It groups slider pull-off, stop holding, chain crosswise strength and pull-off force, each with its own fixture and speed.
Nylon coil is light, flexible and curved-seam friendly; molded resin is stiffer, more abrasion resistant and visually bolder.
Dimensional tolerances, pull and stop strength, reciprocating life and colourfastness, each with its own acceptance table.
Two-way zippers use opposed sliders so a coat or bag can open from either end; slider type and parking positions must be specified.
Repeated laundering exposes metal parts to detergent, water and heat. Corrosion first appears at scratches and cut edges.
Skipped molded teeth usually come from short shots, mold wear or a worn slider; a repeating gap points to molding, a random gap to damage.
The declaration must name each part, the substance, the CAS number and the concentration, and state the candidate list version used.
Grinding is metal or moulded parts rubbing under load. Locate whether it happens on close, on open, or only at one point of travel.
Stock components run about two to four weeks; custom dyeing or new tooling adds weeks. Ask for staged dates counted from sample approval.
Metal zipper MOQ is set by plating and casting batches plus tape dyeing, so confirm whether the minimum applies per style, per color or per shipment.
Coated zippers apply PU directly to the tape (about 3,000-10,000 mm); laminated zippers bond a TPU film for higher, more uniform protection.
