laminating machine——SMFM-390C/520C/650C

How to choose a suitable laminating machine?

1. Select equipment

If we carefully observe the everyday purchases, we will find that the equipment selected by each manufacturer's vacuum laminating machine is different. For example, manufacturers may choose sheet metal and iron, two materials with entirely different functions. To manufacture vacuum laminating, the quality will naturally vary greatly, and customers should pay attention to this.

2. Pick the type

Many people may not know that there are many detailed classifications of vacuum laminating. And we can divide the vacuum laminating machine into semi-automatic vacuum laminating machines, automatic vacuum laminating machines, upper and lower heating vacuum laminating machines, upper heating vacuum laminating machines, and positive and negative pressure machines according to the different product structures. There are five major categories, each with very other products and equipment. Before purchasing, customers must choose the appropriate category of products according to their needs.

3. Look after sales

After all, vacuum laminating is a kind of mechanical product. Various failures will inevitably occur in the daily use of products. If the manufacturer can provide perfect after-sales service, customers will undoubtedly have a lot easier later use of products.

What is the difference between the membrane?

According to raw materials' printing and processing method, self-adhesive labels are divided into single-sheet paper lamination and roll material lamination. A sheet of paper is laminated on the laminating machine. The raw material of the roll is compounded in the compounding process of the labeling machine or on a particular compounding machine.

Specifically, it can be divided into the following categories:

1. Roll paper lamination

According to the different facilities, roll paper lamination can be divided into:

Lamination of composite liner film - carried out on the labeling machine, the unique composite film with liner is used, and the film is laminated under the action of the composite equipment. This is also a traditional lamination method. In recent years, it has been replaced by the linerless hybrid film processing technology.

Lamination of the linerless composite film - carried out on the labeling machine; the basic principle of Lamination is the same

The basis of the composite processing technology of the backed paper composite film is the opposite. The linerless film can replace the liner after rewinding by its material's surface gloss (surface tension). After the adhesive is bonded to the surface, it can be detached without leaving any glue traces. The material used for the linerless film is BOPP film with low surface tension. Linerless film lamination is low-cost and is the most commonly used lamination raw material.

2. Single-sheet lamination

According to the essential functions of the laminating machine and the characteristics of the lamination film, there are two lamination methods for single-fed paper self-adhesive labels:

Ready-to-coat Lamination—on a laminating machine. The whole Process of compounding is as follows: first, the adhesive is applied on the surface of the reel BOPP film, and the organic solvent in the bond is evaporated by drying treatment equipment, and then the single sheet of paper is compounded with the reel film in the compounding process. Under the hot barrel extrusion, the two become one, and the lamination process is completed.

Pre-coating film compounding—the surface of the compounding film is pre-coated with adhesive, and there are two types of films: hot-sol type and pressure-sensitive type. The laminating machine is equipped with a heated imprinting cylinder. When laminating, the pre-coated film touches a single sheet of paper. Under the effect of the hot-pressing cylinder, the adhesive is melted so that the film and the report are bonded together. If the pressure-sensitive composite film is used, the heating switch power supply can be turned off, and the composite film can only be composited by pressure.

3. UV lamination processing technology

The new overseas processing technology is mainly used in the equipment-type rotary labeling machine with UV drying device. The working principle of the processing technology is: the surface of the laminating raw material is first printed with the UV adhesive by the general printing module, and the adhesive is dried and solidified by the UV drying device and then becomes a pressure-sensitive adhesive. Then, the available BOPP film (generally, the composite surface has been corona treated) is composited with the raw material of the roll in the lamination process, and the lamination process is carried out. UV lamination is low cost, the tension change of the composite film is small, no particular movie is required, and it is suitable for rapid production. UV coating is a promising processing technology used in Western capitalist countries at this stage.

4. Dry Lamination

It is carried out on a laminating machine or a gravure printing machine and is mainly suitable for the Lamination of film raw materials. Roll raw material dry lamination is ideal for many label products, and the Lamination is cost-effective and low-cost. After the roll label is covered with film, it is generally necessary to carry out secondary production processing, such as film cutting and waste discharge on the processing equipment, such as some battery and wine labels.

What is the advantage of the fully auto laminating machine?

The inevitable trend of automatic film laminating machines replacing manual filming In today's rapidly rising labor value, it is an inevitable development trend to replace manual production with automated equipment. Cut unnecessary costs and improve ROI.

An automatic laminating machine is a typical representative of mechanical equipment. We can find that film is something we see every day, such as mobile phones that we can't live without for a moment, as well as industries such as hardware, plastics, electronics, toys, food, daily chemicals, medicine, etc. It can be said that it can be seen everywhere, and with the development of technology, It is destined to replace manual operation with automatic filming.

The automatic laminating machine is a special equipment to replace manual Lamination, especially for mobile phones, hardware, plastics, electronics, toys, food, daily chemicals, medicine and other industries.

6. The machine is simple and valuable, and the staff is sensitive to the operation and debugging.

What are the machine parameters of the machine?

