How to choose a good aluminum frame trolley box

As a necessity for our travels, trolley cases are undoubtedly irreplaceable. The aluminum frame trolley box is now the first choice for travel. However, some people like to compare the aluminum frame trolley case and the zipper box when buying. But for the same bags, the construction of the zipper box and the aluminum frame trolley case is not a difference in quality, but a choice based on people's travel habits. Here I want to introduce to you the deep-frame trolley box that can really be compared with the aluminum frame trolley box, but the deep-frame trolley box occupies less than 5% of the world's luggage market.

Deep frame, that is, deep aluminum frame, different from ordinary aluminum frame, then, where is his advantage?

First of all, we can compare from the material and find that the ordinary aluminum frame trolley box is made of 370G/M ordinary aluminum, because the ordinary aluminum frame structure is simple, the shape is flat, there is no undulating structure, ordinary aluminum, the amount of aluminum is moderate. The structure is simple and easy to process, so the production cost is moderate and higher than the zipper box, the production process is mature, and the quality cost is higher than the zipper box, which is a good travel choice. And in terms of sales, aluminum frame trolley boxes account for more than 90% of the market.

In contrast, because the ordinary aluminum frame process is simple and the cost is low, 90% of the aluminum frame suitcases on the market are produced with this structure. While following the flow, the structure and process that are too streamlined are prone to deformation after being violently impacted, resulting in poor opening and closing, and not tight closing. This also creates the defects of ordinary aluminum frame trolley boxes.

The material of the deep aluminum frame is better than the ordinary one, using 450G / M ordinary aluminum, and because the deep frame structure is complex, the shape is undulating and bending, so the amount of aluminum is very large, whether it is the material cost or the production cost is much higher than the ordinary flat frame, because the structural requirements need to be integrated molding, the machine process has good requirements, so only a few large factories in China can complete the production. The complex production process is destined to have low output and high cost, which is the first choice for high-quality consumer travel. However, its market share is only about 4%.

In addition to the deep aluminum frame trolley box is also supported by aluminum alloy in the middle, the aluminum double U-shaped lock structure of the deep frame makes the upper and lower covers of the aluminum frame tightly blocked and not easy to shake and not leak gaps. The density and compression resistance of deep frames are much higher than ordinary aluminum frames, and the aluminum content is higher.

From the above materials, I think we should have a general outline of the selection of aluminum frame trolley cases. In addition to special circumstances, the quality of ordinary aluminum frame trolley boxes is enough to meet our needs for trolley boxes.
