The instrument shell is the external mechanism of the equipment, which can protect its internal parts. Its materials can be divided into two categories: plastic and metal. The instrument shell made of two materials has their own advantages. Let's take a look at it

Plastic instrument shell: light weight, diversified shape, better heat dissipation effect, but low strength.

Metal instrument shell: smoother surface, higher strength, poor heat dissipation effect, rigid shape.

From the above, we can know the advantages and disadvantages of the two kinds of materials, so it is necessary to select the environment required by the equipment to select the appropriate materials
