Let’s dive into the key features and technical specifications that make this mold stand out in the competitive market.
Key Features & Benefits
- Premium S136 Steel Construction – Offers excellent wear resistance, corrosion resistance, and polishability, ensuring smooth cavity surfaces and extended mold lifespan.
- Hot Runner System – Reduces material waste, shortens cycle times, and maintains uniform melt temperature for consistent cap quality.
- 16 Cavities (1×16 Layout) – High productivity per shot, ideal for mass production of standard bottle caps.
- OEM Customization Available – We can adjust cavity design, thread type, gate location, and cooling layout according to your specific cap dimensions and material.
- TS16969 Certified Production – Our manufacturing processes follow strict quality management standards (TS16969), ensuring reliable mold performance.
- Efficient Cooling System – Optimized cooling channels reduce heat buildup, shorten cycle times, and improve part dimensional stability.
- Easy Maintenance – Modular design with interchangeable inserts allows quick cavity replacement and simple cleaning.
Technical Specifications
| Mold Material | S136 Stainless Steel (hardened to HRC 48-52) |
| Number of Cavities | 1×16 (16 cavities) |
| Runner System | Hot Runner (no cold runner waste) |
