1. Shorten the injection cycle: because the hot runner does not have the limitation for the cooling time of the gating system, the product can be ejected directly after the product solid, so the injection cycle will be shorter than a cold runner. Many thin thickness parts can be injected within 5 seconds by a hot runner;
2. Saving plastic material: Since there is no cold runner in hot runner mold, there is no waste or very few runners during production, especially for expensive materials and large-volume projects, it can save cost a lot.
