Laser Engraving Applications

Laser engraving beyond a doubt is the most flexible and simple means of direct part identification or serialization available today. The ability to mark or deep engrave on a host of different materials by simply changing various parameters, offers an unsurpassed control, flexibility, quality and speed versus other types of marking methods. Z-Tech Advanced Technologies fiber pumped, solid state N:d YAG diode, Yv04 diode, and lamp pumped laser engraving systems are available with an average power from 10W-100W with or without CDRH class 1 enclosures, motion integrated controls, or OEM kits.

Several factors are employed to produce certain look on a finished part such as power output, number of passes, number of pulses and, frequency.

Surface mark: It is ideal when marking on coatings without penetrating through, such as chrome, nickel, gold, and silver etc.
Surface coloring: Most common when marking on titanium or stainless steel.
Deep engraving: Utilizing a high power laser this process vaporizes a material to engrave into the base metal. Most common in plastic injection molds, Jewelry making, and stamping dies.
Ablation: Removing surface treatments (i.e. plating, and coatings of paint) to create translucent back round without damaging the base material, widely used in backlit material processing such as backlit buttons.

Z-Tech Advanced Technologies’ entire laser marking systems are capable of marking in 3D, 2D, data matrix codes, bitmap photos, serialization, graphics, OCR codes, security codes, lot codes etc…
