Everything You Need To Know About Injection Molding

Injection Molding is a manufacturing process for producing parts in large volume. It is most typically used in mass-production processes where the same part is being created thousands or even millions of times in succession. Why Use Injection Molding: The principal advantage of injection molding is the ability to scale production en masse.

Revisiting Shot Size vs. Barrel Capacity | Plastics Technology

Jan 01, 2020 · Use 25% to 65% of the barrel capacity for your shot size. Less than 25% will unlikely yield a uniform melt. Most would agree that for a shot size less than 25% of the maximum barrel capacity, the concern is residence time. While that is an issue, I have also found that the melt quality is often poor.
