Detailed specs for Small folding-turnover-box Wholesale from KeXinMaterials source factory. Outer/inner dimensions in mm/inch, weight, material, foam options. Compare WL2305 series. MOQ 50. 12h quote, 30-day delivery.
If you are sourcing Small folding-turnover-box Wholesale from a Chinese factory, you have probably seen marketing sheets with vague dimensions and a single IP rating. We do the opposite. Every dimension here is measured at the QC station, every rating is third-party tested.
We do not round dimensions. We do not approximate. Every line in this table is the real catalog data for Small folding-turnover-box Wholesale, measured on the production line, with QC sign-off and lot certificate. This is the data we ship with every order.
| Model | Outer (mm) | Inner (mm) | Weight (g) | Material | Size Class |
|---|---|---|---|---|---|
| WL2305 | 230×180×45 mm | 225×150×40 mm | 240 g | PP+GF | Electrician Tool Kit |
| WL2808 | 275×230×82 mm | 265×190×76 mm | 480 g | PP+GF | Plumber Tool Kit |
| WL5020 | 500×400×200 mm | 480×360×185 mm | 2400 g | PP+GF | Auto Mechanic Trolley |
The most common model for "Small folding-turnover-box Wholesale" buyers is the WL2305 (230×180×45 mm OD, 240 g empty weight, PP+GF body).
Four components define Small folding-turnover-box Wholesale protection: shell (PP or PP+GF), foam (25 kg/m³ 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 1.2m). 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 Small folding-turnover-box 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.
When evaluating Small folding-turnover-box 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 Small folding-turnover-box 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.
