What is the difference between sheet metal chassis and cabinet
As we all know, the outer shell of the chassis cabinet is made of sheet metal. All parts are made of stainless steel rolled plates. Cara Hardware must pay attention to a few points when inspecting the processed chassis:
To
   1. Sheet metal cabinets are not allowed to be tilted or partially crooked or twisted. The verticality of the frame column and the base is less than 1.5mm. When testing, take the upper surface of the base as the reference and the inner edge of the upper end of the column as the measuring point.
To
  2. The parallelism between the top frame and the base is less than 1mm. The detection points are the upper surface of the base and the lower surface of the top frame, which are mutually reference. It can also be detected by measuring the length of the diagonal of the six sides, the difference should not exceed 2.5mm. If there is a middle partition, the parallelism between the top frame and the base can be relaxed to 1.5mm, and the parallelism between the middle partition and the top frame or the base is less than 1mm.
To
  3. The absolute value of the difference between the diagonals of the upper and lower enclosures is less than 1.5mm.
To
  4. The uprights must not be twisted, and the parallelism between the two ends of each upright connected to the upper and lower enclosure frames and the adjacent plane of the enclosure frame is less than 0.5mm.
To
5. The slideway supporting the subrack, the working surface composed of the left and right slides on the same layer is parallel to the upper surface of the base is 1mm, and the gap between the two adjacent panels after the subrack is installed should be ensured. The absolute value shall not exceed 0.6mm.

KEALA chassis cabinets are two products. The chassis cabinet is a habitual term. Let’s learn about these two products separately. As a part of computer accessories, the main role of the chassis is to place and fix various computer accessories. A support and protection function. In addition, the computer case has an important role of shielding electromagnetic radiation. The case generally includes a shell, a bracket, various switches and indicators on the panel.
To
  The shell is made of steel plate and plastic combined with high hardness, which mainly protects the internal components of the case; the bracket is mainly used to fix the motherboard, power supply and various drives. Cabinets are generally made of cold-rolled steel plates or alloys to store computers and related control equipment. They can provide protection for storage equipment, shield electromagnetic interference, and arrange equipment in an orderly and neat manner to facilitate future maintenance of equipment. Cabinets are generally divided into server cabinets, network cabinets, console cabinets, etc.
