Marking metal parts <\/strong>is a process in which an engraving or mark is made on the material containing a series of data, either in the form of text or numbers, which provide various information about the manufacture of the part itself.<\/p>\nThe materials that can be marked are diverse, however, in the steel industry, marking on stainless steel and metals such as gold, for example, are processes that have been standardized.<\/p>\n
[\/et_pb_accordion_item][et_pb_accordion_item title=”Metal marking techniques” _builder_version=”4.27.4″ _module_preset=”default” hover_enabled=”0″ global_colors_info=”{}” open=”off” sticky_enabled=”0″]<\/p>\n
At COUTH, we manufacture markers with different marking techniques for metal and stainless steel<\/strong>:<\/p>\nLaser marking<\/h3>\n
One of the most innovative techniques used in the metal marking industry in the steel sector, especially for mass production. This system uses a laser to mark the material with high precision. One of its main advantages is the exceptional durability of the machine, which ensures consistent performance over time.<\/p>\n
Laser marking in the steel industry <\/strong>uses a focused beam of light to modify the surface of the steel, creating permanent, high-contrast marks. It can be done by annealing (controlled oxidation), engraving (removal of material), or color marking, depending on the type of steel and the type of laser.<\/p>\nAdvantages:<\/strong><\/p>\n\n- No physical contact<\/strong>: does not deform or damage the part.<\/li>\n
- High precision<\/strong>: ideal for complex codes, logos, and variable data.<\/li>\n
- Speed and efficiency<\/strong>: suitable for large volumes and automated lines.<\/li>\n
- Durability<\/strong>: marks resistant to abrasion, chemicals, and heat.<\/li>\n
- Low maintenance <\/strong>and no consumables.<\/li>\n<\/ul>\n
Applications in the steel industry:<\/strong><\/p>\n\n- Identification of coils, sheets, bars, and components.<\/li>\n
- Marking of barcodes, QR codes, and Datamatrix codes for traceability.<\/li>\n
- Marking on stainless steel for the medical, automotive, and construction sectors. <\/li>\n<\/ul>\n
Micro-percussion marking<\/h3>\n
This is a metal marking technique that uses dot impact on the metal surface. This technique produces accurate markings that are easy to read on the part.<\/p>\n
How does it work?<\/strong><\/p>\nMicro-percussion marking in the steel industry uses a carbide punch, controlled by CNC (Computer Numerical Control), which impacts the surface of the steel, generating a series of micro-impacts that form characters, numbers, or codes. The depth and density of the marking are adjustable.<\/p>\n
Advantages:<\/strong><\/p>\n\n- Deep and permanent marking<\/strong>, even after surface treatments.<\/li>\n
- Resistant <\/strong>to harsh environments and handling.<\/li>\n
- Low operating cost<\/strong>: only requires replacement of the punch.<\/li>\n
- Flexible<\/strong>: suitable for large, irregular, or difficult-to-move parts.<\/li>\n<\/ul>\n
Applications in the steel industry:<\/strong><\/p>\n\n- Marking of ingots, bars, profiles, and large parts.<\/li>\n
- Identification of batches, serial numbers, and traceability in forging and casting processes.<\/li>\n
- Integration into automated production lines.<\/li>\n<\/ul>\n
Scratch marking<\/h3>\n
Using a tungsten carbide or diamond stylus, metal parts and even certain types of resistant plastics can be marked by making fine, highly precise incisions. It is also a silent marking system.<\/p>\n
How does it work?<\/strong><\/p>\n\n- Scratch marking in the steel industry <\/strong>uses a diamond-tipped or carbide punch that slides over the metal surface, engraving continuous, deep lines. The process is quiet and produces highly legible marks. <\/li>\n<\/ul>\n
Advantages:<\/strong><\/p>\n\n- Clear<\/strong>, deep, and aesthetically superior marks<\/strong>.<\/li>\n
- Quiet operation<\/strong>, ideal for noise-sensitive environments.<\/li>\n
- Low maintenance <\/strong>and high equipment durability.<\/li>\n<\/ul>\n
Applications in the steel industry:<\/strong><\/p>\n\n- Use on stainless steel parts, alloys, and precision components.<\/li>\n
- Marking of serial numbers, logos, and codes on finished parts.<\/li>\n
- Ideal for components where legibility and aesthetics are a priority.<\/li>\n<\/ul>\n
