Laser marking instead of needle embossing

Similar to laser marking, needle embossing is used for industrial marking and surface finishing of a wide variety of materials such as metal, plastic, wood and leather. However, the choice of materials which can be processed using a needle embosser is limited in comparison to the laser marker.

Modern laser markers from JustLaser, however, can produce both ornaments, patterns, writings, as well as functional markings efficiently and precisely on a wide variety of surfaces. Whether individual parts or larger margins – they always convince with their maximum repetition accuracy and consistent quality.

In needle marking, pneumatically and electromagnetically-driven, oscillating hard-metal needles create a permanent engraving on a wide variety of materials. The marking itself consists of many small points which are pressed into the material by the impact of the needle, displacing the material in the embossed area. Two multiphase motors move the needle, both along x and y-axes and up and down.

While modern laser markers themselves are not limited in any way when it comes to marking hard metals, the relatively fine needles of needle embossers are subject to the rule that the harder the material, the higher the probability that they will break. That means that special diamond needles are needed for processing hard metals. As materials are processed mechanically in needle embossing, the process is usually very loud.

While it is certainly possible for embossing devices to create functional inscriptions such as barcodes, serial numbers, data matrix codes, etc., the technology is actually extremely low-contrast. This makes it difficult for these markings to be read automatically (and in the dark field). This is not the case with a laser marker from JustLaser. This creates an abrasion-resistant, permanent and high-contrast engraving which can be read reliably and precisely.

It doesn’t matter how fine, small or complex inscriptions, marks or ornaments turn out – the efficient laser marker from JustLaser can produce them quickly and easily on many materials. You’ll also benefit from a range of other benefits with our modern devices:

• Efficiency across the board: JustLaser Laser Markers are the most economic and gentle technology for marking a wide variety of materials. Our laser machines also convince thanks to their low investment risk, short processing times and high repetition accuracy. That means production costs can be kept low. Have we piqued your interest? We’ll be happy to calculate your return on investment (ROI) for you.
• High precision: laser markers from JustLaser always provide precise results. Even small components or elaborate motifs can be quickly and permanently engraved in difficult-to-reach places and made weather-proof and abrasion-resistant.
• Great flexibility: whether it’s metal, wood, stone or plastic – the laser process is extremely flexible and can be applied to a broad range of materials. Needle embossing, on the other hand, is rather difficult on hard metals, and cannot be applied to foils, ceramic, glass and textiles.
• Gentle technology: while laser marking is contactless and carried out without exerting any force on the material, the needle is push straight into the material in needle embossing. This makes laser marking ideally suited for processing delicate surfaces.
• Quiet procedure: as needle embossing is a mechanical technology, the procedure can occasionally be very loud. JustLaser laser machines, by contrast, produce very little noise.
• Easy to use: with our JustLaser Laser Marker, you’ll benefit from the simplest operation and quick process flows. You create projects in your usual graphics program and send them to your JustLaser laser machine via print command. Our laser software automatically selects the optimal parameters for you.
• Low maintenance costs: as lasers are contactless, a laser – in contrast to the needles on a needle embosser – does not become worn out after frequent use. This keeps maintenance costs extremely low and means that repetition accuracy and cut quality are incomparably high, even in serial production.
