Plating and electroforming signs
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
5) etching metal signs
???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.
Stainless steel metal corrosion signs
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):
