The
term metallization generically means sublimation and condensation
(deposition) onto a
substrate of a thin metal film at a low pressure of about
10-4 mbar. Low pressure (vacuum) enables the metal molecules
to move from the source of evaporation to the surface to be
coated avoiding contact with air and other gas particles.
Sublimation and deposition of aluminium onto a product is
the most used method of industrial
metallization.
After the pre plasma treatment in the process chamber, deposition
onto moulded shiny “mirror- like” plastic material
takes place directly. As a rule, all other materials require
a coat of preparation that levels and isolates, increasing
adhesion of the subsequent metal layers and transparent finishing.
The base coat has three different functions which are fundamental
in order to obtain the best process results:
a) aesthetics
b) isolation
c) interface for adhesion of the subsequent layers.
The deposition of aluminium and other metals has an aesthetic
and functional role. An estimated 60% of metallization applications
is fundamentally for aesthetic purposes , but with the progressive
change of chrome electroplating coating processes, both expensive
and highly dangerous for the environment, functional type
applications are on the increase.
- This process is used with multistage cycles which have
been set up for the cycles which metallize vehicle headlights
and parabolas for all types of reflectors:
- plasma
- metallization using aluminium
- plasma polymerization
(in a single process)
- This process is used in electronics and for electromagnetic
insulation:
- deposition of many layers of different metal.
- This process is used in cycles which metallize for aesthetic
purposes. Today, transparent finishing is carried out mainly
on varnishing products since their shiny and glass-like
look enhances the bright effect and image definition reflected
by the deposited metal coating giving extraordinary, both
aesthetic and functional, results. The function of the finishing
coat, also coloured, is very important too as it protects
the deposited metal against wear and from chemical corrosion
(perfume, essence, sweat etc) and completes a coating cycle
made up of multi layers that cohere to each other well.

oven to dry the varnish, compressed air and water cooling systems.
In addition to all the machines KOLZER supplies the materials and accessories needed for the work,
as well as providing skilled and technical post-sales assistance
that is well known all over the world.
KOLZER is your partner for demanding surfaces
CONTROL
Automatic
control:
A PLC is used to automize all the process phases (emptying,
plasma cleaning, metallization
and final protective coating).
A PC displays and supervises all the operative phases giving
instant reports and data on the system and on the condition
of the cycle, informing and guiding the operator through the
process. Printer, keyboard, mouse, LCD video, lan card and
modem for on-line assistance are provided.
Today the experience matured by KOLZER enables production of plants which have minimum
process times, easy to use and totally automatic process control
systems that eliminate operator errors.
Regardless of the technologies of the different fields, with KOLZER the client receives
everything from a sole supplier, from optimal individual solutions,
to advice, planning and adequate training up to made to measure
plant technologies. Profitability and quality for the client
are of prime importance .
