What is the concept of acrylic blister?

Preface: acrylic light boxes and craft products by virtue of its bright colors and good easy to form, good toughness, high light transmission and other physical properties, by the majority of commercial customers. Especially with the geometric growth of the domestic acrylic products market, many of the conditions of the traditional advertising products companies have introduced acrylic suction molding equipment, or to achieve a one-time transition to the acrylic products company. However, according to the author of the first-hand information on market sales, summed up the acrylic equipment market sales in the existence of two fundamental phenomena: First, many companies want to buy acrylic equipment do not know what acrylic materials, not to mention what is acrylic suction molding equipment; Second, many companies just entered the industry do not understand the acrylic equipment, in particular, do not know how to select the right for their own use of the Equipment, and therefore often rely on their own self-righteous feeling to buy. As a result, often just buy home on the regret, wrong, it is not what I need, or simply can not meet their needs. To this end, the author based on the above issues, the formation of this article, are interested in the development of the acrylic industry to allow customers to choose to buy back suitable for their needs, and try to avoid the phenomenon of consumers buy home on the regret. Here, the author states that this article mentions all the acrylic equipment manufacturers with the text or information, there is no denigration or slander, if there is inappropriate, please understand, and this article represents only the author's personal views, and the views of Nanjing Bia enterprises have nothing to do. First, the basic composition of acrylic suction molding equipment Currently in mainland China market common acrylic suction molding machine, from the industry, there are two major categories: the first is used in the bathroom industry bathtub commonly used suction molding machine; the second is the advertising products industry commonly used suction molding machine. Although the two molding principle is exactly the same, but the size, function, cost is a world of difference, so this article is only commonly used in the advertising industry suction molding machine is the main, although the end of 2004, Nanjing Bia company will be the introduction of German technology to produce a new generation of products can be used in the advertising industry at the same time can be used in the production of sanitary ware, but after all, it is still an afterthought. 1, acrylic suction molding machine system composition advertising products industry commonly used acrylic suction press, from the system, is divided into acrylic heating and softening system, acrylic pressure molding system, acrylic suction molding system of three major functional systems, the domestic famous acrylic suction molding machine producers in Nanjing Bia and the addition of acrylic blowing molding system, into the four major functional systems. Here to apply the famous Guangzhou acrylic products business Chen Yangchao general manager of a sentence: "acrylic only with suction, pressure, blowing three means to create a variety of modeling products, otherwise, the performance of the acrylic sheet can not be fully realized." 2, the structure of the acrylic suction molding machine form At present, the domestic acrylic suction press structure *** there are three kinds: the first is to Nanjing BY as the representative of the split, that is, the pressurized softening system is divided into suction, pressure, blowing the system separately of the two-body type; the second is the heating, suction, pressure of the function of each for the integration of one body type; the third is the Northeast x x x classic type, Shandong x x x, Hebei x x x, and so on, as the representative of the heating, suction pressure molding system Separate and connected to the one-piece type. Of course, at present, the major domestic manufacturers have split, one-piece and other models for sale, which mainly stems from the needs of different customers, of course, each model has its own advantages and disadvantages, and Northeast × × × ×, Shandong × × ×, etc. had launched the one-piece, can be considered between the split and one of the transition between the product, certainly advantages and disadvantages are also between the two. 3, acrylic suction press working form acrylic suction molding machine working form, and is divided into two kinds: the first is to Nanjing BY-X2 type, BY-X4 type, Shandong × × ×, Northeast × × × series, Hebei × ×, etc. as represented by the lower pressure type from above; the second is the Northeast × × × series, etc., as represented by the top type from the bottom into the top, of course, the families say that their own design is the most scientific, but from the use of the Function, production effect, there is no essential difference, only the operating habits and the degree of ease of operation. 4, acrylic suction molding machine platform lifting mode: on the domestic market suction molding machine platform lifting mode, the major manufacturers basically use the green hydraulic lifting system, only Qingdao × × electric control lifting system, as for the difference between the two, the reader can distinguish between the two according to their own experience and basic knowledge, if the specific instructions, probably lies in the hydraulic pressure with elasticity, and electric control may be elasticity Poor, because the author himself has not used such electronic control equipment dare not make wild statements. In addition, in the market, there are many businesses talk about whether the method of air pressure can be used, can be sure to answer, air pressure is too strong elasticity, it is difficult to apply to the acrylic pressure molding system, this is due to the physical properties of acrylic sheet decision, that is to say, it is difficult to reach the pressure of acrylic required by the stability of the pressure, so there is no need to make