The core function of sheet metal housings in equipment is to provide structural support, physical protection,
and environmental isolation, while also considering electromagnetic compatibility and aesthetics.
Main Functions
Structural Support and Fixing – Forms the main frame of the equipment, bearing weight and precisely positioning internal components (such as circuit boards and transmission mechanisms), ensuring assembly stability.
Multiple Protections
Physical Protection: Blocks foreign objects (chips, dust), prevents personnel from contacting dangerous moving parts; Environmental Protection: Achieves dust and water resistance through sealed design (common IP55/IP65 rating), corrosion resistance (e.g., 304 stainless steel suitable for high salt spray environments); Electromagnetic Shielding: Blocks internal and external electromagnetic interference, ensuring EMC compliance for communication/medical/testing equipment.
Safety and Lifespan Improvement
Isolates mechanical vibration, reducing damage to internal components; in some industrial scenarios, it can extend equipment lifespan by 20%–35%.
Lightweight and Cost Balance
Thin metal sheets reduce overall weight while maintaining strength, suitable for automotive, aerospace, and portable equipment; mature technology facilitates mass production and cost reduction.
Appearance and Integration Optimization
Supports standardized/customized designs (primarily simple flat surfaces), integrating wiring channels, locks, and ventilation holes to improve human-machine interaction and installation efficiency.
Typical Application Scenarios
Industrial: Machine tool protective covers, electrical cabinets, automated production line enclosures
Electronics: Server chassis, network cabinets, industrial control computer enclosures
Consumer: Self-service terminals (vending machines/turnstiles), charging piles, medical equipment enclosures
Of course, specific performance requires comprehensive evaluation based on materials (cold-rolled steel/stainless steel/aluminum), processes (laser cutting + bending + welding), and surface treatments (conductive spraying/anti-corrosion coating); outdoor or special working conditions require specific protection levels and material corrosion resistance requirements.
