8CAV small cup with screw mould

This 8CAV small cup with screw mould is designed for projects where threaded closure quality directly affects leakage complaints and shelf presentation.

It is suitable for compact portion packaging programs that need repeat opening, stable cap engagement and uniform cup dimensions at high output.

Thread pitch standard, target cap torque window, wall-thickness tolerance, cup volume and drop-test requirements should be finalized before steel cutting.

Hengqi can evaluate your sample or CAD data and recommend cavity quantity, steel grade, cooling strategy and hot runner architecture for your annual volume target.

The mould structure focuses on sealing consistency, short cycle time and controlled dimensional variation so converters can reduce sorting losses and customer returns.

For high-volume portion cup programs, this helps procurement teams balance tooling cost, resin usage and long-run maintenance planning.

Small screw cups often fail from tiny thread, shrinkage or cap-fit changes, so buyers should define the matching cap, fill product, storage orientation and transport test before approving the tooling concept.

Hengqi can review whether the cup needs tamper evidence, sterilization compatibility, cosmetic surface quality or food-contact resin documentation before confirming steel and runner choices.

For medical or sample packaging, acceptance should include leak testing after cooling, cap torque checks and dimensional inspection across all cavities.

Because small threaded cups are often packed in bulk, sample approval should verify that cups separate cleanly, threads are not damaged by robotic pick-up and the matching cap reaches the same torque range on every cavity.

For sauce and cosmetic products, Hengqi recommends testing filled cups after cooling and transport simulation, because low-volume containers can leak from very small changes in rim flatness or thread shrinkage.
