China Sheet Metal Processing Manufacturer, Supplier, Factory

Overview:

Sheet Metal Processing is a key process for plastic forming of thin sheet materials (usually ≤6mm thick) in the metal manufacturing field, which is widely used in the production of various types of metal structural components and functional parts. The core of the process is to process the metal sheet into the desired shape through specific processes and to satisfy the requirements of strength, precision and functionality.

Application Areas:

Industrial equipment: electric control cabinets, machine tool shields, ventilation ducts, etc. .

Transportation: automobile body panels, aerospace thin-walled structural parts (such as fuel tanks, cabin).

Consumer electronics: appliance shells, server chassis and other precision parts.

Medical equipment: Instrument housings and supports that require high cleanliness and corrosion resistance.

Standards and production processes:

Production process:

Unloading: cut the plate into the required shape by shearing machine, laser cutting, CNC punching machine, etc., of which the laser cutting precision can reach ±0.1mm, applicable to complex shaped parts.

Bending: use bending machine and mold to fold flat sheet into a body structure.

Stamping and molding: covering punching, stretching, embossing and other processes.

Welding and assembly: using argon arc welding, spot welding or robot welding technology to connect the components, and then riveting and screwing to complete the assembly, to ensure the stability of the structure.

Surface treatment: including plastic spraying, electroplating, oxidizing and other processes to enhance corrosion resistance and aesthetics.

Manufacturing standards: follow GB/T and ISO standards, e.g. welded linear tolerance ±0.3mm to ±5.0mm (depending on size range), surface roughness Ra6.3-12.5
