What is Edge Banding？

       The edge banding machine is a kind of woodworking machineries. It belongs to the solid wood machinery category. The traditional manual operation process is completed by highly automated machinery. Including conveying in straight-face premilling, gluing, end cutting(front and rear alignment) , upper and lower rough trimming ,upper and lower fine trimming ,upper and lower scraping, and polishing and many other processes can be added as requirement.

Types of Edge Banding materials

Edge banding can be made from various types of materials. I will list them as the following:

1.PVC

2.Wood Veneer

3.Polypropylene

4.Melamine

5.ABS

6.Solid Wood

PVC

    The main raw material is polyvinyl chloride, and various additives, such as plasticizers, stabilizers, lubricants, dyes, etc., are added, and thermoplastic coils are obtained by mixing and pressing. It has the realism and three-dimensional effect of wood, a certain degree of finish and decoration, as well as a certain degree of heat resistance, chemical resistance, and corrosion resistance.

What are frequently Questions about PVC Edge Banding?

     1-  Trimming has whitening phenomenon

In the process of using edge banding strips, sometimes it is found that there will be whitening when trimming, which is a normal phenomenon, which is generally caused by manual edge banding machines or semi-automatic edge banding machines, because they are not as automatic as automatic edge banding machines. The device does have a polishing function. During the edge banding process, if the edge banding strip with a thickness of less than 0.6mm is softened, stretched, deformed, or cannot stand high temperature, it is because the edge banding speed is too slow and the residence time of the hot melt adhesive is too long after melting. Speed up the edge banding speed, high-speed conveyor belt speed, and adjust the amount of glue to improve. The reference speed is above 8M/min. If it is an edge banding machine with double-sided glue, this phenomenon generally occurs less frequently. 

     2- Can not be sealed

      In the process of using the edge banding, we often see such a situation that the edge banding cannot be sealed. At this time, check whether the temperature is normal, whether the edge sealing speed is too slow, and whether the room temperature of the use environment is lower than 8 degrees. If the glue line is too heavy, or there is glue overflowing and drawing, please adjust the speed of the edge banding machine. If the temperature of the hot melt adhesive does not improve after adjustment, please replace it with a suitable model.

Disadvantages of PVC edge banding material itself

    1- Insufficient stability

PVC edge banding with a thickness of more than 2mm has a certain stress. It must be heated to soften or increase the temperature of the adhesive during use, otherwise it will fall off due to the poor adhesion of the stress. According to industry experts, PVC edge strips are prone to problems of insufficient stability.

The situation that leads to the insufficient stability of PVC edge banding. First, the heat stabilizer of the PVC edge banding of furniture is unqualified or improperly selected or the amount of heat stabilizer is insufficient. Second, the setting of the processing temperature is unreasonable, mainly because the temperature is too high. Third, the screw speed of the extruder is too fast. Fourth, the combination or dosage of internal and external lubrication in the formula system is unreasonable.

   2- The problem of light aging resistance

In general, reasonable mixing and processing conditions will greatly reduce the impact of volatile components in the raw materials. In order to quickly evaluate and predict the light aging resistance of PVC materials, it is necessary to establish an artificial accelerated UV aging simulation experimental system. Because the light aging period of PVC edge strips under natural climate exposure conditions is long, it is beneficial to obtain experimental results in a short time, and provide theoretical basis and basic data for evaluating and predicting the light aging resistance of PVC edge strips surface.

Whether exposed to natural climates or accelerated by artificial UV light, the temperature is always accompanied by the entire cycle of the test. Under light, the surface temperature of PVC materials of different colors can reach as high as 70 ℃. The parameter values of the PVC edge banding strips changed after 168 hours under different heating conditions, and the changes were larger at 60°C and 80°C.

Wood Veneer

      Its advantages are light weight, convenient construction, natural winter warm color, strong decoration, good insulation, small deformation, green environmental protection, cool summer, so that the beauty of the indoor space can produce people's enjoyment, and the indoor space can be beautiful. These vehicles The criss-crossing factors are easy to corrode, susceptible to burning insect spots, different performance and mechanical properties, controlled, easy to crack, warp, etc. after adjustment, but not enough, there must be a feeling of processing, which can be compared through chemical and radiation treatment. The resulting ecosystem has good moisture absorption, water resistance, transmission properties, and ideal strength.

Polypropylene

      First of all, it is safe, environmentally friendly and harmless, and tableware made of pp materials has been used in the market for many years as an example. Secondly, the dimensional stability of PP edge banding is better. Pp edge banding has good heat resistance and does not deform at 150°C. It is suitable for edge sealing of furniture with high temperature requirements such as cabinets. Good anti-corrosion effect. There are also Pp edge strips that are not whitened when bent. The most prominent performance of Pp is the resistance to bending fatigue, and its products can be bent dozens of times at room temperature without damage. Pp edge banding is easy to operate. However, Pp will be embrittled when encountering ultra-low temperature, the embrittlement temperature is -35 °C and its wear resistance is slightly poor.

Melamine

     Melamine Edging is an ideal way to finish the exposed edge of Melamine faced MDF, chipboard or other panels. Used extensively in the manufacture of kitchens and home & office furniture, it is a specialist resin-saturated paper which is lacquered to give it resilience.

