What is injection molding

 Injection molding is a manufacturing process used for high-volume production of parts. It is most commonly used in mass production processes where the same parts are created thousands or even millions of times in a row.

Why you may want to use injection molding

The main advantage of injection molding is its ability to be produced on a large scale. Once the initial cost is paid, the price per unit in the injection molding manufacturing process is extremely low. As more parts are produced, the price tends to drop dramatically. Other advantages include.

Low scrap rates for injection molding

Injection molding produces lower scrap rates than traditional manufacturing processes such as CNC machining, which cuts away most of the original plastic block or sheet. However, this can be a negative compared to additive manufacturing processes such as 3D printing, which have much lower scrap rates.

 

Injection molding utilizes repeatability and consistency

Injection molding is very repeatable. That is, the second part you produce will be nearly identical to the first part, etc. This is a good feature to look for when trying to produce brand consistency and part reliability in high volume production.
