In terms of methods, there are several ways to realize it: laser, acid etching, cnc (mechanical), sandblasting, hand-carved pen, pure hand-carved knife (this can only be done by a master, and it is estimated that the products made are not for ordinary people, but handicrafts), and there is also frosting (this is not carved in, but it is very similar to laser carving on glass).
Moreover, red wine carvings are all glass carvings. Of course, there are few red wines made of crystal bottles. This is a special case. There are many materials in the packaging containers of Chinese liquor, so I won't go into details here.
Red wine carving methods include laser, acid etching, cnc (mechanical), sandblasting, hand carving pen, hand carving knife carving and frosting. Let me explain the advantages and disadvantages of various carving methods.
1, pure hand carving knife: this has been explained before, so it is impossible to make a hand carving knife on a wine bottle for production and processing, unless it is used on the so-called 82-year Lafite, and it is generally impossible to use this method for red wine below 5,000 yuan. It's made by craftsmen, and it takes a lot of man-hours to carve a complete bottle of wine, plus the labor cost of craftsmen, which is beyond our capacity.
2. Hand-carved pen (Taobao has 50-200 yuan's): This pen is a high-speed (20,000 rpm) rotating head, carving on the glass, which is controlled by human hands, so it is difficult to control unless it is a professional artist, and this kind of carving can't be fine. Can only do some diy entertainment.
3.cnc engraving machine: CNC is a very common mechanical engraving machine. Simply put, the manual engraving pen is not controlled by human, but by xyz axis. The price ranges from 4,000 yuan to100,000 yuan, but when it is used for red wine bottle carving, a rotating aid must be added (extra purchase, generally domestic technology is not very good). The best one is French M40G(M40 is about 60,000-70,000, and M40G is between10-10,000, which is the price of 20 12 years, but I don't know now). The engraving effect of this engraving machine is very good, basically fully automatic, with little manual participation. But the disadvantages are high price and low efficiency (basically, a bottle of wine with 23cm* 15cm needs more than 1 hour, and it will take longer if the pattern is complicated). What's more, it handles characters very well, but for pattern making, you need to learn a relatively cold software Type3 (it seems that the software price is 60,000-70,000, and it has not been cracked online), which is not very easy to learn.
4. Acid etching: it is relatively rare at present, that is, the place to be etched by acid is isolated with a template, and the place to be carved is in contact with acid. The main acid etching is hydrofluoric acid. It is very dangerous to corrode the glass surface with hydrofluoric acid and other substances, which will hurt people's skin and even bones, and the volatile gas is toxic and corrosive, which is easy to hurt the respiratory tract. If it is used to carve red wine, it is basically useless. What do you think of the disposal of used acid? In the bathroom and kitchen? You'll hurt the sewer. The key is that you can't buy this thing, and society stresses harmony.
5, frosting: This is not deep, it is to use frosting paste to contact the glass that needs to be carved. After a specified time, it is cleaned with water, and the patterns and characters you designed appear on the surface of the glass. The key is that there is no depth and it is not easy to be colored. Much like screen printing. To be exact, this is not a sculpture.
6, laser carving: Many people think that red wine carving is laser carving, in fact, this is a big misunderstanding. Laser engraving on glass has not been very good, which is related to the working principle of laser. Laser vaporizes glass through instantaneous (very fast) high temperature (very high temperature, which can ablate metal), so there is a lot of glass dust on the laser head after laser engraving glass. However, when laser carves glass, the glass will be frosted, and the glass that should not be vaporized will be vaporized under the magnifying glass. The glass carved by laser has basically no depth (the author carved it in the same place for ten times with an imported laser machine, which is a bit deep, but it is terrible). In fact, laser engraving has another feature that many people don't know: the cheaper the glass, the better the engraving effect, hehe. The reason is that there are many kinds of glass itself, such as lead content and so on.
7, sandblasting carving: Having said that, everyone basically knows that red wine carving is sandblasting carving. Sand blasting glass carving is a very old technology. You can go to Baidu to learn about the history of sandblasting. Its advantages are high speed, deep depth and high relative accuracy, but its disadvantages are high noise, pollution and high air pressure in working principle, which may be dangerous.
Red wine carving, parting carving and automatic carving have their own advantages. Let's start with hand sandblasting carving. Manual sandblasting is famous for its name. It's hand-held spray gun sandblasting carving. Manual sandblasting can be aimed at some parts of sandblasting, resulting in different shades, relief effect and stronger three-dimensional effect. But it takes practice, and not everyone can grasp it well. If you are not careful, you may ruin a work. Irrevocable! Another disadvantage is that people must always operate the operation box. If the dust control of the operation box is not good, a large amount of sand blasting materials such as diamond sand, white corundum and broken glass powder will be sprayed out of the operation box, which is very harmful for people to inhale such dust. Another disadvantage is that it tests the human body, waist, hands and joints. Working like this for a long time will definitely have an impact on your health. It is absolutely not advisable to exchange health for money.
