This 24-cavity cap mold is designed for bottle caps, water bottle cap sealing, and drinking water closure production. It is built for stable output, consistent cap quality, and reliable performance in long production runs.
In multi-cavity cap molding, the key is not just one good cavity, but stable performance across all 24 cavities. Better cavity-to-cavity consistency helps reduce cap variation, improve sealing results, and lower adjustment work during production.

This mold is developed for cap projects where repeatability and balanced cavity performance matter. Stable cavity conditions help support smoother production and more predictable output.
This bottle cap mold is suitable for:
bottle caps
water bottle cap sealing
drinking water closures
These applications require reliable sealing surfaces, consistent thread details, and stable dimensional control.
Critical wear areas can be designed as replaceable inserts, making maintenance easier and more practical. This helps reduce downtime and supports longer mold service life.
For bottle cap and water closure molds, the sealing area, thread-forming area, and fitting details are critical. Small differences in these areas can affect cap fit and sealing performance.
By improving the machining and control of core inserts, cavity inserts, and key forming areas, the mold can achieve better cavity-to-cavity consistency. A practical insert structure also helps extend tool life and makes maintenance more efficient.

This 24-cavity cap mold is widely used for:
bottle cap molds
water bottle cap sealing molds
drinking water closure molds
precision plastic cap production
It is suitable for projects that require repeatable production, stable sealing performance, and reliable long-run mold operation.
At SENLAN, we focus on cap mold projects where precision, consistency, and practical production performance matter.

It is used for bottle caps, water bottle cap sealing, and drinking water closures.
Yes. It can be customized based on drawings, samples, and project requirements.
By controlling critical inserts and forming areas more carefully, the mold helps improve cavity-to-cavity repeatability.
Replaceable insert design makes maintenance easier and helps reduce unnecessary rework on the full mold.