It's a digital Auto-cut laminating machine(with overlap, oil heating and pulling off). We have three types of this machine: SMFM-390C, SMFM-520C and SMFM-650C. The different number means different widths of the machine, and the other parameters are all the same. As you know, different width means the max paper size differs from each other. Their max paper size is 370mm、485mm, 、630mm. Their operating speed is all 0—13m/min, and the laminating temperature is 50~120℃. Besides, the total power is all 3kw, and the pressure is 0~5MPa. Finally their dimensions(L×W×H ) are respectively 1.6x0.68x1.2m, 1.6x0.8x1.2m and 1.6x0.92x1.2m.

What is the influence that laminating machine does on the printed matter?

The laminating machine is to coat the plastic film with adhesive. After being pressurized by the rubber drum and the heating drum, it is combined with the printed matter based on paper to form a paper-plastic integrated product. The coated print has a thin and transparent plastic film on the surface, making the surface smoother and brighter. It not only improves the gloss and fastness of the printed matter and prolongs the service life of the printed matter but also protects against water, dirt, abrasion, folding and chemical corrosion.

How to keep the efficiency of the laminating machine?

1. The laminating must also pay attention to the direction of the line of the paper. Especially thick paper can reduce the phenomenon that the report is pulled by the roller and curled.

2. Be sure to wait for the traces to dry before covering the film. Otherwise, foam or long hair will result.

3. The maintenance of the rollers of the automatic coating machine is also essential, frequent expansion, uniform pressure, and keeping the rollers clean. Before working, let the rubber roller preheat for 10-20 minutes to improve the film's quality.

4. Temperature control is significant, preferably 40 to 60 °C (low-temperature cold surface). If the temperature is too high, the paper and film will be deformed, and the product will be bent, and if the temperature is too low, the viscosity will not be enough. The temperature of coated paper should be lower than that of uncoated paper.

5. The product to be constructed must be kept straight, and the uneven paper with the phenomenon of "frilly" and "tighten the edge" should be handled. The ruffled piece can be baked, and the tie-edge" paper can be hung to dry.

What impact does the laminating machine bring to the digital processing industry?

Small laminating can be divided into two categories: instant coating laminating and pre-coated laminating. The pre-coated thermal laminating machine is also called a thermal laminating machine. It is widely used in various modern wedding dresses, art photography, computer inkjet painting, calligraphy and painting, posters, advertising pictures, renderings, documents, etc., less investment, noticeable effect, the consumables used are non-polluting, are green products, and have excellent market potential.

Laminating the surface of digital prints, especially after printing a large area of solid, will help protect the images in post-press processing, significantly when cutting or packaging, and enable printing. The product is more beautiful and durable. However, single-sided Lamination of double-sided prints is not necessarily beneficial because the uncoated side may easily peel off the printing color due to friction in the subsequent processing. To pursue distinctive effects, many printed products are covered with various bright, matt, and matte films on the surface. However, it is more appropriate to use thermal Lamination for digitally printed prints, which is easy to use and inexpensive.

What is the prepress design of the laminating machine?

At the beginning of the design of the printed matter, the Lamination should be considered; that is to say, when designing the printed matter, the designer should take into account which processes and what kind of Process, what paper and ink to use.

The covers of books, magazines and other publications are often filmed due to poor filming conditions when using a pre-coated film machine, resulting in unqualified surfaces. In the cover design, if our designers design the color to be light or even colorless at the rolling line so that the adhesion here can eliminate the interference of ink, there is no problem with filming. Likewise, pre-coated films are not suitable for metallic inks and are prone to filming. Therefore, for the lamination problem, the designer of the printed matter should know how many processing steps the printed matter needs to go through, what impact each processing procedure has on the Lamination, and how to avoid such an impact to improve the yield. This requires designers to master the effects of printing, bronzing, local UV, rolling line, bump and other processes on Lamination during design.

What are the cleaning methods for the glue roll?

Lamination is commonly known as over-gluing. Whether it is cold Lamination or hot Lamination, rubber rollers are needed to assist. If the rubber rollers of the laminating machine are not cleaned and maintained well, dust or hair is stuck, and it is easy to appear sand, stripes, and worms. The film's bulging and emptiness in the shape of moiré or moiré is also called "bubbling." Therefore, in addition to maintaining a specific temperature and humidity in the working environment, the impact of dust on the machine should also be reduced.

Therefore, after using the laminating machine, pay attention to cleaning. The rubber roller should be wiped clean. You can use a sticky note, a clean cloth towel dipped in distilled water or alcohol to brush, it does not need to be too large, and then it can be dried in the air. Be careful not to use washing powder, gasoline, etc. Detergents such as cleaners, because the rubber rollers of the cold laminating machine are mostly made of polyurethane. If it is idle for a long time, it is recommended to disassemble the rubber roller and wrap it to prevent extrusion deformation.

Why does the laminating machine occur the phenomenon of stray?

1. The inside of the oil cup is too dirty, the filter screen is blocked, or the oil level of the oil cup is low.

2. The power steering system contains air.

3. There are foreign objects in the steering system, which causes the flow control valve of the steering pump to be stuck.

4. The tire pressure is insufficient, the steering column of the pump interferes, the connection is loose, the pump's belt is loose, slips, or the installation position of the pump is open.

5. The bolts of each connection part of the oil pipe are loose, resulting in steering fluid leakage.

6. The piston cylinder of the steering gear is too worn, the oil seal is not well sealed, and the control valve is bonded or damaged.
