SHUANGHAO Machinery proudly presents our 8-Cavity Flip-Top Cap Mold—a precision-engineered tooling solution designed specifically for the efficient production of hinged flip-top caps. The 8-cavity configuration offers an ideal balance of productivity and flexibility, delivering 15,000-25,000 caps per day depending on cycle time and cap design . Perfect for medium-scale production, specialty cap runs, and manufacturers seeking reliable, high-quality flip-top closure tooling.
1. High-Efficiency 8-Cavity Design
Our 8-cavity mold delivers exceptional productivity:
Simultaneous production of 8 flip-top caps per injection cycle
Daily output of 15,000-25,000 caps based on 2.5-4 second cycle times
Ideal for medium-volume production, regional manufacturers, and diversified product lines
Lower initial investment compared to higher cavitation systems
2. Precision Flip-Top Hinge Engineering
The living hinge is the most critical feature requiring precision:
Optimized hinge cavity design ensuring consistent material flow for durable hinge performance
Precision cooling in hinge area preventing warpage and maintaining flexibility
Tested for thousands of open-close cycles without failure
Smooth operation with consistent snap and closure feel
3. Advanced Hot Runner System
Our 8-cavity mold features a precision hot runner system:
Individual temperature control for each nozzle, maintaining accuracy within ±1°C
Valve gate technology providing clean gate vestige with no tail trimming required
Balanced filling across all 8 cavities ensuring consistent cap weight and dimensions
Weight variation between cavities: Maintained below 0.2 grams
4. Premium Material Construction
Built for extended mold life and consistent performance:
| Component | Material | Hardness |
|---|---|---|
| Core and Cavity Inserts | S136 Stainless Steel | HRC 48-52 |
| Neck Rings | Nitrided Steel | HRC 45+ |
| Hinge Forming Inserts | Premium Tool Steel | HRC 50-55 |
| Mold Base | P20 / 4Cr13 | Pre-hardened |
Mold life: Engineered for 2-3+ million injection cycles with proper maintenance
5. Optimized Ejection System
Proper ejection is essential for flip-top caps:
Gentle ejection pins precisely positioned to avoid hinge contact
Synchronized ejection timing ensuring caps release cleanly without deformation
Optional robotic part removal for automated production
6. Efficient Cooling System
Rapid cooling for fast cycle times:
Spiral cooling channels ensuring uniform heat extraction across all cavities
Enhanced cooling in hinge and neck areas where material thickness is greatest
Balanced temperature distribution preventing warpage
