Dot Peen marking or engraving is a process that allows manufacturers to make deep, permanent impressions in a variety of materials for identification and traceability. Also known as "pin marking" or "pin stamping", this marking process involves
a carbide or a tungsten carbide pin that directly impacts a material to create a mark.
When programmed, Dot Peen can permanently mark human- or machine-readable information such as:
- Date/time stamping
- Part serialization
- 2D Data Matrix bar code
- Operator identification.
Benefits of Dot Peen Marking
Some applications, such as Oil and Gas pipes, require deeper marks than others. How do you know if dot peen marking is the best method for your applicaiton?
Two key reasons why manufacturers from a wide range of industries choose dot peen are its high-speed marking and deep engraving capabilities. increase productivity and decrease waste. Dot Peen markers deliver a mark that includes programmable character depth and size. Dot Peen marking is also the least intrusive impact mark method.
What is the Difference Between Dot Peen and Laser Marking?
While both dot peen marking (or pin marking) and laser marking are direct part marking methods that create permanent, readable marks on a wide variety of materials, it's important to have use the right method for your specific operation. Before choosing a marking technology, manufacturers should consider a number of factors, including part surface quality, barcode location, and connectivity to the factory floor. Taking the time to find the right solution can save costs as well as frustration.

How Does a Dot Peen Machine Work?
These machines mark using a single pin or multi-pin device to careate a specific dot pattern in each character. Dot peen machines can be either electric or pneumatic pin marking systems.
There is a direct correlation between striking of the stylus and the X-Y movement of the head.
