Signage is one of the most common products in modern society, it is a marker, widely used in the field of home appliances, machinery, civilian products. Them in a variety of sign making, metal labels up one, so this article is mainly to do a brief analysis of the production process for metal signs, so that a deeper knowledge and understanding of the signs craftsmanship.
   What is the metal plate? First, it is a marker, mainly copper, iron, aluminum, zinc alloy, pewter and other raw materials, through the process of stamping, die-casting, etching, printing, enamel, imitation enamel paint, made into a nameplate, badge, badge, medals, key chains, badges, medals, craft signs, cufflinks, mobile phone strap, tie clips, belt head, bottle opener, craft jewelry or metal signs and other products. Common metal flat cast nameplate, metal thermal transfer signs with metal sandblasting signs and other sun signs, metal screen printing signs, signs of metal corrosion, metal plating and metal electric type.

   The design of the signs is the first step in plate production. The signs design is the basis of sign making, requires the designer to design the Figure, is not only beautiful, but also suitable for the production of the following process. General software design such as CorelDraw or AI do mapping software, make plans to customers, we must pay attention to the specific requirements of the customer's size, shading, content, and good pictures to the customer to confirm to start production. Good design drawings, and then a film piece. Films generally send a professional to film companies, they use laser printing, exposure, significant fixing other processes. The thing we need to do is take back the Films check carefully to see and the originals are the same, whether another Films clean and thorough, very clear lines the edge. Then the next feeding, signs copper, stainless steel, aluminum and other metal materials generally, the characteristics of each material is not the same, choose the right materials for signage specific requirements. Choose the right material, such as stamping or cut. If you do stainless steel plate, according to the design of a good size, selected stainless steel plate, on each side are placed on the margin of a few millimeters, marked point cut, cut good stainless steel plate four sides often burr use rasp ground off it the filing after touch, smooth edges, you can.

   Following a brief look at the common sign production process, its steps and methods.

   First, the etching. Etching is one of the most commonly used in a process of sign making. Its main principle is: the first in its metal surface uniformly coated with a layer of corrosion-resistant photosensitive ink put on top of a film backsheet, exposed with ultraviolet light, through the transparent part of the ultraviolet light on the film backsheet from a chemical reaction with the photosensitive ink, forming the anti-weakly alkaline coating film below the black portion of the photosensitive inks intolerant weak base. Naqu film, paper, metal plate is soaked in a weak alkaline solution of sodium carbonate, intolerant weak base portion of the coating will chemically react with the sodium carbonate solution while shedding, those places the metal is exposed out, the metal plate on will be showing a pattern. Affixed a layer of the corrosion protection film at its opposite, put it into the etching machine, the trivalent iron ions in the exposed washed with ferric chloride solution with the surface of the metal plate, the ferric chloride solution is rapidly oxidized, etched This part of the metal plate, so that the partial metal plate is etched down. Would also like to emphasize that the etching process, in addition to the sign making single-sided etching can also be double-sided hollow etching. This is very common in the handicraft production.

   Second, the plating. Most signage surface treatment process is a plating. Electroplating means with the DC, so that a metal semi-finished products is carried out in solution electrolysis reaction, thereby evenly on its surface, accompanied by a thin layer of another metal or alloy. Now that local governments provide, the plating only by professional plating company. For plating, nickel plated (silver), copper (including plated bronze, copper color, etc.), gold-plated (including plated with real gold plating K gold plated imitation gold). Plating part, a more detailed description of our other articles.

   Third, the color of signs. Signage color commonly used electrophoresis coloring process, cathodic electrodeposition coating with color color machine. Following example black.

   Color before the anode connected to the conductive plates of cathode connected to the protective film gap in the middle of the signage semi-finished to ensure signage semi-finished conductive normal. Conductive Insulation folder at hand then use signage semi-finished products on the cathodic electrodeposition coating of black, open with power, the time is set to 40 seconds, the time to color automatically after power failure, signs of color on Shanghao. Water excess floating color rinse, placed in an oven, the temperature is set to 88 degrees, and heated for 20 minutes, cured film. At the same time, signs of solid sodium hydroxide is added in a clean container, lust on the signage on top, adding hot water of about 80 degrees and then a ratio of 1:10, swing container, fully dissolved in the sodium hydroxide solid The photosensitive film left after the semi-finished etching will slowly corrode go. Wobble after half a minute, remove the signs, and washed with water remaining on the surface of the etching solution. Black-and-white signs in natural drying, cut a good side, they can become a window of the product if we do two of the same piece of film, and then the two faces are coated with resistance to corrosion photosensitive ink metal plate inserted in the middle, KR-B2-sided vacuum exposure machine in two faces exposed at the same time, up and down at the same time etching etching machine, slightly longer time, the metal plate will be engraved wear. Will be able to make such exquisite handicrafts.

   These are just a brief introduction of the plate production process, in actual operation, but also applied to many other production process, here is not introduced. Other articles in Hua Lung Metal inside, you can also get to know some other process on the inside.