      Melamine Edging is available in a wide range of colours and wood effects. Offered in pre-glued, easy to iron on, and some un-glued.The surface is flat, because the double-sided expansion coefficient is the same, the plate is not easy to deform, the color is bright, the surface is relatively wear-resistant and corrosion-resistant, and the price is economical. Various patterns can be imitated arbitrarily, with bright color, used as veneer for various wood-based panels and wood, with high hardness, wear resistance and heat resistance. Good chemical resistance, can resist the wear of general acid, alkali, grease and alcohol and other solvents. The surface is smooth and clean, easy to maintain and clean. However, the edge sealing is easy to collapse, the glue marks are more obvious, and the color is less, so it is not possible to directly seal the gongs and flowers.

ABS

     The texture of the wooden strips is soft, uniform and uneven, and the natural characteristics of the strong wooden strips are evenly attached to the coating. Everyday edge-sealed furniture has a good fit, especially the wood strips that are seamless with the gauze edge. Strong, easy to use wood, easy to use, strong skin elasticity, convenient after chewing, control of light on the surface, hairiness, easy to break, so moderately convenient to use, because wood packaging is generally used. 8%, when it is controlled between % and 12%, it needs to be between 15% and 2%, and more sidebands are added to seal the edges. 0 Edge sealing needs to be negotiated and then equilateral processing. Wooden edge strips are mainly suitable for stickers and decorations on the surface of solid wood furniture, and can only be done by hand-made pasting methods. Due to the wet and wet materials of animals, the operation rate will change due to the influence of temperature and adhesion. Therefore, choose the appropriate adhesive and adaptor according to the leakage and leakage requirements of the season.

How to Select Edge Banding?

1.Look at the hue and surface roughness of the seal.

The color of the edge banding is also very important, whether the color is close to the customized product, and the surface is bright. The main strip of the basic strip factory is the pros and cons of producing edge strips, and it is the production technology and production edge strips that are not produced and sealed at the same time. Or seldom stretched, moderate brightness, no special requirements.

2. Check whether the flatness and thickness of the surface and bottom of the edge banding strip are uniform.

If the surface and bottom of the edge banding are uneven, or the thickness is not uniform, it will cause the joint between the edge banding and the plate, the glue line is too conspicuous or the gap between the plate and the edge banding is too large to affect the overall beauty. Details determine success or failure, and often a small detail problem may bring about an embarrassing situation where the overall effect is not good.

3. Is the edge of the edge band whitish?

Whether the edge trimming is whitish, whether the surface of the bending edge banding is seriously whitish, and whether the edge trimming background color of the edge banding is close to the surface color of the board in question. PVC edge banding is mainly made of PVC and calcium carbonate plus additives. If the calcium carbonate content is too high, there will be whitening of the edge and bending, which proves that the quality of this type of product is not good.

4. Look at elasticity and lightness.

Whether the strength is okay and whether there is elasticity, high strength means good wear resistance, and the corresponding quality is also better. Too high strength also means increased processing difficulty. Low elasticity means low wear resistance and low anti-aging ability. In addition, according to the needs of actual production, it is generally necessary to manually trim the edges, so soft points can be appropriately made, and automatic edge banding machines can be appropriately made hard points.

5. Back glue situation.

Whether the adhesive is evenly applied, and whether it is easy to fall off during use.

6. Smell.

Smell whether the PVC edge banding has a smell. Products produced with good quality raw materials generally have little taste. If the smell is too large, it means that the quality of the raw materials used in production is relatively poor.

Precautions

The main advantages of the curved line edge banding machine are that the bonding is firm, fast, light and efficient. elements such as the working environment and operating methods. When choosing an edgeband, attention should be paid to factors such as width, thickness, material, toughness, and surface treatment. Hot melt adhesive should pay attention to the difference between high, medium and low temperature adhesives, match the type of edge banding, and scientifically set the heating control temperature, as well as the flowability and solidification delay of the sol. The selection of the base material also has the requirements of quality, temperature, parallelism and perpendicularity of the cut surface. The indoor temperature and dust concentration of the working environment also need to be considered. The operation speed, pressure, balance, Continuity, etc. will affect the edge sealing effect. Fourth, the maintenance method of the curved line edge banding machine There will also be some problems and failures in the use of the curved line edge banding machine.

The common failures are:

1. Electrical failure. Including the main engine stall, the heating is not fast, the program is disordered, etc., if not eliminated in time, the motor and heating tube will be burned, and even the entire mechanical system will be damaged. During maintenance, mainly check the electrical control box, motor, heating tube, delay device, etc. This kind of maintenance is generally repaired by professionals or by the manufacturer.

2. Gas circuit failure. Including air valve failure, air leakage, low air pressure, cutting knife, feeding not working, etc., mainly check the integrity of various pneumatic components, replacement parts can be carried out under the guidance of the manufacturer's technicians.

3. Mechanical failure. Mainly include transmission failure, uneven gluing, feeding failure and cutter failure, etc., mainly check the integrity and firm parts of each mechanical component, and whether the transmission part is offset.

4. Bonding failure. Such as non-stick, deviation, entrainment, etc., this is a comprehensive fault, related to the glue shaft, edge band, sol, substrate and operation. This kind of failure may occur alternately or singly, and the specific maintenance depends on the situation.
