In the mobile phone accessories market, consistency of product quality is a key factor affecting user retention. Then, one of the factors affecting the quality and durability of mobile phone cases is their uniform thickness. Uniform thickness ensures that the mobile phone case fits perfectly with the phone, enhancing its protection performance, aesthetics and overall user experience. Topstar can provide you with injection molding solutions for different industries. Among the different series, the TM ll phone case maker machine can produce mobile phone cases with precise and uniform thickness. In the blog post, we will tell you how these machines achieve this level of precision.

Relationship between material selection and uniform thickness

Material selection directly affects flow behaviour, cooling rate and overall formability, all of which affect the thickness uniformity of the final product. Manufacturers commonly use TPE, TPU, and PC in mobile phone case production because of their flexibility, durability, and easy formability. The choice of material affects the mechanical properties of the mobile phone case. Uniform thickness is about aesthetics and ensuring the mobile phone case can provide consistent protection against impact and wear. If some areas of the material are too thick and others are too thin, it creates weak points that are more easily damaged. Furthermore, the use of additives or fillers in the material can affect its flow characteristics and, thus, the uniformity of thickness.

The impact of mold design on the uniformity of thickness of phone case maker machine

Mold design directly affects how the material flows into the mold cavity and how it cools, which in turn affects the thickness of the final product. First of all, the design of the mold cavity itself is very important. The TM ll series phone case maker machine has a new mechanism to achieve a one-button automatic and precise mould adjustment. You can accurately control the material flow to ensure it flows evenly and fills the entire mold. In addition, in the cooling channel, auxiliary equipment such as the mold temperature controller and the ice water machine can adjust the mold temperature well and ensure uniform material cooling. The mold temperature controller can accurately control the temperature to maintain consistency throughout the mold, thereby achieving thickness consistency.

How to achieve uniform thickness of mobile phone case in molding process

The injection molding process includes various aspects, including injection speed, pressure and cooling speed. These factors directly affect how the material flows into the mold and solidifies, ultimately determining the final product’s thickness.

Injection speed and pressure are the two most critical parameters in the molding process. If the speed is too high, it will cause uneven material flow, resulting in thickness changes. On the contrary, if the speed is too low, the material may be unable to fill the mold, resulting in thin spots or incomplete filling. The Topstar mobile phone case manufacturing machine uses oblique double shot shifts and linear guides to stabilise the injection. It can precisely control the injection speed to ensure uniform material flow.

For pressure control, the use of proportional back pressure control can achieve multi-stage back pressure settings, improve plasticization quality, and more accurately press the material into all areas of the mold, including complex details and thin parts, to achieve uniform thickness. As for the cooling speed, as mentioned in the previous paragraph, auxiliary equipment such as mold temperature controller and ice water machine ensure uniform temperature and uniform cooling and solidification throughout the mold to prevent warping or shrinkage and avoid thickness variations.

Advanced technology used in phone case maker machine

One of the most obvious technological advances of Topstar’s mobile phone case making machine is the secondary development of the self-developed control system, which makes the computer operation interface more user-friendly. These systems allow mobile phone case manufacturers to monitor key real-time process parameters such as injection pressure, temperature and flow rate. If any deviation from the optimal setting is detected, the system can automatically adjust the machine’s settings to correct the problem and ensure uniform thickness.

Another important technology is using KEBA controllers, Phish motors, and Delta drives in combination with self-developed control programs to make production control more precise and more accurate in controlling the speed and pressure of material injection. This ensures that the material flows evenly and fills the mold. This makes the thickness of the entire phone case more consistent.

Benefits of uniform thickness of mobile phone cases

One of the main benefits of maintaining uniform thickness is improved product quality. Mobile phone cases with uniform thickness are less likely to have weak points or vulnerable areas. As a result, this makes the product more durable and better able to protect the phone from impacts, falls, and daily wear and tear. At the same time, uniform thickness helps improve fit and yield. Only by accurately fitting the contours of the mobile phone can you ensure a safe fit. Thickness variations may cause problems such as looseness, gaps, or misalignment, affecting the mobile phone case’s protective performance and appearance. Topstar’s phone case maker machine helps produce a perfectly fitting and professional-looking mobile phone case, improving the overall user experience.

Better user experience through uniform thickness

In producing mobile phone cases, by using Topstar’s TM ll series phone case maker machine, every aspect of the molding process can be precisely controlled to ensure that your mobile phone case always has uniform thickness and the highest quality. Whether you produce cases for smartphones, tablets, or other mobile devices, our solutions can help you achieve your manufacturing goals and exceed customer expectations.
