Hejun Haoyun Plastic Products Factory, located in Hejian City, Hebei Province, has established itself as a leading manufacturer specializing in injection-molded plastic buckets for diverse industrial applications. With a 5,000-square-meter production facility equipped with state-of-the-art machinery and automated production lines, the company delivers high-quality packaging solutions that meet global standards.
Core Product Range & Technical Specifications
The company’s comprehensive product portfolio addresses the specific needs of multiple industries through specialized container designs:
- Biological Agent Packaging Buckets: Engineered with food-grade materials and enhanced UV resistance, these containers maintain microbial viability during storage and transportation. Available in 10L-25L capacities with tamper-evident lids.
- Pesticide Special Plastic Buckets: Constructed from HDPE with chemical resistance certification, these containers feature double-wall construction for added safety. Standard sizes include 5L, 10L, and 20L options with child-resistant caps.
- Car Wash Liquid Packaging Buckets: Designed with ergonomic handles and precision pour spouts, these containers range from 5L to 15L capacities. Special anti-static treatment prevents liquid adhesion during dispensing.
- Agricultural Fertilizer Buckets: Built with reinforced rims and stackable designs, these heavy-duty containers withstand rough handling in farm environments. Available in 15L-25L sizes with optional measurement markings.
- Fireproof Coating Buckets: Featuring flame-retardant additives and thermal insulation layers, these specialized containers maintain coating properties at elevated temperatures. Standard 20L capacity with airtight seals.
All products undergo rigorous testing including drop tests from 1.2 meters, leak tests under 0.5 bar pressure, and UV aging simulations exceeding 500 hours. The production facility maintains ISO 9001 quality management certification with daily batch sampling and third-party inspection protocols.
Advanced Manufacturing Capabilities
The company’s competitive edge stems from its vertically integrated production system combining precision mold making with automated injection molding:
The 12-station automated production line achieves consistent output of 15,000 units daily with defect rates below 0.3%. Key manufacturing advantages include:
- Material Precision: Computer-controlled material feeding ensures exact resin ratios for optimal container properties
- Mold Technology: CNC-machined molds with mirror polishing achieve surface finishes below Ra 0.8μm
- Process Control: Real-time monitoring of injection pressure (800-1200bar), temperature (220-260°C), and cooling time (15-20s)
- Decoration Options: In-mold labeling achieves 360° branding with 0.1mm registration accuracy; heat transfer printing enables complex graphics
The facility’s environmental management system recycles 98% of production waste through closed-loop material recovery systems. Energy-efficient servo motors reduce power consumption by 35% compared to traditional hydraulic systems.

Customization & Engineering Solutions
The company’s engineering team provides comprehensive customization services through three development stages:
- Concept Design: 3D CAD modeling with flow simulation to optimize container geometry for specific contents
- Prototype Development: Rapid tooling production (7-10 days) with iterative testing for functional validation
- Mass Production: Mold modification capability to adjust wall thickness, rib patterns, and handle positions
Recent custom projects include:
- Anti-static containers for electronic chemical packaging with surface resistance <10⁹Ω
- UN-certified hazardous material containers meeting DOT-SP 10929 specifications
- Stackable containers with interlocking bases for automated warehouse systems
- Temperature-controlled buckets with phase change material (PCM) inserts for cold chain logistics
The company maintains a library of over 200 existing molds enabling cost-effective production for common specifications. Custom mold costs can be amortized across minimum order quantities as low as 5,000 units for standard designs.
FAQ
What are the minimum order quantities for custom plastic buckets?
Our standard molds support MOQs starting from 3,000 units for basic designs, while fully custom molds require minimum orders of 5,000-10,000 units depending on container complexity. We offer flexible production batches with staged deliveries to help manage inventory costs.
How do you ensure chemical compatibility for specialized containers?
All material selections undergo comprehensive compatibility testing following ASTM D543 standards. We maintain a database of over 200 chemical formulations with recommended resin types. For new applications, we provide free sample testing with 72-hour immersion analysis.
What certifications do your industrial containers hold?
Our products comply with multiple international standards including FDA food contact compliance (21 CFR 175.300), EU REACH regulations, and UN recommendations for the transport of dangerous goods. Specific certifications vary by product type and can be provided upon request.
How does your production process ensure consistent quality?
We implement a five-layer quality control system: 1) Raw material inspection with FTIR spectroscopy 2) In-line process monitoring with statistical process control 3) Automated vision inspection for surface defects 4) Random sampling for physical property testing 5) Final batch audit before shipping.
What lead times should be expected for bulk orders?
Standard products from inventory ship within 7-10 days. For made-to-order containers, production lead times are 25-35 days depending on order volume and customization requirements. We maintain safety stock of popular sizes to expedite delivery for repeat customers.
