Custom Metal Fabrication | Overview

Custom metal fabrication involves a variety of processes used to shape, cut, and assemble metal structures into desÑ–re forms and sizes. Each method offers unique characteristics and is suited for different applications. Here, we discuss the most prevalent custom metal fabrication methods, detailing their characteristics.

Cutting

Cutting involves slicing metal into smaller sections using advanced tools and equipment. In case of sheet metal, a different sheet metal fabrication equipment like mechanical saw is used for cutting and shaping metal sheet into a desired dimension.

• Tools: Lasers, plasma torches, water jets, or mechanical saws.
• Characteristics:
  • High precision and accuracy.
  • Can handle a wide range of metal thicknesses.
  • Suitable for both straight and intricate cuts.

Bending

Bending reshapes metal into desired angles and forms without cutting.

• Tools: Press brakes, folding machines, and other mechanical tools.
• Characteristics:
  • Maintains material integrity by not removing parts.
  • Can create complex shapes and angles.
  • Often used in conjunction with other processes.

Machining

Machining involves removing unwanted material to shape metal into the desired form.

• Tools: Lathes, mills, drills, and CNC machines.
• Characteristics:
  • High precision and ability to create complex geometries.
  • Suitable for producing detailed components.
  • Can be costly due to tool wear and maintenance.

Forging

Forging shapes metal by applying compressive forces.

• Tools: Hammers, presses, and anvils.
• Characteristics:
  • Produces very strong components due to grain refinement.
  • Often used for parts requiring high durability.
  • Can handle large volumes and heavy metals.

  • Casting

    Casting involves pouring liquid metal into molds where it solidifies into the desired shape.
    • Tools: Furnaces, molds, and casting machines.
    • Characteristics:
      • Ideal for complex shapes and large production runs.
      • Cost-effective for mass production.
      • Some limitations in terms of material strength.

    Extrusion

    Extrusion forces metal through a die to create long shapes with a uniform cross-section.
    • Tools: Extrusion presses and dies.
    • Characteristics:
      • Produces consistent and continuous cross-sectional profiles.
      • Efficient for creating pipes, tubes, and custom profiles.
      • Limited to shapes of a uniform cross-section.

    Drawing

    Drawing pulls metal through a die to reduce its diameter.
    • Tools: Drawing dies and draw benches.
    • Characteristics:
      • Enhances strength and surface finish of the metal.
      • Effective for producing wires, rods, and tubes.
      • Allows precise control over material thickness.

    Punching

    Punching removes specific sections of metal using a punch and die setup.
    • Tools: Punch presses.
    • Characteristics:
      • Ideal for creating holes, slots, and shapes in sheet metal.
      • Fast and efficient for repetitive tasks.
      • Limited to relatively thin sheets of metal.

    Stamping

    Stamping shapes metal by pressing it between two dies.
    • Tools: Stamping presses.
    • Characteristics:
      • Efficient for high-volume production.
      • Capable of producing complex and detailed parts.
      • Can work with a variety of materials and thicknesses.

      • Shearing

        Shearing cuts metal sheets without forming chips or using burning/melting processes.
        • Tools: Shear machines and guillotine cutters.
        • Characteristics:
          • Fast and efficient for straight cuts.
          • Suitable for high-volume sheet metal processing.
          • Limited to cutting straight lines only.

        Welding

        Welding joins two or more metal pieces using heat, pressure, or both.
        • Tools: MIG welders, TIG welders, arc welders, and soldering tools.
        • Characteristics:
          • Creates strong and permanent bonds.
          • Applicable for a wide range of metals and thicknesses.
          • Essential for assembling fabricated parts into final products.
