Why is MOF used for laser marking of wires?
Correct Answer
A. Marking after an extruder requires continuous marking processes
Explanation
MOF (Marking on the Fly) is used for laser marking of wires because marking after an extruder requires continuous marking processes. This means that the wire needs to be marked while it is still moving, without any interruptions. MOF technology allows the laser to mark the wire accurately and efficiently while it is in motion, ensuring a continuous marking process. This is important for high-speed wire marking where the wires tend to fly, making it difficult to mark them using other methods such as ink jet. Laser marking is also faster than ink jet, making it a preferred choice for marking wires.
