Forging

Drawing


Manufacturing process

CNC Turning & Grinding process

Turning process

Grinding process


Manufacturing process

CNC Turning & Grinding process

Characteristic

Advantage

- Low size allowance

- Make various shape

Weakness

  • Low production speed

  • High unit cost of production


Manufacturing process

Forging & Tapping process

Heating

Forging


Manufacturing process

Forging & Tapping process

Cooling

Tapping


Manufacturing process

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


Manufacturing process

Die casting process

Close the mold

Pour molten metal

Injection

Cooling


Manufacturing process

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


Manufacturing process

Injection molding process

Close the mold

Pour plastic powder

Injection

Cooling


Manufacturing process

Injection molding process

Characteristic

Advantage

- Fast, using mass production

- Stable quality

- Can make complex shape

Weakness

  • Using the specific machine

  • Die is very expensive


Manufacturing process

Wire drawing process

Sprinkle the oil

Fit through the die

Pull through the material


Manufacturing process

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
