Zipper Slider

Slider is the moveable element that open and close the zipper. It composes of "body", "puller" and "crown". Most sliders are made of zinc alloy raw material. There are also sliders made of copper alloy, iron and plastic to fit specific purpose. When choosing the most appropriate slider to assemble onto the zipper, one needs to consider the four important elements:

(1) Zipper size and type,

(2) Locking function,

(3) Puller type,

(4) Surface treatment.
