Changzhou Hongxinyutai Precision Mold Co., Ltd., established in 2017, is a professional manufacturer specializing in high-precision injection molds. Leveraging our 1,000–3,000 square meter factory and a skilled team of 51–100 employees, we present our Two-Piece Bottle Cap Injection Mold with a 1×16 cavities hot runner system and premium S136 steel. This mold is engineered to deliver exceptional productivity, consistent quality, and long service life for bottle cap manufacturing.
Our mold meets the demands of high-volume production while maintaining tight tolerances and excellent surface finish. The 1×16 cavity design optimizes output per cycle, and the hot runner system minimizes material waste and reduces cycle time. We serve clients across North America, South America, Europe, Southeast Asia, Africa, Oceania, and the Middle East, and our products are shipped from Jiangsu, Shanghai, and Shenzhen ports.