such assumptions. Second, the functional application of acrylic suction molding machine systems outside the industry or just stepped into the acrylic industry customers, there is often a kind of puzzled question: why the same are called acrylic suction molding machine, and the price difference from more than 10,000 yuan to more than 100,000 yuan are, is the producer of the industry profiteering or the difference in the performance of the equipment? The answer is the latter: the performance of the equipment! Specifically, in the market there is only suction without pressure of the suction molding machine, there is only pressure without suction press, and then there is suction and pressure of the suction and pressure molding machine, Nanjing Bia company has introduced a fourth set of suction, pressure, blowing one of the acrylic suction and pressure blow molding machine. Due to the different structure of various types of equipment, the function is of course greatly different, the manufacturing cost of equipment is of course different. For example: Beijing ×××× company launched the × × × series, it is of course also the use of thermoforming principle, but the series of equipment is only a vacuum system, so there is only a suction molding function, in the acrylic products business, the use of such equipment, the same made in different forms, colorful products, only the product convexity and concavity can not be obvious, so it is precisely because of this type of equipment structure of the surface of a single, low-cost, incomplete functions and so on. For this reason, the market price is only about 20,000 yuan (with a working surface of 1.5m × 2.6m, for example). Guangdong market is commonly used in another device is only pressure does not suck the press, because the function of this equipment is only pressure, simple structure, low cost, so in the acrylic products industry in the early stage of development, comprehensive around are widely used, in fact, it is only limited to woodworking industry commonly used simple presses only. But because of its function and only suction not pressure suction molding machine obvious difference, so this kind of equipment can only make angular products, where the corners are not obvious, only with the suction molding machine to complete the product, this kind of equipment can only look forward to! Because of the limitations of the above two types of equipment, acrylic equipment manufacturers have introduced a set of suction, pressure in one of the modern meaning of acrylic suction molding machine! Of course, on the one hand, depending on the domestic market for acrylic products is maturing, on the other hand, depending on the merchants of acrylic products, standards and requirements are becoming more and more stringent, there is today's acrylic suction molding market maturity, maturity, inevitably bring the competition in the market, the market competition prompted by technological advances, but at the same time will produce a mixed bag of market phenomena. Third, the main technical parameters of acrylic suction molding A complete acrylic suction molding machine, must contain several major technical parameters, heating power, heating temperature, suction pressure depth, height of the lifting platform, suction pressure table specifications, suction negative pressure, etc., in fact, they are the heating softening system, pressure molding system, suction molding system, such as the quantitative indexes of the three major systems technology. 1, heating and softening system: acrylic heating and softening methods used in the country, mainly electric power heating, in the application of a few businesses use gas heating, but because of its safety, convenience and other factors, gas power heating method used are very few. Since electric power heating, it involves the voltage standard, power, heating temperature and so on. At present, the acrylic equipment manufacturers to provide equipment, there are 220V and 380V, mainly depending on the customer's power supply, but because the thermal efficiency of 380V voltage than 220V to be higher, faster heating speed, so the general recommended use of 380V industrial power packages. (1) the concept of heating power and electricity consumption difference to Nanjing BY introduced BY-X2 large-scale equipment, for example, the maximum heating power of 27KW, the actual Nanjing BY using sub-bin heating method, that is, only need a small plate, can be used to open only half of a bin that is, one-half of the approach to energy-saving one-half of the total energy consumption, that is, 27KW/2 = 13.5KW, while the use of the principle of thermostat refrigerator is not the heating system Has been in the state of maximum heating power, so one hour consumption of 27 degrees of electricity or 13.5 degrees of electricity calculation method is wrong. (2) The concept of adjustable temperature Due to the thermal deformation temperature of acrylic panels between 140 ℃ - 180 ℃, the heat into the temperature is generally around 100 ℃, so the general situation of the temperature is set at about 200 ℃ can be, and PC, ABS, PVC and other materials such as thermal deformation temperature and acrylic are very different, so the adjustable temperature adapted to various types of panels used. At the same time, a key issue is the softening speed of acrylic sheet heating by the temperature inside the softening box is extremely obvious, such as 3mm acrylic sheet at 200 ℃, about 7 minutes to reach the softening requirements of the suction molding, and at 300 ℃, about as long as 4 minutes to reach the standard, it determines the speed of the work of the acrylic products, but according to the physical properties of the acrylic sheet, generally in the 200 ℃ or so heating is better, the temperature is too low, the speed is too slow; temperature is too high, the performance of the sheet is more destructive. Here, there is a joke to tell, many of the acrylic equipment manufacturers in the labeling parameters marked 0 ℃ - 400 ℃ (adjustable). I do not understand the equipment to be adjusted to zero degrees, how to operate? I understand the