Applications
The Universal Workhorse: Industrial Bucket Production
Buckets are among the most versatile plastic products - used in construction, agriculture, food service, and every household. Our bucket moulds enable manufacturers to serve this massive global market.
Construction Industry Partnership
A major Southeast Asian construction company needed buckets that:
- Survived cement mixing without degradation
- Featured measurement marks for accurate mixing ratios
- Had reinforced handles for heavy loads
- 18-month bucket life (vs. 6 months with previous supplier)
- Accurate 1L measurement increments up to 15L
- Zero handle failures reported
Size Range for Every Application
| Size | Primary Use | Handle Type |
|---|---|---|
| 5L | Cleaning, painting | Plastic swing |
| 10L | General purpose | Metal wire |
| 15L | Construction, agriculture | Heavy-duty metal |
| 20L | Industrial, food service | Double metal |
| 25L | Large-scale industrial | Reinforced double |
Regional Market Variations
Different markets have different preferences:
- Europe: Graduated measurements in liters
- USA: Gallon measurements, pour spout essential
- Asia: Maximum capacity, metal handles standard
- Middle East: UV-resistant, light colors for heat reflection
Engineering the Perfect Bucket
Rim Design: The Foundation of Durability
The rim is the most critical part of bucket design:
Rim Cross-Section Evolution
| Generation | Design | Durability |
|---|---|---|
| Basic | Simple roll | 1 year |
| Improved | Double roll | 2 years |
| Our design | Triple roll + reinforcement | 4+ years |
Metal Handle Integration
Metal handles require specialized mould features:
Handle Insert Options
- Wire handle (4mm): Standard, cost-effective
- Tube handle (8mm): Premium feel, ergonomic
- Flat bar handle: Heavy-duty industrial
Insertion Method
- Handle lugs molded into bucket wall
- Post-moulding manual insertion
- Automatic insertion available (high-volume)
Pouring Spout Engineering
A well-designed spout improves user experience significantly:
- Spout angle: 30° for controlled pour
- Spout width: 45mm for adequate flow
- Drip edge: Prevents liquid running down bucket side
- Anti-gurgle feature: Air channel for smooth pouring
Wall Thickness Optimization
Strategic wall thickness reduces material while maintaining strength:
| Zone | Thickness | Reason |
|---|---|---|
| Base | 2.5mm | Impact resistance |
| Lower wall | 2.0mm | Hydrostatic pressure |
| Upper wall | 1.8mm | Material savings |
| Rim | 3.0mm | Handle stress |
Measurement Marking Integration
Accurate volume markings require:
- Embossed markings (permanent, no ink)
- Consistent wall thickness in marking area
- Calibration verification during mould trial
Why Choose Our Bucket Mould
Triple-roll rim design for 4+ year durability
Metal handle insert compatibility (wire/tube/flat bar)

Frequently Asked Questions
Common questions about our Bucket Mould
Can the bucket be used for food applications?
Yes, with food-grade PP or HDPE and appropriate production conditions, buckets can be FDA/EU food contact compliant. We provide material recommendations and can design for specific food safety certifications.
What is the maximum weight capacity?
Our reinforced rim design supports: 5L bucket: 8kg, 10L: 15kg, 15L: 22kg, 20L: 28kg, 25L: 35kg. Metal handle versions have 20% higher capacity.
How accurate are the measurement markings?
Embossed markings are calibrated to ±3% accuracy. We verify accuracy during mould trial and can provide calibration documentation for regulated applications.
Can custom branding be added?
Yes, we include space for logos up to 100x60mm. Options include embossed/debossed molded-in logos or flat areas for labels/printing. In-mould labeling (IML) is also possible.
What is the cycle time for different sizes?
Approximate cycle times: 5L: 20s, 10L: 28s, 15L: 35s, 20L: 42s, 25L: 50s. Actual times depend on machine specifications and cooling efficiency.
Is the bucket stackable?
Yes, buckets nest when empty (4:1 ratio approximately). Full buckets can be stacked 3-high using the interlocking rim design. We can design custom nesting features for specific logistics requirements.
