- 1Sand CastingLiquid metal poured into split sand mold
- 2Die CastingLiquid forced under pressure into metal mold
- 3Investment CastingWax pattern embedded in refractory, melted out, and cavity is filled with metal
- 4Low pressure castingDie is filled from below, giving control of atmosphere and of the flow of metal into the die
- 5Injection moldingGranular polymer (or filled polymer) is heated, compressed, and sheared by a screw feeder, forcing it into the mold cavity
- 6Blow moldingTubular blank of hot polymer or glass is expanded by gas pressure against the inner wall of a die
- 7Polymer extrusionShaped sections are formed by extrusion through a shaped die
- 8Thermo-formingSheet of thermoplastic is heated and deformed into a die by vacuum or gas pressure
- 9ForgingSlug of metal is shaped between two dies held in the jaws of a press
- 10RollingBillet or bar is reduced in section by compressive deformation between the rolls
- 11ExtrusionMetal is forced to flow through a die aperture to give a continuous prismatic shape. Can be hot (T > 0.85 Tm ) warm (0.55 Tm < T < 0.85 Tm ), or cold (T < 0.35 Tm ).
Hot work produces larger shape changes but gives poorer surface and tolerance (oxidation, warpage)
- 12SpinningSpinning disc of ductile metal is shaped over a pattern by repeated sweeps of the smooth, rounded tool
- 13Die pressing and sinteringPowder is compacted in a die, often with a binder, and the green compact is then fired to change the density
- 14Hot isostatic pressingPowder in a thin, shaped shell or preform is heated and compressed by an external gas pressure
- 15Powder injection moldingPowder and binder are forced into a die to give a green blank that is then fired
- 16Slip CastingWater-based powder slurry is poured into a porous plaster mold that absorbs the water, leaving a powder shell that is subsequently fired
- 17Filament windingFibers of glass, Kevlar, or carbon are wound onto a former and impregnated with a resin-hardener mix
- 18Roll and spray lay-upFiber reinforcement is laid up in a mold onto which the resin-hardener mix is rolled or sprayed
- 19Pressure bag moldingLaid-up fiber reinforcement, impregnated with resin-hardener mix, is compressed and heated to cause polymerization
- 20PultrusionFibers are fed through a resin bath into a heated die to form continuous prismatic section
- 21Deposition ModellingSolid body is created by the layer-by-layer deposition of polymer droplets
- 22StereolithographySolid shape is created layer by layer by laser-induced polymerization of a resin
- 23Direct mold modellingSand mold is built up layer by layer by selective spraying of a binder from a scanning print-head
- 24Laser metal depositionMetal powder is fed onto the part surfaces where it is selectively sintered by a laser beam
- 25Turning and MillingThe sharp, hardened tip of a tool cuts a chip from the work piece surface
- 26Plasma cuttingHigh-energy beam of ionized gas selectively melts a slot thorough a conducting workpiece
- 27Electric Discharge Machining____ between a graphite electrode and the work piece, submerged in a dielectric such as paraffin, erodes the work piece to the desired shape
- 28Water jet cuttingAn abrasive entrained in a high-speed water jet erodes the material in its path
- 29Adhesive bondingFilm of adhesive is applied to one surface, which is then pressed onto the mating one
- 30FasteningAchieved by bolting; riveting; stapling; push-through snap fastening; push-on snap fastening; or rod-to-sheet snap fastening
- 31Metal fusion arc weldingMetal is melted, and more is added from a filler rod to give a bond or coating
- 32Hot bar polymer weldingHeat is applied to the polymer components, which are simultaneously pressed together to form a bond
- 33Paint sprayingPigment in an organic- or water-based solvent is sprayed onto the surface to be decorated
- 34Polymer powder coatingLayer of thermoplastic is deposited on the surface by direct spraying in a gas flame, or by immersing the hot work piece in a bed of powder
- 35Silk screen printingInk is wiped onto the surface through a screen onto which a blocking pattern has been deposited, allowing ink to pass in selected areas only
- 36Pad printingInked pattern is picked up on a rubber pad and applied to the surface, which can be curved or irregular
