21. Types of injection molds
There are two main types of injection molds : cold runner (two plate and three plate designs) and hot runner - the more common of the runnerless molds . The significant difference is that the presence of a sprue and runner with every molded part in the cold runner type. This extra molded component must be separated from the desired molded part.
