Sheet Metal: The Art of Metal Shaping in Industrial Manufacturing (3)

II. Sheet Metal Applications: Permeating Every Corner of Modern Life

Sheet metal technology, due to its flexibility and affordability, has become a versatile process in the industrial sector. Typical applications include the following:

1. Automotive Manufacturing: The skeleton and exterior of the vehicle body

Structural components: Doors, hoods, frame rails, and other components are formed using sheet metal stamping, accounting for over 60% of the vehicle's components.

Chassis components: Fuel tanks, mufflers, brake disc brackets, and other components require a balance between strength and lightweight (e.g., aluminum alloy sheet metal).

New Energy Vehicles: Battery housings (stainless steel or aluminum alloy sheet metal) must meet multiple requirements for impact resistance, waterproofing, and heat dissipation.

2. Aerospace: The Ultimate Challenge of Lightweight and High Precision

Aircraft skins: Utilizing aviation-grade aluminum alloy sheet metal, complex curved surfaces are achieved through CNC bending and chemical milling (etching), reducing weight while maintaining aerodynamic performance.

Engine Components: High-temperature areas such as turbine housings and exhaust pipes utilize titanium alloy sheet metal, which must withstand extreme temperatures and pressures.

3. Electronic Equipment: Protective armor for precision instruments

Chassis and Cabinets: Server casings, power distribution cabinets, industrial control equipment chassis, etc., are constructed through sheet metal bending and welding to form frames with integrated heat dissipation vents, mounting rails, and other structures.

Consumer Electronics: Laptop casings (aluminum alloy stamping and anodizing) and mobile phone mid-frames (CNC milling and sheet metal bonding), pursuing a balance between ultra-thinness and high strength.

4. Architecture and Decoration: A cross-disciplinary fusion of industry and aesthetics

Steel Curtain Walls: Metal decorative panels (such as aluminum veneer and stainless steel) on building facades are formed through sheet metal bending into wavy, perforated, and other shapes, providing both sunshade and aesthetic benefits.

Ventilation Systems: Central air conditioning ducts and exhaust pipes are fabricated from galvanized steel sheet metal, with clinching connections for quick installation.

5. Medical Devices: Guardians of Cleanliness and Safety

Surgical Equipment Housings: Stainless steel sheet metal is finely polished and electrolytically treated to meet sterile environment requirements, with a surface roughness of Ra ≤ 0.8μm.

Medical bed structure: Adjustable beds' lifting brackets, folding mechanisms, and other components require highly reliable connections through sheet metal welding.
