During application, upper mould and bottom mold must dowel each other. It is one of the incorrect application practices in pounding machines having dowelling error is that claws are not tightly attached.
Moulds with faulty and incorrect adjustment will cause deformation of snap fasteners. In addition, incorrect moulds will cause deformations on the surface of snap fasteners, move dyes on dyed products off, crack coating in coated products.
When pounding impact of the machine is higher than normal, snap fasteners will be deformed, not attach to each other, tear and scratch.
When pounding impact of the machine is lower than normal, snap fasteners will not attach each other. Resistance of snap fasteners in low impact machines will be lower and tearing risk is higher.
Distance between lower mould and upper mould must be adjusted. After completing the work of snap fastener pressing, no distance must be left between snap fasteners and fabric.
MANNER OF APPLICATION Female part + fabric +claw or cover
Male part + fabric +claw
Snap fastener position attached after pounding process.
