The material selection for the factory customized inflatable phone waterproof case is extremely meticulous, aiming to ensure that the product has excellent waterproof performance, durability, and a good user experience. Common production materials include PVC (polyvinyl chloride) and ABS (acrylonitrile butadiene styrene copolymer), each with its unique characteristics. PVC material has good flexibility and transparency. Its flexibility allows the waterproof cover to tightly fit the phone, making it less likely to break due to bending during daily use, providing a stable package for the phone. High transparency allows users to clearly view the content displayed on the phone screen without removing the waterproof cover, making it convenient to operate. At the same time, PVC material itself has a certain degree of waterproofing, which can effectively prevent moisture from entering the phone. In addition, it also has good chemical corrosion resistance, which can resist some chemicals that may come into contact with daily life, such as sweat, detergents, etc., extending the service life of the waterproof cover. However, the hardness of PVC material is relatively low, and it is easy to leave scratches on the surface when scratched by sharp objects. ABS material is known for its high strength and rigidity. The waterproof cover made of this material can provide reliable physical protection for mobile phones, effectively dispersing the impact force and reducing the possibility of phone damage in case of accidental dropping or external impact. The anti-aging performance of ABS material is also excellent, and it is not easy to deform or discolor after long-term use. Moreover, it has good processing performance, making it easy for factories to carry out various complex design and molding operations, and can meet the customized needs of different customers for the appearance and structure of waterproof sleeves. However, compared to PVC material, ABS material has slightly lower flexibility and may pose certain difficulties when fitting some special shaped mobile phones. In addition to the two main materials mentioned above, some high-end customized inflatable airbag phone waterproof cases will also use other special materials or undergo material composite treatment. For example, using soft silicone material in the inner layer can not only further enhance the waterproof sealing effect, but also better protect the phone case from scratches; The outer layer is made of high-strength plastic material to enhance the overall protective performance. By selecting and matching materials reasonably, the factory can customize inflatable bag phone waterproof cases with excellent performance and quality according to the specific needs of customers. The design principle of the inflatable airbag is based on the compressibility and stability of gas, which is the core component of the factory customized inflatable phone waterproof cover. Inflatable bags are usually made of special polymer materials, which have good airtightness and elasticity. In the uninflated state, the inflatable bag is lightweight and soft, fitting the overall structure of the phone case without adding too much volume and weight, making it convenient for users to carry and use. When waterproof function is required, gas is injected into the airbag through a specific inflation device (such as a manual air pump or built-in automatic inflation system). As the gas continues to fill in, the inflatable bag gradually expands, forming an air cushion structure surrounding the phone. This air cushion structure not only provides physical support to isolate the phone from external moisture, but also utilizes the buffering performance of gas to provide shock absorption when the phone is impacted by external forces. The design of the airbag also fully considers the principle of pressure balance. Under different water pressure environments, the airbag can automatically adjust the internal air pressure to maintain relative balance with the external water pressure. For example, in deep water, as the external water pressure increases, the gas molecules inside the inflatable bag will be compressed more tightly, thereby improving the pressure resistance of the airbag and preventing it from bursting or damaging the phone due to excessive water pressure. In shallow water environments or normal air pressure environments, the inflatable bag maintains an appropriate air pressure, ensuring waterproof effect while not affecting the normal operation of the phone or causing deformation of the waterproof cover due to high air pressure. The waterproof sealing structure is crucial to ensure excellent waterproof performance of the factory customized inflatable phone waterproof cover. Generally speaking, the sealing structure of waterproof covers mainly includes the following key parts: firstly, the edge sealing design. The edges of waterproof covers are usually sealed with hot pressing or ultrasonic welding technology to tightly connect the materials of various parts together, forming a seamless whole. This sealing method can effectively prevent moisture from seeping into the edge of the waterproof cover. During the hot press sealing process, the molecular structure of the material is fused with each other through high temperature and high pressure, forming a strong sealing line; Ultrasonic welding utilizes the heat generated by high-frequency vibration to instantly melt and bond materials, ensuring the reliability of the seal. Next is the sealing treatment at the interface. For the charging interface, headphone jack, buttons and other parts of the mobile phone, the waterproof cover adopts a special sealing design. For example, the