What is the purpose of injection moulding?

The purpose of injection molding is to produce complex and intricate plastic parts in large volumes with a high degree of precision and repeatability. This manufacturing method is widely used due to its ability to create parts with detailed features and complex geometries that would be difficult or impossible to achieve with other methods.

Here are some key reasons or purposes for using injection molding:

1. Mass Production: Injection molding is particularly effective for mass production. Once an initial investment has been made on a mold, the cost per unit during injection molded manufacturing is extremely low, making it a cost-efficient method for producing large quantities.

2. Complex Part Designs: This method allows for the production of intricate parts. Multi-part assemblies can often be redesigned as a single mold, reducing the need for additional joining or assembly processes.

3. High Precision and Repeatability: Injection molding is excellent for producing high-precision parts with tight tolerances repetitively. The nature of the process ensures that the same part will be produced over and over again, with negligible deviations.

4. Wide Material Selection: A vast range of materials can be used with injection molding, including various types of plastic, metals, elastomers, and more, allowing for great product customization.

5. Efficient Material Use: Injection molding typically has a very high production rate, and scrap rates are low because the excess plastic can often be recycled and reused, reducing waste.

In industries from automotive to medical, consumer products to electronics, injection molding plays a critical role in manufacturing parts and products that shape our daily lives.
