Classified metal plate production process, which has several of it? I believe that many people are not very clear, do not understand the process knowledge, in fact, a common metal plate production process there are six kinds are: metal printing plate, plating and electroforming signs, metal signs blasting, thermal transfer metal plate, corrosion metal signs, metal flat sun signs, that these six kinds of common metal plate production process specifically how, then explain to you in detail below:
1) metal printing plate
Metal printing plate is the use of resin-based ink on the plate after the pre-treatment of screen-printing, and then gloss, film and other processes can be made of a variety of exquisite color printing metal plate.
Metal printing plate production technology, is one aspect of printing technology applications. Now, after a variety of screen printing signs have been added on the electronics industry and home appliance products are widely used, especially in the surface of a variety of signs using a new decorative craft, it refined and elegant form, many colorful decorative effect to show in front of people, to improve the value and competitiveness of commodities. In the metal plate production production process, play a decisive role is screen printing plate and substrate before treatment technology and printing and screen printing inks choice points.
2) plating and electroforming signs
Plating and electroforming plate production techniques are:
By screen printing or photographic plate method, the film after, then use plating method, so that the sheet of text and lines by pre-plating, copper, nickel, gold medal heap shaped projections child. It is completed according to the user's requirements and a variety of different patterns of text fonts, the product is durable non-corrosive, not afraid of rain and sun, wear and do not fade. Nice bright color, a clear pattern, the brightness of a variety of electronic products, automobiles, household appliances and other essential body stickers.

3) blasting metal signs
Sandblasting of metal plate production techniques are:
Computer lettering method, the engraved metal plate good sticky sticky, text graphics sandblasting to form a sand surface effect, and then subjected to oxidation treatment so that the metal plate is showing signs of placer gold metal effect.
4) thermal metal plate
Thermal transfer metal plate technology is:
The sheet metal with a surface treatment process generates a special panel, and then you design a color image by way of inkjet printing paper hit the switch, by heating to the anti-metal plate made of metal plate.
Thermal transfer metal plate of the production process:
Base paper handling - print protective layer - print pattern layer - light-emitting layer print - print overlay - printed adhesive layer - drying - packaging.
Thermal transfer metal plate
Corrode metal plate is also called etching plate. The main search using the mask, after etching process processing system to do three steps from the Braille metal plate or a concave metal plate. Corrode metal plate making process:
First: cutting: by drawing (layout size) in size, surrounded by more than plus not less than 5mm burrs. Shears with 720 foot-operated shears, the surface smooth, surrounded by non-Maori.
Second: metal corrosion signs Finish:
(1) mechanical polishing: polishing machine with 2.2-4 kW of mechanical polishing wool, cloth round use motor speed is generally 300-350 2000-3000 revolution / min.
(2) alkali treatment: 10-15% aqueous solution of sodium hydroxide at 65-85 ℃ in the metal plate cook 10-30 seconds, and then washed with water, immersed in 5% of the weight of Ming acid aqueous solution.
(3) powder processing method: using a flat brush dipped in old powder (double pink) version of the child will scrub uniform cross method, in addition to the effect until decontamination face, skin or remove oxygen, and then with a 5% aqueous solution of potassium dichromate Closed.
(4) The drawing processing method: using mechanical or manual drawing methods were brushed metal plate surface treatment, metal surface regeneration to achieve the effect.

6) metal flat sun signs
Metal flat sun signs sun cards mainly use photosensitive way, the film which was dissolved in different colors to make it through the development of methods was significant in the metal plate, so as to achieve a metal plate with a descriptive sense of purpose. Here are a few we often come into contact with the metal flat plate concrete drying process and formula (flat sun signs, the process):
(1) material: wool size requirements are generally larger than the plate size (5mm or more), the board smooth, without potholes.
(2) Pre-treatment: polishing - Several methods such as oxidation - drawing - treatment.
(3) Water closed: will handle good board, through to oil, except after the film can not be quickly immersed in water and exposed to the air.
(4) glue: glue configuration. Plastic: 200-230 grams of water: 1000ml, added photosensitizer (weight casein, ammonium) boiling water and cook for 2 hours to fully dissolve the glue, the temperature dropped to 30-50 ℃ 25-30 grams after glue evenly coated in metal plate, drying stand.
(5) copy: You can use SB750 vacuum type machine photographic copy proofing, light 60-90cm time after 40-80 seconds to take, in warm water 1 minute into the color developing solution for staining.
(6) Gloss: After fully dyed brand, dry it with a brush or spray gun painted with gloss paint (general paint brand with the eyes or free baking gloss paint).
Metal flat sun signs are generally used for interior products, small household appliances and non adverse weather affected equipment. The advantage is plate-making process is simple, fast, timely delivery, defective rate and low fees. The disadvantage is that by the sun and rain, easy to fade, can not do outdoor signs.
Metal plate production process classification and everyone explain here, metal signs in all areas of modern society, the use of more and more widely used in electronic products, home appliances, machinery and consumer products, and other fields. Metal plate mainly in copper, iron, aluminum, zinc alloy, pewter and other raw materials for the foundation, made by stamping, casting, etching, printing, enamel, imitation enamel, paint and other craft.
