Sourcing PP Case / Polypropylene Box In Stock at the right price means understanding the cost stack: resin, mold amortization, foam, labor, packaging, and shipping. We break it all down below โ the same breakdown we use internally.
If you have not worked with the WL series before, this is the cheat sheet. WL1204-WL1504 are Small (under 200mm). WL1905-WL2808 are Medium (200-300mm). WL3812-WL5020 are Large (300-500mm). Within each tier, the model number encodes the length, width, height in cm.
| 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 |
| WL3812 | 380ร320ร120 mm | 365ร280ร110 mm | 1100 g | PC+GF | Industrial Kit |
The most common model for "PP Case / Polypropylene Box In Stock" buyers is the WL1204 (120ร90ร40 mm OD, 100 g empty weight, PP body).
Four components define PP Case / Polypropylene Box In Stock protection: shell (PP or PP+GF), foam (25 kg/mยณ closed-cell PE), seal (silicone gasket around the lid), and pressure valve (automatic Gore-Tex membrane for IP67/IP68). Each component is tested. Each can be replaced if worn.
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 In Stock 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.
For PP Case / Polypropylene Box In Stock, the decision comes down to: equipment dimensions (always measure with 5-10mm foam clearance), IP rating (IP65 indoor, IP67 outdoor, IP68 water), and certification (FCC for USA, CE for EU, MIL-STD for military). Beyond that, it is foam layout and quantity discount.
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.
