Raw Plastic Turnover Box sourcing is what we do before the marketing layer, the catalog layer, and the lead time layer. It is the upstream conversation. Here is what it sounds like.
For your reference, here are the WL series models we typically use for Plastic Turnover Box 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+GF | Electrician Tool Kit |
| WL2808 | 275×230×82 mm | 265×190×76 mm | 480 g | PP+GF | Plumber Tool Kit |
| WL3812 | 380×320×120 mm | 365×280×110 mm | 1100 g | PP+GF | HVAC Technician Kit |
The most common model for "Plastic Turnover Box" buyers is the WL2305 (230×180×45 mm OD, 240 g empty weight, PP+GF body).
Plastic Turnover Box shells are rated -40°C to +80°C per MIL-STD-810H Method 501.7 (high) and 502.7 (low). Chemically resistant to petroleum, mineral oil, dilute acids, alcohols, and most industrial solvents. Not resistant to concentrated sulfuric acid, aromatic, or chlorinated solvents.
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.
Common equipment we have designed Plastic Turnover Box foam layouts for, based on real customer projects since 2014: DSLR + 2-3 lenses, mirrorless kits, cinema cameras with matte box + monitor, drones (DJI Mavic/Phantom/Inspire) with 5 batteries, broadcast lighting kits, military optics, medical devices.
For Plastic Turnover Box, 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 (¥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.
Standard Plastic Turnover Box: MOQ 50 units, 30-day production, T/T 30/70. Custom: MOQ 500 units, 25-30 days mold + 30 days production. We support L/C for >$20,000 orders. Sample lead time 5-7 days, sample cost refundable on >2,000 unit order.
