We have a bystronic bysprint 3015 6kw fiber laser cutting machine at our main facility in petersburg which can cut sheet sizes up to 5 x 10 1500 x 3000 mm.
Powder coating laser cut edges.
An ongoing discussion from 1999 through 2015.
However one of the problems inherent to laser cutting is the blue oxide edge it leaves on carbon steel.
Wayne duguay houston.
Laser cut material edges are typically high quality but there will be a minor burr on the bottom side of the cut.
Today the 107 5 by 59 1 by 60 2 in.
When chipping was first seen on powder coated parts many people thought it was because the edge was so sharp.
The chipping reject.
To avoid paint chips on the finished part edge remove the laser scale prior to finishing.
The only way around this would be to put a chamfer onto all sharp edges this is a massive cost and process change.
We have started manufacturing parts using a laser.
Laser cutting is a thermal process and.
Laser cutting machines provide manufacturers with an effective means to cut blanks of all shapes with burr free edges in a matter of seconds.
Powder coatings don t like to adhere to this oxidized surface.
Nitrogen purity levels play a large role in edge and part quality.
The danger of powder coating laser cut edges.
The chipping you refer to with powder coating is a loss of adhesion due to little if any pretreatment on the laser cut edge.
Machine sits in the middle of four laser cutting machines.
This system will not remove the carbon.
Acid pickling is one method that coaters can use to prepare their laser cut parts prior to finishing them.
You can improve a fiber laser blanking s cut edge by optimizing the assist gases and nozzle technologies.
As steel is cut with a laser a very thin hard oxide is formed on the sharp edge.
The absence of oxidation improves downstream processes such as powder coating and welding because better adhesion and weldability can be achieved.
Nope this is a first time question.
The parts are laser cut and powder coated.
News machining fabrication laser cutting powder coating jobs contact laser cutting.
The issue with paint adhesion in this area is due to the formation of heat scale on the edge of the steel.
The parts have a carbon build on the edges our present system is an alkaline rinse phosphate rinse seal.
Pretreating laser cut material for powder coating.
When oxide scale created by laser cutting is painted over the part being finished is susceptible to adhesion failures.
After reading many different views on this and my own opinion is that paint will not adhere fully to a sharp edge.
