I. Core Definitions and Usage Differences
1. Turnover Box
- Definition: A reusable plastic or metal container used for temporary storage or short-distance transport of spare parts, goods, and other items.
- Typical Applications: Supermarket fresh food delivery, e-commerce sorting centers, and internal factory process flow.
- Features: Lightweight (common plastic materials weigh only 1-5 kg), foldable design (saving space), and standardized dimensions (e.g., 600 x 400 x 280 mm).
2. Material Bin
- Definition: A heavy-duty container designed specifically for industrial production lines, used to carry raw materials, semi-finished products, or finished products.
- Typical Applications: Automotive manufacturing plants (storing spare parts) and the chemical industry (holding granular raw materials).
- Features: High load-bearing capacity (up to 500 kg or more), reinforced structure (e.g., metal frame), and anti-static or anti-corrosion treatment (for special materials).
II. Material and Structure Comparison
1. Turnover Boxes
- Material: 90% are PP or HDPE plastic (impact-resistant, low-cost), with a few using metal mesh (highly breathable).
- Structure: Most are one-piece, some with removable partitions; foldable models save 60% of storage space (Data Source: "White Paper on Logistics Container Standardization").
2. Material Boxes
- Material: Steel (70%), engineering plastics (such as PA6, suitable for food-grade environments).
- Structure: Bottom rib design (improves pressure resistance), some with pulleys or forklift slots (facilitates heavy lifting).
III. Selection Recommendations: Matching Requirements to Scenario
1. Circumstances for Choosing Turnover Boxes
- Frequent handling (such as daily deliveries);
- Limited storage space (prefer foldable models);
- Lightweight cargo (single box load <50kg)
2. Material Box Selection Considerations
- Harsh environments (e.g., high temperatures, corrosive materials);
- Long-term stacking requirements (material boxes can be stacked up to five layers, while transfer boxes typically three layers);
- Compatibility with automated production lines (material boxes often meet robotic handling standards).
Additional Note: The two types of materials differ in their degree of standardization. Transfer boxes generally adhere to the national standard GB/T 5737-2015, while material box dimensions are often customized by the manufacturer based on the production line. Users should consider cost (transfer boxes cost 20-100 yuan each, while material boxes cost 200-2000 yuan each) and lifespan (plastic transfer boxes last approximately 3-5 years, while steel containers last up to 10 years) to make a comprehensive decision.
