We have supplied Long audio-equipment-case Wholesale to camera operators, drone pilots, broadcasters, and military contractors since 2014. This is the data sheet we send to all of them.
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 |
|---|---|---|---|---|---|
| WL3812 | 380×320×120 mm | 365×280×110 mm | 1100 g | PP+GF | Extra Large |

The most common model for "Long audio-equipment-case Wholesale" buyers is the WL3812 (380×320×120 mm OD, 1100 g empty weight, PP+GF body).
Shell material for Long audio-equipment-case Wholesale 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/m³ closed-cell PE, 0.5mm CNC cut tolerance. Anti-static ESD foam (10^6-10^11 Ω) available for electronics.
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.
Here are 3 real Long audio-equipment-case Wholesale foam layouts from 2024-2026: (A) Sony A7 IV + 24-70mm + 70-200mm + 3 filters + 2 batteries — fits WL2808. (B) DJI Mavic 3 + RC + 4 batteries + charger — fits WL2005. (C) RED Komodo + 2 lenses + monitor + cables — fits WL5020. We share these at the 12h quote stage.
When evaluating Long audio-equipment-case Wholesale options, focus on three metrics: (1) Foam density — cheap cases use 15 kg/m³ foam that bottoms out; ours is 25 kg/m³, 5+ year use. (2) Latch cycle rating — cheap plastic latches break after 200 cycles; ours is metal-reinforced, 5,000 cycles. (3) IP certification — every batch ships with serialized IP test certificates.
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 Long audio-equipment-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 use 'approximate' or 'typical' in our spec sheets. If a dimension is 250×210×70mm, that is what the QC gauge reads.

We publish both. Outer dimensions in mm (millimeters) and inches (e.g., 380×320×120mm = 14.96×12.60×4.72in). Inner dimensions follow the same dual-unit convention. Custom sizes available with MOQ 500.
WL1905, WL2005, WL2305 are all 'Medium' size (~190-230mm outer length) but differ in width and depth. WL1905 is square (190×190), WL2005 is wider (195×170), WL2305 is balanced (230×180). 0.5-1.0mm differences determine what fits — we help you choose during the 12h quote consultation.
Yes. 60+ machines, 12 production lines, 150+ custom sizes since 2014. Custom molds: 30-day lead time, MOQ 500 units, $3,000-8,000 mold fee (waived for orders >5,000 units). Send your 3D model to kexin@beeaa.com for instant feasibility check.
Standard wall thickness is 3.0-3.5mm. The 3mm walls pass IP67, the 3.5mm walls pass IP68. Wall thickness is measured at 4 points on every production batch and recorded in the lot certificate.
We use a stainless steel pin hinge (3mm diameter for small, 5mm for large) rated for 10,000 open/close cycles. Hinge caps are molded into the case body, not screwed on. The hinge pin is removable for foam service.
