In many areas of application, vacuum coating technologies continue to replace traditional methods such as chrome electroplating. The flexibility of this technique enables all types of materials, without distinction of shape, structure and size to be coated. This process gives technical as well as ornamental objects a very shiny, reflective, metallic look which can be in various colours. In addition to obtaining high surface resistance, products gain a decorative look lasting over time.

The main existing applications for metallization are as follows:

  • reflectors and bezels, interior-lights, solar-concentrators
  • cosmetic packaging
  • EMI/RFI masks
  • design and lifestyle products
  • ornamental and decorative articles
  • car interiors and exteriors
  • toy parts
  • fashion and costume jewellery accessories
  • Christmas tree decorations, buttons, frames, push buttons, handles, plates
  • various accessories such as knobs, moulding, dashboards, doorhandles (only to mention a few…)

Metallization - The Concept

KOLZER metallization equipment are available in both horizontal and vertical versions: manufactured using the best materials and components available on the world market, both have robust steel process chambers which come in different sizes.


Characteristics and advantages:

  • Low temperature ecological process
  • Vacuum pump system efficiency and high productivity
  • Simple visual interface for the operator
  • Automated work cycle
  • Process software with more than 60 years of know-how in the database to pilot the completion of the operation according to the application in use.


The loading system:

The materials to be coated are fixed onto piece holders also called ”satellites”, in turn ,these are fixed onto the loading/unloading system, also called “planetary system”.

During the coating process, the satellites rotate around the source of evaporation and on their own axis, to “metallize” even complex surfaces
 uniformly; the vacuum ensures the ideal conditions needed for a perfectly uniform and compact coating.
 

The operative phase:

  • The pieces are fixed onto the satellites, which in turn are fixed onto the loading system.
  • After closure of the coating chamber the automatic cycle starts.
  • The metallization process starts when the vacuum reaches the optimal value.
  • At the end of the process the system brings back atmospheric pressure to the chamber.
  • The plant is ready to metallize the next load, already set up on the second loading system.

Metallization - The Process

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 frequently used method of industrial metallization.

After the pre plasma treatment in the process chamber, deposition onto moulded shiny “mirror-like” plastic materials requires a coat of preparation that levels and isolates, increasing adhesion of the subsequent metal layers and trasparent finishing. The base coat has three different functions which are fundamental in order to obtain the best process results:

  • aesthetics
  • isolation
  • 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 are 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 increasing.

This process is used with multistage processes 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 metals

This process is used in cycles which metallize for aesthetic purposes. Today, transparent finishing is carried out mainly with 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 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.

A complete installation for metallization in the decorative/functional field consisting of a metallizer, a cabin for varnishing parts, an 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 production, as well as providing skilled and technical post-sales assistance that is world renowned.

KOLZER is your partner for demanding surface finishing.

 

Metallization - The Control

A PC is used to automatize all the process phases (emptying, plasma cleaning, metallization and final protective coating).

A PC display supervises all the operative phases giving instant reports, data on the system and on the cycle condition, 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, are easy to use and have totally automatic process control systems that eliminate operator error.

Regardless of the technologies of the different fields, with KOLZER the client receives everything from a sole supplier to optimal individual solutions, advice, planning, training and a made to measure plant for client specific production. Profitability and quality for the client are of prime importance.
