12-cavity PP Cap Mould
liquid PP Cap Mould for cosmetic
This 12-cavity PP cap mould is a high-efficiency injection tool engineered for medium-batch production of 28mm standard PP beverage caps, yielding 12 identical caps per cycle with a stable molding cycle of 8–12 seconds. Adopting Huangyan’s classic balanced cold runner design, it ensures uniform melt distribution across all cavities, reducing runner scrap to ≤2.0%. Built with Huangyan-standard P20 pre-hardened steel (HRC 28–32) for the mold base and S136 stainless steel (HRC 48–52) for cavity inserts, it meets strict local precision requirements (dimensional tolerance ±0.02mm) and delivers a service life of 2–4 million shots. Compatible with 100–160T clamping force injection machines, it is the ideal choice for small-to-medium bottled water and juice plants pursuing cost-effective, stable cap production.

Thismulti-cavity 12-cavity PP cap mould is a high-efficiency injection tool engineered for both medium-batch production of 28mm standard PP beverage caps and liquid PP cosmetic caps. It leverages advanced hot-runner technology (with an optional classic balanced cold runner design) to ensure uniform melt distribution across all cavities, reducing runner scrap to ≤2.0% and enabling a fast cycle timeof12 seconds (range: 8–12 seconds) per production run, yielding 12 identical caps per cycle.
Constructed with Huangyan-standard P20 pre-hardened steel (HRC 28–32) for the mold base, cavity inserts can be specified with S136 stainless steel or premium 2316 stainless steel—acorrosion-resistant alloy that excels in high-hygiene applications like cosmetic packaging, ensuring a service life of 2–4 million shots and meeting strict local precision requirements (dimensional tolerance ±0.02mm). Equipped with a precision living hinge mechanism, it is optimized for caps requiring flexible, durable hinge structures, making it ideal for both beverage closures and liquid PP cosmetic caps. Compatible with 100–160T clamping force injection machines, this customizable mould is the ideal choice for small-to-medium bottled water, juice plants, and cosmetic packaging manufacturers pursuing cost-effective, stable cap production.
