Plastic buckets are round plastic containers. They are designed in many sizes and configurations and can be engineered to varied specifications. Most other kinds of plastic containers share plastic buckets’ ambiguity of purpose; the words “plastic buckets” are not prescriptive of a specific design or function but descriptive of a general concept.

Design of Plastic Bucket
Plastic buckets generally tend to be:
- Round Containers
- Small to Medium Size
- Used for Transportation or Storage
- Range of Materials in Small Quantities
Plastic buckets are smaller than plastic tubs and tend to be larger than plastic bottles, though there are exceptions. They can be large enough to transport emulsifiers on a commercial or industrial scale, or they can be small enough for making beach sandcastles.
The lifespan of some plastic buckets might involve both, given their reusability, lightweight, and low cost, though this would be more likely if the bucket originally contained consumer products. Most plastic materials’ ease of recyclability makes them attractive materials for container construction because many containers are only needed once for the transportation or delivery of a product. Virtually every industry makes some use of plastic containers, and many of those containers are designed as buckets.
Manufacturing Plastic Buckets
The manufacture of all plastic containers involves either a blow molding or injection molding machine. Many buckets are made out of high-density polyethylene. HDPE is a durable, non-reactive thermoplastic that resists impact and inhospitable climates during transit or storage, which in the beginning of the molding process is called stock.
In the blow molding process:
- Raw HDPE resin is loaded into a hopper.
- The hopper directs the stock into a conveyance channel, where a large screw forces the stock toward a mold.
- As the screw turns, the combination of friction and pressure heats the stock.
- This heating, combined with extra heat provided by heating elements along the channel, heats the stock to the point of liquefaction.
- The liquefied stock enters a mold cavity and takes its shape.
- Compressed air is then blown into the cavity, hollowing out the middle of the plastic mold.
- Once the molding process is finished, the product is allowed to cool and harden.
- It is then ejected from the mold, cleansed of imperfections (if they are present), and either shipped or sent for additional processing.
