Pins on a separate zipper

December 26, 2019

Based on the manufacturing material, pins can be categorized into:Zin alloy pins and POM pins
The first type of pins which is primarily manufactured out of zinc alloy is mainly adopted for metal zippers and nylon coil zippers.

POM pins are manufactured through injection molding. POM is the same material that is used for producing the teeth elements of delrin zippers. These pins are mainly adopted for delrin zippers and nylon coil zippers, though few of them can also be found on metal zippers. When POM pins are attached to nylon coil zippers, these zippers are referred to as nylon coil zippers with plastic stoppers.

Classification Based on Functioning
Based on functioning, pins can be classified in accordance with the types of zippers.
One way separating zippers: The pin and insert box are installed on the different sides of a zipper, forming a secure connection with the single slider passing along them.
Two way separating zippers: There are two pins mounted onto these zippers that accommodate easy movement. They are referred to as mobile pin and fixing pin respectively, accompanied by 2 zipper sliders.
Easy release zippers: The pins used for these zippers differ slightly from the regular pins in structure. They are mainly used for the sportswear, allowing easy and quick removal from the wearers.
Classification Based on the Handed Version

Based on whether they are attached on the right or left side of a zipper, pins can be grouped into:
Left-sided pins
Right-sided pins
When the pin is installed on the left side, the insert box will be mounted on the right side to form a complete stop mechanism, and vice versa. You may learn more in this post: What’s The Difference Between Right & Left-Sided Insertion Pins.
