20-25L HDPE Paint Bucket Injection Molding Machine
A horizontal injection molding machine built to mould 20L and 25L HDPE paint buckets and pails, plus matching crates, on a hot-runner tool. The wide platen and high clamping force handle thick-wall industrial containers in a single shot.
Overview
Paint pails this size need stiff walls and a clean rim for lid sealing, and the horizontal clamp delivers the tonnage to fill those thick HDPE sections evenly. A hot-runner single-cavity bucket mould fills the thick section evenly and eliminates cold-runner waste. The same platen also runs crate and pail tooling, so one machine covers a range of industrial packaging. AMAN supplies the matching mould and a turnkey setup on request. For other injection-moulded parts, see our full range of plastic injection molding machines.
Key features
- Moulds 20L and 25L HDPE buckets and pails
- Hot-runner single-cavity bucket mould, no runner waste
- Same platen runs crate and pail moulds
Application
20L and 25L HDPE paint buckets, pails and stackable crates for paints, coatings, chemicals and bulk industrial packaging.

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 injection mould for your part with this machine and we make it in our own workshop, then ship machine and mould as one set, tested and tuned together. 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.
