WL1-5419 Protective Case

Both versions share the same dimensions, wall thickness and structure, and differ in material and weight: the PP version weighs about 3110 g and the ABS version about 3600 g. The PP version is lighter, which suits frequent handling or projects billed by total carton weight, while the ABS version is heavier and is often preferred where surface finish and rigidity matter for appearance. Judge by loaded weight, handling method and appearance requirements together, for example ABS for medical equipment cases where feel and finish count, and PP where weight saving and freight cost lead. Confirm material availability with the Zhongshan plant.

With a 540 x 445 x 190 mm outer, a 525 x 400 x 170 mm cavity and 85 mm lid and base depth, this is a large specification in the 1 Series, suited to larger instruments, benchtop test equipment, medical devices and complete instrument sets. Note that the export data does not record a narrowest clearance for this model, so opening clearance cannot be judged from that figure. Size from the 525 x 400 x 170 mm inner dimension and reserve foam thickness above and below. For devices with handles, connectors or multiple layers, send the assembled outline and weight to Kexin New Materials (Guangdong) Co., Ltd. in Zhongshan for a clearance and insert review.

The export data records one poly bag per piece and a carton of 550 x 485 x 755 mm holding a single piece. One piece per carton means a relatively large volume per unit, so container loading, pallet stacking and warehouse height all need planning, and freight behaves more like volume-based charging. For bulk orders, give the factory the target quantity, destination port or delivery point, and whether palletising or a stacking limit applies, so volume and weight figures are quoted against the actual packaging plan rather than estimated from loose units.

At 5 mm the wall is a thicker specification in the 1 Series, and with PP or ABS the body keeps margin against compression and deformation, which suits heavier items such as larger instruments and medical equipment during storage and transport. The case is built in an IP67 waterproof and dustproof direction, limiting dust and liquid ingress for field and workshop use. Be aware that the data provides no water test report and JUNZHIJIA makes no MIL-STD or comparable military certification claim, so where a project sets acceptance criteria for water resistance, load or stacking, agree the method with the factory in advance.
