If you can, try to get a hot runner system that has a lot of zones so you can control the temperature better and have more flexibility. Plastics should flow balanced in the hot runner system. The gates should be opened at the same time to allow the plastic to fill each cavity synchronously.
Improve the efficiency of the molding system – A molding process' efficiency goes up a notch with a hot runner system. The system uses a heated manifold to maintain the molten plastic's temperature, allowing for a more consistent and even flow of material. This leads to less waste, fewer defects, and a better final product.
Thermal contraction and expansion – This limitation is due to the different design options available. Some hot runner system designs don't have proper elimination of heat generated during production, which can likely lead to the expansion and contraction of the mold. This can sometimes lead to deformities in the final product.
High requirement for equipment – Hot runner systems require specialized machinery, monitoring systems, and controllers. And this equipment is typically expensive. Its availability and acquisition must also be from a trusted supplier. Increased cost – A drawback that must be considered is the cost.
Temperature regulation: The hot runner system is equipped with heaters and thermocouples that maintain the desired temperature in the runners and nozzles. The heaters keep the plastic in a molten state, while the thermocouples monitor and control the temperature accurately. Why Use Hot Runner for Injection Molding?
