
06.09.2017
Demand for technology in the field of digital lines and related accessories continues. Officine Smac SpA again confirms its leadership thanks to the innovative and patented tile cooling system Kryo, which day after day collects confirmations from the market.
KALE – Turkey
The Turkish Group strengthens its partnership with the company Smac from Fiorano Modenese: 22 the units installed on its production lines. This further confirmation is a great matter of pride for Smac that sees growing more and more customers confidence in the technologies and solutions to complement the new digital decoration lines.
Coop Imola - Italy
New confirmations also for Cooperativa Ceramica d'Imola, since 1874 historic brand of Italian manufacturing, with today's production of about 20 million / mq annually. Up to 5 units are installed, confirming Smac's reliability for solving problems of high temperatures and emission of steam during digital printing. Thanks to Kryo's technology, these obstacles have been overcome, allowing production increases and significant improvements in the quality of the final print, even on high-thickness products and large size slabs.
Crossville Ceramics - US
Crossville Ceramics, one of the historical overseas production companies, relies on Kryo's Officine Smac technology. There are already two Kryo machines installed on digital production lines.
This new installation represents a further confirmation of how Kryo's technology has now become a reference point not only in the Italian ceramic district but all over the world production.
Villeroy & Boch – Germany
Even the historic German brand Villeroy & Boch has confirmed the confidence in Smac's technology and today the machines in production are three, thanks to the latest installation of July.
