Our operations are quality certified according to the quality management system standard ISO 9001:2015 and the environmental system standard ISO 14001:2015.
Regular analysis of production processes and automatic dosing of chemical additives, as well as final testing of products, are an important part of a productive and professional surface treatment plant. Finished coatings must also be able to withstand the thermal shock test.
At Pinnoitus Helin we have pre-treatment processes for aluminium and aluminium alloys, copper and its alloys, steel and also hardened and stainless steel grades.

As with any coating, pre-treatment is important for the final result. In order to achieve perfect adhesion, the most important step is the activation of the cleaning and priming material. This allows the substrate to receive the desired coating. Adhesion is ensured by the metallic bond between the object and the coating, where the atoms share some of their electrons. It is therefore not possible to remove the coating from the bottom by mechanical means. The bond of the coating to the substrate also has an effect on the thermal and electrical conductivity of the piece. The soldering property may also become difficult or impossible without complete adhesion.
The methods of testing for adhesion are more precisely defined in the standard that we follow:
Electrodeposited and chemically deposited coatings – Review of methods available for testing adhesion (ISO 2819:1980)
