Injection molds are tools used in the manufacturing process to create plastic parts. They work by injecting molten plastic into a mold cavity, where it cools and solidifies into the desired shape. This method is efficient for producing large quantities of identical items, making it popular in industries like automotive and consumer goods. The design of an injection mold is crucial for ensuring the quality of the final product. It typically consists of two halves, known as the mold cavity and mold core, which fit together to form the shape of the part. Proper cooling channels are also integrated to speed up the solidification process.
