High-Quality Storage Box Molds – Engineered for Efficiency & Durability
In the world of daily-use plastics, storage boxes and containers are among the most produced items globally. From kitchen organizers and wardrobe bins to industrial stacking totes, the demand for durable, stackable, and aesthetically pleasing storage solutions continues to grow.
Behind every successful storage box product lies a precision-engineered injection mold. At NEW STAR MOULD, we specialize in designing and manufacturing high-cavity, long-life molds for storage boxes of all sizes and applications.
Why Storage Box Molds Require Special Attention
Unlike simple plastic parts, storage boxes come with unique molding challenges:
| Challenge | Our Solution |
|---|---|
| Warpage on large flat lids | Optimized gate location and cooling channel design |
| Uniform wall thickness | Advanced mold flow analysis before steel cutting |
| Stacking ribs & undercuts | Precision slide and lifter mechanisms |
| High-volume production | Hardened steel (H13/S136) and multi-cavity layouts |
| Clear or tinted aesthetic | High-polish cavity surface for optical clarity |
Our Capabilities for Storage Box Molds
At NEW STAR MOULD, we offer end-to-end solutions for storage box projects:
1. Mold Types We Manufacture
Stackable storage box molds (with lid)
Under-bed storage container molds
Modular drawer organizer molds
Industrial stacking tote molds
Food storage container molds (airtight with sealing lids)
2. Cavity Options
Single cavity – for large boxes (e.g., 50L+ storage bins)
Multi-cavity – for small organizers (2, 4, 8 cavities per mold)
Family molds – produce box + lid in the same cycle
3. Steel & Surface Finish
| Component | Recommended Steel | Surface Finish |
|---|---|---|
| Cavity & Core | S136, 2316, H13 | High polish (SPI-A2) or fine texture |
| Slides & Lifters | 718H, P20+H | Wear-resistant coating optional |
| Base & Clamping Plate | 50C, P20 | Standard machined finish |
4. Key Features We Integrate
Hot runner systems (YUDO, HASCO, or customer-specified)
Automatic unscrewing for threaded lids
Air ejection for deep-drawn boxes
Quick mold change interface for high-volume production lines
Case Example: 4-Cavity Stackable Storage Box Mold
Project: 8L stackable storage box with transparent lid
Material: PP (box) + PS (lid)
Cavity: 4+4 (4 boxes + 4 lids in one mold)
Steel: S136 for cavity, 718H for core
Cycle time: 35 seconds
Mold lifetime: 1.5 million shots
Result: The customer achieved 30% faster production compared to their previous supplier, with zero warpage issues on the lid.
Quality Assurance at Every Stage
We don't just deliver a mold — we deliver confidence. Our quality control includes:
Incoming material inspection – steel hardness & composition check
In-process inspection – electrode, cavity, and core dimensions
CMM measurement – full geometric report before assembly
Mold trial – sample parts with full dimensional report
Final inspection – water channel pressure test, heater check, accessory confirmation
