The whole process of quality control from material to finished mobile phone case factory

In the market of protective cases for digital products, mobile phone cases occupy an important position. For factories producing protective cases, quality control of the whole process is the key to win the trust of B-end customers. Taking the production of anti-drop cases as an example, every step from material to finished product is related to product quality.

Material procurement is the first stage of quality control. The factory will strictly select the materials used in the manufacture of anti-drop cases, such as high-quality silicone, TPU, etc. These materials should not only have excellent flexibility, but also have the ability to be used in the manufacturing process. These materials not only need to have excellent flexibility and abrasion resistance, but also need to have good cushioning properties to effectively resist external impacts and protect mobile phones. The purchasing department establishes long-term relationships with high-quality suppliers to ensure that each batch of raw materials meets strict quality standards.

When it comes to production, precision mould making is the key. For the production of protective cases, the mould determines the accuracy and fit of the case. When manufacturing the protective case mould, the factory applies advanced CNC processing technology to ensure that the mould dimensions are precise and accurate. During the injection process, parameters such as temperature, pressure and injection time are strictly controlled to ensure that the material fills the mould evenly, avoiding defects such as air bubbles and lack of material, and ensuring the strength and toughness of the protective case.

On the production line, the operation standard of workers also affects the quality of products. In the assembly process, for the digital product protective case protector, workers will carefully check each part to ensure that the keys, interfaces and other parts are installed accurately and do not affect the normal use of mobile phones. At the same time, the introduction of automated testing equipment, real-time monitoring of the production process, once found that the quality of the problem, immediately stop and adjust to prevent defective products into the next process.

Finished product inspection is the last line of defence for quality control. The factory will carry out a comprehensive inspection of each drop protection case, including appearance inspection, size measurement, drop test, etc.. Appearance inspection ensures that the surface of the case is smooth and free of scratches and stains; size measurement ensures that the case fits perfectly with the mobile phone; and drop test simulates the accidental drop scenarios in daily use to check the case's anti-drop performance. Only products that pass all the tests will be labelled as qualified and packed for shipment.

Through the whole process of quality control of material procurement, production process and finished product testing, the mobile phone case factory provides B-end customers with high-quality digital product protective cases and covers, meets the market demand for various types of products, such as drop-proof protective cases, and stands out in the fierce competition in the market.
