Cap & Closure Moulds

Injection moulds for bottle caps and closures: water and CSD caps, flip-top caps, oil and sauce caps, pharma closures and consumables. They are hot-runner, multi-cavity moulds, made to fit your bottle neck and your machine.

Closures we tool

A cap for every bottle

  • Plastic screw caps: water (PCO 1810/1881, 29/25, 30/25), CSD, juice and dairy, with tamper-evident bands.
  • Flip-top caps: shampoo, lotion, sauce and personal-care dispensing closures.
  • Pharma consumables: pharmaceutical closures, droppers, measuring caps and medical consumables.
  • Other closures: sports caps, edible-oil caps with pourers, 5-gallon caps and specialty closures.

Built to seal, run fast and last

  • Thread release: stripper-ring, unscrewing (motor or rack driven) or collapsible core, whichever suits your thread.
  • Hot runner for runner-free, balanced filling and a clean gate on the cap top.
  • Hardened, polished cavities for consistent dimensions and long life.
  • Fit with the bottle: designed against your bottle neck, so the seal is reliable at capping speed.
  • Matching lines: slitting and folding for tamper bands, lining, printing and vision inspection.

Running very high volumes of one cap? Compare cap compression moulding (CCMM), or read compression vs injection for caps.

Frequently asked questions

Which cap mould type do I need: unscrewing, stripper or collapsible core?

Stripper-ring moulds are the simplest and fastest for caps with shallow, flexible threads such as many water caps. Unscrewing moulds are needed for deep or rigid threads. Collapsible cores suit internal undercuts. We recommend the design after reviewing your cap drawing.

Can you make a cap that fits my existing bottle?

Yes. Send us the bottle neck (or a sample bottle and cap). We match the thread, sealing and tamper band so the cap seals properly on your capping line.

How many cavities can a cap mould have?

It depends on cap size and machine tonnage, from a few cavities for large or complex closures up to high-cavitation moulds for small water caps. We size the mould together with the injection moulding machine.

Do you also supply compression moulds for caps?

Yes. For very high-volume caps we supply complete cap compression moulding lines, including the mould sets.
