A fiber laser has an output of 1064 nm and is offered in two variants: the Q-switch and MOPA. Fiber lasers operate by either pulsing or continuously broadcasting the light onto the part. Fiber marking lasers are all pulsed lasers. Continuous wave fiber lasers are usually 200 watt or higher and are intended for cutting metal.
The Q-Switch operates by pulsing energy (amplified light) onto a part. The pulse cannot be modified in terms of duration and is fixed. These are considered the standard fiber lasers in the marketplace. Industry standards are 1-200 kHz, while the Automark AMFQ series line operates at 1-400 kHz. Our Q-Switch lasers provide a higher frequency than others in the marketplace, allowing a greater range of printing capabilities, for printing darker on aluminum and printing on an expanded range of plastics. It bridges the gap between a traditional Q-switch and MOPA fiber laser.
The MOPA (Master Oscillator Power Amplifier) allows for the pulse of the laser to be adjustable. This offers finer detail as the substrate around the affected area is not transformed by continuous waves of heat. In addition to the pulse duration, the frequency itself is expanded to allow more control. The frequency is 1-1,000 kHz, which means a larger amount of substrates, like polypropylene and marking white on PA plastics can be marked. The high degree of contrast also continues with the ability to mark black on aluminum and multiple colors on stainless steel.
MOPA fiber laser systems are also the choice for many medical applications, as they are more permanent, and survive repeated cycling during sterilization.
So easy to use these units run on any PC running Windows. Its software allows for quick and easy marking of parts. Mark and engrave images, shapes, text, bar codes, QR codes, micro QR codes, and even self-changing (dynamic) marks like serial numbers, dates, and more. These lasers are built with 7 I/O ports, the ability to hook into robotics, and will even allow users to push data directly into the machine through database synchronization. Watch our video to learn more.
We offer three main laser configurations. The U series (Upright), O series (Open) and the E series (Enclosed). The U and E series share a viewing window and Class I reduction of the Class IV laser. The U and O series have 300 mm work areas, whereas the E series has a 200 mm work area. All laser specifications are the same across the lineup. For firearms, the O series is popular as it allows the full length of the firearm to rest under the laser.
Substrates can include titanium, brass, steel, nickel, iron, aluminum, and other metal alloys. Fiber lasers can mark limited ceramics, polypropylene, PA, and other thermoplastics. To see if we can mark your part, feel free to reach out to us as we offer free ink adhesion tests.
15% Faster Than Any Leading Competitor
Our AMFQ and AMFM line of fiber lasers operate at 7000 mm/s, which is about 15% faster than any other leading competitor’s lasers, meaning higher throughput and even greater returns.
Lasers are regulated by the FDA due to the radiation they emit and are classified based on the damage they can do to skin and eyes. A Class I laser is a laser that is totally enclosed with no way for the beam to escape. This is similar to a laser desktop printer and cannot cause eye or skin damage with normal use.
A Class IV laser is the highest classification of laser, meaning they can cause significant skin and eye damage. Class IV lasers can cause damage even if viewed indirectly. All of our lasers, when operated properly, are extremely safe.
Operator safety is paramount, so we offer an entire line of lasers that transforms a Class IV laser into a Class I laser by enclosing it in a sealed box. This is the E line of fiber lasers.
If your company is seeking a laser and you would like to further discuss the safety aspects our reps can answer questions and guide you. Feel free to contact us today.
Standard lasers have a focal point with a tolerance based on the distance from the lens. This varies and depends on the lens size selected. This focal height is only a few millimeters. Round parts are challenging for two reasons. The first reason is the distance is changing as the slope of the Z-axis declines around the part. The second reason is because the center point of the galvanometer is creating a “longer” traverse to create the same image. This means that if a person was to use a standard, 2D, laser to mark a round part, they may get elongated markings as the beam trails off over the edges.
To counter this, we can use two separate systems, independently or together:
We can use a rotary to hook the part onto and spin the part. The rotary feeds information into the laser, so the laser knows where it needs to mark. This is done if greater than 120 degree printing is required. Smaller rotaries, like 50mm, are perfect for rings and small items, whereas the larger 100mm rotaries are perfect for mugs and firearms.
3D LASER SYSTEMS
A second way is to use a 3D laser system. This is a laser specifically built to dynamically change the focal point inside the system. This provides the ability to print on 60- to 100-degrees of the part.
We offer laser solutions for moving parts, such as bottling operations, assembly lines, and conveyor belt delivered part marking. Special photography can be implemented to identify part orientation, so fixtureless printing is capable. For details on this and other customized solutions, contact us to discuss your program in detail.
