Type of Injection Molding

2017-11-29

hot runner injection moldPlastic injection molding parts is widely used in many industries, how to make high quality injection molding? So plastic injection mold type is very important for injection moulding production, there are two main types of injection molds - cold runner and hot runner. A runner is the channel in the mold that conveys the plastic from the barrel of the injection molding machine to the part. In a cold runner mold, the runner is cooled and ejected with the part.

 

Cold runner molding system is the most type for injection mold making. 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 re-cycled and reground, reducing plastic waste. However, these processes can increase cycle time.
