The total chain is only as strong as its weakest link

This statement obviously applies to everything. All coating systems can be tested among the most spectacular conditions and with the highest marks in the tests, but always mention reasons why a coating system does not meet.

For each application, it is proposed a particular coating system. For example, it is natural that there is a coating system which is placed in an outdoor installation, on the coast, can now be brought to different demands than to a coating system which is used in a dry environment within and / or applied.

One-, two- or multi-layer systems are therefore always applicable. The obtained layer thickness and the applied coating are therefore always the protective factors of the underlying metal. With powder coating, it is no problem at all to inject 80 microns. For example, one operation on a flat surface. On these surfaces than normally occurs no corrosion.

The biggest problems always rise from the sharp edges and corners. When these sharp edges and corners are not rounded enough or deburred, this will always be the weakest link of the entire coating system.

On an edge or corner, which feels like a razor, is now one gets once insufficient film thickness, and thus this is insufficient protection. Especially in the current architecture, which is widespread perforated panels, these panels will have to meet certain conditions. All edges and corners should be rounded with a radius of at least 0.5 mm. The perforation holes should be as large as possible, most preferably not smaller than 10 mm. When the starting material meets these requirements, it will always have a two-layer coating system in order to achieve sufficient edge coverage and therefore protection. "Corrosion consciously construct" may not be sufficient attention. Though it is just to strengthen the weakest link.

Q-fin provides rounding and remove oxide skin

Q-Fin is a company that has perfect finishing and deburring machines. This Dutch manufacturer develops and builds machines for deburring, grinding and finishing of metal parts. The machines can also remove an oxide layer in one pass. Recently, Q-fin delivered the hundredth machine. In just three years! The first deburring machine     Q-fin brought to market was the Fierde 200 with two stations for finishing small parts up to was 200. Followed closely by Fierde 200 XXL, a three-station machine, which can deburr up to 200 millimetres wide. This machine can achieve a higher rate in the side break.

In the meantime Q-Fin is working hard to develop the Fierde 1200, for deburring large wide metal parts. This machine has four crossed and counter-rotating brushes, which oscillate back over the working width. The result is an optimal finish and a non-directional finish to the surface. In addition, there is an option for a vacuum or magnet belt so the machine is suitable for stainless steel, aluminium, steel and various plastics. Last year Q-Fin introduced the TopGrinder, a semi-automatic deburring machine, which you can find throughout Europe. And Q-Fin has a newest addition in their product range. In April the first test will be the introduction of the ‘Edge Rounder 1200’

 

This machine provides a guaranteed finish of R = 2 mm or larger on all edges. It draws the power of Q-fin: the customer has a problem and Q-fin finds a solution! www.q-fin.nl, the fastest solution of deburring, round edging and finishing.
