Laser marking problems, if not to solve the problem will affect the product delivery time, although marking machine maintenance is too much trouble, but it is relatively simple principle, there are many problems can be resolved and does not require the maintenance of professional and technical personnel, the following is marking five common faults. One. Laser marking logos partially unclear Solution: Check the thickness is uniform molded version, compression pressure is too small, the temperature is too low, if the machine accuracy. Process control points: Molded version thickness error should be controlled to zero. Within O01mm, hardness should be maintained at 230-280N / mm. Because the hologram by embossing roll to exert some pressure and molded the interference fringes, if molded version of the hardness is not enough, in the process of imprinting stress molded version will be deformed or damaged. II. Laser marking logos bleak Solution: Check the heating temperature is too low, if the molding pressure drops. Process control points: Molded pressure setting should be considered a molding temperature, the type or the softening point of the coating layer molded version of the holographic material and other circumstances. Speed ??can be adjusted according to the molded composite imprinting machine quality performance. III. Laser marking logos white Solution: Check whether the speed is too slow molding, mold temperature is too high. IV. Laser marking identification sticky film version Cause: pressing temperature is higher than the degradation temperature increase will cause a sticky adhesive coating edition leaving holographic film wound on the platen roller. Workaround: Reduce hot temperature. Five. Laser marking a clear identification pattern causes a blurred: the uneven distribution of the temperature of hot pressing apparatus or molded version uneven.