charging interface is usually equipped with a pluggable sealing plug, which is designed to fit tightly with the interface to ensure complete sealing and prevent moisture from entering when the interface is not in use. The headphone jack also has similar sealing measures, and some waterproof covers also use magnetic sealing covers, which not only have good sealing effects, but also are more convenient and fast to use. For the button part of the phone, the waterproof cover is covered with soft rubber material. The rubber material not only ensures the normal operation feel of the buttons, but also forms a good seal around the buttons to prevent moisture from seeping into the gaps between the buttons. In addition, some high-end factories also use multi-layer sealing structures to customize inflatable phone waterproof cases. An additional sealing layer is installed between the inner and outer layers of the waterproof cover to further enhance the waterproof effect. This multi-layer sealing structure is like a sturdy defense line, even if the outer seal is slightly damaged, the inner seal can continue to block the invasion of moisture, providing dual protection for the phone. Through the carefully designed inflatable bag and waterproof sealing structure mentioned above, the factory customized inflatable bag phone waterproof cover can provide reliable waterproof protection for the phone, meeting the needs of users in various water environments. The size range of factory customized inflatable phone waterproof covers is relatively wide to adapt to different sizes and styles of phones. In terms of length, it usually covers a range of 140mm to 180mm, with a width range of approximately 70mm to 95mm, and a thickness of around 10mm to 20mm depending on different design and functional requirements. These size settings are not arbitrary, but take into account the actual size of various mainstream phones on the market, and reserve a certain amount of space to accommodate the airbag and ensure that the phone can move freely inside the case, without affecting normal use due to limited space. This waterproof case has strong versatility and can be adapted to multiple brands and models of mobile phones. From the perspective of the Apple series, suitable customized waterproof cases can be found for different generations and sizes of models such as iPhone 11, iPhone 12, iPhone 13, iPhone 14, etc. For Huawei phones, the P40 and P50 of the P series, as well as the Mate 40 and Mate 50 of the Mate series, are also within the adaptation range. In addition, many popular models under brands such as Xiaomi, OPPO, VIVO, etc., such as Xiaomi 12, OPPO Find X5, VIVO X80, etc., can also be customized with inflatable bag phone waterproof cases that match them.
During the customization process, the factory will conduct precise measurements and design for each specific model of mobile phone. Not only do we need to consider the basic dimensions of the phone’s length, width, and height, but we also need to take into account details such as the size and position of the phone’s camera module, the layout of the buttons, and the curvature of the side borders. Through precise data collection and advanced manufacturing processes, we ensure that the waterproof case can perfectly fit the phone, without being too loose and causing a decrease in waterproof performance, nor will it compress or affect the normal opening and closing of the phone case due to being too tight. This meticulous customization service allows users of different models of mobile phones to enjoy high-quality waterproof protection brought by factory customized inflatable phone waterproof covers. The waterproof level of IPX waterproof level system factory customized inflatable phone waterproof cases is usually divided according to the internationally recognized IP (Ingress Protection) protection level standards. Among them, “X” represents the dustproof level that has not been clearly defined, while the second digit represents the waterproof level. The larger the value, the stronger the waterproof ability. Common waterproof levels include IPX0, IPX8, and more. Inflatable bag phone waterproof covers can often reach the higher level of IPX8. The specific meaning of IPX8 is that the waterproof case at IPX8 level can provide reliable protection for mobile phones in quite harsh water environments. Specifically, it can continuously and for a long time completely immerse the phone in water, and under certain water pressure and immersion depth conditions, it can still ensure that water does not enter the interior of the phone, thereby ensuring the normal operation of the phone. Generally speaking, inflatable bag phone waterproof cases that reach IPX8 level can support phones to soak in water at a depth of more than 1 meter for several hours or even longer. Different manufacturers’ products may vary in specific soaking depth and duration, but overall they can meet the waterproof needs of users in activities such as swimming and shallow diving. This level of waterproof performance greatly expands the usage scenarios of mobile phones, allowing users to use their phones with peace of mind in various complex water environments. In the laboratory environment, a series of simulation tests will be conducted on the factory customized inflatable phone waterproof cover according to strict standards. Firstly, there is a static immersion test, in which the waterproof cover of the installed mobile phone is completely immersed in a specific depth of water tank, and the immersion time is set according to different levels of requirements. For IPX8 level, it is usually soaked in water at a depth of more than 1 meter for several hours. During