What are edge banding materials?

      The edge banding machine is a kind of woodworking machinery, and it belong to one of panel processing equipments.  There are various types of edge banding materials: PVC, Wood veneer, Polypropylene, Melamine, ABS, Solid wood.

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.

    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.

What are the disadvantages of PVC edge banding material itself?

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.

  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.
