Manufacturing (363)
Here’s an overview of each manufacturing process related to metalworking, particularly in the context of producing bolts, fasteners, and structural components:
Cutting
- Description: The process of separating a material into smaller pieces or specific shapes.
- Methods: Can be performed using various techniques, including sawing, shearing, laser cutting, and water jet cutting.
Threading
- Description: The process of creating helical grooves (threads) on the surface of a fastener to enable it to engage with a corresponding nut or tapped hole.
- Methods: Common methods include cutting (using taps and dies), rolling (cold forming threads), and machining.
Heading
- Description: The process of forming a head on a fastener by shaping the end of the rod or wire.
- Methods: Typically performed using a heading machine that compresses the material to create the desired shape.
Bending
- Description: The process of deforming metal into a specific angle or shape without breaking.
- Methods: Techniques include press bending, roll bending, and rotary bending.
Swedging
- Description: A process similar to heading, where the material is shaped by compressive forces to create a particular end profile.
- Methods: Often done in a die where the rod is inserted and then swaged to form a specific shape or taper.
Chamfering
- Description: The process of cutting away a right-angled edge of a component to create a sloped edge or bevel.
- Methods: Performed using milling machines, grinders, or chamfering tools.
Welding
- Description: A fabrication process that joins materials, typically metals or thermoplastics, by melting the workpieces and adding a filler material.
- Methods: Common techniques include MIG (Metal Inert Gas), TIG (Tungsten Inert Gas), and arc welding.
Plate Fabrication
- Description: The process of shaping and assembling metal plates into finished components or structures.
- Methods: Involves cutting, bending, welding, and machining to create complex shapes from flat plates.
Heat Treating
- Description: A process that alters the physical and sometimes chemical properties of a material through controlled heating and cooling.
- Methods: Includes processes like annealing, quenching, tempering, and normalization.
Galvanizing
- Description: A process that involves coating steel or iron with zinc to protect against corrosion.
- Methods: The most common method is hot-dip galvanizing, where the metal is immersed in molten zinc.
