Mobile phone holsters are an emerging product that has only emerged in recent years. The more official explanation is this: a mobile phone protective cover, a jacket designed and produced to protect the mobile phone. In the mid-to-late 1990s, mobile phone protective sleeves became popular due to the opportunity of slimming mobile phones. They also protected mobile phones for aesthetic purposes. Their types also became diversified with the increase of mobile phone brands and functions. They are divided by texture. There are leather, silicone, cloth, hard plastic, soft plastic, velvet and silk, etc. According to the model, there is a difference between a straight plate and a flip cover. Depending on the model, the applicable categories of mobile phone case
s are also different. The candy bar can usually use all types of mobile phone cases, while the sliding type folding type can only choose leather cases. Compared with the mobile phone protective cover, the mobile phone holster is a mobile phone protective cover made of imitation leather or genuine leather. With the popularization of smart phones and consumers' demand for mobile phone protection performance, mobile phone holsters have now become a common equipment for smart phones, so how is a mobile phone holster made? 1 Regarding the selection of raw materials when producing mobile phone leather cases. To make a beautiful and fashionable mobile phone leather case, we need to choose various high-quality raw materials, and then process them into a complete mobile phone leather case. Which raw materials will be used? Below we conduct a detailed analysis: a: Fabric part: The main fabric material can be leather and imitation leather. b: Mid-board: Hard paper shell, pvc board or microfiber board can be used. c: Lining part: mainly use microfiber pu leather or pvc frosted leather or imitating microfiber three kinds of materials. d: Adhesive material: mainly hot melt glue or glue for pasting. d-1: Hot melt adhesive is a kind of plastic adhesive. Its physical state changes with temperature within a certain temperature range, while its chemical properties remain unchanged. It is non-toxic and tasteless, and is an environmentally friendly chemical product. e: Protective shell shell: PC shell, tpu shell or metal shell can be used. After the raw materials are selected, the processing and production process of the mobile phone holster begins. In the bean bag leather case processing plant, all personnel who enter the workshop strictly implement the regulations of safe production management. The processing and production of mobile phone holsters have to go through a number of complicated processes to make exquisite, fashionable, high-quality, and inexpensive bean bag mobile phone holsters. Below we introduce in detail the process of manufacturing mobile phone leather cases. 2.1 Over-adhesive: First, the leather fabrics and linings that need to be produced should be overheated and melted, and save them for later use. 2.2 Opening the material, first put the selected fabric and leather finishing code, and then use a unified mold to cut the leather fabric into square sheets of the same size. Normally, you can cut out 5--10 sheets of intact fabric leather with a single cut. Normally, according to the shape and size of the mobile phone leather case, one yard of leather can be cut into about 15 to 40 pieces. 2.3 The pressing method is to press the processed leather fabric, lining and middle plate together. Place the fabric, middle board and lining in order through the finished mold. Then use the fusing machine to process the fusing voltage, and press the three together. During the pressing process, pay attention to the placement position and pay attention to the temperature control. If it is too high, it will cause the leather fabric to burn, and it will be too low. It will cause the hot melt adhesive to melt incompletely due to insufficient temperature, resulting in the problem of not firm pressing part. After pressing in this way, a semi-finished mobile phone holster is ready. In the follow-up, we only need to go through the final step of processing, and a beautiful mobile phone holster will be made successfully. 2.4 The shell material of the mobile phone protective shell used in the injection molded bean bag mobile phone holster is PC plastic, so when making the protective shell, you need to use an injection molding machine to produce the protective shell first. 2.5 After attaching the mobile phone protective shell shell, you need to attach the protective shell and the previously pressed leather case together. It can be glued through removable glue or glue, but it must be glued together. Note that the glue can not leak out, can not appear on the surface, but also pay attention to the firmness of the paste. 2.6 After the mobile phone holster part and the shell part are glued together, the mobile phone holster will naturally show an open form, so we still need to do the final step, which is the finalization. When the finalization, we need to use similar For a tool such as a hair dryer, first blow the folded part of the mobile phone holster softly, and then we want to make it into any shape, then we need to place it and press it as required. After about half an hour of finalizing measures, an exquisite mobile phone holster has been produced. 3 Quality inspection 3.1 Full inspection Transfer the produced leather case to the quality department for a comprehensive inspection, and every product that reaches the consumer is a high-quality product. 3.2 After the packaging quality inspection is completed, it needs to be transferred to the packaging department for packaging, which can be divided into simple packaging and exquisite packaging. 3.3: Sampling inspections before shipments. Sampling inspections are performed on the products before shipments. After all, it is manual inspection, so it is inevitable that there are omissions. In this way, we will conduct a random inspection process before shipment to reduce the chance of defective products leaving the factory. The lowest level. After passing this last step of random inspection, the mobile phone holster can be shipped to distributors or end consumers at all levels.
