After the small laminating machine is adjusted, the pre-processed printed matter is sent to the paper feeding mechanism for laminating, and samples are taken for inspection. Use a small amount of printed matter to inspect before laminating, so as not to cause a lot of waste. After passing the inspection, mass production can be carried out. The method of using the film inspection is as follows:
1. Tear off the corner of the proof sheet completed by the lamination in the width direction, press and hold the paper, and tear it all in the width direction. After tearing off all the tears, if the graphic imprint on the surface of the printed matter follows the glue layer and the fiber of the paper Transferred to the film, it means that the printed matter and the film adhere well, and it is a qualified product.
2. Put the film-coated sample into the drying tunnel and bake at 60-65 degrees Celsius for about 30 minutes. If there is no blistering, no delamination and no wrinkles will occur, and it is a qualified product. After baking, the tear film should not be separated from the paper intact.
3. Immerse the sample in cold water for 1 hour and take it out. If the plastic film is not separated from the printed product, it is a qualified product.
4. Put the sample on the creasing machine and apply pressure. If the pressed uneven part does not delaminate, it is a qualified product.
In summary, after one or more inspection methods meet the requirements of the sample of the small laminator, it can be put into mass production. If it does not meet the requirements, the sample fails, the pressure adjustment process is retested, until the inspection is qualified.

The laminating machine is a kind of product in which a plastic film is coated with an adhesive and printed with paper as a substrate after being pressed by a rubber roller and a heating roller to form a paper-plastic product. The classification can be divided into coating laminating machine and pre-coating laminating machine. The printed product after the coating has a thin and transparent plastic film on the surface. Fastness has prolonged the service life of printed matter, so how can the amount of film be reduced when laminating? Let Xiaobian introduce it to you.
The amount of film used by the film laminating machine is mainly related to the operation level, so it is generally recommended to:
1. The product to be constructed must be straight. Handle uneven paper with "ruffled edge" and "tight edge" phenomena. Paper with "lotus edge" can be baked, and paper with "tight edge" can be hung to dry.
2. Be sure to wait for the blot to dry before coating, otherwise it will cause blistering or hair pulling.
3. Spray as little powder as possible during printing, otherwise it will cause emptying and bubbling at the powder pile. Before spraying the film, the powder should be disposed of. If the number of prints is large, the powder can be hung to remove the powder. If the number of prints is small, the powder can be wiped manually.
4. Check the photo paper is clean before laminating, laminating the film in a clean environment.
5. When laminating, attention should also be paid to the direction of the paper strands, especially thick paper, to reduce the curling of the paper due to rolling and stretching.
The above is the relevant introduction to the recommendations for reducing the amount of film used when laminating the film. I hope it will help you
What faults will occur in the normal operation of the vacuum laminator, how to eliminate it?
In recent years, the pollution of the laminating machine has been effectively controlled, which deserves a good extensive evaluation by the industry. What kind of environment is the vacuum laminating machine completed? It is a film that is vacuumed between the film and the painting and is stable under certain conditions.
However, the complexity of its operation makes the cost high and the quality has certain limitations. Then what kind of failures will occur in the usual operation, how to eliminate it?
First, the machine does not start because the voltage is not enough, the input wires are different, and the power cord is reversed;
Second, if the installation is incorrect, it will cause inaccurate temperature measurement;
Third, the failure of the gas circuit will cause damage to the vacuum gauge;
Fourth, the total power supply will often have leakage, tripping and other phenomena, which have certain hidden dangers;
Fifth, if the degree of vacuum does not meet the requirements, not only air leakage will also cause problems in the quality of the membrane;
Sixth, the production process must ensure that the surface is smooth and polished in place, otherwise there will be film quality problems;
Seventh, we must always pay attention to whether the hand valve is opened, so that it will not pull down when the film is covered;
Eighth, the heating temperature should not be too high, it will cause the phenomenon of breaking.
With the development of woodworking machinery enterprises, vacuum laminating machines are more and more applied to this industry. Next, I will teach you how to operate vacuum laminating machines correctly!
1. Check whether the pressing device and the rotating parts are in good condition before going to work.
2. Clean up the dust and scum in the workbench.
3. Prepare necessary product pads (6-8 mm smaller than the workpiece) and other necessary materials.
4. The vacuum laminating machine checks and adjusts the temperature and schedule setting values according to the thickness of the film material.
5. When processing multiple pieces together, the appropriate distance should be placed according to the thickness of the processed board (generally 3-4 times the thickness of the board).
6. Before starting the heating hood, check whether the clamping frame is locked, whether there are objects and personnel hands on and around the guide rail.
