Numberall Numbering Head Model 50P

Numberall’s Model 50P automatic numbering head represents the finest marking device in the industry for rapid and accurate consecutive numbering. Like many of our other marking devices, this model’s road to becoming a well-known device in the metal marking industry is unique. Numberall produced the first Model 50P in the fall of 1935, after many months of planning and engineering. The goal was to provide customers with a machine that could precisely and efficiently mark a number of materials consecutively with minimal effort from the operator.

One of the first Model 50Ps that came out of production was purchased by a company we still do business with today. In 1936 Ketchum Mfg., an identification tag manufacturer in Lake Luzerne, NY, bought the 13th Model 50P that was produced. Like Numberall, Ketchum is a multigenerational family-owned company. Mr. Hopping, one of Numberall’s employees who was in charge of producing the Model 50P at the time, made note of the sale to Ketchum Mfg. in the serial number pages seen below.

Many years later we were able to obtain Ketchum Mfg.’s Model 50P, which they had modified over the years, to display in our archives.

Numberall has manufactured thousands of Model 50Ps since the first production over 8 decades ago. Through the years, the 50P has been steadily improved to increase its effectiveness and usability for clients with various uses. For example, we added a pawl block to improve wheel alignment and operation. Each wheel is now one CNC-machined component, and the actuating pawl is CNC wire EDM machined. We’ve updated the machining methods of other Model 50P parts for smoother operation and less hand fitting. It is because of this commitment to quality and durability that we are still servicing numbering head units that are over 40 years old. 

Like all our machines, this model is built with heavy duty tool steel and is precision heat-treated for extensive usage over a long product life. Today’s Model 50P offers:

  • An ideal solution for rapid, accurate, consecutive marking
  • Precise wheel alignment
  • Zero suppression standard (to eliminate prefix zeros)

In addition, the Model 50P is compatible with a variety of optional equipment to increase its versatility, including hot stamping equipment for marking plastics. Numberall also offers custom applications for the Model 50P, such as an extended frame leg for a removable logo die, allowing for custom serialization.

After decades of producing and perfecting this model, you can be sure that the Model 50P is equipped for high quality marking for many years to come. If you’d like to learn more about the Model 50P, or request a quote for a custom application, please contact Numberall Stamp and Tool today.
