Laser cleaning machine in the sealing industry application is mainly metal gasket production process of stainless steel belt surface oil removal, sealing ring mold surface oil and residual glue cleaning, as well as special sealing material surface modification. Seals are divided into many categories, typically O-ring seals or skeleton oil seals, sealing gaskets. Through the irradiation of laser beam, the oil on the gasket is instantly evaporated and stripped from the metal to achieve the cleaning effect.
Metal winding gasket in the winding machine before the need to stainless steel tape surface attached to the oil film cleaning, the existing process is generally through chemical immersion to carry out surface treatment, laser cleaning in the process of cleaning effect can meet the needs of manufacturers, the application of the difficulties mainly lies in the bandwidth and line speed can not be adapted to the two issues, the general width of the laser cleaning equipment are in the 150-200mm, and the width of stainless steel belt between 1100-1500mm. Width between 1100-1500mm; and steel coil cleaning production beat is too fast, generally more than 10M/min, than the laser cleaning of the adaptive speed of about ten times higher. Our company through independent research and development of ultra-wide laser cleaning equipment can solve the problem of cleaning width adaptation, production line speed process application can be solved, but the current industry program cost is too high need to do further optimization.
Seal ring mold surface oil and adhesive residue cleaning applications, we developed a flat mold laser cleaning equipment, three-dimensional five-axis motion, high degree of freedom, applicable to such as friction industry brake pad molds and sealing industry sealing ring molds and other types of flat molds, can be anti-rust oil removal and many times after the mold cavity surface residue cleaning. It can be equipped with additional shifter to adapt to complex molds, and the cleaning process can be selected to retain the plating layer to protect the cutter pattern and prolong the life of the mold. Compared with sand blasting cleaning, it is not only more environmentally friendly, but also ensures no damage to the cavity and reduces the rate of product defects.
Non-metallic material sealing gasket is another major category in the sealing industry, these products on the band 1064-1080nm fiber laser absorption rate is strong, under normal circumstances will cause damage, not very suitable for process applications (such as pulsed laser action on the surface of the rubber material will cause damage to 10μm or so), but for a few special materials can be used as a means of modification, such as attached to polymethylhydrosiloxane For example, in the case of rubber materials with polymethylhydrosiloxane coating, the surface friction coefficient can be increased to 35mN/m and surface tension to 38dyne/cm or more while removing the coating.
At the same time, laser cleaning in ceramic materials and composite sealing parts of the oxide layer cleaning, punching point hair and other processes have a good performance, in the metal surface sealant removal also has satisfactory results. It can be seen that laser cleaning in the application of different materials because of different laser absorption rate will have different performance, so it can also be used as a small number of special sealing material surface modification of the complementary process.
