Slider is the moveable element that open and close the zipper. It composes of ¡§body¡¨, ¡§puller¡¨, and ¡§bridge¡¨. 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. Sea-Cheng offers variety of fancy puller and also at the same time is willing to cooperate with customers to open new slider and puller mold in order to fit specific purpose.
