Etching and electroplating method of the former film thicker, but the lines of lower quality; the latter film thin lines of good quality and, therefore, mixed using a combination of both, the process is: metal base ( copper) → both sides of the coated photosensitive film → images were drying → both sides both sides of the developing → Plating → Custom Flags And Poles stripped version of the base of the photoreceptor membrane → metal corrosion → template framework.
⑤ laser method to manufacture the metal diaphragm. CAD (computer aided design), the popularity of CAM (computer-aided production) and laser devices improve the functions of the metal model of manufacturing and production of precision parts, mining laser
According to the CAD precision graphic design, computer and software to quickly create high precision diaphragm, this is a big plus, secret so as not to worry about error and both sides of the etched diaphragm movement due to the single-sided etching can be made of fine metal diaphragm.
(6) combined machining of metals and metal film. Metals and metal film and the use of polyester and stainless steel, good elasticity, soft retractable when the of the important surfaces and openings. Metals and friends on the aluminum frame, steel in metal wire and metal film around set aside more than white, more than the white part, Table Flags For Sale adhesive laminating polyester and stretch in the box. Very soft polyester part of the available solvent resistance of the resin to fill the hole, this bonding process called composite processing, plays an important role in the high-density high-precision . Custom Flags And Poles Part of the version of the film around the polyester from the width of the box, such as not enough, it will affect the tension and elasticity when the must be given the appropriate width. In addition, in the case of very high positional accuracy requirements, it is necessary to determine whether only beginning scraper moving side of the metal and the metal film directly bonded fixed frame or aluminum frame, connected with a thin metal plate to increase the strength.
Metal to the formation of the image, Hand Waving Flags For Sale and image formation resin photosensitive film, the intersection of intensity images and the formation of nickel foil of stainless steel metal wire with nickel plated fixed very good, especially in mixed processing, the network is fixed in the box , the cumulative size of a very high precision.
⑦ rotary plate method. Rotary screen method of rotation of the printed version of the tubular in the substrates. Custom Flags And Poles The substrates of the rotary screen leaflets and reel. The latter's on unwinding, take roll and tape tension adjustment device.
The heart of the portion of the rotary screen is the cylindrical plates, printed version of the cylindricity, dimensional stability, plate thickness and through-hole uniformity and other high precision. The basic manufacturing methods for rotary screen version of the electronic plate and adhesive sheet multi-version method. The former applies to the of continuous images, Mini Flags Wholesale of course, there are certain restrictions for the number of mesh openings rate, there are certain difficulties to restore the subtle images. Lithographic features, which can be arbitrarily chosen mesh and open porosity, of course, not suitable for continuous pattern .
3. Photosensitive plate method. Plate method of high quality, Custom Flags And Poles economical and practical, so this plate method is a modern main plate.
The photographic plate method is the use of the photochemical change of the light-sensitive adhesive (film), that is sensitive adhesive (film) by the light part of the hardening of the cross-linked and combine to form a stencil film with solid, light-sensitive part by water or other developer rinse developing form through-hole made of the printed version.
