Parts Manufacturing Processes

Comprehensive guide to modern manufacturing methods, from traditional casting to advanced additive manufacturing techniques.

Die Casting
Die Casting
Metal Casting

A metal casting process that forces molten metal under high pressure into mold cavities. The process uses two hardened tool steel dies which have been machined into shape and work similarly to an injection mold during the process.

Key Advantages

  • High precision and dimensional accuracy
  • Excellent surface finish
  • High production rates

Common Applications

  • Automotive engine blocks
  • Aerospace components
  • Electronics housings
Forging
Forging
Metal Forming

A manufacturing process involving the shaping of metal using localized compressive forces. The blows are delivered with a hammer or a die. Forging is often classified according to the temperature at which it is performed.

Key Advantages

  • Superior mechanical properties
  • Improved grain structure
  • High strength-to-weight ratio

Common Applications

  • Automotive crankshafts
  • Aircraft landing gear
  • Hand tools
Sand Casting
Sand Casting
Metal Casting

A metal casting process characterized by using sand as the mold material. The term 'sand casting' can also refer to an object produced via the sand casting process. Sand castings are produced in specialized factories called foundries.

Key Advantages

  • Low tooling costs
  • Suitable for complex shapes
  • Wide range of sizes

Common Applications

  • Engine blocks
  • Machine tool bases
  • Pump housings
Gravity Casting (Permanent Mold)

A casting process that uses gravity to fill a permanent, reusable mold with molten metal. Also known as permanent mold casting, this process produces parts with better dimensional accuracy and surface finish compared to sand casting.

Key Advantages

  • Better surface finish than sand casting
  • Improved dimensional accuracy
  • Reusable molds

Common Applications

  • Automotive pistons
  • Cylinder heads
  • Valve components
Aluminum Extrusion
Aluminum Extrusion
Metal Forming

A process by which aluminum alloy material is forced through a die with a specific cross-sectional profile. The force applied creates the desired shape as the material emerges from the die opening.

Key Advantages

  • Complex cross-sections possible
  • Excellent surface finish
  • High strength-to-weight ratio

Common Applications

  • Architectural frames
  • Automotive structures
  • Aerospace components
Stamping
Stamping
Sheet Metal

A cold-forming process that uses dies and stamping presses to convert sheet metal into net shape. The process can include punching, blanking, embossing, bending, flanging, and coining operations.

Key Advantages

  • High production rates
  • Excellent repeatability
  • Complex shapes in single operation

Common Applications

  • Automotive body panels
  • Electronic enclosures
  • Appliance components
Deep Drawing
Deep Drawing
Sheet Metal

A sheet metal forming process used industrially to produce cup-shaped, box-shaped, and other complex-curved hollow-shaped sheet parts. The depth of the drawn part exceeds its diameter.

Key Advantages

  • Seamless hollow parts
  • High strength components
  • Excellent surface finish

Common Applications

  • Automotive fuel tanks
  • Kitchen sinks
  • Cookware
Sheet Metal Fabrication

A comprehensive manufacturing process that involves cutting, bending, welding, and assembling metal sheets to create finished products. It encompasses various techniques to transform flat metal sheets into complex structures.

Key Advantages

  • Design flexibility

  • Cost-effective prototyping

Common Applications

  • HVAC ductwork
  • Electronic enclosures
  • Architectural panels
Welding and Fabrication

A fabrication process that joins materials by using high heat to melt the parts together and allowing them to cool, causing fusion. Fabrication encompasses the entire process of constructing products by cutting, bending, and assembling components.

Key Advantages

  • Strong permanent joints
  • Versatile material compatibility
  • Cost-effective joining

Common Applications

  • Structural steel construction
  • Automotive chassis
  • Shipbuilding
CNC Machining
CNC Machining
Subtractive Manufacturing

A subtractive manufacturing process that utilizes computerized controls and machine tools to remove layers of material from a stock piece to create custom-designed parts and products with high precision.

Key Advantages

  • Extremely high precision
  • Excellent repeatability
  • Complex geometries

Common Applications

  • Aerospace components
  • Medical devices
  • Automotive parts
MIM (Metal Injection Molding)

A manufacturing process that combines the design flexibility of plastic injection molding with the strength and integrity of wrought metals. It uses fine metal powders mixed with a binder system to create complex parts.

Key Advantages

  • Complex geometries
  • High precision
  • Near-wrought properties

Common Applications

  • Medical instruments
  • Automotive sensors
  • Firearms components
Roll Forming
Roll Forming
Metal Forming

A continuous metal forming process that converts sheet metal into engineered shapes using consecutive sets of mated rolls. The process gradually bends a strip of metal into a desired profile.

Key Advantages

  • High speed production
  • Cost-effective for long runs
  • Complex profiles possible

Common Applications

  • Roofing panels
  • Structural framing
  • Automotive components
Plastic Injection Molding
Plastic Injection Molding
Plastic Processing

A manufacturing process that produces plastic parts by injecting molten plastic material into a mold cavity. It's one of the most widely used manufacturing processes for producing plastic components in high volumes.

Key Advantages
