There are a a number of ways to mark metal. Rotary Engraving ( CNC ) or Laser ablation and our Ceramic Laser Fusion method are but two.
Metal can also be printed via our ESCA-PRINT or META-Print capabilities: ESCA- PRINT is a direct to surface metal printing system: Ideal for exterior labels, nameplates and signs: Over-coated with UV Supershield long life clear.
Meta print is the printing into a clear coating ( polyester ) of images, text or full colour . Meta Print can provide you with photo realistic metal printed labeling for interior applications combined with economy.
The Sun Armor printing system gives quality exterior colour printing capabilities for labels, tags, name-plates and small signage systems. Designed for life ranging from 5 to 10 + years, depending on the positioning of the products
Laser Engraving or our Ceramic Laser Fusion system: Fuses ceramic frit into the Stainless Steel leaving a black indelible mark in the stainless steel. This method is highly popular for volume marking of Stainless steel labels, valves tags or other signs and identification for long life.
Common uses include Photographic ( monotone reproduction ) of images, artwork or technical details. The ceramic laser fusion is photographic standard in its reproduction, with a permanent finish.
There are a few requirements that must be met in order to Laser engrave or Laser Ablate a surface: Laser ablation is the removal of a coating or surface colour by the means of a Laser. An example is Anodized Aluminium, whether it be labels, tags , nameplates or sign, the Laser ablation method provides high resolution, fast (speeds), accuracy and consistency, laser m arked bare anodized aluminum will leave a low-contrast white mark on a silver background, but a high contrast on coloured Anodizing.
Laser Ablation, Ceramic laser fusion and Laser engraving are not just simple processes and choosing the right substrate combined with the correct marking method, finally over-coated with the best clear finishes are best left to specialist label and name plate manufacturers.
The cheapest price may deliver compromised surfaces, warping of metals, or set the surface up for breakdown due to corrosion. This can occur by a lack of technical understanding of the laser process. Raw metal surfaces can weaken and compromise the protective coating which makes the metal more susceptible to oxidation and rust.
Laser marking Stainless Steel or other Ferrous metals requires application of a ceramic frit in a predetermined manner, either by spray application or screen printing the coating, to a predetermined thickness. Too thick and the laser must “Burn” excesively and intensely, compromising the metal thereby weakening its mechanical structure and warping the metal.
Always ensure that you have all the correct questions asked of you, or that you ask the correct questions. Producing marked products is not just about the look and feel of the end product, but where the metal will be used. This information can help you find the best materials and best method to deliver the best result.
Once the end result purpose is discovered, it’s time to actually laser engrave the metal substrate. For photo engraving/marking, the higher the resolution, the better the engraving result. So always provide photos with high resolution.
We suggest always starting with the end in mind—what look does the client require, are there any environmental or durability issues you need to be aware of ? Ensuring the project is processed with the end in mind, helps determine what the best processes and materials are for the project.
Generally the biggest misconception by customers is that metal tends to be very expensive, granted metals have different processing requirements, these may not be so much a pricing issue when purchasing labels in volume due to the economy of scale production processes, quality manufacturers utilize.
There are many metal marking and printing methods available, so do not hesitate to ensure you provide the correct information to determine the best available process for your requirements.
