Product Marking

Metal marking is a process used to create permanent identification marks, such as serial numbers, date codes, or product codes on a product. These marks are created by using a marking device with characters or symbols to indent metal. Numberall manufactures the equipment that is used for the indenting process.

One of the simplest pieces of marking equipment is the hand stamp. A hand stamp is a rectangular piece of metal with a character engraved on one end. To create an indent of a character in an object, the character end is held against the product you wish to mark, while striking the opposite end with a hammer. The same concept holds true for our more complex equipment, but instead, a press is used to create the force necessary for indenting. In addition, some of our more complex equipment can automatically advance the numbers, to create consecutive serial numbers.
