What should be paid attention to when spraying oil on the liquid silicone shell of the magnetic wireless power bank
Wireless power banks, as a portable charging device, have become an indispensable part of daily life. In order to enhance the appearance and texture of the injection molded plastic shell of wireless power banks, many mobile power banks use injection molded plastic shells and undergo oil spraying treatment. However, some details and precautions need to be taken during the fuel injection process to ensure the quality and service life of the casing. Yingtai Factory will introduce some precautions regarding the spray of liquid coating on wireless power banks.
Firstly, choosing the appropriate fuel injection material is crucial. There are various coatings available on the market to choose from, but it is important to ensure that materials with good wear resistance and corrosion resistance are selected. In addition, the coating should have good adhesion to ensure that there will be no peeling, fading, or cracking issues after prolonged use.
Secondly, before conducting fuel injection treatment, it is necessary to thoroughly clean and polish the waterproof coating of the mobile power bank. This can be achieved by using appropriate cleaning agents and polishing tools. Cleaning and polishing can remove surface dirt and oxide layers, allowing the coating to better adhere to the surface of the casing.
During the fuel injection process, attention should be paid to the thickness and uniformity of the spray. An excessively thick coating may cause unevenness or bubble formation on the surface of the power bank casing, while an excessively thin coating may not provide sufficient protection. In addition, the spraying should be uniform to avoid color differences, black spots, or foreign object coverage.
In addition, appropriate drying and curing treatment is required after fuel injection. This can be achieved by placing the casing in a well ventilated environment and controlling the drying time and temperature according to the coating manufacturer's recommendations. Proper drying and curing can ensure that the coating has good hardness and durability.
When using a mobile power bank, avoid using sharp objects or chemicals to scratch or corrode the casing. At the same time, regularly cleaning the surface of the outer shell and avoiding prolonged exposure to high temperatures or humid environments can extend the service life of the waterproof case of the mobile magnetic power bank.
In summary, when spraying oil on the rubber casing of a magnetic power bank, we need to choose suitable spraying materials, thoroughly clean and polish, pay attention to the thickness and uniformity of the spraying, perform appropriate drying and curing treatments, and keep the casing clean and avoid damage during use. These precautions will help ensure the quality and durability of the liquid silicone waterproof case for wireless power banks, enhancing the user experience.
