Casa • Industry FAQs • Why are boots being found with zips bursting open in the production process?

Check that there is no damage being caused to the slider by the toe / heel pressers or side pushers on the soling process. Check that the pullers are not being trapped in the conveyor belts on the drying tunnels so damaging the sliders. Check that the teeth are not being damaged through the use of hammers / special implements to pull down the zip with high force during the process of removing the last at the end of the line as this can bend the slider. Check that there is no glue in the teeth of the zip or inside the slider.
