Plastic Bucket Mould – Precision Injection Moulds for Round, Square & Paint Buckets
Introduction to Plastic Bucket Mould
Unique Mould engineers high-accuracy Plastic Bucket Mould solutions for household, industrial, paint and food-grade buckets. Built with premium tool steels and produced on advanced CNC, EDM and polishing lines, our bucket moulds deliver fast cycles, excellent surface finish, dimensional stability and long life. If you need dependable output with consistent part weights and clean stackability, our team in Kolkata is ready to support your production ramp.
How a Plastic Bucket Mould Works
In injection moulding, molten PP/HDPE flows into a precision-machined cavity via balanced runners and gates. Optimized cooling lines, hardened cores and wear-resistant inserts control shrinkage and improve ejection, giving you smooth walls, accurate handles and tight-sealing lids. Our DFM review covers draft, ribbing, IML/emboss options and handle hinge geometry to maximize durability and cycle efficiency.
Types of Plastic Bucket Mould We Build
- Round bucket moulds (5L, 10L, 15L, 20L, 25L variants) with reinforced rims.
- Square/rectangular bucket moulds for space-efficient stacking and transit.
- Paint bucket moulds with tamper-evident lids and clean pour lips.
- Food-grade bucket moulds compatible with IML labels and smooth inner finish.
- Heavy-duty industrial bucket moulds with metal/plastic handle integration.
Key Features of Our Bucket Moulds
- High wear resistance with hardened cavities, cores and bushings.
- Optimized cooling design for shorter cycle time and lower energy use.
- Balanced runner/gate system for uniform filling and minimal warpage.
- Rapid ejection with multi-point ejectors and smooth release surfaces.
- Customization: volume, wall thickness, logo embossing and IML readiness.
Applications
- Paints, coatings and chemicals requiring secure lids and clean dispensing.
- Food, dairy and bakery items with hygiene-friendly smooth surfaces.
- Construction and hardware storage with heavy-duty handles.
- Household utility buckets, mop buckets and multipurpose containers.
Why Choose Unique Mould for Plastic Bucket Mould
- Accurate, repeatable parts that stack reliably and pass fit tests with lids.
- Lower maintenance due to robust steel selection and precise hardening.
- Faster project onboarding with DFM support and clear QC documentation.
- Consistent cycle times and reduced scrap through optimized cooling and vents.
Process & Quality
Every Plastic Bucket Mould project includes CAD/CAM, flow simulation review, high-speed machining, EDM finishing, bench fitting and full trial runs. We record part dimensions, weight, cycle time and visual quality. Tool books include steel certificates, heat-treatment records and maintenance guides to help your team run stable, long-life production.
Maintenance and Handling Tips
- Apply rust preventive after trials and store in a dry, controlled environment.
- Inspect gates, vent lines and ejector pins regularly to avoid flash or drag.
- Use recommended clamp force and barrel settings to protect cavities and cores.
- Clean cooling channels periodically to maintain cycle time.
- Follow a preventive maintenance log for bushings, guides and hot-runner parts.
