How do zipper functions affect the quoted price?

Q: How do zipper functions affect the quoted price?

Function changes price because it changes the number of parts and the precision of assembly. A basic auto-lock slider is the reference point. Adding a locking mechanism, a pin-lock, a reversible body, a two-way opener or a separator at the bottom adds components and assembly time, and the price rises step by step. A puller that is cast, engraved or plated costs more than a plain stamped puller, and a custom shape needs a mould. Tape treatment also counts: a water-repellent finish, a reflective yarn or a printed logo adds a process. Performance requirements such as a stated cycle life or a pull strength above the standard figure may require a heavier chain or a different slider, which changes the base specification rather than the option list. Ask for the quotation to separate the base zipper from each function so you can see the increment. Then decide which functions the garment actually needs; over-specifying is a common source of avoidable cost.
