Industry development and basic product requirements
Against the backdrop of continuous promotion of cloud computing and data center construction, the demand for Server rack cabinets in China has been increasing year by year. According to relevant data, the number of Network racks in use nationwide from 2017 to 2019 reached 1.66 million, 2.262 million, and 3.145 million respectively. With the maturity of new generation network technologies such as 5G, the industry as a whole will continue to maintain a steady growth trend.
Data cabinets are mostly floor standing rectangular structures composed of frames and cabinet doors. They not only require sufficient rigidity and strength, but also need to achieve functions such as electromagnetic isolation, grounding noise reduction, ventilation and heat dissipation. At the same time, they must meet conditions such as vibration resistance, impact resistance, corrosion resistance, dust and water resistance, and radiation resistance to ensure long-term stable operation of internal equipment.
Overview of product classification and Non standard processing
Server rack cabinets are mainly divided into two categories: standard cabinets and non-standard cabinets. Standard cabinets have unified industry standards or national and international standards, with relatively fixed structural dimensions and production forms. Common types include 19 inch network cabinets, DC screen protection cabinets for the power industry, high and low voltage power cabinets, etc.
Non standard Data center rack is designed for personalized scenario requirements and belongs to the category of sheet metal processing. It needs to be formed through cutting, stamping, bending, assembly and other processes according to the specifications and parameters provided by the customer, and combined with corresponding surface treatments to ultimately meet customized usage requirements.
Detailed explanation of core mechanical processing technology
Comms cabinet sheet metal processing mainly includes five key processes. Hot cutting is commonly used for plates or complex shapes that are difficult to process with conventional cutting and punching. Plasma cutting and laser cutting are commonly used in the industry, with laser cutting having higher precision and better forming effects.
The mechanical cutting of Computer racks mainly involves cutting and die-cutting, and cold cutting is achieved through the combination of punches and molds, without producing combustion or melting; Stamping relies on punching machines and specialized molds to process structures such as circular holes, elongated holes, and convex platforms, with high precision but more suitable for large-scale production; Bending is the process of cold pressing metal sheets using a bending machine, which is difficult and requires full consideration of sheet properties and equipment limitations; Assembly is a later forming process, and the welded parts need to maintain a clean surface. The sprayed parts are mostly assembled using riveting and bolt connection methods.
Key points of surface treatment process and process selection
Electrostatic powder coating is the most commonly used surface treatment process for 42u server racks, and is the preferred solution in scenarios without special anti-corrosion requirements. This process uses solid powder coatings as raw materials, which are uniformly attached to the surface of the workpiece through electrostatic adsorption. After heating, melting, leveling, and solidification, a uniform and hard protective coating is formed, which combines aesthetics and corrosion resistance.
Due to the advantages and disadvantages of different processing techniques, as well as differences in customer needs, when producing and selecting Wall mount server racks, it is necessary to consider batch size, accuracy, and usage environment comprehensively, and reasonably match cutting, bending, spraying and other processes to ensure the quality and performance of the finished cabinet products.
