Fiber Laser Marking for Stainless Steel
Stainless steel is one of the most widely used engineering materials, it can be used in various industries and fields. From consumer goods to cookers, from surgical instruments to rooftops, stainless steel is the material of choice. Stainless steel has more than 150 levels, the difference of surface finish degree is more dazzling, there is always a certain kind of requirements to meet everyone. In contrast, fiber laser marker is also the most widely used industrial marking tools. The combination of the two will have unexpected effects.
Many stainless steel goods and components require a logo, whether it's a simple letter and number indicating the date of production, or a more elaborate bar code or two-dimensional code, which fiber lasers can do. Whether the logo is a single line, outline, or fill font - whatever you want, as long as you can represent it on paper, the fiber laser can copy it to the metal. Some labels are subtle, such as functional labels that are often used as scales on a variety of tools or instruments. Some marks are not very important, such as decorations or decorations, fiber laser can also be marked.
The volume of Otlaser laser marking machine supplier provide fiber laser for stainless steel is only as large as the shoe box, but it can provide 10-40mw focused nanosecond pulse. When marking, it can change the color of the material surface without the influence of heat and form a permanent mark. Combined with optical scanning vibroscope, any pattern can be printed, making it a widely used marking tool.
The physical and chemical properties of stainless steel and its reaction to laser light are worth studying, because the final visual effect may be completely different depending on the characteristics of the incident light and the grade of stainless steel.
High power laser cutting equipment will cause partial melting of the metal surface. The melting part will produce a series of pits and react with oxygen in the environment to become dark marks, and the contour can be touched to have a concave and convex feeling. With the increase of pulse energy, some materials are vaporized and pressure is generated at the cavity melting point, which results in splash effect and greatly improves the visual quality of the marking. After repeated marking back and forth for many times, the carving effect can be obtained.
Low power laser cutting machine have a completely different effect: they can produce dark black marks without melting the metal, which is commonly referred to in industry as annealing marking (a name not recognized by metallurgists). In fact, this should be called black oxidation marking, it has a very high contrast, but it does not affect the surface roughness or texture of the material. Such labeling is widely used in the field of consumer goods. More interesting, though, may be its use in surgical instruments. Surgical instruments are the most stringent in terms of labeling quality, because they must be treated with multiple sterilization procedures without quality degradation or local rust. This is a serious challenge and requires very careful control of pulse conditions and heat input. The flexibility and controllability of fiber laser pulses make them ideal for such applications.
