Products Feature
Material: Typically made from high-impact, durable thermoplastics Polypropylene (PP). These materials offer excellent resistance to impact, moisture, chemicals, and temperature variations, ensuring a long service life.
Pin-Jointed Hinge Construction:
The side walls are connected to the base via precision pin-jointed hinges, a robust design that prevents structural failure under repeated folding cycles and heavy dynamic loads. Each hinge pin is securely retained, ensuring long-term reliability in industrial environments.
Lightweight Yet Durable:
At only 2.72kg per unit, the container is easy for operators to handle manually while still delivering industrial-grade structural performance - reducing worker fatigue without compromising durability.
Heavy-Duty Load Performance:
Each container supports a single-unit load of up to 50kg. When stacked, the reinforced base and rim structure handle a static stacking load of 150–200kg, making it suitable for multi-tier warehouse racking and high-density storage.
Reinforced Rib Structure:
A grid of raised horizontal and vertical ribs on the exterior walls and base distributes loads evenly, enhances rigidity, and prevents wall deflection or deformation when carrying dense or heavy contents such as metal fasteners and tools.
Manufacturing Process
1. Material Preparation
virgin polypropylene (pP) resin is blended with color masterbatch and uv stabilizers, then dried to ensure uniform melt quality and defect-free molding.
2. Injection Molding
The blended material is injected into precision steel molds under controlled temperature and pressure, forming the container base, folding side walls, and snap-lock components. Controlled cooling ensures dimensional accuracy within ±5mm.
3. Assembly
Side walls are attached to the base via solid pin-jointed hinges. The snap-lock mechanism is installed and calibrated for firm locking and smooth release - no tools required for end-user operation.
4. Quality Control
Each batch passes dimensional checks, fold-unfold cycle tests, 50kg single-load and 150–200kg stacking-load verification, and visual inspection for surface defects.
5. Packaging
Approved units are folded to 78mm, stacked on pallets, shrink-wrapped, and labeled with batch and specification details before warehousing.

FAQ
Q: Howmuch storage space does the folded container save?
A: When folded, the height drops from 280mm to just 78mm - a 72% reduction. This means you can store or ship roughly 3.6 times more empty containers in the same floor space compared with rigid, non-folding bins of the same size.
Q: What is the pin-jointed hinge design and why is it important?
A: Pin-jointed hinges use solid retaining pins to connect the folding side walls to the container base. Unlike snap-in or living-hinge designs, pin joints resist fatigue from thousands of fold-unfold cycles and prevent the side panels from detaching, ensuring a longer service life in demanding industrial settings.
Q: What are the exact internal dimensions and usable volume?
A: The internal dimensions are 570×370×270mm (±5mm), providing a usable volume of 57 liters. The slightly tapered interior allows for smooth part insertion and easy cleaning, while the flat base maximizes contact area for small components.
Q: How should I clean and maintain these containers?
A: The smooth polypropylene surface can be cleaned with warm water and mild detergent, or wiped with standard industrial disinfectants. Avoid abrasive brushes that may scratch the surface. The snap-lock and pin-joint mechanisms require no lubrication; simply ensure they are free of debris for smooth operation.
Q: Are lids, dollies, or label holders available for this model?
A: Yes. Matching plastic lids, label card holders, and compatible dollies can be ordered separately. Custom color matching and logo printing are also available for bulk orders. Please contact our sales team for accessory pricing and minimum order quantities.
