Metal/Plastic/Nylon Zipper Sliders: Selection Criteria

Zipper Sliders

Zippers have been extensively applied to numerous industries, ranging from apparel, bags, backpacks, luggage to tents. These humble accessories are taking centerstage due to their functionality and efficiency, along with the fashion statement they make. However, a zipper without a proper slider is rendered useless, regardless of its utilitarian function or aesthetic appeal.

The selection of sliders is dependent on lots of factors, including the type of zippers, zipper gauge, type of fabrics, application scenario, just to name a few. Basically, sliders can be segmented into 3 categories based on the types of zippers available, covering metal sliders, plastic sliders and nylon sliders. Below is the application scenario of different types of sliders based on the zipper gauge and locking mechanism.

The gauge of metal sliders ranges from 3# to 10#. Non lock and auto lock sliders can be paired up with metal zippers in different gauges. Also, pin lock sliders that further fall into the semi-auto lock classification are suitable for small-sized zippers. Basically, the smaller the zipper gauge, the lighter the fabrics these zippers can be sewn onto.

Likewise, non lock and auto lock sliders can be paired up with plastic zippers in different sizes. Additionally, plastic zippers which are available in multiple teeth and colors can accommodate more types of sliders. The larger the zipper size, the heavier the fabrics these zippers can be attached to.

The gauge of nylon sliders ranges from 3# to 10#. Similar to its counterparts, nylon zippers in different gauges can be paired up with non lock and auto lock sliders. Non lock, auto lock and pin lock sliders work for nylon zippers with/without cord. Additionally, invisible sliders can only accommodate small tear-drop pullers due to the special design of these zippers.

Closed End Vs. Open End Sliders
Sliders to be paired up with closed end zippers, open end zippers and two way open end zippers are different from each other. Closed end sliders feature lower and smaller tape gap, which ensures the proper performance of those zippers that are attached to the luggage and bags when they are subjected to special applications, and prevents the teeth aligned on both sides from disengaging unexpectedly when the zipper is zipped up. The larger the tape gap, the higher the chances of disengagement of both halves along the zipper chain. In comparison, open end sliders require higher and larger tape gap for the easier combination of the insertion box and pin to lock both sides into place. For two way open end sliders, the top stopper goes deeper into the inner cavity.
