FAQ coater and solutions

Coating machine used in the field in the past, there will be some problems, if not solved these problems, though not affect the use of coating machines, but will have the product packaging, sealing impact, today we understand the issues and solution.
First, in the coating process, there is not a continuous glue dot phenomenon, manufacturers say this time to view the coater nozzle and the distance between the material, if the distance between the nozzle and the material is too large or appear glue was guttate If the distance normal to see the volume of the plastic watering is adequate; then view the head moving speed, the glue and the moving speed is directly proportional. If the speed is too fast, too little glue glue was guttate will appear. Another problem is that glue the tail with the tail of the situation appears, in this case, but also to view from the coater nozzle and the material, if the distance between the nozzle and the material too close, there will be the tail section tailing phenomenon, whether because if excessive amount of glue cause streaking away from normal inspection, and if they are not, it is because you want to see if the glue is too thin, and if this is the case, the proposed replacement glue.
Understanding the above, we must control the distance well coater between nozzle and material, if not because of the problem of distance, and then view the other place if there is a fault.
