Serialization solutions were an important marking application for traceability and identification in manufacturing even in the early 20th century. Many manufacturers and businesses used SCHMIDT’s numbering heads for this application. Numbering heads contained several character wheels that could be turned to bring up the next character in the serialization. This allowed users to mark a whole serial number at one time while also allowing for quick and easy changes in marking information.
SCHMIDT designed both manual and automatic numbering heads that came in a wide range of sizes. They were used for a variety of serialization applications.

This numbering head is used to fill several different spaces at one time. For example, if a tag requires data in three different locations, the spacing between wheels in the Repeat-O-Head can be adjusted so that the characters are properly aligned with each location on the tag.
Automatic Numbering Machines
Automatic numbering heads use springs to automatically turn the character wheels to the next number when triggered. These were commonly used for numbering name plates, machined parts, brass tags, and checks.
Large Numbering Heads
Large parts often required large numbering heads for a deep, clean mark. SCHMIDT’s large numbering heads were used to serially number automobile bodies, steel drumheads, and other heavy sheet metal parts up to 1/8” thick.
These automatic numbering heads were used for numbering car seals, tire labels, chicken bands, nameplates, and other products of light metal where raised characters were desired. These were made-to-order and were often highly customized.
Heavy duty embossing heads were used on 3/32” steel plates. They provided a serialization solution for barrel heads, automobile parts, and automobile bodies.
Modern Serialization Solutions for Marking Applications
Serialization solutions are even more important today for part traceability and identification. While customers still buy and use some of the above marking tools, many manufacturers and businesses have moved on to more modern marking technologies, like our GeoMARK lasers and Styliner® pin markers. Both utilize software that provides a simple serialization solution for your marking application.
