HDPE Pull Ring Bottle Cap Injection Molding Machine
A fast injection molding machine for pull-ring water-bottle lids and closure caps in HDPE. A multi-cavity hot-runner mould and quick cycling suit the high counts caps demand.
Overview
Pull-ring caps and closures are small, detailed parts produced in huge numbers, so this machine combines rapid injection cycles with a multi-cavity hot-runner mould to mould many caps each shot. The hot runner keeps every cavity filling cleanly so tamper rings and threads form correctly, and servo or electric drive holds the pace while limiting energy use. CE-standard build and matching AMAN tooling make it ready for dedicated closure production.
Key features
- Fast cycles for high cap counts
- Multi-cavity hot-runner mould per shot
- Forms pull rings and threads cleanly
- Servo or electric drive limits energy use
Application
HDPE pull-ring lids, closures and water-bottle caps for beverage and packaging lines requiring high output.

One machine covers a range of sizes: you only change the mould to make a different product. The machine must be selected according to the LARGEST product you plan to make — running a small product on a large machine is possible, but you lose some efficiency and some material. Send us your smallest and your largest product (size and weight) and we will confirm whether one machine is enough.
Order the cap mould with this machine and we make it in our own workshop, then ship machine and mould as one set, tested and tuned together. The mould itself takes 40–60 days from approved drawings. Send your part drawing and we quote the machine together with the mould.
Each machine is configured to your container; the final specification is written into your quotation.
