1.Look at the gap
A good American aluminum alloy trolley box is made of a whole piece of aluminum magnesium alloy material and is die-cast as a whole. The connection part at the back of the box will not have any gaps, and the waterproof effect is very good. At present, many trolley cases on the market are made of two piece or loose piece aluminum magnesium alloy splicing, and the back gap is covered by other materials. When purchasing American aluminum alloy trolley cases, it is important to pay attention to whether the gaps in the box are covered.
2.Look at the pull rod
The pull rod part of the magnesium aluminum alloy suitcase is also made of American aluminum material, which is very smooth and has a good visual and silent effect. Generally, there is no sound when pulling up or pushing back, and this effect can be maintained for a long time. Some trolley cases start to pull out and push back very well, but over time, this effect is difficult to maintain, making it more difficult to push back and pull out.
3.Handheld handle
The design of the hand handle is a particular aspect of the trolley case. When the hand handle of a low-end trolley case is lifted, it will automatically retract and the sound will be emitted by the collision box. This is because traditional trolley case handles are forcibly pulled back by springs, and over time, the spring will deform and lose its rebound effect. The handle design of aluminum alloy trolley cases generally adopts a damping rebound design, which is silent in rebound. When choosing, you can try the rebound feel of the handle a few more times.
4.Box surface
The color of the American aluminum alloy trolley luggage is generally silver gray, with other colors such as gold, blue, and pink. The coloring of the surface of the box is a technical activity. Currently, there are two mainstream coloring techniques: spray painting and oxidation. The painted boxes start to come in beautiful colors, but it won’t take long for the paint to peel off. The oxidation technology has a relatively long-lasting coloring and strong resistance to fading, with almost no fading. When buying a box, pay attention to checking the surface of the box. If there are small particles visible to the naked eye on the surface of the box, it is usually sprayed with paint. Due to uneven spraying or high dust in the spraying environment, there are small particles on the surface. Oxidized boxes are easier to identify, with a flat surface and no visible small particles, and a smooth feel.
5.Wheels
The wheels of a typical trolley box are prone to bumps and loud noise during towing. Alloy trolley cases are generally designed with two wheels, which are relatively stable and have good cushioning effect during towing.
6.Trolley case password lock
The design of a typical trolley case password lock is very simple, and the lock is easily broken, making it generally unusable when traveling abroad. Aluminum magnesium alloy trolley cases are generally designed with TSA customs locks. If luggage carried during overseas travel is inspected by customs, customs will use special tools to open your suitcase. If TSA customs locks are not installed, unfortunately, they will directly force open your suitcase.
