Cold runner vs. hot runner?

Molding systems Cold runner vs. hot runner Every plastic part starts in a mold. Molds are classified into two main types, cold runner and hot runner. Each has its advantages and disadvantages. Your plastic injection molder will be able to give you the costs and benefits of using these different systems. However, by understanding the key differences of these technologies, you can have a more educated discussion on the type of mold that would best fit your project. First, let’s discuss cold runner molding systems Cold runner molds usually consist of 2 or 3 plates that are held within the mold base. The plastic is injected into the mold via the sprue and fills the runners which lead to the parts in the cavity. In 2 plate molds, the runner system and parts are attached, and an ejection system is used to separate the pair from the mold. For those of you who assembled a model car at some point in your youth, the runners and the parts were not separated. The child assembling the model was responsible for that final part of the process. In 3 plate molds, the runner is contained on a separate plate, leaving the parts to be ejected alone. In both systems, the runner is recycled and reground, reducing plastic waste.
