We often refer to the high-quality materials that are used to construct Numberall machines. We even wrote a blog high-quality metal marking machinesabout why buying the materials for our products from the United States is so important to us; however, we wanted to give you a better idea of what exactly our equipment is made of – and why our materials make our high-quality metal marking machines so durable.

The Model 40B, our best-selling metal marking machine, is a great piece to use as an example. One of the first things you’ll notice when you pick up one of these machines is the weight. Most of this is due to the sturdy cast iron “C” frame that prevents deflection and uneven marking. We get our cast iron for our products from a Maine foundry company.    

In addition to the heavy duty cast iron we use for our machines, Numberall’s character dials are crafted from high grade American tool steel that’s precision heat treated for severe usage and long life. We require a certificate with our steel to verify its quality and origin – a step we’ve taken to ensure we provide you with a great product, and to save ourselves the hassle of working with lower quality imported steel as we manufacture our high-quality metal marking machines.

The parts of the Model 40B that are made with this American steel include the adjustable table, the precision threaded screws for spacing and depth of impression, the handle, the precision machine spacing rack, and the numbering dial, which is CNC machined, engraved S7 tool steel that’s heat treated to 58 on the Rockwell scale.

The Model 40B also comes equipped with a quick release for table return and rack and pinion power transmission to the table from the handle. A rack and pinion is found in various high-quality materials, such as the steering mechanisms in vehicles.
