As a garment accessory product, gilding has been widely used at present. Heat transfer printing can also be used as a clothing decoration, there are many kinds of heat transfer printing. 1 Ordinary heat transfer 2 thick plate heat transfer 3 silicone heat transfer. And so on. . Heat transfer can increase the beauty of clothes, increase the value of clothes; But poor quality heat transfer pictures, graphics are easy to move, diamond discoloration, damage, and even fall off, affecting the beauty, reduce the value of clothes, affect the economic benefits and reputation of enterprises. Therefore, Yuan jewelry small make up here to introduce some knowledge of bronzing.

Factors affecting hot stamping: first, hot drill, hot film quality; Second, the quality of hot paper; Three is the forming method; Four is fine processing; Five is the way of packaging; Six is the mode of transport; The seventh method is ironing; Eight is the inspection and acceptance.

One, the influence of hot stamping factors - hot drill, hot piece quality identification

Hot drill and hot piece (octagonal piece, flat piece) quality mainly from four aspects to identify:

One is brightness. Good quality, good brightness; Poor quality, poor brightness.

Second, color difference: high quality, pure color, small color difference; Poor quality, wrong color, big color difference.

Three is the specification: high quality, uniform thickness; Poor quality, uneven thickness, diameter is large and small.

The fourth is the primer: high quality, thin and round primer, consistent color; Poor quality, primer thick irregular, different shades of color, and even a lot of lack of primer. From the ironing effect, good primer is not easy to fall off, poor primer is easy to fall off, especially after touching water will fall off.

At present, there are three kinds of drilling pieces on the market: imported, semi-imported (domestic processing of foreign materials or foreign technology of domestic materials) and domestic drilling pieces. Imported best, semi-imported better, domestic general. Because of the different technical indicators of drill bits produced by different manufacturers, the state has not inspected them, so in the absence of grade standards, manufacturers and dealers will make the quality and price of drill bits in the market confusing according to market comparison, purchase price and business demand.

Two, the reason for the influence of hot drawing - hot paper

There are only two kinds of white hot paper and yellow hot paper on the market, each with its own merits. White hot paper is divided into coarse, medium and fine. Generally speaking, the white hot paper has lines at the bottom, the drill is not easy to move; Yellow hot paper although the glue viscosity is good, but the base paper is smooth, suitable for hot piece. Therefore, according to the hot printing drill to choose hot paper.

Three. Factors affecting the making of bronzing die

Mold making is the key to hot stamping, graphics decision depends on mold making. There are two ways to make molds. One is the production of mechanical drilling machine mold. The disadvantage is that only round drilling pieces can be formed. The accuracy of the graphics depends on the experience of the mold maker. The second is computer laser mold production (computer engraving machine and laser machine), can be made according to the pattern, not bad at all, but the cost is higher.

Four, the influence of bronzing processing factors

Processing is divided into rough processing and finishing, are completed by hand. Rough processing is based on the sample and the general processing of materials, inspection is not detailed; At the same time, attention should be paid to processing quality, serious acceptance, replacement of color difference, damage, lack of glue, wrong drilling, so that the graphics and the effect of the picture. In time, roughing three pieces, finishing up to two pieces.

5. Factors affecting heat map packaging

The outer packing is made of vacuum plastic paper and carton. The inner packing is very important. General newspaper packaging, the number of sheets should be appropriate, the tightness should be moderate. As a result, the thermal image did not fit the drill piece.

Vi. Factors affecting the transmission of the hot spot map

Hot image transportation to special protection, handle lightly, not pressure not play, long distance transportation must be insured

, and take care to ensure that the image does not move.

7. Factors affecting heat map - thermal method

There are many ironing methods for ironing pictures, such as steam ironing, ironing, laser ironing, electric ironing, etc. Generally speaking, a good heat map is mainly an organic combination of temperature, time and pressure. Ironing (octagonal piece, flat piece) melting point is 140°C, so the temperature must reach 140°C to ironing well; Domestic hot drill temperature is low, generally about 140℃; Imported drill requires high temperature, generally 160℃ - 200℃; Low temperature of small diameter bit, high temperature of large diameter bit; It can't be hot, because the temperature of heat is low, so you need to raise the temperature to hot; If the glue is produced, it is because the hot temperature is too high and needs to be reduced. It's just a little warm. The time is generally between 10 and 15 seconds, depending on the circumstances. Depending on the fabric, the pressure should be moderate. In general, heat is heated from hot paper surface, thin material can also be heated from cloth surface (hot plate should not be heated from cloth surface). Thin material temperature should be low, thick material temperature should be high; Flat clothes are easier to iron. Clothes of different thicknesses and drill pieces of different sizes need to be ironed with a stretchy mat and slightly higher pressure. Most notably, steam ironing colored domestic star anise and flat sheets on white clothes can easily stain white clothes, so only use other ironing methods. Because flakes of all colors fade except for the non-fading white and yellow hot film, but they are not visible on colored clothing. Stamping on printing requires that the printing pattern should be left with a small hole in the bit seat for stamping, otherwise the bit will fall off easily.

Viii. Factors affecting bronzing inspection and acceptance

Check before ironing, check after ironing. All heat maps made with drill pieces (including imports) will more or less appear color difference, damage, lack of glue, drill piece positioning, and even the phenomenon of missing drill pieces in the graph. Therefore, the phenomenon of ironing must be checked and corrected before ironing clothes. Acceptance after ironing: First check whether the ironing is good. If there are a lot of diamonds not ironed properly, immediately increase the temperature and pressure when ironing time is extended. Hold another drill with a clamp, place it on a cigarette butt, lighter, or ironing machine to heat the melted glue, then press it directly on the cloth; Second, after ironing, use your fingers to scrape the hot print, moderate strength. If it cannot be scraped off, it is considered hot; If the bit is scraped off, it is not hot and should be reworked.
