The Three Questions Extra Large trolley-case Manufacturer Buyers Ask First

Extra Large trolley-case Manufacturer buyers usually start with two questions: what fits, and how much does it weigh empty. Then comes the third: is the case actually IP67, or is that printed on the box? We answer all three with data.

Extra Large trolley-case Manufacturer Catalog: Outer, Inner, Weight, Material

Below is the catalog data for Extra Large trolley-case Manufacturer. 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.

The most common model for "Extra Large trolley-case Manufacturer" buyers is the WL3812-T (380×320×120 mm OD, 1400 g empty weight, PP+Aluminum Frame body).

Why Foam Density Matters for Extra Large trolley-case Manufacturer

Cheap protective cases use 15 kg/m³ foam that bottoms out after 6 months. Our Extra Large trolley-case Manufacturer 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 IP54 (splash-resistant, not submersible) 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.

Extra Large trolley-case Manufacturer vs Alternatives: Honest Comparison

When evaluating Extra Large trolley-case Manufacturer 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.

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.

What's the difference between WL models in the same size range?

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.