this period, closely monitor whether there are water droplets seeping into the inside of the waterproof sleeve. With the help of high-precision humidity detection equipment, once an abnormal increase in internal humidity is detected, it is determined that the waterproof sleeve is leaking water. Next is the dynamic immersion test, which simulates the dynamic conditions such as shaking and swinging that mobile phones may encounter in water. Place the waterproof case containing the mobile phone in the simulated water flow device, and simulate actual scenarios such as water flow impact during swimming and bouncing and shaking during rowing by adjusting the water flow speed, direction, and the frequency and amplitude of the device’s shaking. After a specified duration of dynamic testing, recheck the interior of the waterproof sleeve for water stains and evaluate its waterproof performance in dynamic water environments. Pressure testing is also an important part, using professional pressure testing equipment to apply varying degrees of external pressure to the waterproof sleeve, simulating the changes in water pressure it can withstand in different water depth environments. Gradually increase the pressure until it reaches or even slightly exceeds the water pressure value corresponding to the waterproof limit depth claimed by the product, and observe whether the waterproof sleeve has problems such as airbag rupture and seal leakage during the pressure change process, in order to test its waterproof reliability in high-pressure environments. In addition to laboratory simulation testing, actual scenario testing is also indispensable. We will select different types of natural water bodies, such as lakes, rivers, oceans, etc., and arrange professional testers to carry smartphones with waterproof covers for actual use testing. Testers perform various routine operations in water, such as taking photos, recording videos, answering phone calls, etc., to test whether the waterproof cover will affect the normal function of the phone in real water environments, and to observe the waterproof effect of the waterproof cover under complex water quality and flow conditions in natural water bodies. In the swimming pool scene, the focus is on testing the waterproof stability of the waterproof cover under frequent human movements and water wave impacts. Testers swim in different swimming poses in the pool, simulating the various forces that mobile phones may experience during daily swimming. After swimming a specified distance or duration, they go ashore to check the internal condition of the waterproof cover and whether the mobile phone can operate normally. For some extreme environments, such as hot spring baths, due to the presence of various minerals and chemicals in the hot spring water, the waterproof cover material may be affected. Therefore, phones with installed waterproof covers will be soaked in hot spring water for a certain period of time to observe whether the waterproof cover has problems such as material corrosion and decreased sealing performance, in order to evaluate its durability and waterproof performance in special water quality environments. Through multi-dimensional and comprehensive practical scenario testing, we ensure that the factory customized inflatable phone waterproof cover can provide reliable waterproof protection for phones in various real-life usage scenarios.

Anime enthusiasts can print their favorite anime characters and classic scenes on waterproof covers to showcase their personality and hobbies. In addition, photographic works can also serve as materials for customized patterns. Users can print their precious photos, such as beautiful scenery during travel, family and friends’ photos, on waterproof covers to give them special commemorative significance. For corporate or organizational clients, waterproof covers with brand logos, promotional slogans, event theme patterns, etc. can also be customized as promotional tools. The factory uses high-precision printing technology to accurately and delicately reproduce every detail of the pattern, ensuring bright and durable colors. Even after daily use and friction, the pattern is not easily faded or blurred. Logo customization is an important service for enterprises, businesses, or group organizations to customize the appearance of inflatable phone waterproof covers in factories. The factory has a professional design team and advanced production technology, which can accurately present the logo provided by the customer on the waterproof cover. Both simple text logos and complex graphic identifiers can be presented in a high-quality manner. During the customization process, the factory will provide customers with professional logo layout and color suggestions based on the material, color, and overall design style of the waterproof cover, ensuring the best visual effect of the logo on the waterproof cover and highlighting the brand image. At the same time, in order to ensure the durability and clarity of the logo, special printing processes and inks will be used to enable the logo to withstand the wear, friction, and water erosion of daily use, always maintaining a bright and eye-catching appearance. By customizing inflatable phone waterproof cases with exclusive logos, enterprises and organizations can effectively enhance brand awareness and influence, and play a positive role in promotion and advertising. Customized floating design is a highly practical customization option for users who frequently participate in water activities. The factory can optimize the design of the airbag or add special floating materials to make the waterproof cover have floating characteristics. When the