FAQs

Question
Why do metal buttons turn black and develop oxidation spots after storage, and how can we prevent this issue?

Prevention Tips:

  • Choose High-Grade Finishes: Opt for quality electroplating with a durable clear lacquer or electrophoretic topcoat (e-coating) verified by salt spray testing.

  • Store in a Dry, Cool Area: Keep storage humidity below 50% RH and place boxes on elevated pallets away from damp walls and floors.

  • Use Anti-Tarnish Packaging: Pack buttons with pH-neutral, sulfur-free paper, sealed polybags, and silica gel desiccants. Ensure handlers wear cotton gloves during packing.


What is the MOQ for custom metal buttons, and do you support small-batch sampling service?

Yes, we fully support small-batch sampling and flexible ordering options to help you develop and test new collections before mass production.

  • Sampling / Prototyping: We offer custom prototyping and sample runs (typically starting from 50–100 pieces per design/mold) so you can review sizing, engraving details, weight, and electroplating finishes on actual garments.

  • Mass Production MOQ: For custom die-cast zinc alloy or stamped brass buttons, our standard minimum order quantity is typically 1,000 to 3,000 pieces per style/finish, depending on design complexity and production technique.

(Note: Custom logo molds require a one-time mold fee, which is refundable once bulk order quantities reach agreed volume tiers. Contact our sales team with your artwork or tech pack for exact quotes and lead times.


A zipper made of or coated with nickel caused an allergic reaction upon direct contact with skin. How can I avoid this?

When a silver-colored metal zipper is required, choose an aluminum zipper. We offer a variety of products which meet European Nickel Directive (now part of REACH). Please ask your CPP representative for “N-ANTI” or “anti-nickel” products.

How can we reinforce metal buttons on garments to stop them from falling off under frequent pulling?

Ensuring strong button attachment requires reinforcing the fabric foundation, selecting the right hardware dimensions, and calibrating attachment settings.

Key Best Practices:

  • Add Fabric Interfacing & Washers: Fuse durable interfacing inside the placket/waistband. For snap buttons and jeans tacks, add reinforcement washers (gaskets) or clear backer buttons on the reverse side to distribute pulling force and protect fabric fibers.

  • Match Post Length to Fabric Thickness: Ensure the tack/prong length matches the compressed fabric thickness. A post that is too short will not clinch securely, while a post that is too long will bend or crush the fabric.

  • Use Heavy-Duty Thread with a Thread Shank: For sew-on buttons, use bonded polyester or core-spun thread. Allow a slight clearance (thread shank) so the button can pivot naturally without shearing the stitches.

  • Calibrate Attachment Dies & Pressure: Regularly align and calibrate pneumatic attaching machines to avoid over-crimping (which cuts fabric yarns) or under-crimping (which leaves buttons loose).

  • Verify with Pull Testing: Test attachments with a calibrated tensile pull-tester to ensure they meet global safety standards (minimum 90 N / 20 lbs pull force holding for 10 seconds).
