CAPMOULD
Precision injection moulds for sport caps, push‑pull closures, and complex combination caps. Leak‑proof, durable, and designed for high‑output assembly lines.
Request a Quote NowThree core mould categories for multi‑functional closures — sport caps, push‑pull, and complex combination assemblies.
For water and sports drink bottles. One‑hand operation, leak‑proof valve, 48 cavities, cycle time 6.2s.
Flip‑top + tamper band, or disc‑top + overcap. Two‑shot or assembly‑ready, up to 32 cavities.
Dual‑material caps for premium look and function. Rotary platen or core‑back design, 24‑48 cavities.
Functional caps require precise interaction of multiple parts. Our moulds deliver flawless assembly fit and reliable end‑user performance.
Micron‑level alignment ensures perfect fit between cap body, valve, and overcap.
Optimized silicone valve geometry prevents leakage during sports use.
Push‑pull and flip‑top mechanisms engineered for consistent torque and tactile feedback.
Cavity variation < ±0.01 mm guarantees identical cap performance across all cavities.
Conformal cooling and balanced hot runners achieve cycles as low as 6.2 seconds.
Interchangeable core/cavity inserts for quick product changeovers.
With over 15 years of specialization in cap mould engineering, we deliver precision tooling that exceeds industry benchmarks for complex multi‑component closures.
Our dedicated R&D team uses advanced Moldflow simulation and 5‑axis CNC machining to achieve ±0.005mm tolerances on every component. From two‑shot rotary moulds to intricate collapsible core designs, we engineer for flawless multi‑part assembly and reliable consumer use.
We exclusively use ASSAB S136, NAK80, and H13 tool steels with vacuum heat treatment to HRC 48‑52, ensuring 5M+ shot life. As a factory‑direct manufacturer, we control every process from steel procurement to trial run, delivering standard functional cap moulds in 30‑45 days.
