Appeared on the domestic laser marking the beginning of the development has been rapid development of Gao to the stage of stable development in the domestic applications are more widely, then seek a new growth point for business development in the field of stainless steel marking expand stainless color dozen new target technology, creating a laser marking of another era. Color laser marking machine with ink deposition techniques as well as those by application of colored powders or films is different, more advanced lasers allow plastic color change with the typical physical effects related to the thermal decomposition reaction occurs with a polymer in an oxygen environment By contrast, the surface of the metal material capable of generating a variety of colors. Color laser marking machine for marking items with high contrast color decorative effect, general color laser marking opportunity by using two laser marking needs to be carried out on plastic, metal and other materials. With the right laser output marking the substrate is to meet user needs in a variety of plastic and metal surface shot in black and white or color imprinting with high contrast. Stainless steel color principle, there are three color ways: First, a colored oxide; the second is through the lower chemical, electrochemical or laser action in a stainless steel surface layer of thin colorless and transparent oxide film, the oxide film to produce interference effect, it can show color in tables; the third is at the same time there is a mixed state of colored oxide and oxide film. Stainless steel laser color marking of the color change and the correspondence between the laser energy, laser effects, laser thermal effect produced stainless steel table. By laser thermal effect obtained firefly laser energy density is proportional to the film thickness. With increasing laser energy, stainless steel sheet and color changes in the following sequence of colors: orange - red - purple - blue - green, blue - blue and green - green - yellow and green - yellow - Cheng - red. Application of PVC material required, PVC material is a non-crystalline vinyl polymeric substance, a substance for which an oxidizing agent, reducing agents and strong acids have a very good endurance. Carbon dioxide laser marking of PVC material displayed yellow red many times is not so popular, and near-infrared laser such as fiber laser marking machine and laser marking machine, they are two kinds of wavelengths around 1060nm, the wavelength but marked black to play, this black and black ink inkjet alike, is a color most allow customers received this type of marking more and more applications in the PVC material a.
