injection Moulding
Injection Moulding 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. This manufacturing method has proven to be the most effective one.
The principal advantage of injection moulding is the ability to scale production en masse. Once the initial costs have been paid the price per unit during injection moulded manufacturing is extremely low. The price also tends to drop drastically as more parts are produced.
Injection Moulding produces low scrap rates relative to traditional manufacturing processes like machining which cut away substantial percentages of an original plastic block or sheet. This however can be a negative relative to additive manufacturing processes like 3D printing that have even lower scrap rates. Injection moulding is a great technology for finished production on a massive scale. It is also useful for finalized prototypes that are used for consumer and/or product testing. Prior to this late stage in production, however, 3D printing is much more affordable and flexible for products in the early stages of design.
