What is the process of hot stamping, hot surface process

Hot stamping, commonly known as"Foil stamping"It has a good development and application in China. The following carton packaging printing will give you a detailed introduction to the hot stamping process.

Hot stamping refers to the printing of words and patterns of colored foil and other materials on the first or fourth cover of the hardcover book cover and the back part of the book, or the embossing of various convex and concave book titles or patterns by hot pressing method.

Hot stamping refers to the processing of hot stamping materials or hot stamping patterns on paper, cardboard, fabrics, coatings and other objects by hot stamping method. The hot stamping of binding is generally more on the cover, and its forms are various, such as hot stamping of a single material, hot stamping without hot stamping, mixed hot stamping, set ironing, etc.

Hot stamping is an important means of surface decoration of plastic parts, and it is also a commonly used decoration process for household appliances and consumer electronic products. It is a hot stamping head that is heated to laminate the metal or paint on the hot stamping film to the surface of the workpiece to be processed to achieve the purpose of decoration or logo. There are four basic conditions for the hot stamping process:

The hot stamping head consists of a hot stamping plate, a heater, and a pressure transfer mechanism.

The hot stamping film is to determine the color, ** and other decorative effects, and there is a film conveying and winding device on the equipment. Hot stamping fixtures (fetal tools, cushion heads) include workbenches and conveyors. There are flat ironing and piping hot stamping methods.

Flat ironing includes small arc curved surfaces, folded surfaces and inclined surface ironing, and its basic forms are "flat ironing" and "round ironing"; Boiling hot includes flat ironing, circumferential ironing and non-round surface peripheral ironing, and its basic forms have two types: "flat ironing" and "round ironing".

In the fierce market competition, in order to increase the added value of products and more effectively carry out packaging anti-counterfeiting, more and more packaging cartons adopt hot stamping process. Hot stamping is divided into ordinary hot stamping, cold hot stamping, concave and convex hot stamping and holographic hot stamping.

The commonly used ordinary hot stamping process includes flat hot stamping and circular hot stamping, in which circular flat hot stamping is a line contact method, which has the characteristics of a wide range of hot stamping substrates, suitable for large-area hot stamping, and high hot stamping accuracy.

Instead of using a heated metal plate, cold stamping uses a printing adhesive to transfer the metal foil. The cold stamping process has low cost, energy saving and high production efficiency, which is a promising new process.

Concave and convex hot stamping (also known as three-dimensional hot stamping) is the use of modern engraving technology to make the upper and lower matching of the female mold and male mold, hot stamping and pressing concave and convex process to complete at one time, improve the production efficiency. The mold made by electric engraving can achieve the three-dimensional relief effect that cannot be achieved by the mold made by the general corrosion method through the curved surface transition. The emergence of embossing and embossing hot stamping makes the hot stamping and embossing process complete at the same time, reducing the process and the waste caused by inaccurate overprinting.

Holographic logo hot stamping uses computer technology to change the amplitude and frequency of the grating, so that its effect is more brilliant and clearer than the calculated pattern color. If this holographic logo is used as the original copy, a large number of holograms will be lost, which can achieve the purpose of anti-counterfeiting. The holographic logo can not only have very good anti-counterfeiting performance, but also can be used in the holographic logo according to the needs of customers, and is more and more widely used in high-end carton packaging.

First, the way is different.

1. Silk screen printing: refers to the use of silk screen as the plate base, and through the photosensitive plate-making method, the silk screen printing plate with ** is made.

2. Hot stamping: refers to the words and patterns of colored foil and other materials on the first or fourth cover of the hardcover book cover and the back part of the book, or the hot pressing method is used to emboss various convex and concave book titles or patterns.

Second, the printing method is different.

1. Fiber silk old auspicious seal: screen printing is composed of five elements, screen printing plate, scraper, ink, printing and printing materials. When printing, ink is poured at one end of the screen printing plate, and a certain pressure is applied to the ink part on the screen printing plate with a scraper, and at the same time it moves at a uniform speed towards the other end of the screen printing plate, and the ink is squeezed onto the substrate by the scraper from the mesh of the ** part during the movement.

2. Hot stamping: The heated hot stamping head will laminate the metal or paint on the hot stamping film to the surface of the processed workpiece to achieve the purpose of decoration or signing. There are four basic conditions for the hot stamping process: the hot stamping head includes a hot stamping plate, a heater, and a pressure transmission mechanism.

Third, the principle is different.

1. Silk screen printing: the basic principle of using the screen printing plate is partially perforated with ink, and the non-part of the mesh is impermeable to ink.

2. Hot stamping: It is the process of transferring the pattern on the anodized aluminum to the substrate through the action of heat and pressure. When the printing plate heats up to a certain extent with the attached electric heating plate, it is embossed through the anodized aluminum film and the paper, and the adhesive layer, metallic aluminum layer and color layer attached to the polyester film are transferred to the paper by using the action of temperature and pressure.

