The die-cast aluminum housing can be made in different shapes, convenient for connecting in various directions, with high hardness and strength, and can be mixed with zinc to form a zinc aluminum alloy.
On the other hand, in the die-cast aluminum production process, the mold cost is very expensive, higher than other molds such as injection molds. At the same time, mold maintenance is very difficult, and it is difficult to reduce materials to repair when design errors are made. And each time the production process reaches a certain amount, the cost is low, the polishing is more complicated, the production cycle is slow, and the product cost is about 3 times higher than that of injection molded parts. The screw hole should be larger (4.5mm in diameter) for the connection force to be stable.
