Provided is a polyamide resin composition for a slide fastener that includes at least one polyamide resin and reinforcing fibers, wherein a total mass of the polyamide resin and the reinforcing fibers accounts for 90% by mass or more of the composition; wherein poly(m-xylylene adipamide) (MXD 6) accounts for 60% by mass or more of the polyamide resin; wherein reinforcing fibers account for 45 to 70% by mass of the total mass of the polyamide resin and the reinforcing fibers; wherein both first reinforcing fibers having a fiber diameter of from 5 to 7 m and second reinforcing fibers having a fiber diameter larger than that of the first reinforcing fibers by more than 2 m account for 90% by mass or more of the reinforcing fibers; and wherein the first reinforcing fibers account for 20% by mass or more and less than 50% by mass of the reinforcing fibers.

A dispatch system and a dispatch method for manufacturing mold are provided. The dispatch system includes a control unit, a mold material storage unit, a processing cutter storage unit, an object pick-and-place and transfer unit, a mold processing unit and a mold product storage unit. The mold material storage unit includes many unprocessed mold materials. The processing cutter storage unit includes many processing cutters. The object pick-and-place and transfer unit is electrically connected to the control unit and disposed between the mold material storage unit and the processing cutter storage unit. One of the unprocessed mold materials and one of the processing cutters are transferred to the mold processing unit by the object pick-and-place and transfer unit, the unprocessed mold material is processed to form a mold product by the mold processing unit, and the mold product is transferred to the mold product storage unit.

A waterproof zipper is provided with two halves, each including a half tape member and a row of protruding teeth along an inner edge of the half tape member; and a waterproof layer is secured to an inner surface of the halves. A process of manufacturing the waterproof zipper is also provided, including the steps of: (a) guiding the waterproof layer to a position above the two halves on a continuous flow production line, each half having a half tape member and a row of protruding teeth along an inner edge of the half tape member; (b) coating a waterproof layer on a releasing layer; (c) drying both the waterproof layer and the releasing layer in an oven.

A thermal plastic elastomer injection mold comprises: a mold base, formed with a platform having a top surface thereof formed with an arc-shaped surface adhered with a pair of support-tapes of a slide fastener and formed with an elongated arc-shaped ridge having a wedge-shaped tip thereby being able to be stably moved into a gap between the pair of support-tapes and a surface of the arc-shaped ridge is formed with a thermal plastic elastomer injection port connected to at least one extruder; and a thermal plastic elastomer, extruded out from the at least one extruder and passing the thermal plastic elastomer injection port so as to be injected into the gap and slits inside two rows of coupling elements disposed at inner edges of the pair of support-tapes, wherein the slide fastener is formed with a water impervious structure after the thermal plastic elastomer inside the gap is cut.

Zippers components such as a traditional pin and box assembly may be affixed to zipper stringer tapes by a simple injection molding process. When a non-traditional magnetic alignment assembly is used in place of a traditional pin and box assembly, other means are needed to adequately affix the components of the magnetic alignment assembly to the zipper stringer tapes in order to provide a durable finished zipper.
