Zamac Cap Blog & Insights

For 20 years, GuanChengXin (GCX) has focused on one thing: custom Zamac bottle caps done right. As a manufacturer — not a trading company — we design and produce custom perfume bottle caps and wine bottle stopper caps for fragrance brands, distilleries, and packaging distributors across Europe and the United States. Our 100+ employees operate more than 80 production machines, including zinc alloy die-casting machines, CNC lathes, and automatic polishing lines. From tooling and die casting to plating, polishing, and final inspection, every step stays inside our own factory — that is how we keep quality consistent and lead times under control. We handle both OEM and ODM projects. Send us your drawings for exact-to-spec OEM production, or share a concept and our design team will take it from 3D modeling to a finished mold. Samples are available for testing before mass production, and we confirm MOQ, tooling cost, and lead time clearly before you commit. Tell us your cap size, shape, and finish — our engineers will reply with a practical solution and a clear quotation.
