Roll marking is a very specific style of marking machinery that looks distinctly different from any other piece of machinery in the category, because of the large rollers that do the marking and must be set up at just the right angles. All machines must be very carefully engineered, whether they are for roll marking, laser markers, hot stamping machines or equipment unrelated to the marking industry. Factors such as dimensions, tolerances and orientation of all the pieces must be carefully mapped out before the metal material is even purchased to start building. Once the material, usually something sturdy and strong such as stainless steel, is purchased it must be measured on a number of different levels so that the strip width, material gauge and physical properties are all correct for the service it will need to perform. Some metals will also require additional processes after they are machined but before they are built into the roll marking machine to increase positive characteristics such as water and chemical resistance. Ensuring that the metal being used to create the structure and individual parts of manufacturing equipment are always the best they can be is very important from a designer standpoint. Once the roll forming machine is manufactured, proper inspection is another key step in ensuring the piece of equipment will be in excellent machining condition. The main function of a roll marking machine is to imprint cylindrical or flat parts with characters and designs, which is done in an even pattern at an even depth because of the way the machine is set up. They can be designed for automated or manual operation, depending on the industry purchasing them and how many parts they will be marking. Mass production obviously requires an automated roll marking machine that would be incorporated into an assembly line. Considerations such as where the machine will be used and how often it will be used are other important aspects to keep in mind when designing a roll marking machine. Source: markingmachinery.com