The structure of hot stamping is: hot stamping (upper and lower structure) printing (left and right structure).

The structure of hot stamping is: hot stamping (upper and lower structure) printing (left and right structure). The phonetic pronunciation is: 一 . Pinyin is: tàngyìn.

My hometown is in the northern part of Anhui, a typical Great Plains region. As far as the eye can see, it is all plains and land, and not even a small hill can be seen. When I came to the university, my classmates came from all over the world and from all provinces, so we had a common topic, that is, the specialties of our hometowns, what are they?

You are what I thought about and thought about, and I didn't think that there were any specialties in the Huaibei Plain.

That week, I made a special call to my family and asked what specialties our hometown had. My mother disdainfully said, "Where is there any specialty in the Huaibei Great Plains, if you want to say that there is really a special feature of food, that is, hot noodles." Then I asked, "What is the production process?"

said a word, and if he wanted to go, he hurriedly hung up Qibu**.

So I started trying to remember the process of making the noodle soup.

First prepare a scoop of noodles and a bowl of water, mix the noodles and water together properly and evenly to form a dough, and then use a rolling pin to flatten the dough. If the craftsmanship is good, the noodles of Taiping must have a little arc. Because it is beautiful and beautiful enough to be scalded in this way, it makes people have a great appetite.

The second is to prepare a large stove, stew the soup stock on the stove with a pot rack, wait until the soup is boiled, put the noodles in the pot with a colander and cook for one to two minutes, then scoop them up, put them in a bowl and add two spoons of soup with a spoon, and then put the dosage according to the preferences of different people. For example, some people like to eat spicy, just put a little more chili, some people like to be jealous, put a little vinegar in the sedan chair, completely according to personal preferences to put coriander, green onions, minced garlic, so that a bowl of fragrant hot noodles will be out of the pot. Do you feel like you want to try it?

Then come to my big Huaibei to ensure that you have enough to eat!

When I went to university, I realized that sometimes I actually thought like this, my hometown is like my hometown noodle soup, and I am in a foreign land, and the love of family is getting stronger and stronger. Now I just want to have an urge to go home, and my Dahuai Beida Tang Noodles Spring Festival is waiting for me.

The process of hot stamping is mainly divided into seven parts: preparation before hot stamping, plate mounting, pad plate, determination of hot stamping process parameters, test ironing, sample signing, and formal hot stamping.

Hot stamped clothes:

1.Preparation before hot stamping: inspection and selection of anodized aluminum.

In addition to the selection of the correct anodized aluminum, we should also pay attention to the quality characteristics of anodized aluminum raw materials, because the quality of anodized aluminum materials directly affects the grade of the product. Hot stamping plate preparation. There are generally three types of hot stamping anodized aluminum plates: copper plate, zinc plate and copper-zinc plated plate.

It is better to use the copper plate, because the copper plate has strong heat resistance, has a certain elasticity, is more durable than other plates, and has a good hot stamping effect.

2.Plate mounting: Install the prepared copper plate on the bottom plate, then firmly fix the bottom plate on the electric hot plate of the machine, and then adjust the rules and pressure to the appropriate process.

3.Pad: According to the hot stamping effect, the pad plate is treated for local unevenness and unfavorable hot stamping effect, so that the pressure is uniform everywhere.

4.Determination of hot stamping process parameters: hot stamping temperature.

The hot stamping temperature is determined according to the texture of the hot stamped object and the hot stamping form (such as plastic, paper, leather, etc.). The general settings are as follows: Plate temperature:

100～150℃；Machine temperature: 70 200 . Hot stamping pressure.

The size of the hot stamping pressure should be determined according to the nature, thickness and hot stamping form of the hot stamping object, which is larger than the general printing pressure. The pressure is so great that it is not pasted, and the scalding marks are clear and bright; Its pressure is so small that it is firm and does not fall off and does not bloom. Time for hot stamping.

In practice, the hot stamping time is usually regarded as a constant, and it is not easily changed. After fixing the hot stamping time, adjusting the hot stamping temperature and pressure will reduce the variables, simplify the operation, and make it easier to control the quality.

5.Test ironing: After the current work is ready, you can test the ironing of several sheets, if the rules are not right, you can adjust the front gauge or side gauge appropriately; If it is because the quality requirements are not met, the hot stamping temperature can be adjusted again or the pad plate operation can be carried out, and after the requirements of the hot stamping quality regulations are met, you can take the test hot stamping sample and the standard original to the workshop supervisor for sample signing production.

6.Signing: The workshop supervisor confirms the qualified hot stamping after repeated comparisons, and after signing the sample, the operator carries out the formal hot stamping.

7.Formal hot stamping production: In the formal production process, the operator should conduct self-inspection according to the production requirements, and the workshop supervisor and quality inspection personnel will also conduct spot checks and inspections on the side of the machine.
