In the anodising process, one step in especially takes a lot of time: hot sealing. But this no longer has to be the case. With the FastsealAL process from Alufinish, you can save a lot of time in the anodising process. Nowadays 2 min./µm are already possible by using suitable ...
When aluminium reacts with its environment, this often causes pre-corrosion. Different, mostly barely visible changes on the surface of the aluminium are the result. But what are the effects of pre-corrosion? If pre-corrosion occurs on the material, this often leads to unsaleable goods. This is because the pre-corrosion on the ...
The Tin – ColorAL process is based on tin (II) salts and is known for the variety of colours produced from C31 (champagne colours) to C35 (black). The tin – ColorAL process is based – as the name suggests – on tin(II) salts and is applied by means of alternating ...
For Alufinish, digital microscopes are an important tool in our daily work. With our new digital microscope we have many new possibilities to support our customers in the evaluation of error patterns. In the latest video we show you the advantages of the new digital microscope and which error patterns ...
The ENVIROX NR system (products Alficoat 748 and Alficoat 748/3) was already developed at the end of the 90s, then tested and approved for applications on aluminium surfaces by renowned quality communities (Qualicoat, GSB International). It was even subjected to the 10-year outdoor weathering test specified by GSB International in Hoek ...
Aluminium also looks very good coloured. The Alumino series from Alufinish is based on organic colours and is therefore especially easy to embed in the anodised layer. But how does this dyeing process work? In this video, Mr. Sondermann explains to you how aluminium is correctly coloured with Alumino from ...
Alfiseal 942 – Easy – Seal AL Process You need a hot sealing additive that will achieve clean, dry-to-handle surfaces with “anti-fingerprint” properties? Perhaps you are looking for an additive that meets all the Qualanod requirements and ensures the long-term stability of your sealing bath? Or maybe you need a ...
In the treatment process of aluminium – for example in anodising – a clean surface is very important. The following question often comes up: how can we check if an aluminium surface is free of grease and oil when it comes out of the cleaning bath? Certainly, this can be ...
Environmental protection and the search for more compatible processes have also had a strong influence on pre-treatment. In the past, chromium VI compounds were used to provide good corrosion protection and, due to the chemical composition of these baths (chromium(VI), conductivity values of about 8000 µS/cm and a strongly acidic ...
The pre-treatment of aluminium surfaces in alkaline E6 long-term pickling processes produces fine-matt, very decorative surfaces. However, this appearance is negatively affected by the accumulation of certain contaminants to such an extent that the anodised product is often not saleable and has to be reworked. In addition to the known ...
