Introduction To The Basics Of Gold Zip Puller

In the garment industry, pull head although small, but plays a big role
The Gold Zip Puller has two entry ports and a meshing outlet, upper plate and lower plate. The upper plate is connected with the lower plate through a core. The inner side of the lower plate of the pull head for nylon zippers has upper tendons and lower tendons.
Gold Zip Puller is available in a wide variety of zipper types: metal chain puller, resin (nylon) chain puller, plastic steel chain puller, seal chain puller, anti-load chain puller, film plastic sealing puller, etc.
Why these types of zipper heads? Is it possible to unify to none?
Generally speaking, the pull head is not universal, that is because different varieties of zippers their width and thickness is not the same. As shown in the figure A and B, in order to match the zipper, the sizes of A and B are different on the nylon zipper, plastic steel zipper and metal zipper respectively.
Nylon zipper head: pull head body overall shape is generally semicircular. Because only one side of the nylon zipper has teeth, so the fabric seam and one side is wider, one side is narrower.
Metal zipper head: The whole zipper head has edges or edges are obvious, because both sides have teeth, so the side fabric seam on both sides of the same width.
Plastic steel zipper head: the whole zipper head is semi-circular arc or butterfly shape. Since there are teeth on both sides, the side seam is the same width on both sides
