LaserStar Technologies will showcase its 7700 series micro-welding laser system for plastic injection mold, tool and die maintenance and repair applications. According to the company, the laser system can lay a bead as small as 0.0025" (0.05 mm); repair slots, pockets, radius contours and angles; repair polished, textured and engraved surfaces; repair thin walls with little or no warping; and repair parting line edges and heat-sensitive areas. Alloys include tool steel, aluminum, copper, titanium and powdered metals. The system is said to reduce the amount of handwork needed before polishing and to virtually eliminate sink lines.
