Laser Hardening Technologies: Precision And Innovation In Mold Treatment.pdf

The Laser Application Center specializes in laser technologies for machine creation, offering services like laser hardening of molds and tools. They provide two methods: contour (1 spot) and surface (overlapping), with a robot cell capable of processing parts up to 2000 x 2000 mm and 3000 kg using CAM software and customer-provided 3D models. Laser hardening ensures constant temperature via an IR pyrometer, suitable for materials like cast iron, structural steels, and various tool steels, achieving surface hardness of 55-60 HRc with a depth up to 1 mm, requiring at least 0.3% carbon content.

Advantages include low temperature deformations, on-line process control, high speed, minimal further processing needs, no surface cracks, low oxidation, environmental friendliness, energy efficiency, and easy automation. The center also offers laser powder cladding for refurbishing surfaces, increasing part life, creating functional coatings, and enhancing resistance of stressed parts using nickel, cobalt, or iron-based powders.

Laser cutting services include 2D cutting of structural and non-ferrous metals up to 4 mm thickness and 800 x 600 mm size. Laser welding joins metal parts without additional material in pulsed or continuous mode, with high speed, minimal deformation, narrow heat affected area, and precise weld quality. The center also provides laser welding for plastics using transparent materials and laser engraving on metal surfaces up to 110 x 110 mm.

A metallographic laboratory equipped with a hardness tester and microscopes evaluates technology results. Hardness depth is assessed post-hardening, ensuring high-quality outcomes. The Laser Application Center offers comprehensive solutions for enhancing machine part performance through advanced laser technologies.
