The use of hot map hot drilling is more common, usually in the garment factory, shoes and hats factory, jewelry factory, handbags factory will use some hot map hot drilling process to decorate their products. Hot figure drilling technology as a popular fashion accessories, can add beauty to the clothing, thus providing the added value of your product; but poor quality, hot map hot drilling figure walk, hot drilling and other materials, hot drilling and other materials discoloration, damage, and even more Severe shedding, thus affecting the aesthetics, depreciate your products (clothing clothing, etc.) and affect the economic efficiency and reputation of the company.
Affect the hot map elements: 1, hot map drilling hot drilling material quality (such as hot drilling, hot film, acrylic, semi-circular pearl); 2, the quality of hot paper; 3, the method of molding; 4, the processing of fine; , packaging and transportation methods; 6, hot map ironing; 7, inspection and acceptance.
1, hot map drilling hot drilling material quality identification
Take the quality of hot drilling, hot film (octagonal film, flat film) as an example, mainly from four aspects to identify:
Brightness: Good quality, good brightness; poor quality, poor brightness.
Chromatic aberration: pure color, pure color, small color; poor quality, color is not correct, large color difference.
Specifications: Excellent thickness, consistent diameter, poor quality, uneven thickness, large and small diameters.
Bottom glue: The quality of the bottom rubber is thin and round, and the colors are the same; the poor bottom glue is thick and irregular, the colors are deep and shallow, and there are even many missing glue. From the results of the finished ironing, the end of the plastic is not easy to fall off, the bottom of the glue is easy to fall off, especially after seeing the water, touch it off.
At present, the market has imported, imported imitation (domestic processing of foreign materials or domestic materials foreign technology), the best import, imitation of imports better, domestic general. Because the production technology indicators of major manufacturers are not the same, the country does not have inspection standards, so in the absence of standard levels, the manufacturers, distributors, according to market comparisons, purchase prices, business needs, self-affixed grade labels, The quality and price of the drill in the market are confusing and difficult to identify. With its many years of market experience and good raw material supply channels, the company has always been very stable in quality and price.
2, hot paper
At present, there are only two kinds of white hot paper and yellow hot paper on the market, each with its own advantages. White ironing paper is divided into rough lines, middle lines and fine lines. In general, white scalding paper has a pattern at the bottom, which makes the drill piece less likely to go. However, the yellow scalding paper has a good viscosity, but the bottom paper is relatively smooth and suitable for scalding. Therefore, according to hot map drill piece to select hot paper.
3, model making and printing
Model making is the key to hot map drilling, and it is determined that the pattern is based on model making. There are two methods of molding, one is the mechanical drilling machine tooling, the disadvantage is that only the circular drill bit molding, graphics accuracy depends on the modeler's experience. The second is the computer laser molding (computer engraving machine and laser machine), can be made according to the pattern of the template is not bad, Amy Schwarz hot drilling processing factory is to use a laser template.
4, hot map processing
The roughing and fine processing of the processing points are all done by hand. Roughing is based on incoming samples for general processing, inspection is not detailed; while finishing is to pay attention to processing quality, careful inspection and acceptance, replacement of chrominance, damage, lack of plastic, shifting drill, so that the graphics to maintain and effect The same picture. Use time to calculate, roughing three pictures, finishing up to two.
5, packaging and transportation
Outsourcing is equipped with vacuum plastic paper packaging and carton packaging. The inner packaging is critical. It is generally packed with newspapers. The number of sheets should be appropriate. The tightness should be moderate. The long-distance transport packaging should be clamped with stiff paper or wrapped in cardboard around the four corners. Hot map hot drilling patterns do not take a bit.
Hot map transport should be specially protected, gently and gently, do not press or hit, long-distance transport should be insurance, be careful to ensure that the hot map hot drilling figure does not take place.
6, hot map ironing processing
Hot map useful steam, hot machine, laser, electric iron hot and other hot methods. In general, hot pictures are mainly organic combinations of temperature, time, and pressure. Hot film (octagonal film, flat film) melting point at 140 °C, therefore, the temperature must reach 140 °C to be hot well; domestic hot drilling temperature is low, generally around 140 °C; import drilling temperature requirements are high, generally 160 °C -200 °C; small diameter drill temperature is low, large diameter drill temperature is high; not hot, because the hot temperature is low, to increase the temperature can be hot; glue is hot, it is because the hot temperature is too high, to lower Point temperature. The time is generally 10 seconds - 15 seconds is appropriate, according to the specific circumstances. The pressure should be moderate, depending on the fabric. Under normal circumstances from the hot paper surface heating, thin material can also be heated from the fabric surface (hot sheet should not be hot from the fabric surface). The temperature of the thin material should be lower, the thick material temperature should be higher, the flat clothes should be hot, and the clothes of different thicknesses and different sizes should use a good elastic cushion. The pressure is a little bigger and can be hot. The most noteworthy thing is that hot, colored Chinese-made octagonal tablets and flats made of steam on white clothes are easy to dye white clothes and can only be changed to other hot methods. Because except for the white and yellow hot plates, the other color plates are faded, but they are not visible on the colored clothes. Hot print on the print request print design should be in the drill bit hole to be hot, otherwise the drill piece is easy to fall.
7, check and acceptance
Examine before hot, hot after acceptance. All the drills (including the imported ones) will have more or less chromatic aberrations, broken, missing glue, missing bits, and even lack of drill holes in the pattern. Before it must be checked and corrected, it will be hot on the cloth. After the end of hot acceptance: First, look at the hot is not good, if there is more than a piece of diamond pieces is not hot, immediately increase the temperature, extend the hot, increase the pressure re-hot once just fine; if there is not a single good hot The drill piece, replace the drill piece with a clip, place it on a cigarette butt, on a lighter or on a hot machine to warm the melted glue, directly on the cloth, and press it once; the second is to use the finger after use. Moderate force scrapes on the hot map. If it cannot be scraped, the drill piece is considered hot. If the drill piece is scraped off, it means that it is not hot and should be reworked.
