Problems solved by technology

EVA material is flexible, but not rigid enough. In the process of making luggage, skeleton support is needed, which increases the production process, and EVA material has a special smell, which affects the health of users; It has limitations, and it is easily broken when it receives a tensile impact greater than its tensile impact; PC engineering plastics have poor fluidity and the injection molding process is difficult
Foaming material is also an option for lightweight luggage shells, but foaming materials are expensive, poor in shaping strength, and their applications are limited

Embodiment Construction

[0015] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0016] The following reference figure 1 and figure 2 The present invention will be described.

[0017] A method for preparing a case shell, comprising the steps of:

[0018] (1) A plastic plate 1 with a thickness of 5-9mm is selected as the skeleton, and a cloth 2 with a melting point higher than 200°C is selected as the outer layer; the melting point of the cloth is higher than 200°C to prevent the cloth from being damaged during the hot pressing process.

[0019] (2) Lay the plastic plate 1 and the fabric 2 together and heat-compress and compound them through a hot-press laminating machine to obtain a composite plate. The thickness tolerance of the composite plate is...

Abstract

The invention discloses a preparation method of a luggage shell. A plastic plate with the thickness of 5-9 mm is selected as a framework, cloth with the melting point higher than 200 DEG C is selected as an outer layer, the plastic plate and the outer layer are hot-pressed and compounded through a hot-pressing compounding machine to obtain a compound plate, the luggage shell is processed and formed through a forming die, the manufacturing process of the luggage shell is improved and optimized through control over temperature, time and other parameters, and the luggage shell which is good in forming quality and rigidity, light, environmentally friendly and good in impact resistance is obtained.

Description

technical field [0001] The invention relates to the field of bags, in particular to a method for preparing a case shell. Background technique [0002] Luggage is an essential daily necessities for people, and people are constantly developing and experimenting with various materials to make luggage. Lightweight luggage is the focus of the current new luggage reform. Lightweight bags can make people travel more convenient and comfortable, can improve people's lives, reduce the fatigue of the journey, can easily carry more items, and increase the convenience of the journey. However, there are not many materials that can really be used to make lightweight luggage shells. People usually choose materials with better thermoplasticity to make bags. Plastic is a material with higher strength and good formability, such as EVA, ABS, PC and so on. EVA material is flexible, but not rigid enough. In the process of making luggage, skeleton support is needed, which increases the producti...
