Injection molding is a manufacturing process used to produce parts and products by injecting molten material, usually plastic, into a mold or cavity under high pressure. This leads to the melting of the material, which is then injected into the mold, where it is cooled and solidified, taking on the shape of the mold. Injection molding is a versatile process that can be used to produce complex shapes and parts with high precision and accuracy, making it a popular choice in a wide range of industries, including automotive, medical, packaging, and consumer goods.
