Injection Molded Protection Case VS Rotomolded Case

2020-06-22 16:55:33

Now there are many kinds of protective case and safety cases on the market, such as injection protective cases, rotomolded aluminum alloy cases, flight cases, and so on.  protective case manufacturer - KAXIKE will tell you the difference between injection molded protective case, military rotomolded case and aluminum flight case.


1. Injection molded protection case

Injection molded protection case manufactured by injection molding process. The injection protection case is characterized by fine technology, delicate case structure, integrated case forming, waterproof, dustproof and compression resistant, and strong protective performance.

At present, PP, PP and alloy materials, ABS and other materials are generally used in injection protection case. PP material has good ductility and soft texture, so the surface of the case made of PP material will be relatively smooth, but the case texture will be relatively soft, the surface is easy to be scratched, and the protective performance is relatively poor compared with other materials. PP alloy material is a popular material at present. The main reason is that it combines the ductility of PP material and the firmness of alloy material. The case is firm, the surface is not easy to scratch, and it has good ductility, strong compression resistance and good weather resistance. Therefore, it is favored by many enterprises and military police forces.

The surface of the protective case made of ABS is smooth and well treated, but the case made of this kind of material has poor ductility, brittle case and poor compression resistance. The above is a comparison of three popular materials. Injection molding casees are usually not too large. Because of the injection molding process, too large case tension is not good, and it is not pressure resistant. Therefore, businesses in the field of injection molding rarely open too large case mold.


2. Rotomolded Case

This kind of rotomolded case technology is formed through roll plastic integration, the case wall is thick, the case is relatively bulky, usually used by military forces, so the color of the case is also made into military green. The process of this kind of case limits that the size of the case cannot be too fine, but the shock resistance and compression resistance of the case is good. Compared with the injection molding, the rolling plastic case does not need to worry about the tension of the case is not enough and it can be made into a large case, so it will be used as a transportation case for materials, equipment and equipment.


The above two kinds of casees are all molded by injection / roll molding. The existing case size cannot be changed at will. If the customized size is required, the mold opening customization is required. Therefore, the mold opening customization ability is only available to the manufacturers with mold and strong protective case.


3. Flight case

Flight case is a case with aluminum case, aluminum frame and MDF plywood board. This kind of case can be customized according to the required size without mold opening. However, the compressive and waterproof capacity of this kind of case is very general, which can not play a very good protective role, and can not carry too heavy goods. Generally speaking, it is convenient to customize, and its protection performance is relatively poor, so it can only be used as a delivery case for some items with low protection requirements.


KAXIKE safety protection case are made of improved engineering plastics, which have good weather resistance and can work in the range of - 40 ℃ ~ 95 ℃. The case can resist ultraviolet radiation, strong impact, abrasion resistance, anti-aging and flame retardancy. Waterproof and dustproof grade IP67, impervious to dust, dust-free entry, protective immersion, standard pressure time no water entry, perfect protection for instrument and equipment.
