Industrial marking is an extremely important aspect of any production process and for a number of good reasons. Firstly, manufactured materials need to be adequately marked. They need to be properly identified according to their batch number, date of manufacture and the actual material itself. This is crucial and as important as the manufacturing process itself.
There are a number of types of industrial markings, these include:
- Dot Peening – Dot peen marking is the method of using a special pin to mark a variety of variety of materials. As the name dot marking implies, the manufactured material or good is marked with a series of dots, which form straight lines or curves, making practically anything possible in terms of markings. The dots can be controlled in terms of depth, spacing and so on. This makes them extremely customisable and perfect for a variety of smooth and rough materials.
- Lasering – As the name implies a laser is taken to mark the material. Generally, this is very shallow and also produces heat and fumes from the process, making it much less effective than dot-peening. The depth of cut is also much lower, as laser markings tend to be only on the surface and require much more time for a deeper and more durable cut. Lasers are also not ideal for irregular or rough surfaces like the dot peening method.
- Scribing – This method is used for very small and fragile applications, such as marking things like microchips or very small parts. The result is similar, but the machinery is much smaller and more delicate than lasers or dot peens.
Why is industrial marking so important?
As we mentioned above, one of the main reasons for industrial marking is being able to identify materials, where they come from and so on. Imagine a scenario where a material is deemed to be faulty, it would naturally need to be recalled, but how would you know which particular materials? This would naturally come from the identifying number, that would be printed, lasered or dot peened onto the surface of the manufactured product.
Industrial marking is also important to the end consumer because they can learn more about the origins of their product and help them to identify what they need. For example, imagine a company that uses steel rods, but uses a number of different types of steel. The industrial markings would show exactly what kind of steel, as well as other important information. This is particularly useful where a number of similar products are used in the same place.
