Handheld Vacuum Disassembling

Bill of Materials

 Vacuum Handheld

 Vacuum nose suction

• Injection Molding
• cheap easy to manufacture

Cable 

• cheap and can be reused
• Machined
• To protect the wire

 Switch

• cheap and easy to produce
• Injection Molding

-

 Switch Cover

• cheap and easy to produce
• injection molding

Lock Spring

• Elasticity of material
• Die casting

 Screws

• Molding
• cheap and strength

Impeller blades

• Machined
• increase the pressure of air which turn moves them against the resistance caused by dust

 Left Motor Casing

• cheap
• Injection Molding

 Right Motor Casing

• cheap
• Injection Molding

Dust bag

• Injection Molding
• Collect dust 

AC Motor

• Machined
• Less expenses
