The use of Lasers for shading checking is anything but an especially new method as it has been perceived for more than 10 years. This strategy was initially distinguished as a reasonable procedure for use on make metal work and adornments. Be that as it may, the procedure has had next to no business sway in the mediating years.
There is currently a more noteworthy enthusiasm for this procedure as makers of customer merchandise are searching for new strategies and completions to give item separation. This application understanding glances at an assortment of materials that are shading mark-capable including titanium and tempered steel, and investigates the advantages and boundaries of the Pulsed Fiber Laser corresponding to this application zone.
Introduction
There are a wide scope of materials that are known to be shading mark-capable including: hardened steel, titanium, chrome plate and progress metals. The particular material evaluations and surface completions can affect the checking procedure as can the thickness of the material.
Brushed surfaces are more hard to check with a reliable shading mark because of the greatness of the unpleasantness as far as top to trough being essentially bigger than the profundity of oxides being produced. In these cases the grain of the material can even now be found in the imprint. Cleaned surfaces have been seen as unmistakably more reliable regarding shading. For this situation the grain of the imprint is more lined up with the checking heading. Another important consideration for stain marking is the pulse frequency of the laser. Peak power of each focused laser pulse decreases as pulse frequency increases. Since the goal of stain marking is to heat the surface rather than vaporize it, lower peak powers and higher pulse frequencies tend to generate more heat on the surface of the part rather than engrave into it.
Benefits of Laser Marking
Lasers offer some unmistakable points of interest over elective innovations as they give a non-contact, predictable stamping process that produces permanent imprints. Checking frameworks are anything but difficult to work with no tooling prerequisites. The entirety of the imprints are programming customized and commonly made with CNC controlled scanner reflects that are fit for line checking speeds up to 6m/s, which likens to almost 1,000 characters for every second. The bar is engaged onto the outside of the material to be set apart with a F-theta focal point which guarantees the bar is reliably engaged over a working stamping territory. The spot size of the bar can be as restricted as 25 microns and moved with micron exactness.
The key is the remarkably high redundancy rate ability for our beat Laser at full Laser power; no q-exchanging implies no Q-switch constraint. The as of late presented Pulsed Fiber Laser utilizes a MOPA (Master Oscillator Power Amplifier) design, which utilizes a legitimately regulated seed Laser that is enhanced utilizing an exclusive Fiber Laser based enhancer chain. This thus permits the beat boundaries to be all the more successfully controlled. This plan empowers high pinnacle controls that are not accomplished with standard adjustment. Pinnacle beat powers in overabundance of 20kW can be accomplished at 30 kHz with a normal yield intensity of 40W. The unit additionally has a high beating recurrence extend from 1-1 MHz and with heartbeat widths in the 10-200ns territory. The Laser is likewise fit for working in consistent wave (CW) mode.
The MOPA course of action permits control of the beat shape, term utilizing a scope of preset heartbeat waveforms are accessible as appeared beneath. This adaptable command over heartbeat width and pinnacle power with the PulseTune work empowers exceptionally high reiteration rates while keeping up generally high pinnacle powers.
Sino-Galvo Tech. was founded in 2001, and our galvanometer scanners already have got CE, ROHS, FCC and REACH certifications, quality control in accordance with ISO9001 quality system standard, and we exported our products to many countries and regions.We also provide complete marking system including fiber laser marking machine, MOPA laser marking machine, production date batch number serial number laser marking machine and other laser equipment.