Generally speaking, automatic sandblasting is not numerically controlled, so it is difficult to carve the relief effect. Generally, it is flat spray. Spray evenly and the depth is consistent. For people, there is no need to operate on the operation box, so as to avoid inhaling harmful substances such as dust. People don't have to manually operate the spray gun for a long time, which is also a kind of liberation for people. Long-term wine bottle carving, like the factory, uses automatic sandblasting. High efficiency. It is good for people's health. Automatic red wine engraving machine has extremely low failure rate and consistent depth. General manufacturers will train how to use machines, how to color and how to choose materials. Because of professionalism, more valuable trust, follow-up maintenance and upgrading are guaranteed, the red wine carving process is basically the same, the same principle, the same process, the difference is design! Depth! Accuracy! There are two kinds of designs, one is generated by software, and the other is hand-painted, which is very popular with customers. Of course, the depth is controlled by the length of sandblasting time, and manual sandblasting is to keep moving the spray gun back and forth to control the spray gun to move back and forth and carve on the pattern (manual work is very tiring, and vision and figure are both tests). Generally speaking, there are many reasons for precision control, the material has the greatest influence, followed by the influence of process treatment. Now the automatic sandblasting machine, manufacturers will deal with this series of problems very well. It is best to choose the automatic sandblasting machine for entry, and everything is guaranteed. Training is generally free, (some people teach this craft online for almost 20 thousand yuan, and this craft basically knows how to operate in related industries). Many people know about sandblasting carving, but few people know about bottle carving machine. Because there are too few users, it is only used in a small range. Many users in the industry have entered the automatic bottle engraving machine, and most practitioners in the market spray by hand. A day's output is small, people are tired, the noise is loud, it is difficult to mass-produce, and the quality is difficult to compare with the automatic sandblasting engraving machine. The bottles carved by automatic sandblasting machine have the same depth, strong stereoscopic effect and controllable depth. If you want to operate the spray gun manually like this, it is definitely a test of technology and whether your physical strength can operate the spray gun manually for a long time.
There are many aspects to consider when choosing a bottle engraving machine. Equipment size, noise level, cost control, recovery system, dust removal system, efficiency, qualified rate and product quality are unified (it is very important to make the same model in batches, and it is difficult to achieve all consistency by manual sandblasting). The best manufacturers can provide one-stop service, from technology to design. A good bottle carving machine should have good control over efficiency and noise. General noise is caused by two parts, the first is the noise of the air compressor, and the second is the dust collection system. Because sandblasting is carried out in a box, there is an exhaust and dust removal part. Generally, high-power vacuum cleaners have several hundred watts, and are equipped with cyclone dust removal system or bag dust removal. This scheme must be equipped with a high-power dust collection power supply! Disadvantages are high noise and unsatisfactory dust removal effect. How noisy is this? Louder than a household vacuum cleaner! If you leave it at home, it will definitely affect your neighbors and your mood. What's more, dust will run out and cannot be completely removed. The real bottle engraving machine adopts the patented dust removal scheme, and does not adopt the industrial high-power dust removal motor, thus ensuring the extremely low dust removal effect. The dust removal effect is very ideal. Please choose a red wine engraving machine, and be sure to consider this. Don't be fooled, good equipment is the first condition of good health, and comparing the market is definitely an old plan to eliminate the backwardness of excellent machines.
The choice of red wine carving is automatic or manual, and there is no basis. If you want to get into the business quickly, use an automatic wine carving machine to get into the business quickly. The equipment can be constantly updated to adapt to different bottle carvings, and the labor, cost and quality are guaranteed. Health is important, efficiency is important, and quality is more important. Automatic wine carving must be the trend.
The key points of sandblasting carving: the selection of spray gun, the selection of pressure, the control of distance between spray gun and object, and the control of direction. If you insist on manual operation, what tools are there? I just want to tell you that it is nothing more than controlling the distance and angle. How fast the efficiency is, the bigger the power of the air compressor is, the faster it is, and the choice of pressure, all of which determine the efficiency, and of course the area to be carved! I'm not fooled into carving hundreds of bottles a day, just a few words, a simple pattern, and 500 bottles will do. The high precision, depth control, smoothness and smoothness of the carved surface of red wine carving can not be handled by hand sandblasting. Moreover, some novices who do red wine carving use hand sand blasting to make the shades different, and the angle problem will lead to the inability to make fine patterns and portraits (portraits are dot maps, and patterns composed of dots can be generated by software). Hand-carved products often produce defective products, the carved surface has stripes, and large-scale yin-yang carving can't be done, but hierarchical carving can.
