Thanks to the technology matured over the years, Antonini annealing lehrs guaranty low consumption levels and maximum efficiency. Furthermore, by using high-quality materials and components, the lehrs ensure a long service life with extremely limited maintenance requirements. An automatic control system guarantees uniform and stable heating temperatures inside the annealing lehr.
To cure decorations, where the uniformity and accuracy of the temperature and the repeatability of the process are fundamental, ANTONINI proposes its own Decorating Lehrs where these features are fully attended. A Decorating Lehr can be considered as the extension of an Annealing Lehr, to which some modules are added at the beginning to heat-up and fire the decorations. The consolidated quality of Annealing Lehrs allowed us to apply the same high technology to these modules which are extremely important as they constitute the innovative items heating and paint fumes extraction systems. Both innovations guarantee an accurate thermal process and a clean fumes evacuation ducts. The Decorating lehrs are composed of: • A charge table suited to hand or automatic items belt loading. • An exhaust hood to eliminate the fumes produced by decorations. • A hand-lift or motorised inlet door. • A series of high power heating modules (usually 2, 3 or more), for a heating speed that goes from smooth to ultra-rapid (suited to special decors), based on Customer requirements. • A system that extracts and exhausts the fumes. • A temperature control and measurement system. • A “bi-component” insulation, specifically and carefully designed to guaranty absolute stability over time. • A tunnel section and an uncovered table exactly like a classic annealing Lehr (see the section regarding Annealing Lehrs).
The ANTONINI product range includes these Kilns that are a part of the auxiliary equipment needed and sometimes indispensable for glass production. In particular, these Kilns are used to: • Pre-heat moulds; • Perform specific heat treatments on instruments such as delivery, moulds and the like.
There are two different types: Stand-alone. These are small chambers that are heated using standard systems (direct or indirect gas, electrical, other), which are, however, in the majority of cases, fitted with mechanical handling systems, such as extractable, single or multi-stage trolleys, single or double doors, etc. In addition to the standard versions (see photo), there are custom versions, of which the photos are merely an example of the designs possible based on Customer requirements. These kilns are manufactured using components that are almost identical to or interchangeable with those used in the annealing lehrs, in order to reduce spare parts needs to a minimum.
Built-in. These are convenient “pockets” created in the side walls of the first zones of an Annealing Lehr (see photo). The chamber may be accessed through high-insulated doors fitted on hinges with individual latches. Where it is necessary or possible to adopt this system, the resulting reduction in terms of energy consumption and space requirements is evident.
ANTONINI SRL, founded in Empoli (FI) in 1946 by Fosco Antonini, was born as a small, artisan business that manufactured tools and small equipment for the hand and semi-automatic made glass articles. To meet the increasing demands of local glassworks plants, ANTONINI subsequently specialized its production, manufacturing annealing and decorating lehrs for hollow glass, gaining prestige at both local and national level.
A rapid expansion abroad followed, where ANTONINI demonstrated its high competitiveness, affirming itself in the markets of all 5 continents. Today, ANTONINI is among the world leaders in its market and boasts the presence of over 1300 installations in 80 Countries the world over.
