When the design of the luggage is completed, it will enter the process of making the mold. The cost of making the mold is also different according to the material needed in the design of the luggage. For example, the fabric luggage is made with a cardboard mold, which is mainly used for cutting fabric. The plastic luggage needs to make a plastic mold, but the plastic mold is divided into injection mold and vacuum forming mold. Taking PP luggage for example, we need to make the injection mold, the cost is very expensive, usually to more than 10W yuan. But for PC, ABS, ABS+PC and other materials, we only need to make vacuum forming molds, that is generally made of aluminum, its cost is between 2000 and 10000 yuan. Besides, the cost of making the mold is usually determined by the size of the luggage. The bigger, the more fee. At present, the mainstream market of luggage is mainly produced by vacuum forming molds, the reason is that the cost is low, there are many styles and colors.
