Production process of metal wire mesh
Production process of metal wire mesh
(1) stretching
Screen version of the mesh frame with wooden box, metal box, plastic box, combo box, etc.. The tension and the network, on the net frame with cleaning, the tension and the network can be applied to the manual, mechanical or pneumatic driving mode, the tension and the net of bonding and dressing. The tension and the network requirements of screen tension appropriate, uniform and stable, to avoid wire, cable stayed, respective parallel weft wires.
(2) plate making
The direct method: screen cleaning, coating, photosensitive glue, print developing, revised edition. This method of coating film thickness can be adjusted, time-consuming, combined with strong resistance, easy graphic, sawtooth. Indirect approach: to print, sensitive film developing, film, film, exposing the revised version. This method is complicated, the lines are smooth, the film is not firm, and the resistance is low, and the thickness of the film is constant. The hybrid method: screen cleaning, film, print, developing, revised edition. This method is simple and easy to operate, and the thickness is fixed, the lines are smooth and firm.
(3) screen direct plate making
Laser ablation of direct plate making: first in the metal screen coated screen photoptic gum, using laser burn wear photosensitive layer, graphics and text portion of the mesh transparent, prepress system computer control ablation. This method can only be used for metal mesh. II laser exposure CTP: first screen in coated photoptic gum, prepress system computer control laser image on the screen of the filamentation network version. This method uses a special photographic adhesive, UV light wave range, high price of laser exposure system. Third, inkjet imaging system: first on the screen coated photoptic gum, prepress system computer control ink jet system to resist ink jet to graphic photosensitive layer and total UV exposure. The part of the picture and text is not sensitive, rinse off the sensitive adhesive; the blank part is sensitive to light. This method can be used for general photographic glue, no loss of image details.
