The long-tail of Waterproof ore-sampling-case Wholesale sourcing is where the real value is. Head terms are dominated by catalogs and trading companies. This page is built for buyers who know exactly what they need.
For your reference, here are the WL series models we typically use for Waterproof ore-sampling-case Wholesale 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 |
|---|---|---|---|---|---|
| WL2305 | 230×180×45 mm | 225×150×40 mm | 240 g | PP | Multimeter / Caliper |
| WL2808 | 275×230×82 mm | 265×190×76 mm | 480 g | PP+AS | Surveying Total Station |
| WL5020 | 500×400×200 mm | 480×360×185 mm | 2400 g | PP+AS | Optical Microscope |
The most common model for "Waterproof ore-sampling-case Wholesale" buyers is the WL2305 (230×180×45 mm OD, 240 g empty weight, PP body).
Cheap protective cases use 15 kg/m³ foam that bottoms out after 6 months. Our Waterproof ore-sampling-case Wholesale uses 25 kg/m³ foam rated for 5+ year use. The difference is in the cell structure: 25 kg/m³ cells rebound after compression, 15 kg/m³ cells do not. We have tested both. The cheaper foam fails.
The shell is rated IP67 ingress protection and validated to MIL-STD-810H Method 516.8 (26 drops at 1.2m). Temperature range is -40 ~ +80 °C. 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.
In 2024, we shipped Waterproof ore-sampling-case Wholesale for: (1) Film production — ARRI Alexa Mini + accessories in custom foam. (2) Drone operators — DJI Mavic 3 + RC + 6 batteries. (3) Broadcast — RED Komodo + 2 lenses + monitor. (4) Military — rifles + scopes + ammo. (5) Medical — first aid kits + AED.
Cheap Waterproof ore-sampling-case Wholesale: $3-8/unit, 6-month lifespan, 200-cycle latch, 15 kg/m³ foam. Our Waterproof ore-sampling-case Wholesale: $5-15/unit, 10-year lifespan, 5,000-cycle latch, 25 kg/m³ foam. Over 5 years, our case is 4-5x cheaper per year of use. Total cost of ownership wins.
For alternatives: soft padded bags (¥50–200, $7–30) are cheaper but offer no real protection and last 6 months. Aluminum hard cases ($80–300) are heavier, prone to denting, and 2–4× 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.
Ordering Waterproof ore-sampling-case Wholesale is 5 steps: inquiry (12h response), quote (with recommendation), PO + 30% deposit, production (30 days + QC photos), balance payment + shipment. Repeat orders are 15-20 days. Custom OEM/ODM adds 25-30 days for mold.
We do not charge extra for long-tail specs. Standard WL series pricing applies unless the spec requires a new mold.

Yes. Silver-ion anti-microbial additive in the PP compound, effective against 99.9% of bacteria per ISO 22196. Common in medical cases. Adds $1.50-3 per unit depending on size. Lead time +5 days.
UV-resistant: UV-stabilized PP compound, ASTM G154 500-hour tested, ΔE < 2.0 after exposure. Fire-retardant: UL94 V-0 rated material, no toxic flame retardants. Both add $1-3 per unit, 5-day additional lead time.
Standard: 3.0-3.5mm. Thinnest: 2.0mm (with reduced drop rating). Thickest: 5.0mm (with reinforced ribbing). Wall thickness <2.0mm requires special tooling. We optimize wall thickness per use case during the DFM review.
Standard foam: 3-axis CNC, 0.5mm tolerance, ±0.2mm cut precision. 5-axis foam: 0.3mm tolerance, for complex cavities (lenses, irregular shapes, multiple small items). Adds 3-5 days lead time, $5-15 per foam set premium.
Stock modifications: 15-20 days. New mold: 25-30 days after design approval, plus 5-7 days for sample. Full process: 30-40 days from spec confirmation to first production batch. We expedite (10-15 days) for orders >5,000 units with surcharge.
