Bespoke Bottle Caps — Custom Zamac Perfume & Wine Caps Made to Your De

Launching a fragrance or wine line? The cap is the first thing your customer touches.

GuanChengXin is a Zamak (zinc alloy) cap specialist from Dongguan, China — nearly 20 years of die-casting experience, custom molds for 100+ brand partners, and 80% of customers in Europe and the USA. We ship worldwide.

Why brands choose Zamac over wood or plastic:
- Real metal weight — on shelf, heavy reads premium
- Deep engraving and 3D relief logos that hold at volume
- Gold, rose gold, chrome, antique and matte finishes — not possible on plastic

Send your bottle neck spec and target look; we'll check the fit and send samples before production.
