Manufacturing processes (origional 5)
A manufactuting process is how a company builds or creates products. Each manufacturer establishes their own production method based on their customer demand, materials required, assembly process, and sales forcasts.
- Discrete manufacturing - Similar to repetitive manufacturing, with the same dedicated lines but with a variation of setup and changeoper frequencies.
- Job shop manufacturing - Unlikely you will have discrete or repetitive processes. There will have dedicated areas or workstations for a single or multiple product.
- Process manufacturing (batch) - Similar to discrete, but when one batch is complete, the equipment is cleaned and readied for the next product.
- Process manufacturing (continuous) - Similar to repetitive, but the process produces raw materials like gasses, liquids, powders, and slurries.
- Repetitive manufacturing - A process that has dedicated assembly/production lines that produce the same item/items 24/7, all year round.
Manufacturing processes (other types)
- Additive - A 3D printing process. There are more types of 3D printing.
- Fused deposition (FDM) - These printers use a thermoplastic filament, which is heated to its melting point and then extruded.
- Stereolithography (SLA) - Uses a vat of liquid photopolymers resin that can be cured. The build plate moves in small increments and the liquid polymer is exposed to light where the UV lasier draws a cross-section layer by layer.
- Casting - Pouring of material into a mold.
- Centrifugal - A molten material is poured into a circular mold rotating around its center axis.
- Die - Molten metal entering a cavity under pressure.
- Investment - A wax casting is made and used to create a mold from the master pattern.
- Forming - The metal is subjected to heavy loads to permanently deform without adding or removing the material.
- Bending - Process creating U-shaped or V-shaped bends on a material.
- Compressive - Compression stress is applied to the material resulting in an alteration of the shape.
- Shearing - Altering the metal shape with shear force.
- Tensile - An applied stress to a material resulting in stretching of the material.
- Joining - When components are joined togeather temporarily or permanently.
- Machining - A material removal process where the raw material is shaped into the desired product.
- Moulding - Shaping liquid or pliable raw materials using a mold.
- Painting and labeling - This is what happens at the end of the manufacturing process.
- Inkjet printer - A process that deposits tiny drops of ink rom a nozzle onto paper from a moving carriage assembly.
- Laser engraving - A concentrated beam of light that cuts through the material creating a detailed shape.
- Rotary engraving - A rotary tool cuts away the material creating the desired shape.
