Description

Slider tab injection molding device for slide fasteners}

The present invention relates to a device for injection molding a pull tab of a slider for a slide fastener, and more particularly, to a device for automatically injection molding synthetic resin into a pull tab.

Slide fasteners are attached to the opening and closing parts of various clothing, bags, shoes, etc. to maintain airtightness while easily opening and closing. The slider of such a slide fastener is composed of a slider body that is inserted into both fastener chains to separate and combine them, and a traction tab (handle) attached to the middle linker so that the slider body can be easily moved.
