ZFENG Sheet Metal Processing

Sheet metal fabrication is a manufacturing technology that transforms metal sheets into thin-plate hardware components through cutting, bending, forming, and other processes. Its core processes include shearing, punching, bending, welding, and surface treatment, with wide applications in automotive, electronics, construction, aerospace, and other industries.We not only produce frequency converters, but also undertake various types of sheet metal processing business. We have our own laser cutting machine that can perform sheet metal manufacturing.

Design Drawings: Use CAD software to create 2D/3D drawings, specifying dimensions, shapes, and structural requirements.

Material Selection: Choose materials based on product application and cost, such as:

Cold-Rolled Steel (SPCC): Low cost, easy to form, suitable for electroplating and baking varnish parts, with thickness ≤3.2mm.

Stainless Steel: Corrosion-resistant, requires no surface treatment, but has a high cost.

Aluminum Alloy: Lightweight, surface treatments include oxidation and electroplating, suitable for heat dissipation components.

Process Planning: Determine processing sequence, equipment, and parameters. For example, laser cutting is suitable for complex shapes, while stamping is ideal for mass production.

Shearing: Used for straight-line edge cutting, with low cost but limited precision (accuracy ≤0.2mm).

Punching: Cut specific shapes via molds, with high precision (±0.1mm) but high mold costs, suitable for mass production.

Laser Cutting: High precision (±0.1mm), suitable for complex shapes and thin plates (e.g., carbon steel, stainless steel), with clean cuts.

Bending: Use bending machines to alter sheet angles, considering bending radius (to avoid material cracking) and material thickness.

Stretching: Form 3D shapes via punch pressure, such as automotive parts, avoiding excessive stretching to prevent material rupture.

Stamping: Rapid forming via molds, suitable for mass production, such as electronic device enclosures.

Welding: Arc welding, laser welding, etc., provide high joint strength and are applicable to most metal materials.

Riveting: Suitable for different materials or non-weldable scenarios, but joints are non-detachable.

Bolted Connection: Easy to disassemble but costly, suitable for components requiring frequent maintenance.

Spray Coating: Electrostatic powder coating or liquid paint, enhancing appearance and corrosion resistance, with low cost and high efficiency.

Electroplating: Improves corrosion resistance and hardness, such as zinc or nickel plating, suitable for electronic component enclosures.

Oxidation: Anodizing for aluminum, enhancing wear resistance and decorative properties, commonly used in electronic product enclosures.

Dimensional Inspection: Use calipers, coordinate measuring machines, etc., to ensure compliance with design requirements.

Surface Inspection: Check for roughness, scratches, cracks, and other defects to ensure appearance and functionality.

Mechanical Performance Testing: Test hardness, strength, toughness, and other indicators to ensure product durability.

Cold rolled sheet metal (SPCC): suitable for ordinary sheet metal parts such as chassis and brackets, with low cost and easy processing.

Stainless steel (SUS304): used for food equipment and medical devices, with strong corrosion resistance and no need for surface treatment.

Aluminum plate (6061): Lightweight, suitable for aerospace and automotive components, surface anodized treatment.

Galvanized sheet (SECC): used for electronic component casings, corrosion-resistant and cost-effective, with surface spray protection.
