On the left side of the picture you can see a lower porosity as a result of good surface cleaning. The less porosity in a weld, the less chance it will break over time.
High speeds can be reached when preparing and cleaning the welds on aluminium, which makes laser cleaning a very effective solution.
STAINLESS STEEL CLEANING
A lot of plastic moulds have a specific structure that may not be damaged when cleaning. Traditional cleaning methods like sand-blasting cannot guarantee this preservation, laser cleaning can.
On top of that, a lot of moulds are designed with a high gloss finish to transfer to the final product. Laser cleaning makes sure this high gloss is not affected by the cleaning.
