Latigloss and Kelon: structural
and good appearance thermoplastics as winning
solutions in home furnishing
For over 60 years Serrature
Meroni, a well known Italian company with large
presence also in the international markets, has
produced locks and closing systems both mechanical
and electronics, for use in a wide range of sectors
that include not only doors and furniture, but
also utilities, vending machines and special applications.
In 1973 the real best-seller of Meroni
Serrature made its appearance in the market under
the brand name PremiApri (literally PressOpen),
an exclusive patent that won several recognitions
in the Industrial Design sector.
the different models of PremiApri locks, today
a new solution is created and named "Combina".
The Combina solution, in order to keep up with
the times, is created by using special thermoplastic
materials, representing an intelligent balance
of tradition and technology.
LATI has worked together with the idea
of Serrature Meroni supplying its engineering
thermoplastics suitable for the design requirements
and the technical aspects of the project.
The body, actually the structural frame of the
knob lock, is available in metal and in LATI
metal version is realised in die-cast Zamak (an
alloy of Zinc, Aluminium and Magnesium
that gives the acronym too), one of the most proved
and reliable materials used in architectural design
and furniture industry.
This material, stiff and solid, provides not only
the requested mechanical properties, but also
the best surface quality.
The thermoplastic version is made by mean of the
injection molding technique, using a new and innovative
special resin developed and researched by LATI
and named "LATIGLOSS".
Also studied for the door hardware and furniture
industry, this polymer is a compound of nylon
66 reinforced with the 50% of glass fiber, blended
with special additives giving a superb surface
Indeed one of typical limits of glass fiber reinforced
thermoplastics is the finishing quality: the glass
fiber normally appears onto external surface,
causing uneven colour effect or, in the worst
case, visible flow lines.
To avoid this behaviour, the mould engineers have
to set high cycle times or time-consuming pre-heat
On the contrary Latigloss, without moulding cycle
time increase, provides at the same time high-end
mechanical properties (similar to metal) and a
top-class surface smoothness and brilliance.
wide upper cap too is made of a thermoplastic
resin produced by LATI, called "KELON".
Kelon (an acronym of Keramic
+ Nylon) is a nylon 6 based polymer,
blended with special ceramic spheres and then
The presence of these micro-spheres and the
process, giveto the material high values of
resilience (the ability to maintain the rigid
shape and theelastic response too), in conjunction
with a uniform "high gloss" surface
All the most known post-finishing operations
are allowed with this nylon based material,
giving to final customers a wide variety of
colours and effects choice.
In simple words, the "Combina" lock
drives with the same smoothness the way of tradition,
by choosing a worldwide known metal alloy, and
technology, by a selected combination of "intelligent
The "Combina" is today presented
in all typical functions, and suitable for several
applications: passageways, bathrooms, entrances
and offices, classrooms and hotel rooms.
