During the welding process of cabinet manufacturing, the welds must be firm, with the outer surface of the components fully filled and no gaps left. The welding should be neat and even, without any defects such as cracks, burrs, burn-throughs, slag, porosity, or dents.
During cabinet welding operations, it is prohibited to have slag or arc damage to parts and components. For other non-welded areas, especially externally visible ones, the slag after welding should be removed, including all kinds of particles adhering to the surface of parts and components, such as spatter.
Surface welding of parts should be leveled and polished; for those with welding surfaces on the same plane, there should be no visible bumps or dents after treatment. Welding operations for cabinets should be standardized to minimize stress, and welding should be done with proper fixtures. Deformation of parts due to welding is not permitted, and the workpieces should be corrected after welding.
During the manufacturing of cabinet enclosures, internal design should minimize painting and electroplating treatments. Previous cabinets all utilized screw-fastened designs, which required a plethora of screws and screwdrivers for installation, making disassembly and assembly a cumbersome and time-consuming task. Now, cabinets feature snap-on or hand-tightened screw designs, facilitating easy assembly and disassembly, thereby improving assembly speed.
The case has been improved both externally and internally. It now features a plug-and-play design, using plastic clips to secure internal components. Typically, cases use manual screws for assembly, allowing for disassembly without the need for a screwdriver, thereby eliminating much of the hassle associated with frequent hardware installation and removal.
Cabinets and enclosures have always prioritized heat dissipation during use, especially during the summer months. In addition to the heat generated by the equipment itself, cabinets must also withstand the challenge of external high temperatures. Elevated temperatures in cabinets are normal, as graphics cards, hard drives, and CPUs are components that generate significant heat. Adding a cooling fan should improve the heat dissipation.
Fans are suitable for indoor temperatures above ambient temperatures; however, industrial air conditioners should also be considered when internal and external recirculation is required to be isolated in enclosed environments. Air conditioners use the refrigeration principle of compression to cool, achieving constant temperature control of the internal temperature of electrical control cabinets. Since the air circulation inside and outside the electrical control cabinet is isolated, it can effectively prevent moist gases and dust from entering the cabinet.
Air conditioners are generally categorized by their installation methods: wall-mounted (including side-mounted, flush-mounted, and cabinet-mounted), and ceiling-mounted. The selection of an air conditioner is based on the temperature difference between the cabinet and the ambient temperature, as well as the cabinet's heat loss, to determine the required cooling capacity for the unit.
The cabinet assembly is now complete and in operation. To ensure smooth operation of both the cabinets and the equipment, regular maintenance and care are essential for the cabinets, which benefits the maintenance work after daily use.
Whether it's the equipment or the important auxiliary equipment, they all offer good protection. However, during the use of the cabinet, it is crucial to pay attention to its protection. It is inevitable that there will be bumps and dings during the use of the cabinet, which can lead to chipping of the paint. This will directly affect the cabinet, so it is necessary to clean the coating surface of the cabinet, ensuring it is free of dust, grease, and moisture, and kept away from fire. Avoid placing the cabinet in environments with direct sunlight exceeding 40°C.
The manufacturer of cabinet enclosures uses acid pickling and phosphating for surface treatment, followed by electrostatic powder coating and baking. The surface treatment technology is divided into indoor and outdoor powder types; the indoor cabinet enclosures are ideal for placement in dry, well-ventilated areas to ensure the powder's dryness and prevent peeling. They can be used normally in environments with humidity levels of %&0. The outdoor powder coating for cabinets can be used in damp, salty conditions for extended periods. It is recommended to wipe down the condensation from the enclosures every 1-2 months to maintain their integrity.
Proper maintenance of the cabinets can ensure their stability and the normal operation of the equipment.
