Injection molding is predominantly used in which type of processes?

Injection molding is predominantly used in processes involving thermoplastics. This manufacturing technique is especially suitable for thermoplastics due to their properties, which allow them to be melted and reshaped multiple times without significant degradation. During injection molding, these plastics are heated until they become liquid and then injected into a mold where they cool and solidify into the desired shape.

Thermoplastics are widely favored in injection molding because they can be produced efficiently in large quantities with high precision and can be easily modified for different applications. This versatility makes injection molding a popular choice in industries such as automotive, consumer goods, and electronics, where complex shapes and high volumes are often required.

While metals, ceramics, and composites are important materials in manufacturing, each typically uses different processing methods that are better suited to their unique properties. For instance, metals are often shaped using processes like casting or forging; ceramics are usually formed through pressing or extrusion; and composites are typically fabricated using techniques such as layup or resin transfer molding. Thus, injection molding is specifically aligned with the characteristics and requirements of thermoplastics.
