CNC Turning & Grinding process
Turning processGrinding process
CNC Turning & Grinding process
Characteristic
- Low size allowance- Make various shape
Advantage
Weakness- Low production speed- High unit cost of production
Forging & Tapping process
HeatingForging
Forging & Tapping process
TappingCooling
Forging & Tapping process
Characteristic
- More detailed than sand mold casting- Process the iron rapidly- When mass producing → economical
Advantage
Weakness- Die is very expensive- Make simple shape only
Die casting process
Close the moldPour molten metalInjectionCooling
Die casting process
Characteristic
- Low cost, high production speed- Make complicated shape- The size is exact – quality is high
Advantage
Weakness- Using the specific machine- Die is very expensive
Injection molding process
Close the moldPour plastic powderInjectionCooling
Injection molding process
Characteristic
- Fast, using mass production- Stable quality- Can make complex shape
Advantage
Weakness- Using the specific machine- Die is very expensive
Wire drawing process
Sprinkle the oilFit through the diePull through the material
Characteristic
Wire drawing process
- More detail than rolling process- Make very thin wire- Second process needless
Advantage
Weakness- Die is very expensive- A by-product(chip) happens
