CNC Turning & Grinding process

Characteristic

- Low size allowance- Make various shape

Advantage

Weakness- Low production speed- High unit cost of production

Forging & Tapping process

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
