custom metal parts in China
Metal parts, around our lives, such as vehicle engine metal parts, metal brackets, and stainless steel shelves, play a vital role in solving problems of manufacture and applications and can further improve living standards. Custom metal fabrication is to create of metal parts for specific applications and industries through CNC machining, injection molding, extrusion, casting, forging, stamping, 3D printing process and so on.

As a metal parts fabricator, Sungplastic always delves into custom metal parts manufacturing and is committed to producing high-quality metal parts at a competitive price.

What is Custom Metal Parts Fabrication?

Custom metal parts fabrication refers to metal components or pieces that are manufactured to specific, non-standard specifications to meet the unique requirements of a particular project or application. These parts are typically fabricated through processes like machining, casting, forging, or additive manufacturing (3D printing), depending on the complexity and material requirements of the part. It involves the cutting, shaping, and assembling of metal materials to produce items tailored to the precise specifications of a customer or a particular project. This process often involves various techniques and tools, such as welding, cutting, bending, and machining, to transform raw metal materials into finished products.

CNC Machining

CNC Milling: Ideal for complex shapes and precise detailing.
CNC Turning: Suitable for cylindrical or symmetrical parts.

precision metal stamping

Sheet Metal Stamping

Thin metal sheets are cut, bent, and formed to create various components. Stamping uses dies to cut and shape the metal.

metal injection molding

Metal Injection Molding

Fine metal powders are mixed with a binder and injected into mold cavities, then heated to remove the binder and sinter the metal parts.

Metal Casting

Molten metal is poured into a mold to form a part’s shape. Types include sand casting, investment casting, and die casting.

Plan Your Metal Fabrication with Us.

Design and Engineering

Begins with the detailed design and engineering drawings: dimensions, materials, and specifications for the desired metal product.

Forming and Shaping

Metal pieces are then shaped and formed according to the design using processes like bending, rolling, and stamping.

Machining and Finishing

Additional machining processes, such as drilling, milling, or grinding. Surface treatments like painting, powder coating, or galvanizing.


Multiple fabricated metal components are assembled to create the final product. This may involve welding, bolting, or other joining methods.

Different Metal Materials

  • Steel: Strong, versatile, and widely used in construction and manufacturing. Types include carbon steel, stainless steel, and alloy steel.
  • Aluminum: Lightweight, corrosion-resistant, and ideal for aerospace and automotive applications.
  • Copper: Excellent electrical conductivity, used in wiring and electrical components.
  • Brass: Corrosion-resistant alloy of copper and zinc, valued for its aesthetics and low friction.
  • Bronze: Durable alloy of copper and tin, often used in sculptures and bearings.
  • Titanium: High strength-to-weight ratio, used in aerospace, medical implants, and sports equipment.
  • Nickel: Resistant to corrosion and heat, essential in the chemical and aerospace industries.
  • Stainless Steel: Corrosion-resistant and hygienic, used in kitchen appliances and medical equipment.
  • Cast Iron: Heavy and brittle, used in construction, cookware, and engine components.
  • Lead: Dense and malleable, used for radiation shielding and batteries.
  • Zinc: Corrosion-resistant, used as a protective coating (galvanization) and in die-casting.
  • Magnesium: Lightweight and strong, used in aircraft and automotive parts.
  • Tungsten: Exceptionally high melting point, used in electrical filaments and heavy machinery.
  • Hastelloy: Corrosion-resistant alloy, vital in chemical processing.

Surface Finish Options for Metal Parts

Surface finish is the final process in the manufacturing operations. It can provide aesthetics to custom metal parts.

    • Electroplating
      A metal coating is applied to the part’s surface through electrolysis. Improves corrosion resistance and appearance.
    • Electroless Plating
      Similar to electroplating but without the need for an electric current. Provides uniform coating even on complex shapes.
    • Anodic Oxidation (Anodizing)
      Forms a protective oxide layer on aluminum surfaces, enhancing corrosion resistance and providing color options.
    • Chemical Treatment
      Chemical processes like passivation and pickling can clean, treat, or modify the surface of metal parts for improved properties.
    • Vacuum Plating
      A thin layer of metal is deposited onto the part’s surface in a vacuum chamber, creating a reflective or decorative finish.
    • Hot Dipping
      The part is immersed in a bath of molten metal, forming a uniform coating. Common for galvanizing steel parts.
    • Painting
      Surface coating with paint or powder coating for corrosion protection and aesthetics.
    • Thermal Spraying
      Uses heat to melt metal or ceramic materials, which are then sprayed onto the part’s surface to create a durable coating.
