Changzhou Hongxinyutai Precision Mold Co., Ltd. takes pride in manufacturing high-performance injection molds tailored for the packaging industry. Our OEM Two-Piece Bottle Cap Injection Mold is engineered with precision, featuring a 1×16 cavity layout crafted from premium S136 steel and built under the rigorous IATF 16949 quality management system. This mold is designed to produce consistent, high-quality two-piece bottle caps at an optimal cycle time, ensuring your production lines run efficiently without compromising on cap integrity or visual appeal. Backed by our experienced team of 51–100 professionals and a dedicated factory spanning 1,000–3,000 square meters, we deliver tooling solutions that meet the demanding requirements of global markets.
This injection mold represents the perfect balance of durability, precision, and productivity. Whether you are packaging beverages, pharmaceuticals, or personal care products, our mold guarantees reliable performance over millions of cycles. Let us walk you through its key features and technical specifications.
Key Features & Technical Specifications
- High-Cavitation Design: 1×16 cavities significantly boost output per shot, reducing cost per part and improving overall production efficiency.
- Premium Mold Steel: Constructed entirely from S136 steel (DIN 1.2083), known for excellent corrosion resistance, high hardness, and superior polishability – ideal for mirror-finish cavities required for glossy caps.
- Two-Piece Cap Geometry: Engineered specifically for two-piece bottle cap designs (inner seal + outer shell), incorporating separated cooling channels for each component to ensure uniform shrinkage and dimensional accuracy.
- IATF 16949 Certification: Our entire manufacturing process follows the automotive-grade quality standard, guaranteeing traceability, defect prevention, and continuous improvement in mold production.
- Optimized Cooling System: Strategically placed cooling circuits minimize cycle time while maintaining stable mold temperature, resulting in faster production and fewer rejects.
- OEM Customization: Molds are fully customizable according to your cap design, including thread type, tamper-evident features, and specific gate locations (cold runner or hot runner systems available).
- Precision Ejection: Advanced ejector pin layout and stripper plate (if required) ensure smooth part release without damaging the delicate cap features.

Beyond the table, our mold offers additional benefits that directly impact your bottom line:
- Reduced Downtime: The robust S136 steel construction and precision machining minimize wear, allowing continuous operation in high-volume production environments.
- Better Part Consistency: Each cavity is individually balanced (flow and cooling) to ensure all 16 caps are identical within tight tolerances (±0.02 mm on critical dimensions).
- Ease of Maintenance: Modular design enables quick replacement of worn components (core pins, cavity inserts) without removing the entire mold from the press.
- Wide Material Compatibility: Works with PP, HDPE, LDPE, PET, and other common cap materials with no modification needed.
- Compliance & Safety: Designed to meet global food contact and pharmaceutical packaging standards (upon request).
