Laser marking machines are more widely used than pneumatic marking machines. Laser marking machines can achieve general metal or non-metal marking, while pneumatic marking machines are generally only used for nameplate marking. In terms of working principle, laser marking machines are non-contact, and through the energy of laser, the part of the material to be marked is vaporized to form a logo. Pneumatic marking machines are mechanical and achieve marking through stamping. In terms of price, pneumatic marking machines are very cheap.
Generally speaking, although laser marking machines are expensive, they are more widely applicable and have a long service life.
