- The vacuum table version features a separate motor to actuate the cutting head with absolute precision. This model has rubber pads placed on top of the work area, which minimize noise during the operation of the machine.
Industries Where Dot Peen Is Used
Dot peen marking machines are being used in various industries these days. Here is a brief overview of some of the common uses of dot peen marking tools in these industries.
Forging Industry
In the forging industry, this tool is used to mark identification marks on forged products like iron castings, structural steel shapes, and forgings sent for heat treatment or complete finishing (also known as a cold heading). In this process, the dot peen marking tool is set up as a backup to transfer fewer characters than hot stamping. However, forged products must have identification marks on the heat treatment process or complete finishing. The markings mentioned above are often referred to as part numbers, and these markings must be visible on the surface of the metal.
Casting Industry
For marking identification marks on castings, the dot peen marking tool is mostly used in this industry. Dot peen markings help to prevent theft or easy identification of valuable components within the castings during various production cycles of these components. A manufacturer can easily draw identification logos and part numbers on castings using a dot peen marking tool.
Stamping Industry
The stamping industry is one of the hardest-hitting metal forming processes that use many metal parts, especially aluminum. In this process, a steel die is used to hit a blank repeatedly until the desired shape is achieved. The blanks are often pressed from sheet or ingot stock at high pressure, which causes them to have distortions or uneven markings
To avoid such unwanted conditions in the finished products, the dot peen marking tool is used in this industry to mark identification marks on the blanks before they are formed. Once these markings are imprinted on the surface of the blank, they will become noticeable when stamped products are examined under proper lighting conditions after the finishing process.
Rolling Industries
Dot peen marking tools are also used in rolling mills to mark identification marks on the rolled metal sheets. Dot peen marking device is mostly preferred for this purpose. It can help manufacturers transfer information more specifically on the surface of the finished product without leaving any visible impression of markings. The only drawback of using dot peen marking tools in the rolling industry is that they can damage or remove the surface of the metal.
Food Processing Industry
In the food processing industry, a dot peen marking tool is used to imprint date codes and other identification marks on various food products later packed into cartons or jars before they reach their destinations.
Laboratory Industry
In this industry, identification marks are often imprinted upon various products tested in laboratories before sending them to the customers. Dot peen marker is used for this purpose as they can help lab technicians print a large number of identification marks on a small surface area very easily and quickly. These markings will remain there until the products undergo further modification or customization.
Purchasing Industry
In this industry, dot peen machines are used to mark identification marks on raw materials transported into the factories from suppliers and vendors for further process. This helps manufacturers review delivery receipts, catalogs, or purchase orders to look up original orders and avoid possible mistakes.
Manufacturing Industry
In this industry, the dot peen marking system is used for engraving identification marks on the various metal components before they are further processed in the manufacturing processes, including casting or forging, machining, or forming. This avoids any chances of mistakes in product level inventorying and helps manufacturers maintain proper control of their products with ease.
Electrical Industry
In this industry, a dot peen marking tool is used to mark identification marks upon various metal components before they are assembled in different electrical devices to avoid any mistakes during the assembly process.
For instance, when an accumulator requires repair, the other parts attached or assembled should be marked beforehand. It will help manufacturers determine what component is needed instead of blindly searching for other parts that could also fit in by accident.
