Plastic paint bucket production line is a manufacturing setup used to produce plastic containers by using injection molding machine. It mainly includes the following 7 steps.
Step1: Material preparation
Step2: Melting and mixing
Step3: Injection
Step4: Cooling
Step5: Mold opening and ejection
Step6: Trimming and Finishing
Step7: Labeling and decoration (Optional)

20L Plastic paint bucket production line
Plastic paint bucket injection molding machine is a type of injection molding machine specially designed for manufacturing plastic paint buckets.
The injection unit of this machine heats and melts the plastic pellets and injects them into the mold, while the clamping unit holds the mold in place and keeps it closed during the injection process.
Material preparation
- Selection of Raw Material: The main materials used to produce plastic drums are polypropylene (PP) or high-density polyethylene (HDPE), and both of which are thermoplastic resins.
- Pellet Feeding: Plastic pellets are loaded into the hopper of the injection molding machine.
Melting and mixing
- Heating: The machine heats the plastic pellets in the barrel, where they melt into a viscous liquid.
- Mixing: A rotating screw mixes the molten plastic to ensure uniform consistency and temperature.
Injection of plastic paint bucket production line
- Filling the mold: The molten plastic is injected into the 20L bucket mold cavity through a nozzle under high pressure.
Cooling of plastic paint bucket production line
- Solidification: The plastic cools and hardens inside the mold to form the bucket shape.
- Temperature control: A cooling system (often water or air-cooled channels) ensures even cooling to avoid defects like warping.
Mold opening and ejection
- Mold separation: The clamping unit opens the mold once the plastic has solidified.
- Ejection: Then ejector pins or plates push the formed bucket out of the mold.
