Component Specifications

Definition
The primary structural component of high-density polyethylene storage containers that forms the main enclosure for storing materials. It is typically manufactured through rotational molding or blow molding processes to create a seamless, durable body with uniform wall thickness. The container body includes integrated features such as stacking ribs, lifting lugs, and reinforcement structures to withstand mechanical loads and environmental stresses during industrial storage and handling operations.
Working Principle
The container body functions as a pressure vessel and structural shell that contains stored materials while resisting internal and external forces. It distributes mechanical loads through its geometric design and material properties, utilizing HDPE's high strength-to-density ratio and chemical resistance to maintain integrity under various storage conditions. The seamless construction prevents leakage paths, while integrated reinforcement features enhance load-bearing capacity during stacking and transportation.
Materials
High-Density Polyethylene (HDPE) with density range 0.941-0.965 g/cm³, melt flow index 0.1-0.5 g/10min, UV stabilizers (2-3% carbon black or HALS additives), antioxidant packages (0.1-0.3% phenolic/phosphite blends)
Technical Parameters
  • Surface Finish Ra 3.2-6.3 μm
  • Wall Thickness 4-12 mm
  • Impact Strength ≥50 kJ/m² at 23°C
  • Chemical Resistance Resistant to acids, alkalis, salts up to pH 2-12
  • Dimensional Tolerance ±1.5% of nominal dimension
  • Maximum Stacking Load 1500 kg
  • Operating Temperature -40°C to +60°C
Standards
ISO 9001:2015, ISO 14001:2015, DIN 8078, DIN 16901, FDA 21 CFR 177.1520

Frequently Asked Questions

What manufacturing processes are used for HDPE container bodies?

Primary manufacturing methods include rotational molding for seamless construction and uniform wall thickness, and blow molding for high-volume production. Rotational molding is preferred for complex geometries and integrated features, while blow molding offers faster cycle times for standard designs.

How does wall thickness affect container performance?

Wall thickness directly impacts structural integrity, impact resistance, and chemical permeation. Thicker walls (8-12mm) provide better stacking strength and longer service life, while thinner walls (4-6mm) reduce material cost and weight for light-duty applications.

What maintenance is required for HDPE container bodies?

Regular inspection for cracks, stress whitening, and UV degradation; cleaning with mild detergents; avoiding exposure to temperatures above 60°C; and proper stacking within rated capacity limits. No special coatings or treatments are typically required.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
