Fundamentals of Laser Marking

1/24/2023

0 Comments

 
Created via Chat GPT, Edited by Bernard Martin
Laser marking is a process in which a laser beam is used to mark or engrave an object. The laser beam is directed at the surface of the object, and the energy from the beam causes a change in the surface material, resulting in a permanent mark.

There are several types of laser marking, including annealing, engraving, and foaming. The type of laser used, the material being marked, and the desired outcome will determine the specific process and technique used for laser marking.

​Common materials that can be laser marked include metals, plastics, and ceramics. Laser marking is often used in industrial settings for product identification, traceability, and branding.

The term "laser" stands for "Light Amplification by Stimulated Emission of Radiation," which summarizes quite well exacty how lasers work. Light particles, called photons, are excited with an electrical current, causing them to emit energy in the form of light. This light forms the laser beam.

The principle of industrial traceability by laser engraving is based on a beam of high intensity laser focused and then directed towards the part to be marked.  Its orientation is ensured by a galvanometric head composed of two mirrors. When a laser beam hits a part's surface, the energy is transferred in the form of heat, creating black, white, and sometimes colored marks.

In manufacturing, Lasers  are a permanent, a precise and qualitative marking solution for part identification and traceability. Different applications may require different marking techniques such as engraving, staining, removing, annealing, and foaming are the most common marking methods. Each laser marking procedure will have its own unique advantages and disadvantages, depending on the materials being used and the quality requirement.

Types of Materials to Laser Mark

Picture

Many different types of materials can be laser marked, including:
  • Metals: Stainless steel, aluminum, brass, and titanium are common materials that can be laser marked. The laser beam melts or vaporizes the metal, creating a permanent mark.
  • Plastics: Many different types of plastics can be laser marked, including polycarbonate, ABS, and polyamide. The laser beam causes the surface of the plastic to change color, creating a contrast between the marked and unmarked areas.
  • Ceramics: Ceramic materials can be laser marked by removing a thin layer of the surface material. This creates a contrast between the marked and unmarked areas, making the mark visible.
  • Glass: Laser marking on glass is done by a process called scribing, which involves using a laser beam to create a crack in the surface of the glass.
  • Wood: Wood materials can be laser marked by burning the surface of the wood, resulting in a dark mark on a light background.
  • Some fabrics: Laser marking can be used to print on fabrics such as denim, cotton, polyester, etc.
It is important to note that not all materials are suitable for laser marking, as the energy from the laser beam can cause damage to some materials. Additionally, the type of laser used and the specific laser marking process will be determined by the material being marked, as well as the desired outcome.

What Kinds of Marks

Picture

There are lots Steel Stamps and Dies available off-the-shelf to meet many of your everyday needs. But when you need something custom or unique, it's good to know that we can have that made for you too!  Here are some things to things you should know about steel stamps and dies. 
Stamping Dies
An example of a stamping die
Steel stamps and marking dies are custom engineered for identifying a variety of industrial products. Every die blank is machined to the user's specifications. Custom dies satisfy any user requirement for marking machines, punch presses, press brakes and other machines.
​

Custom stamps can be made for marking on flat, curved, concave or convex surfaces - for stamping part numbers, patent numbers, trade names, trademarks, special lettering or other data. 

Embossing Dies

Steel embossing and coining dies are most often used in the sheet metal industry
This process can be made by means of matched male and female roller dies, or by passing sheet or a strip of metal between rolls of the desired pattern. It is often combined with foil stamping to create a shiny, 3D effect.

These male and female dies produce permanent and legible raised letters, including trademarks, code symbols, ornamental patterns, or virtually any specific design, on various gauges of sheet metals.
Embossing Die
There are some pretty hot examples of embossing dies.

Roll Dies

For marking parts being machined on an engine lathe, turret lathe or screw machine, these rolls can be made for one or more lines of interchangeable type, or with combinations of solid logotypes and individual characters.
​Roll dies can be made for one or multiple of interchangeable type and customized with combinations of solid logotypes and individual characters.

​You can also get a  number of character options including:
  • Sharp face
  • Low stress round
  • Low stress dot
  • Flat face
  • Concave face
  • Convex or spherical

Steel roll dies offer users a number of advantages. One of the most apparent advantages of steel is life span. Steel is a durable material that offers users a long service life, making steel roll dies a cost effective solution. 
​

Steel roll dies also create clear, permanent marks and are strong enough to mark a wide range of materials such as metal, plastic and wood. 

Custom Steel Stamps, Inserts, Segments and Dies

You can also get custom steel stamps, steel inserts, steel segments, shank stamps and various stamping dies that allow you to direct part mark just about anything.
​

Custom stamps, inserts, and segments can be made for marking on flat, curved, concave or convex surfaces - for stamping part numbers, patent numbers, trade names, trademarks, special lettering or other data.

Steel marking dies
When people think of direct part marking the first thing the often comes to mind is steel marking dies
In essence, Direct Part Marking (DPM) is applying identification that lasts from cradle to grave and will sustain very rugged environments. Many US government agencies are making unique device identification (UDI) and direct part marking (DPM), mandatory. The private sector, from automotive manufacturers to medical offices have been using DPM more and more as they have embraced the Deming Principles of TQM. 

​Direct Part Marking is used most frequently when marks are needed on a variety metals, plastics and wood. Common equipment solutions range from traditional hand stamping processes to cutting edge technology of fiber laser marking. Direct part marking is often a less costly alternative to purchasing RFID tags.

