Learn More →Engineered for ultra‑high‑volume production, our water and beverage cap moulds set the benchmark for speed, reliability, and cap quality.
Optimized cooling and hot runner systems achieve cycle times as low as 4.5 seconds.
Cavity‑to‑cavity variation within ±0.01 mm ensures consistent cap dimensions.
Moulds fully compliant with international neck finish standards for global compatibility.
YUDO / Mold‑Masters systems with individual nozzle control for balanced filling.
S136 mirror steel prevents rust in high‑moisture production environments.
Modular core/cavity inserts allow easy upgrade from 48 to 72 cavities.
Our water cap moulds feature balanced hot runner layouts with individually controlled nozzles to eliminate material waste. Conformal cooling channels maintain ±1°C temperature uniformity across all cavities, ensuring rapid solidification and minimal warpage.
We use a robust stripper plate design for PCO 1881 and similar closures, ensuring smooth cap release without deformation. For tamper‑evident caps, a two‑stage ejection sequence protects the fragile tamper bridges.
