Primary Processing Materials

Aluminum and Aluminum Alloys

Aluminum alloys are commonly used in custom sheet metal fabrication due to their light weight, corrosion resistance, and excellent machinability.

Common materials include:

Aluminum 5052
Aluminum 6061
Aluminum 6063
Aluminum 6082
Aluminum 7075

Suitable for equipment housings, brackets, panels, frames, and lightweight structural components.

Stainless Steel

Suitable for industrial parts requiring high strength, corrosion resistance, and surface stability.

Common materials include 304, 316, 303, and 17-4PH.

Carbon Steel and Alloy Steel

Suitable for machinery brackets, bases, frames, structural components, and welded assemblies.

Copper and Brass

Suitable for electronic, electrical, and conductive structural components; can undergo sheet metal fabrication and subsequent processing based on project requirements.

Integrated Stamping, Bending, and Welding

For complex sheet metal structures, Hongsinn Precision combines various manufacturing processes based on product design:

Material Blanking → Stamping → Bending → CNC Machining → Welding → Grinding/Deburring → Surface Treatment → Precision Inspection

This integrated manufacturing approach is suitable for OEM sheet metal products requiring a combination of:

Precision mounting holes
Multi-angle bends
Stamped structural features
Threaded holes
Welded connections
Complex assembly structures
