  • Simplicity of use, no consumables

The French company Laselec is specialized in the manufacturing of laser cleaning and cabling systems used in industrial sectors such as aeronautics, space, railways, automobile and polymers. Now the company has introduced the MLC 500, a quick and effective cleaning system for rubber and polymer injection and compression moulds.

Laser provides alternative to ultrasonic baths and blasting

Until now, two systems have been commonly used to clean moulds: ultrasonic baths and blasting with dry ice, peach stones, sand, or other materials. The ultrasonic cleaning method can be considered as expensive, polluting and time consuming. Blast cleaning is very noisy with high costs for difficult-to-store consumables. The MLC 500 laser cleaning system eliminates these drawbacks: it provides a fast, safe and ecological solution with a quick return on investment, according to the company.

Fast-moving laser beams reduce cleaning times

The MLC 500 laser can clean horizontal, vertical or inclined surfaces, and complex shapes. The laser beams can move at 50 mm per second, thus reducing cleaning times. In addition, moulds can be cleaned while still hot. The cleaning cycle time is cut by 75%, or even more in certain cases.

Simplicity of use, no consumables

The machine’s simplicity lies in its automatic programming: MLC 500 automatically programs the laser’s trajectory from the mould’s graphic data DXF file. The machine works with a standard electrical outlet and requires no consumables. The process is non-abrasive, non-polluting, and requires no additives and no specific protection. Residue removed by the laser is vacuumed up and filtered through an activated carbon filter that also removes any odours.
