Reasons for the failure to seal panel furniture

Due to the fact that the engine of the sealing machine does not match well with the track, the track is not stable during operation and is wavy, resulting in gravitational attraction between the seal and the end of the plate, causing the edge of the seal to be uneven. Unfavorable equipment trim edge(equipment itself with trim edge knife); Coating roll and belt roll coordination is not good, lack of glue or uneven coating is very common; The trim tool and the angle tool are often poorly adjusted. Not only does it require manual additional trimming, but it is difficult to ensure the quality of the trimming edge. In summary, the quality of equipment is the most common and sustainable due to the poor level of commissioning, maintenance and maintenance.
II. Plate

As a substrate, the thickness deviation is generally not up to the standard, and it is mostly positive tolerance, and often exceeds the tolerance allowed range(tolerance range 0.1 ~ 0.2 mm); The smoothness is not up to standard. This makes it difficult to grasp the distance from the compaction wheel to the surface of the track(thickness of the substrate). Too small a distance can easily cause over-compression, increased stress, and open rubber; Too large and not tight spacing plate, the sealing edge bar can not guarantee strong binding with the plate end.
III. Processing precision

In the process of processing, the machining error mainly comes from the material opening and cutting. Due to the equipment system error and the worker's processing error, the end surface of the workpiece can not reach the level and can not be maintained perpendicular to the adjacent surface. Therefore, when the sealing edge can not be fully in contact with the end surface of the plate, gaps or exposed after the sealing edge. The substrate affects aesthetics. What's more, the base material has collapsed during the processing process, and relying on the edge is difficult to cover
Closed-side materials

Most of the sealing materials are PVC sealing strips, which are greatly affected by the environment. Harden in winter, the affinity for glue decreases, coupled with a longer storage time and aging surface, the adhesive strength of glue is even lower. For the sealing strips with a small paper thickness, due to their large toughness and too small thickness(such as 0.3 mm thick), resulting in defects such as uneven cutting of the sealing strips, insufficient adhesive strength, and poor trim effects, the rework rate is high. The sealing bar waste is also very serious. The adhesive sealing edge is a special sealing edge hot melt adhesive. Due to the low temperature in winter, in order to ensure the glue and strength, the temperature of the glue is slightly higher. If it is too high, the adhesive is too thin, and the adhesive layer becomes thin, it has cooled down when it is painted on the end surface of the plate, and the temperature of the sealing edge is also low, resulting in a significant decrease in the strength of the sealing edge. If the temperature is reduced, the glue is a bit thick, but the temperature of the seal is lower, and the glue and strength are not enough. The lower the temperature, the glue won't melt very well. In production, this contradiction is very prominent and difficult to solve. In addition, the adhesive quality of the adhesive itself and the adaptability and affinity between the substrate and the seal bar affect the quality of the seal.

Yosemite glue has a strong technical team. Over the years, according to the actual situation of the market, it has continuously studied and innovated to provide dealers and furniture companies across the country and at home and abroad with better quality and more stable thermal melt glue. Helped solve the difficult problems in the production process. As the leading company of China hot melt glue, do the best value for money products, to do things with conscience, is the winning person has always insisted on the attitude, we provide you not only products, but also a strong technical force support.
