EXPERIENCE ON THERMAL BREAK, FOAMED AND SMALL CAVITY PROFILES
NECE boasts decades of experience in the field of anodizing of aluminum profiles for windows and doors, with a wide range of colors.
Following the numerous tests carried out, in this long period of time, he was able to ascertain that some of the thermal break profiles, including the innovative systems, are not very suitable to be anodized with Inorganic Colors, as it is not possible to obtain perfection on the non-visible surface (internal part of the profile).
The limit found in this process consists in a slight discoloration near the coupling, between aluminum and polyethylene, due to the geometry of the profile itself, where it is not possible to obtain a perfect color.
By Inorganic Colors we mean all NECE swatches coded with 2B, 3B, 4B, 5B, 6B champagne, 2B LP, 3B LP, 6B LP, champagne LP, while those coded with letter A are Electrocoloring, therefore not subject to this problem. , including silver and steel.
NECE Anodizing therefore recommends that the customer check the possible problems that the thermal break profiles may present, before confirming the order, in order to avoid unpleasant inconveniences when the processing is completed.
The evolution and the market demand for increasingly high-performance thermal and acoustic performance has forced the introduction, in the world of windows and doors, of elements that often cause problems in the anodizing process.
THERMAL BREACK, FOAMED and/or SMALL CAVITIES PROFILES (blocked by shavings) are NOT guaranteed for the anodizing process.
The ARC CHIMICO, SD, and SI finishes are NOT technically feasible.
It is the customer’s responsibility to send any drawings to carry out detailed technical analyses.
NECE’s experience and cutting-edge technology has allowed brushed finishes such as:
- ARS
- LP
- SISAL
- NV
- VB
- SABBIATO
also NOT guaranteed, give a significantly better result and to be usable.
NECE always recommends checking and cleaning by the end user as some treatment residue may remain.
No complaints are accepted for these profiles.
