LASER CLEANING - MOULD REMOVAL
To meet these regulations, it is necessary to clean the moulds in an environmentally friendly way. Sand-blasting or the use of chemical solvents is a no-go. Laser cleaning is an excellent solution because it is clean and very easy to integrate in-line.
Speed is the decisive factor when it comes to rubber mould cleaning. For example, cleaning a tire mould (for a passenger car) takes eight hours of machine down-time and the same amount of manual labour time if done in the traditional way (blasting or chemical cleaning). Laser cleaning systems can clean 2m² per hour, a drastical improvement.
A lot of aluminium moulds are used in the rubber industry. Laser cleaning makes sure the base material is not affected by the technology, surpassing sand-blasting.
On top of that, laser cleaning technology is able to clean thicker and sturdier contamination, which is very difficult using the traditional methods.
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.

- There shouldn’t be any increase in volume of for example bottles. Because of this the base material cannot be affected.
- Closing edges have to be preserved to make sure no burrs are introduced.
- A lot of small holes can be found in glass moulds to make sure air can get out. Laser cleaning ensures good cleaning of these holes and of course no residues are left behind.
Using chemicals can be very dangerous because the base material might be harmed by the toxic chemicals. Apart from that, the chemical waste would be outrageous. Because of the large surfaces that have to be cleaned, high speeds are demanded.
- High Power systems will deliver the speed that is demanded.