domestic acrylic equipment manufacturers have not been added to the refrigeration system, then in Guangzhou 35 ℃ room temperature, if adjustable to 0 ℃, I believe that this equipment is better than the refrigerator to sell, because the refrigerator's biggest drawback is that it can not be used as a microwave oven! (3) the heating method At present, the Nanjing Bia's Yakeli brand has been under the baking heating method, that is, far-infrared heating tube under the top is an iron plate covered with asbestos cloth, acrylic panels are placed on the asbestos cloth heating. Nanjing Bia company's reasons are two, the first heat conduction upward heat rate effect is high, as baked groundnut in the end, on top or on the big below fast? Self-evident; second, the asbestos cloth can make the heat conduction more uniform, while preventing the friction damage of the iron plate on the acrylic plate. Of course, there are also acrylic panels placed under the heat pipe, but the two are different, can be heated to a predetermined temperature of the acrylic panels are right. 2, pressure molding system The pressure molding system is the key to acrylic sheet molding, because it determines the basic value of each acrylic suction molding machine. In this system, it determines the suction press pressure, size, suction pressure depth, etc., the actual purchase of acrylic suction molding machine, it is the most critical one of the technical indicators. Why? Because the stroke of the hydraulic cylinder of the pressure molding system determines the lifting height of the lifting table, the lifting height determines the suction depth, the suction depth determines the use of the acrylic suction molding machine you buy! Use is the purpose and significance of the purchase. At present, the mainstream products produced by Nanjing BY-X2 type machine BY-X2 stroke is 65cm, is the main domestic equipment manufacturers in the hydraulic cylinder stroke is the longest, the basic method of measurement is: the stroke = the telescopic length of the hydraulic cylinder; lifting height = the effective distance between the working platform and the lifting platform. In fact, the stroke in the hydraulic system has 45cm, 50cm, 65cm, 80cm, 100cm, 120cm and other specifications used in acrylic suction pressure molding. However, in the marketing process of acrylic equipment manufacturers, the vast majority of the equipment with a stroke of 45cm, especially heating, suction pressure molding all-in-one machine, more than 90% is this type. However, with the maturity of the acrylic products market and the diversification of acrylic products, the limitations of low stroke equipment is becoming increasingly obvious, especially in the manufacture of handicrafts, display products production, can not meet the basic requirements of the business. For example, in the recent production process of Nanjing Bia company, more and more customers customize the stroke of 80cm, 100cm, 120cm equipment, will not repeat here. But there is a second joke that has to be told. Anyone who has an understanding of China's industrial development, probably know that hydraulic technology is one of China's most mature industrial technology, so the general hydraulic machinery in the country does not need to be imported, if some of the acrylic equipment manufacturers always reiterate the use of hydraulic systems are imported, is it a little funny? At least I know that I have the same user in Guangzhou, the hydraulic parts market even an imported hydraulic system with screws are not found. 3, vacuum suction system Vacuum suction system, also known as the suction molding system, it is a vacuum by the vacuum to generate negative pressure vacuum suction molding function system. It determines the special features of acrylic suction molding machine. In fact, the vacuum suction system is composed of two main parts of the vacuum pump and vacuum tank, and the vacuum pump in the unit of time produced by the negative pressure is a certain amount, only through the increase of the vacuum tank solution. Here again, the acrylic suction molding machine function and sales price of the problem. Nanjing BY-X2, for example, is now in addition to the use of high-power vacuum pump, but also attached to a diameter of nearly 1 meter, more than 2 meters long vacuum tank, which is unique in the domestic acrylic suction molding equipment, the size of the negative vacuum pressure is commonly used megapascals (Mpa) that the size of the negative vacuum pressure in the acrylic suction molding machine is generally zero to minus 0.1 megapascals (0 ~ -0.1Mpa), the size of the negative pressure in acrylic suction molding machine. If in the same piece of acrylic sheet suction process, if the maximum negative pressure of 0.1Mpa since the beginning of the vacuum, if the diameter of 1m, length of 2m vacuum tank 10 seconds, the negative pressure of negative 0.08Mpa, and if the diameter of 1m, the length of 1m vacuum tank 10 seconds, the negative pressure of negative 0.02Mpa. These two cases on the molding effect of acrylic products Of course, it is not the same, especially when the processing of acrylic panels with a large area, the effect of the contrast is more pronounced. However, it is undeniable that, in the domestic acrylic suction press molding machine manufacturers between different businesses to create a different vacuum system, some vacuum tanks as small as a large basketball, some simply do not have, only the vacuum pump suction pipe connected to the suction pressure platform, simply can not achieve the purpose of suction vacuum. Whether experienced buyers, without much asking, as long as you take a look at the size of the vacuum tank, you know the function of the vacuum system and suction effect. In particular, there are acrylic products in South China, by the foreign market, some purely foreign orders, so customers in South China are more stringent requirements for the vacuum system of acrylic equipment, such as Nanjing Bia company's Yakeli suction-pressure blow molding machine, after repeated requests from users in Guangdong, to achieve today's design and manufacturing results.