phone accidentally falls into the water, the waterproof cover with a floating design can quickly float the phone to the surface, avoiding the phone from sinking into the water and causing difficult to retrieve losses. This design is particularly suitable for water sports in deep water areas, such as rowing, kayaking, etc., greatly increasing the chances of retrieving the phone in case of accidental drowning. To ensure smooth operation of the phone’s touch screen even when wearing a waterproof cover, the factory can optimize the touch screen sensing area of the waterproof cover in a targeted manner. By using highly sensitive touch screen materials or special treatment of the touch screen sensing layer inside the waterproof cover, the delay or insensitivity of touch screen operation caused by the obstruction of the waterproof cover can be reduced. After optimization, users can obtain a sensitive touch that is close to naked machine operation when using the waterproof case, whether it is clicking, sliding or performing various gesture operations, ensuring that they can freely take photos, record videos, switch applications, etc. underwater, fully utilizing the various functions of the phone. The anti fog function can easily generate fog on the phone screen in environments with large temperature differences, such as entering a warm and humid indoor environment from a cold outdoor environment, or removing it from the water surface after underwater use, which can affect visibility and operation. To address this issue, factories can customize waterproof covers with anti fog function. By using anti fog coating technology on the screen window of the waterproof cover or adding special breathable and moisture absorbing materials, it effectively prevents water vapor from condensing into fog on the screen surface, keeping the screen clear and visible at all times, allowing users to continue using the phone normally without frequently wiping the screen.
To enhance the appearance, texture, and durability of the waterproof cover, a series of surface treatment processes will be carried out. For waterproof covers that require customized colors, patterns, or logos, surface cleaning treatment will be carried out first to remove impurities and oil stains to ensure the subsequent printing effect. Using advanced digital printing technology for pattern and logo printing, this technology can achieve high-precision, high-resolution printing with bright and long-lasting colors. After printing is completed, a transparent wear-resistant coating will be applied on the surface to enhance the wear resistance and scratch resistance of the waterproof sleeve surface, while improving the waterproof performance. For some waterproof covers that require special textures, such as frosted texture, high gloss texture, etc., physical or chemical surface treatment methods will be used to achieve them. For example, using sandblasting technology can create a delicate frosted texture, which not only enhances the hand feel but also increases the anti slip performance; By polishing, a high gloss texture can be obtained, making the appearance of the waterproof cover more shiny. Strict quality control measures are implemented throughout the entire production process. From the moment the raw materials enter the factory, strict inspections will be conducted on each batch of materials to check whether their physical properties, chemical properties, environmental indicators, etc. meet the standard requirements. Only raw materials that pass inspection can enter the production process. On the production line, multiple quality inspection points are set up to randomly inspect the semi-finished products of each process. Using high-precision detection equipment such as coordinate measuring instruments and image measuring instruments to test the dimensional accuracy of products; Test the waterproof performance of the waterproof cover using professional equipment such as airtight detectors and hydraulic testing machines. For appearance quality, a combination of manual visual inspection and automated optical testing will be used to check for defects such as scratches, bubbles, and deformations. Before the finished product leaves the factory, a 100% full inspection will be conducted to comprehensively test the various performance indicators of the waterproof cover, including waterproof performance, airtightness of the airbag, button operation feel, touch screen sensitivity, etc. Only products that meet the standards for all testing items will be labeled as qualified and enter the packaging process. For non-conforming products, a detailed cause analysis will be conducted and corresponding corrective measures will be taken to ensure the stability and reliability of product quality. Through the rigorous manufacturing process and strict quality control measures mentioned above, the factory is able to produce high-quality and high-performance factory customized inflatable phone waterproof covers. The packaging and transportation packaging method for factory customized inflatable phone waterproof cases aims to provide comprehensive protection for the product, ensuring that it is not damaged during transportation and storage, while also showcasing product features and conveying information. For individual waterproof covers, customized plastic boxes are usually used for packaging. This plastic box has a certain strength and toughness, which can effectively prevent the waterproof cover from being squeezed and bumped. The inside of the box will be designed with special grooves according to the shape of the waterproof cover, so that the waterproof cover can fit tightly into it and avoid shaking inside the box.
