What material is good for mounting the chassis?

What are the common materials for mounting the chassis?
1、ABS
ABS is a popular fashion material for trolley cases recently, characterized by its lightness, flexibility, rigidity, and impact resistance compared to other materials. The ABS box can better protect the items inside. Although it feels soft and not sturdy to the touch, it is actually very flexible, and most adults have no problem standing on it. Cleaning is also relatively convenient, but the disadvantage is that it is prone to scratches, but the previous box cover will be much better.
2. Oxford cloth
This is a type similar to nylon, with the advantages of being wear-resistant and practical. The disadvantage is that the material of this trolley case is uniform, making it difficult to distinguish luggage at the airport, and it is relatively heavy. But there is no need to worry about the harm it may cause to the box when it is shipped, and it is still the same after a few years of use.
3. PU skin
As the name suggests, this type of box is made of artificial leather PU material. The advantage of this type of box is that it is very similar to cowhide, appears high-end, and is not afraid of water like a leather box. The disadvantage is that it is not wear-resistant and not very sturdy, but the price is low.
4. Canvas
This type of suitcase material is not very common, but in terms of canvas, the biggest advantage is that it is wear-resistant like Oxford cloth, while the disadvantage is that its impact resistance is not as good as Oxford cloth. The canvas material is evenly colored, and some surfaces may be brighter and look good. However, over time, there will be a unique sense of vicissitudes.
5、pvc
That is to say, the hard box, like a tough guy, is resistant to falling, waterproof, impact resistant, wear-resistant, fashionable, and can be said to be much stronger than ABS, making it the strongest box in the world. The surface is smooth and good-looking, without worrying about scratches due to rough handling. The biggest drawback is that it is heavy and can easily weigh around 20 kilograms. It should be noted that many airlines limit it to 20 kilograms, which means that the box weight accounts for half.
6. Cowhide
Generally speaking, the material of the cowhide pull rod box is the most expensive, and it is also relatively expensive. It is afraid of water, abrasion, pressure, and scratches. However, as long as it is properly kept, the box is very valuable.
