Question &Ans:- Injection Molding Process - Introduction

Quest:-




What is plastic Injection molding?




Ans:-

 Plastic injection molding starts with small pellets compounded to meet certain physical properties. 

These pellets are then dried and fed into a hopper,

which allows them continuously dried and fed into the throat of the machine.

The machine them melts the plastic in a heated barrel,

and injects it under high pressure out of the barreland  into your mold cavity.

The injected plastic quickly fills the cavity,

and it is then allowed to cool while the machine fills its barrel for the next cycle.

 As the plastic cools, it changes back to a solid.

After a set amount of time, the mold opens, exposing the part, and hydraulic ejector pins push the part out of the cavity.
