Ask anyone inside the industrial manufacturing industry – part-marking is crucial to component traceability when working with large quantities.
The Basics of Dot Peen Marking
If 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 Action
Dot 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 Marking
One 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:
New and exciting dot peen innovations have just been introduced! Be on the lookout for machines that feature:
Kurt J. Lesker Company® (KJLC®) is the leading global provider of high-quality vacuum equipment, that services the LEDs, Optics, UHV/Synchrotrons, Electronics, Wear and Decorative Coatings and R&D markets.
Leading Marks tested and installed a Gravotech XM500 ENv2 LM portable dot peen part marking system. The Gravotech - Technifor XM500 is a lightweight and robust portable marking machine with an ultra-compact design that allows you to mark where you want, when you want. It can be used for marking small and large parts as well as parts with complex shapes and difficult to access areas. Combined with the new XCOM Control Unit, the XM500 is the most comfortable and intuitive marking machine on the market!
According to Roxanne Shurtz, CNC Supervisor at Kurt J. Lesker Company, "Leading Marks was able to answer any questions that I had. The technical support was knowledgeable and efficient. I appreciated Leading Mark’s quick response time, knowledge of products, and product availability."
Our new Gravotech, handheld dot peen tool gives us the ability to quickly change our marking needs from job to job. The production staff finds it easy to understand and use. I would recommend Leading Marks because of their outstanding customer service and knowledge. They offer innovative products and ideas."
