When choosing an industrial computer, some customers care about the processor, some focus on the interface, but some customers look at the shell first. It seems that the difference is just the material, but in fact it is an important watershed behind the product stability, environmental adaptability and life cycle.
Industrial computers are turned on all year round, and whether the heat dissipation can keep up is related to whether the motherboard and power supply can run stably. Plastic shells dissipate heat slowly, and heat easily accumulates inside the shell. If the computer runs in a high temperature environment for a short time, it may freeze or reduce the frequency. Metal shells conduct heat quickly and can also be used as heat sinks, which can keep the core temperature from soaring even in continuous operation.
The structural strength is different, and the impact resistance is completely not at the same level
The factory site is not an office, and handling, installation, and collisions may occur. The plastic shell is light but brittle, and it is easy to crack if it falls, and the screw holes will loosen after being screwed a few times. The metal shell is resistant to pressure and impact, and it is not easy to be damaged even if it is hung on a forklift or installed on automatic equipment. It is worth mentioning that the Kongxian G1 industrial control all-in-one computer uses an integrated aluminum alloy shell, which performs particularly stably outdoors and on mobile devices. As an industrial control all-in-one computer manufacturer focusing on industrial environments, this design logic is derived from a large amount of actual usage feedback.
Metal shells can also help devices block external electromagnetic interference. There are inverters, motors, and wireless devices in the workshop, and signal interference is common. The metal shell itself can form a shielding layer to reduce the instability caused by electrostatic interference and electromagnetic radiation. If the plastic shell does not have additional protection, it is easy to cause touch failure, screen flickering and other problems in a high-interference environment.
The game between cost and weight also has scenario considerations
The biggest advantage of plastic shells is their low cost and light weight, which makes them suitable for low-load environments. Metal shells are relatively expensive, heavier, and have higher transportation costs and structural installation requirements. When configuring project plans, Kongxian Technology will give reasonable suggestions based on the customer's usage intensity and installation conditions. For some lightweight scenarios, local metal reinforcement solutions will be used to balance price and stability.
The shell is not an accessory, it is the "first line of defense" of the industrial control all-in-one computer. Long-term use, stable operation, and environmental resistance are often hidden in this layer of material. Only by finding an industrial control all-in-one computer manufacturer that understands structural design and is familiar with on-site applications can you choose clearly between metal and plastic and use it with confidence.
