Explain the differences between injection molding, blow molding, and compression molding

Question

Accepted Answer

Injection molding, blow molding, and compression molding are three different manufacturing processes used to create plastic parts.

Injection molding involves injecting molten material into a mold cavity, which then cools and solidifies to form the desired shape.
Blow molding is used to create hollow objects by inflating a heated plastic tube inside a mold.
Compression molding involves placing a pre-measured amount of material into a heated mold cavity and then compressing it to form the final shape.
Injection molding is commonly used for mass production of small to medium-sized parts, while blow molding is often used for producing bottles and containers.
Compression molding is suitable for larger, more complex parts with lower production volumes.
