Injection Moulds: Cap, Closure and Precision Tooling
Injection moulds machined in-house at AMAN - cap and closure tooling, hot-runner moulds, PET preform moulds and precision injection tooling. Hardened steel, multi-cavity, with spare cavities and inserts cut from the same drawings.

Cap and closure molds
AMAN builds injection cap and closure moulds in-house. The cap tooling is multi-cavity with hot-runner systems: heated manifolds and nozzles keep the melt balanced across cavities, eliminate cold-runner scrap and support the fast cycles closure economics demand. For two-color threaded caps the tooling registers the two shots accurately, so the colours meet cleanly and the thread stays true. Cavities are cut from hardened tool steel to hold their critical thread and sealing dimensions over long runs.
Because AMAN also makes the blow moulds and supplies the machines for the bottles, cap moulds can be matched to the mating bottle neck from the outset — thread pitch, sealing surface and fit engineered together rather than reconciled after the fact. See it running: two-color threaded cap and closure moulds built for a closures maker in Pakistan.
This page is the tooling listing. If you would rather start from the part you sell — the cap, the jar, the measuring cup, the preform — and watch the tool running at tryout, go to the injection mould manufacturer page.

Injection moulds built in China
AMAN has manufactured injection molding moulds in-house since 2007 — including PET preform moulds, cap moulds and precision plastic injection moulds. As an injection mould manufacturer that also supplies the injection molding machines, we guarantee the mould and the machine work together as one ready-to-run system.
Much of what leaves this workshop is closure tooling: multi-cavity cap and closure moulds with balanced hot-runner systems, including two-colour and threaded caps, cut from hardened tool steel so thread and sealing dimensions hold over long runs. We also build precision injection moulds for buckets, thin-wall parts and industrial components. PET preform tooling has its own page.
Every mould is precision-machined, polished and trial-run before delivery. Tell us your part drawing, neck finish, cavity count and output target, and our engineers will recommend and quote the right injection mould — on its own or as a complete machine-and-mould package.
