Laser Marking

Major marking methods are as follows:

- Laser marking

Irradiate a laser beam on a material to change and color it. Marking contents can be easily changed using a software. Clear fine marking even on tiny parts is possible.

- Inkjet printing

Shoots a jet of micro-particles of ink to mark with dots. An inkjet printer used with a personal computer, and a printer for industrial-use to mark best-before-date on laminated film are the major applications.

- Ink stamping

Presses ink-supplied relief or intaglio onto an object to mark. This is the most popular method from the past. Though the equipment is less expensive, production routine cost is relatively high; additionally, it requires to control ink.

- Punching

Presses a numbering head, on which desired marks such as letter, character are engraved, onto an object. This is widely accepted for marking on metal. While the mark is very reliable and ever-lasting, this method is less productive and needs much time to change the head.

It is as follows:

- Environmentally friendly and easy recycling.

Unlike the marking with ink, no solvent is required. Since no ink sticks to base material, it is recycled easily. Also manufacturing process is reduced remarkably.

- Marking not erasable

Since the laser beam changes a material itself, the mark is never erased, unlike an ink-using method. This marking complies with quality control requirements in PL Laws and ISO International Standard.

- Micro-marking

Lasers are capable of fine marking which inkjet marking can never perform. It is the best suitable choice for microelectronic parts.

- Easy to design and change marking contents

The marking software is easy to use, so can design marks easily and can switch to other marks easily at your PC. Laser markers are suitable even for a small-volume production of diversified products.

- Productivity-improving and labor-saving

The high-speed marking contributes to improvement in productivity. The relatively easy maintenance saves labor. Production line can be easily automated and operates unmanned in the nighttime.

- Wide range of laser-markable materials.

Various materials such as metal, resin, ceramics, semiconductors, paper, glass are acceptable; in addition, laser marking also accepts material with oil film in which inkjet printing has difficulties.
