Plastic buckets are produced by injection moulding — thermoplastic granules (typically polypropylene or HDPE) are melted, injected into a mould at high pressure, cooled, and ejected as a finished or near-finished bucket. The mould determines the bucket's dimensions, wall thickness, stacking geometry, handle lug positions, and surface finish. For production of 5–25 litre buckets, machine clamping forces typically range from 300 to 800 tonnes depending on the bucket diameter and wall thickness. A production cell consists of the injection moulding machine, the bucket mould (typically a single-cavity or 2-cavity hot runner tool), an IML (in-mould labelling) unit if labelled buckets are required, and a robot/conveyor for part removal and stacking. Cycle times for a standard 5-litre PP bucket (wall thickness approximately 2.5mm) are typically 8–16 seconds. Output per hour ranges from approximately 180–450 buckets per hour per cavity depending on material, wall thickness, and cooling efficiency.
