For your reference, here are the WL series models we typically use for PP Case / Polypropylene Box Factory applications. Outer dimensions (OD) are measured to the outside of the case; inner dimensions (ID) reflect the usable cavity after subtracting wall thickness. All in millimeters; imperial dimensions in our catalog PDF.
| Model | Outer (mm) | Inner (mm) | Weight (g) | Material | Size Class |
|---|---|---|---|---|---|
| WL1204 | 120ร90ร40 mm | 115ร78ร32 mm | 100 g | PP | Component Storage |
| WL2005 | 195ร170ร46 mm | 190ร135ร40 mm | 175 g | ABS | Tool Kit |
| WL8040 | 800ร500ร400 mm | 770ร470ร370 mm | 7800 g | PP+GF+UV | Heavy Industrial |
The most common model for "PP Case / Polypropylene Box Factory" buyers is the WL1204 (120ร90ร40 mm OD, 100 g empty weight, PP body).
Shell material for PP Case / Polypropylene Box Factory is selected per use case: standard PP for general purpose, PP+GF for heavy-duty (10% glass fiber improves impact strength by 35%). Foam is 25 kg/mยณ closed-cell PE, 0.5mm CNC cut tolerance. Anti-static ESD foam (10^6-10^11 ฮฉ) available for electronics.
The shell is rated IP65 ingress protection and validated to MIL-STD-810H Method 516.8 (26 drops at 1.5m). Temperature range is -30 ~ +90 ยฐC. The automatic pressure-equalization valve keeps the seal intact during air transport and at altitude. Latch is a double-throw design rated for 5,000 open/close cycles. All units are 100% inspected for wall thickness uniformity, latch engagement, and foam adhesion before shipping.
Here are 3 real PP Case / Polypropylene Box Factory foam layouts from 2024-2026: (A) Sony A7 IV + 24-70mm + 70-200mm + 3 filters + 2 batteries โ fits WL2808. (B) DJI Mavic 3 + RC + 4 batteries + charger โ fits WL2005. (C) RED Komodo + 2 lenses + monitor + cables โ fits WL5020. We share these at the 12h quote stage.
When evaluating PP Case / Polypropylene Box Factory options, focus on three metrics: (1) Foam density โ cheap cases use 15 kg/mยณ foam that bottoms out; ours is 25 kg/mยณ, 5+ year use. (2) Latch cycle rating โ cheap plastic latches break after 200 cycles; ours is metal-reinforced, 5,000 cycles. (3) IP certification โ every batch ships with serialized IP test certificates.
For alternatives: soft padded bags (ยฅ50โ200, $7โ30) are cheaper but offer no real protection and last 6 months. Aluminum hard cases ($80โ300) are heavier, prone to denting, and 2โ4ร the price. Carbon fiber cases ($300+) are overkill for 95% of B2B use cases. Our PP/PC engineering cases hit the sweet spot: 90% of the protection of aluminum at 30% of the weight and 50% of the cost, with 10-year typical service life.
