Overview

A zipper is a system: chain, tape, slider, stops and end treatment must match the application. Most field failures come from a mismatch between these parts or from a process step that was skipped — not from the teeth themselves.

Production Notes & QC Checkpoints

What decides whether this product performs in the field — and what to verify before each shipment:

Checkpoint	What goes wrong	Verification
Specify the full construction	Chain type, size, tape width, slider type, stop type and end treatment (closed-end / open-end / two-way) all need to be on the PO.	Match every PO line against the approved sample
Stop strength	Top and bottom stops fail before the chain does. Confirm stop type and strength for the load.	Stop-strength test per order requirement
Colour and finish	Tape dye lot and metal plating lot must be kept together; mixed lots show on the finished product.	Golden sample comparison under D65
Packing and transport	Bulk packing without support deforms sliders and kinks chain. Confirm packing method for long zippers.	Sample check after transport
Traceability	Keep batch references per carton so defects can be traced back to a production run.	Batch label on every carton

Buyer FAQ

Q1. How do I specify a zipper correctly?

State chain type and size, tape width and colour, slider type, stop type, end treatment (closed, open, two-way) and the length with tolerance. A sample or drawing makes it unambiguous.

Q2. What is the difference between closed-end and open-end?

Closed-end zippers are joined at the bottom and are used for bags and pillow covers. Open-end zippers separate completely and are used for jackets. Two-way zippers open from both ends.

Q3. Which standard applies to my order?

Common standards are ASTM D2061 (US), BS 3084 (UK) and QB/T 2171–2173 (China). Name the standard and acceptance values in the PO so test reports can be issued against it.

Q4. Can you match tape colour to my fabric?

Yes, against a swatch or Pantone reference. Keep the approved sample; repeat orders are matched to it.

Q5. Do you supply zipper rolls or finished lengths?

Both. Continuous rolls suit automated cutting; finished lengths with stops and end treatment suit cut-and-sew lines that do not carry zipper machinery.
