Embodiment Construction

[0025] refer to figure 1 A production process embodiment of a case and bag of the present invention will be further described.

[0026] A production process for bags, comprising the steps of:

[0027] Step A. Mix the new ABS material and the secondary ABS material in proportion and put them into the mixer. After dehumidification and drying at a high temperature of 180°C to 200°C, a dry ABS mixture is obtained. The high temperature dehumidification and drying is controlled at 30 minutes to 60 minutes . ;

[0028] Step B. Put the PC material into a mixer, and after dehumidification and drying at a high temperature of 100°C to 120°C, a dry PC material is obtained, and the high temperature dehumidification drying is controlled at 30 minutes to 60 minutes. ;

[0029] Step C, the coloring material is blended, first passed through the mixer for 40 to 60 minutes, and then processed by high-temperature dehumidification and drying to obtain the blended coloring material;

[0030] S...

Abstract

The invention discloses a luggage production technique. According to the luggage production technique, mixed raw materials of acrylonitrile-butadiene- styrene (ABS) and polycarbonate (PC) are adopted, so that the injection molding difficulty in the production technique is overcome while the structural strength and the shock resistance are guaranteed; a temperature control device for a mold is added in the technological process so as to control the temperature of the circumferential wall of a forming cavity of the mold before the raw materials enter the forming cavity of the mold, so that the headmost raw materials are kept in a molten state for a period of time after entering the forming cavity of the mold, and cooling forming is conducted after all the raw materials enter the forming cavity of the mold, the situation that the thickness of luggage is not uniform due to the time difference between the raw materials firstly entering the mold and the raw materials finally entering the mold is eliminated, the consistency of the cooling time is kept, the rejection rate of luggage injection molding is decreased easily, and the production cost is better controlled.

Description

technical field [0001] The invention relates to the technical field of production technology, more specifically, it relates to a production technology of bags. Background technique [0002] As the main equipment for travel, luggage plays an extremely important role in the journey, and providing excellent protection for luggage is the first priority. Therefore, it is required not only to have accommodation, but also to have functions such as anti-extrusion, waterproof, and anti-collision. Especially the luggage should accommodate luggage, so reducing the weight of the luggage itself to the greatest extent is also what people are pursuing. [0003] With the continuous improvement of people's living standards, high-grade ABS boxes have become the main luggage materials that people like. At present, the ABS bags commonly sold on the market are mainly made of resin materials composed of three materials: acrylonitrile (A), butadiene (B) and styrene (S). And rigid material. The ...