When to Choose Direct Part Marking

Picture
  • The part is too small for a barcode label
  • The item will be exposed to environmental conditions that traditional labeling may not withstand
  • When it could be more cost effective to DPM over barcode labels
  • If identification or data must be tracked throughout the life of the item
  • If the item could be marked during the manufacturing process
  • The ability to track items in high-temperatures and other harsh environments
  • Providing more accurate and reliable part identification
  • Preventing errors in just-in-sequence production
  • Eliminating manual data collection approaches for inspections, inventories, and maintenance reports
  • Ensuring the lifetime traceability of each part
  • Enabling track-and-trace initiatives that provide chain-of-custody tracking and protect against product diversion
  • Reducing or eliminating counterfeit parts by providing end-to-end traceability using a method that is difficult to duplicate, and doesn’t rely on package marking
  • Enabling more comprehensive inventory management

Direct Part Marking Options

  • Traditional options range from steel hand stamps and holder/type arrangements to various numbering and impact presses, including roll marking machines
  •  Advanced technologies such as dot peen, scribe and laser marking machines enable marking processes to be done automatically communicating with other manufacturing technologies and allow the addition of machine readable codes for component traceability.

2D Codes: Most Popular for Direct Part Marking

In most cases, direct part marking applications use two-dimensional (2D) barcodes such as Datamatrix or QR Code, which carry much more data than linear (1D) barcodes. By using 2D barcodes, manufacturers can also identify very small items and parts​​.
Dot peen vs vibra peen vs scribe DPM Part markingDot Peen vs Vibra Peen vs Scribe and a 2D QR code
2D codes can pack a large amount of data as opposed to linear codes because they can carry data in two directions on the code vs. just one.  To give you an idea of the relative size, a 1D barcode can store around 25 characters up to about 80 characters depending on whether it’s Code 128 or Code 39, but a 2D code can store up to 2,000 characters.  

In the automotive sector, there is an established standard (AIAG B11) for direct part marking, and a number of large auto OEMs like Ford require suppliers of certain components to use DPM for part traceability.

​Manufacturers like to use the 2D code not only for the storage capacity, but for their relative size as well (square vs. rectangular).  The flexibility of a 2D code allows for the variation in the amount of information stored in the barcode as well as the size of the item being marked.  The most popular uses of the mark are for applications that require:
  1. Traceability
  2. Verification & Error Proofing
  3. Part Identification

Fundamentals of Labeling BePop 100P1
Labeling allows identification to be applied and maintains component integrity with no deformation to the surface.

Optional adhesives allow the labels to be used in various environments and offer tamper-evident options for security. While there are cost savings in some instances to have labels pre-printed and ready for on-demand application, at other times there is a distinct benefit to printing labels on-demand where label design is done in-house for quick edit corrections or job-specific requirements. 

Printing In-House

In house printing provides flexibility for label details and printing/applying in individual work cells. Volume printing can be maximized through stocking materials for just-in-time printing.
If you want to see some of these tools in action,  check out the video below.

Pre-Printed Labels

There are some rather unique challenges associated with marking different materials.  Here's a short overview of things to think about.

Metals

Custom Foundary Die

There are various types of metal marking methods, each of which has its advantages and disadvantages. Three popular types of metal marking include indent, chemical etch, and ink marking. Various methods of marking can be used to mark alpha-numeric, logos or bar codes on metals whether they are bare or painted surfaces – flat or curved surfaces. You can also have an engineered solutions for any kind of mark on any type of metal – from steel pipe to sheet metal to 2D codes, barcodes, large or small character marks, and everything in between.

Plastics

Picture
Plastics require consideration of the chemistry. Hot stamping is most favorable for branding and decorative identification or an application where color contrast is important. Direct indented marks may have challenges for permanence especially if the plastic does not have a memory or if it is too brittle. Labels may not adhere or require very rugged adhesives. Corrosion may be a challenge with inks.

Wood

Variations in woods offer challenges for marking applications. Hard woods result in better direct-part marks, where soft woods may be too porous for good ink marks. Smooth surfaces yield better results when hot stamping or branding. Rugged adhesives for labeling offer longer sustainability especially when used on shipping containers.

Other Materials & Components

Picture
Precious metals can be marked with impact, dot peen or other non-invasive methods, while concrete is best served with inks, and glass with labels. Circuit boards are commonly marked with labels or chemical-etch processes that are being replaced by laser marking. Specialty equipment may require decal kits for branding, as well as serial plates for warranty identification.

Whatever the material substrate to be marked, options are available to suit your requirements and budget.  Leading Marks wants to help you identify solutions and improve your processes.

Stamps & Stencils, Portable Devices, and In-Line Systems apply marks directly onto product without disturbing the product integrity and eliminates the need to apply labels where adhesive may be a deterrent. Electronic devices provide versatility of changing marking detail quickly and automatically.

Varying ink options provide contrast to the substrate or when needed to define a process designation. Whether your need is in the manufacturing or packaging process, or at the final stage of shipping, current marking devices improve the process where industrial markers and stencils were  common tools of the trade.

  • Stamps & Stencils most commonly used in hand stamping operations with rubber stamps, self-inking stamps or rubber rib-type & rollers. Oil-board or mylar stencils as pre-cut made-to-order or made in-house with manual or computerized machines are inexpensive options for larger text requirements or when applying shipping details.
  • Portable Devices improve the legibility of manual ink stamping operations, as well as enable the marking details to include bar codes for improved traceability.
  • In-Line Systems are most commonly used for automated lines where traceable identification such as batch, heat or product numbers need to span the length of a product, or application of the mark is done while the product travels through the production line.
