This 8CAV screw cap mould is used for high-volume plastic lids where smooth thread engagement and dependable sealing are required in every shift.
The project can be configured around cap diameter, thread pitch, sealing ring and matching container neck dimensions. The reference setup is matched with a 300T high-speed injection molding machine and targets cycle time within 6.5 seconds.
Thread fit, sealing land flatness, demolding method and dimensional stability all decide whether caps close smoothly without stripping threads or leaking during transportation.
Before final tooling release, Hengqi reviews cap torque requirement, matching container sample, resin shrinkage behavior, expected output and automation method to lock runner type, cooling strategy and ejection structure.
Yes. Thread pitch, start angle, cap diameter and sealing profile can be matched from your drawing or physical neck finish sample.
Yes. Tamper-evident band and anti-backoff details can be integrated after reviewing your closure design and opening-force target.
Share cap drawings or samples, container neck data, resin type, annual volume target, machine tonnage and any leak-test or torque requirement.
Send the product drawing, sample weight, cavity target, machine tonnage, material, and expected cycle time. Hengqi can review the tooling structure and reply with a practical proposal for production.
