Provided is a molded component for slide fasteners, which has a good balance between mechanical strength and platability. This molded component for slide fasteners is made of a resin composition that contains 30-50% by mass of a polyamide and 50-70% by mass of reinforcing fibers, with the total of the polyamide and the reinforcing fibers being substantially 100% by mass. In the resin composition, the polyamide has a weight average molecular weight of 30,000-80,000, and 50% by mass or more of the polyamide is composed of an aliphatic polyamide.

Slide fastener provided with molded component

A component for fasteners, including a molded component formed of a polyamide resin composition including reinforcing fiber, wherein a dyed layer being dyed inward from a surface of the molded component is disposed, and the thickness of the dyed layer is 30 to 100 &#x3bc;m.

Component for fasteners, slide fastener and method for manufacturing component for fasteners

Provided is a polyamide resin slider for a slide fastener which provides both strength and durability. The slider material is a polyamide resin composition that includes an aliphatic polyamide having a melting point of 220&#xb0; C. to 310&#xb0; C., an aromatic polyamide having a melting point of 230&#xb0; C. to 310&#xb0; C., and reinforced fiber; wherein the ratio of the aromatic polyamide present in the summed mass of the aliphatic polyamide and the aromatic polyamide is greater than or equal to 10% by weight and less than or equal to 50% by weight.
