A strong protective case portfolio is not built around one universal size. Importers, distributors, and private-label brands need complementary formats for different equipment values, transport methods, and end-user environments. These three engineering PP cases create a practical range spanning large industrial devices, photography equipment, electronics, and portable tools.

Match the Case Format to the Equipment

For bulky or heavy equipment, the trolley hard case combines an IP67-rated enclosure, impact-resistant construction, buckle closure, foam lining, and wheeled portability. Its approximately 9,400 g structure suits applications where protection and easier ground transport are equally important. Custom foam can help organize large instruments or industrial components.

The small hard case offers a lighter format at approximately 1,120 g. It is designed for storage and transportation where water resistance, shock protection, and a fitted foam interior matter. The compact box format is particularly relevant for photography equipment, measuring devices, accessories, or service kits.

For smaller electronic equipment, the portable tool box provides IP67 waterproof, shockproof, and dustproof performance in an approximately 800 g package. Custom colors, logos, and foam inserts allow brands to create a compact case that fits both the product and its retail positioning.

Plan a More Coherent Product Line

Buyers can evaluate these models as a coordinated assortment rather than isolated products. Consider equipment dimensions, loaded weight, carrying frequency, foam layout, branding, and target price level before confirming specifications. OEM and ODM support can also align enclosure color, logo presentation, and internal organization across multiple sizes.
