If you have been burned by a stream-tracing-bag certification process supplier before — wrong dimensions, fake IP rating, lead time that doubled mid-order — this page is for you. It is the buyer's guide we wish someone had given us in 2014.
Below is the catalog data for stream-tracing-bag certification process. Each model has outer dimensions (in mm), inner cavity (mm), empty weight (g), and material specification. Material is engineering PP or PP+GF for impact resistance. Foam set is included: 25mm base + 10mm lid convoluted.
| Model | Outer (mm) | Inner (mm) | Weight (g) | Material | Size Class |
|---|---|---|---|---|---|
| WL1204 | 120×90×40 mm | 115×78×32 mm | 100 g | PP | Phone / Wallet |

The most common model for "stream-tracing-bag certification process" buyers is the WL1204 (120×90×40 mm OD, 100 g empty weight, PP body).
All stream-tracing-bag certification process cases use engineering-grade polypropylene (PP) or PP+glass-fiber composite (PP+GF) for the shell, with CNC-cut closed-cell PE foam inside (density 25 kg/m³). The foam density is calibrated to absorb 1.2m drops on concrete while keeping your equipment from shifting.
The shell is rated IP68 (submersible 5m / 30 min) ingress protection and validated to MIL-STD-810H Method 516.8 (26 drops at 2.0m). Temperature range is -30 ~ +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.
We maintain 200+ foam-cut reference designs for stream-tracing-bag certification process, covering camera bodies, drone kits, broadcast gear, military equipment, medical devices, and industrial tools. Send us your equipment list, we will match to the closest reference or draft a new layout free within 24 hours.
When evaluating stream-tracing-bag certification process 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.
Standard stream-tracing-bag certification process: MOQ 100 units, 25-day production, T/T 30/70. Custom: MOQ 500 units, 25-30 days mold + 25 days production. We support L/C for >$20,000 orders. Sample lead time 5-7 days, sample cost refundable on >2,000 unit order.

We use injection molding exclusively — denser walls, tighter tolerances, better IP rating. Blow molding produces hollow cases with thinner walls (1-2mm), cheaper, but not suitable for IP67 or MIL-STD-810H drop test. If a supplier offers 'injection' at 1/3 our price, it is likely blow-molded.
Yes for DDP and CIF. For FOB or EXW, we ship to a commercial port or address with customs broker. Residential delivery in some regions (EU, USA) requires a local broker to handle customs clearance.
stream-tracing-bag certification process refers to a protective case designed for specific equipment, use case, and buyer profile. In B2B sourcing, it means a factory-direct product with documented specs, certifications, and lead time. KeXinMaterials has supplied stream-tracing-bag certification process to 47 countries since 2014.
Step 1: Define your equipment's outer dimensions (L×W×H in mm). Step 2: Add 5-10mm clearance for foam thickness. Step 3: Match to WL series: WL1204 → WL2005 → WL2808 → WL3812 → WL5020. Step 4: Confirm IP rating (IP65 indoor, IP67/IP68 outdoor/water). Step 5: Send spec for 12h quote.
Top 5 mistakes: (1) Choosing by price alone, ignoring that cheap cases skip IP certification. (2) Over-specifying size — buying WL5020 when WL3812 fits. (3) Ignoring latch type — 200-cycle vs 5,000-cycle. (4) Forgetting pressure valve for air travel. (5) Not requesting lot certificates.
