  1. Manufacturing process Electric motor B. S. Kim , J. Y. Kim , T. M. Kim , K. U. Min D. H. Park , D.J. Bang , S.H. Yoon

  2. Table of contents W H Y ? Why engineer used the manufacturing process? ↙ H O W ? How are the manufacturing process conducting ? ↘

  3. Parts of manufacturing Rotator Fan Fan cover Support Stator Bolt Al cover

  4. Parts of manufacturing CNC Casting Injection Forging Drawing

  5. CNC Turning & Grinding process Turning process Grinding process

  6. CNC Turning & Grinding process Characteristic Advantage - Low size allowance - Make various shape Weakness • Low production speed • High unit cost of production

  7. Forging & Tapping process Heating Forging

  8. Forging & Tapping process Cooling Tapping

  9. Forging & Tapping process Characteristic Advantage - More detailed than sand mold casting - Process the iron rapidly - When mass producing → economical Weakness • Die is very expensive • Make simple shape only

  10. Die casting process Close the mold Pour molten metal Injection Cooling

  11. Die casting process Characteristic Advantage - Low cost, high production speed - Make complicated shape - The size is exact – quality is high Weakness • Using the specific machine • Die is very expensive

  12. Injection molding process Close the mold Pour plastic powder Injection Cooling

  13. Injection molding process Characteristic Advantage - Fast, using mass production - Stable quality - Can make complex shape Weakness • Using the specific machine • Die is very expensive

  14. Wire drawing process Sprinkle the oil Fit through the die Pull through the material

  15. Wire drawing process Characteristic Advantage - More detail than rolling process - Make very thin wire - Second process needless Weakness • Die is very expensive • A by-product(chip) happens
