This article is originally from Technomark entitled: "What Is Dot Peen Marking? Ask anyone inside the industrial manufacturing industry – part-marking is crucial to component traceability when working with large quantities.
The Basics of Dot Peen MarkingIf you took apart a Dot Peen machine, one of the most important components you would find is a carbide or diamond-tip stylus. The Dot peen process is considered a “low-stress” marking method because the mark is generated via material displacement rather than material removal. The carbide stylus strikes the material surface to produce the mark via a series of cold-formed stamped dots. Compared to Laser Marking Systems, Dot Peen does not induce thermal shock to the part surface since the material is cold-stamped rather than super-heated to produce the mark. Dot Peen systems are commonly used by manufacturers in the aerospace and oil & gas industries where low-stress marking is required, such as tubular and flow control products that are exposed to extreme pressure differential in the oilfield. Dot Peen marking is viable for material hardness up to 63 HRC. Typically, when a part hardness is greater than 63 HRC, laser marking systems are recommended. All of Technomark’s Dot Peen machines rely on an electromagnetic solenoid to actuate the marking stylus. Dots are plotted in an X/Y plane via electronic control for precise placement of the Dot pattern. Using electromagnetic force versus pneumatic also provides a greater level of control of both the depth of the mark as well as the ability to mark contoured or complex surface. Dot Peen Marking: Component Traceability In ActionDot Peen marking machines are utilized in almost every industrial-goods manufacturing operation, including:
While these machines can run in-line and handle large quantities in an automated production environment, most are operated manually using a battery pack to go mobile.
Whether the part has a curved, wavy, or complex geometry, the stylus will follow the contour of the marking surface while maintaining a constant depth of marking throughout. When structural integrity is crucial, Dot Peen marking provides a low-stress marking solution that removes no material when marking the part. Why Choose Dot Peen MarkingOne of the biggest benefits of a Dot Peen Marking Machine is its ability to efficiently produce marks compared to other marking systems. Other benefits of Dot Peen machines include:

Stamping presses combine the customization of steel stamps, type, and dies with medium- to high-volume repeatability in an easy-to-use marking machine. Stamping presses, also referred to as impact presses, are either manual or pneumatic marking machines that incorporate a holder filled with steel type, a shank stamp, a roll die, or a numbering head above the marking surface; force is generated by compressing and then releasing a spring inside the press, and then the die is driven down which transfers the image from the face of the die onto the surface being marked. Stamping presses can be integrated into a production line or mounted, like the one in this video, on a bench top. In this video you can see a manual, spring actuated press in action. Why Use a Stamping Press?Stamping presses are an excellent marking solution for repetitive indent marking applications. They are low maintenance machines that are relatively straight forward to use. Manual impact presses, in particular, are easy to operate. One of the most important advantages of a stamping press is that it combines the flexibility and customization of steel stamps, type, dies, and numbering heads with machines that are ideal for medium- to high-volume applications. Stamps, type, and dies can be customized with logos or custom fonts and are manufactured from hardened, high-grade tool steel for long service life and durability. How Do They Work?
Manual Stamping PressesManual impact presses offer users a safe, reliable marking solution that is easy to set up and to operate. This manual style of press is best suited for low- to medium-volume applications. If you're not sure whether you need a manual or pneumatic stamping press, or have any other related questions, please contact us here. Unlike more complicated marking solutions, manual impact presses are low maintenance solutions that are easy to set up and operate. The simplicity of the manual press, coupled with the degree of control it offers, its safety, and reliability, make it a popular marking solution. Specifically, high volume repetitive indent marking applications are best handled with the use of impact presses which achieve a very short cycle time that cannot be met with any other marking method. Pneumatic Stamping PressesIdeal for high-volume applications, pneumatic impact presses can do more than just stamp. Pneumatic impact presses can be used for part marking, riveting, pressing, assembly, stamping, forming, punching, and shearing. This style of press can be operated either manually or with a control package (higher volume applications typically dictate use of a control package). See further below for more information on control packages. When selecting a pneumatic press, there are a few specifications that you should consider to ensure that you are selecting the correct press for your particular marking requirements. Of course, your Durable sales rep can help you with all of the options and features, but in general, the three main areas you will need to consider are the press model, the control package, and the marking dies. Choose Your Pneumatic Stamping Press Model
Choose Your Pneumatic Stamping Press Control Package
Choose Your Stamping Press Marking DiesPneumatic presses can make use of shank stamps, steel type with a holder, or numbering headsfor sequential marking. Your marking requirement will usually dictate which marking dies make the most sense. There is no right or wrong answer when it comes to choosing between a stamp, type, or numbering head. All three are machined from high quality, long lasting steel and can be customized. Numbering heads, however, are designed for serial numbering and sequential part marking, so they are not ideal for all applications Stamping Press ApplicationsThe popularity of the impact press is also due to its versatility. An impact press can be used for a wide variety of applications other than marking including:
Stamping presses are typically found in industrial and manufacturing settings, and over the years we have helped a number of companies find the right press for their particular application.
 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
Direct Part Marking Options
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 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:
 Leading Marks can help you with traceability from the shop floor where machine to machine communication and data-collection is crucial to mobilizing reporting from the warehouse or in the field.
Traceability is common for collection, look-up and sharing of data. Whether it is Asset Tracking, EH&S Inspections, QA/QC Controls, Work-in-process, Assembly builds, or Field Service reporting industry is driving the need for traceability from cradle to grave. Why is traceability important for your organization? What’s the value-add with the potential of data collected through mobile apps or plant-floor software packages?
