Manufacturing has become increasingly dependent on marking manufactured products with lasers. A growing number of companies are keeping track of their products to reduce expenses and manage inventory. Traceability, according to manufacturers, will ensure suppliers follow quality standards, enhancing the quality of their products and reducing recalls and counterfeiting.
However, finding the right marking technology for your business and product is not easy. Marking technology, which comprises dot peening, laser engraving, inkjet printing, and electrochemical etching, is a broader category. Prior to making a choice, it is important to understand the pros and cons of each. Suppliers typically select a marking method based on a number of factors, such as the type of material, functionality, surface roughness and finish, mark size and dimension, mark quality, coating thickness, and serialization.
Direct marketing becomes mainstream
Direct part marking, or DPM is used by a large number of manufacturers to permanently mark parts with serial numbers. The primary reason for this is that conventional marking techniques such as stickers do not allow for full life-cycle tracking. This method is quite popular among manufacturers; it is used by specialists to identify medical parts. Engravings typically take the form of alphanumeric characters, barcodes, or data matrix codes. Automating post-manufacturing processes, such as serial and batch matching, or stock management, can be achieved by using barcodes when marking parts.
Benefits of laser marking
Generally, Marcatrici laser prezzo offers a number of advantages because it is fast and permanent. It has a lower cost of ownership, doesn’t require any additional steps to ensure durability, and uses no consumables, so waste is minimized.
Technologies used for marking
Marking with inkjet
Inkjet marking uses pressured ink to mark a surface without contacting it, also known as “on-the-fly marking.” The two types of inkjet-based systems are continuous inkjet (CIJ) and drop-on-demand (DOD). For the marking to be created, both materials must be moved. DOD is a technique for creating marks by using nozzles that deposit dots without steering. The size and resolution of the marks are determined by the distance between arrays and nozzles. CIJ involves the use of charged ink droplets, which are oriented perpendicular to the material, to create characters. As the parts move away from the nozzle, a dot matrix character is formed.
Electrochemical etching involves corroding materials using specific electrical and chemical processes. An oxide black surface is a result. Marking can only begin once the area to be marked has been thoroughly cleaned. A pre-produced mask must then be used to cover the material. A solution of electrolytes is then applied to cover the material.
Because the electrode must make contact with the material, the process may take a few seconds to a few hours, depending on the level of penetration.
Due to its clean and fast nature, laser marking is rapidly replacing traditional engraving. The advantages of laser marking include ease of automation, low ownership costs, and a greener profile, which all contribute to its success. Manufacturers can choose from many different laser varieties. Based on their characteristics, each laser type is best suited to a specific application or material. The most common lasers used for universal material marking are carbon dioxide, ytterbium-doped fiber, ultraviolet, green, and neodymium vanadate lasers.
If an engraver wishes to engrave expensive machinery or products, he must be very cautious. A single mistake can ruin the entire product, and no one wants that to happen. With laser printing, you don’t have to worry about any of these things. You won’t have to worry about the engraving getting damaged, as it will be precise.
Laser markings are of high quality.
Laser marking does not require etching the product or applying ink to the surface. Ink can be replaced by lasers to produce marks that are damage-free.
Using Apple LaserMark, a Samurai UV Laser Marking System, we mark our parts at Apple Rubber. Since its beam quality is high, smaller spot sizes can be produced by the laser. The combination of small spot size and short pulses produces high peak power, which is beneficial for deep marking with crisp, clear marks and small characters.
