PE-3U-300/W 拉杆航空箱，中深300-325㎜，实际利用空间为2U。

PE-3U-400/W 拉杆航空箱，中深400-425㎜，实际利用空间为2U。

主要升级：轮子全新模具双轮结构，更结实耐用；还有可以选择薄的盖子还是厚的盖子，这样更能减少体积。

瑞邦全新TRACK赛道系列塑料航空箱

2025年全新专利外观设计，命名为TRACK赛道系列，横条数量代表U数（例如2U就是二条），结构依旧沿用经典的铝框架，做了五处升级：
一，采用全黑色阳极氧化涂层工艺，
二，侧面为铝合金模具提手，
三，第四代蝴蝶锁扣加厚加宽喷黑，更耐用持久，
四，螺丝固定方式改为螺母分离式结构，
五，外观横条更时尚也更耐撞击。

PE Material Introduction:
PE is an internationally advanced raw material, that is, polymer polyethylene (PE for short), which is recognized as the preferred raw material for the manufacture of plastic flight boxes in the professional field. Polymer polyethylene board not only retains the high impact strength, low friction coefficient and excellent self-lubrication performance of ultra-high molecular weight polyethylene board, but also can meet the different performance needs of customers. Most of the products are green and environmentally friendly materials, which have high promotion and use value, PE sheet has the characteristics of wear and impact resistance, high temperature and low temperature resistance, high strength, good toughness, long life and light overall weight.
100% of the company's flight box products are made of PE as the main material, and we have carried out long-term cooperation with internationally renowned material suppliers.
