The ordinary waterproof junction box is injection molded by ABS engineering plastic, which is dustproof, waterproof, anti-corrosive, insulating and impact resistant. The upper cover fastening screw is designed to have a high degree of protection outside the waterproof groove. The internal installation points provide maximum convenience for the installation of the track, circuit board, power module and expansion base. For the convenience of installation outside the equipment, concealed screw holes are left at the four corners of the waterproof junction box. Some models are available with a PC transparent cover. Up to dozens of sizes can provide solutions for petrochemical plants, terminals, sewage treatment plants, electroplating plants, gardens, residential lighting, rail transit and more. The cast aluminum waterproof junction box is die casted from silicon aluminum alloy (AlSi12). The phosphating spray surface treatment process makes the cast aluminum waterproof box have strong environmental adaptability. Due to the nature of the metal itself, the cast aluminum junction box has the characteristics of heat dissipation, antistatic, and flame retardant compared to the same type of plastic junction box. The operating temperature of -40 ° C - 120 ° C can better adapt to the high and low temperature environment where the equipment is located. Most products are equipped with metal hanging feet to facilitate the wall fixing of the equipment. The bottom mounting bosses are pre-formed with threads for component mounting, and the internal mounting points can also be used for grounding electrical equipment housings.
In summary, we can know that there is a big difference between the ordinary waterproof box and the cast aluminum waterproof box. Because of its different performance, the specific use is different.
