Understand the causes of hot melt adhesive wire drawing, and solve the problem according to different reasons.
1. Hot melt glue machine temperature is low. The temperature of the hot melt glue machine is too low, which will make the glue thin and cause wire drawing. Therefore, in this case, you can first consult the glue construction temperature of the hot melt glue manufacturer and appropriately increase the temperature setting.
2. Hot melt adhesive cohesion. When the cohesion of the hot melt adhesive is large, the adhesive has a greater probability of resisting deformation during the construction process and is not easy to break, resulting in obvious wire drawing. The smaller the cohesion, the easier it is to break during construction and not easy to produce; In meeting product adhesion
Hot melt glue dispenser drawing problems are usually caused by glue pressure or temperature instability, solutions include:
First, check whether the glue pressure is appropriate and adjust the glue pressure properly until the drawing problem is improved;
Secondly, ensure that the temperature of the hot melt adhesive is stable to avoid too high or too low temperature; In addition, it is also necessary to check whether the glue needle is blocked or worn, and clean or replace the damaged needle in time. Through the comprehensive adjustment of the above methods, the problem of hot melt glue dispensing machine drawing can be effectively solved.