7. During the operation of the vacuum laminator machine, it is strictly forbidden to stand around the machine, let alone put the hand on the guide rail and equipment, to prevent the machine from automatically returning to the heating cover to hurt people.
8. It is strictly forbidden to place products and other objects on the heating hood.
9. Turn off the power immediately when the machine is found to be abnormal, and notify the supervisor
10. Do not disassemble safety and other protective items at will.
11. The operator must not leave the machine during work.
12. Turn off the power when the work is completed. The above is the operation procedure of vacuum laminator. Everyone must operate according to the correct method and regulations, otherwise there will be danger.
The laminating machine is a machine that combines paper documents with plastics; the key to the longevity of the machine lies in the usual correct operation and maintenance. The accuracy of the automatic laminator is very high, especially the surface accuracy and shopping degree of each roller. Once the slightest streaks, cracks, scratches, obscuration, or a slight roundabout deformation. All will affect the processing quality of the product, even not working properly. Therefore, it is very important to protect the automatic laminator carefully and carefully. Here are some knowledge. If you want to use the automatic laminating machine for a long time, you should always check the oil pipes, valves and cylinder plugs of the hydraulic system for oil leakage, and often check whether there is rubber or grease on the rubber roller. Scrub the glue and dust on the roller in time. The grounding of the machine and the insulation of electrical appliances should be ensured. The transmission parts and sliding surfaces of the machine should be regularly lubricated to ensure that the machine is in a good lubrication state. A comprehensive inspection of the machine should be carried out every year to find problems and solve problems in time In order to avoid more serious damage to the machine.
Let's take a look at what matters need to pay attention to when buying a laminating machine?
First, consider the range of applications you want. Depending on the desired application, the printing company may need a fully functional laminator (much more expensive) or a laminator with limited functionality (low cost and high benefit).
Second, the overall size. The maximum size required by your application will determine the width of the machine. The width of the laminating machine must be wide enough to accommodate the maximum printing width in order to maximize the output and production of the printer.
Third, whether heating is required. Your application will also determine whether your laminator is cold, a heat-assisted type heated only by the upper roll, or a whole-heated type (for encapsulation). Encapsulation involves applying heat-activated heat-sensitive films on both sides of the print. The finished product is cut, leaving a transparent edge around the print, so it is called encapsulation. Some applications require integral heating or the use of upper roller heating to better perform lamination. Therefore, it is important to consider whether the main application requires integral heating (encapsulation) or single-sided heating (pressure-sensitive adhesive). If the main job function is encapsulation, the cold roll laminator cannot be used.
Fourth, do you need the ability to install, and the maximum size of the substrate that the machine can install. If you just install it on the foam core, you won't need a wide installation gap. However, if you want to install on a thicker substrate, you will want a larger installation gap.
Fifth, do you need a roll-to-roll function. In some applications (such as car body stickers), a roll-to-roll function is required to ensure that the product can be delivered in the form of a coil.
Everyone is yearning for good and cheap goods. For the same reason, the reasonable price of vacuum laminating machine is also the first choice for every company that needs to use this type of equipment when purchasing goods. So, what are the factors that can affect the purchase price of the vacuum laminator? Now let's understand together.
1. Product type
In fact, the type of vacuum laminator is one of the important factors that determine its price. Due to the different characteristics of the products that require service, the production type of the laminator will also be different. If you exclude other factors that will affect the price of equipment, usually, the larger the volume of products that the equipment can serve and the higher the efficiency that needs to be provided, the greater the purchase price that will be spent.
2. Transportation costs
In fact, due to the issue involving freight, freight is also an important part of the purchase price. The distance between the manufacturer and the purchasing company usually directly affects the price of freight. Of course, the amount of transportation costs will also be affected by various external factors, including transportation methods, transportation routes, the size of equipment, and even the relationship between the manufacturing company and the transportation company. In the actual procurement activities, due to differences between companies, the transportation costs of vacuum laminators will also be somewhat different, resulting in different purchase prices for the same type of equipment.
3. Brand strength
Usually, the brand strength will also affect the purchase price of the vacuum laminator. The cost of purchasing the equipment of the first-class vacuum laminating machine production enterprises is usually greater than that of ordinary enterprises. This is mainly because companies with strong brand strength need to be equipped with a strong team and professional service personnel, and these costs will inevitably affect the purchase price of the company.
Of course, in addition to the above-mentioned product types, transportation costs, and brand strength, which will have a certain impact on the purchase price of the vacuum laminator, the after-sales problems of the machine, including the replacement and maintenance of various parts and components, will affect the purchase price. Affected. Of course, it is also recommended that purchasing companies choose manufacturers with guaranteed after-sales service for vacuum laminators.
