What is a Hot Runner System and Why Does it Matter in Moulding

A hot runner is a system used in plastic injection moulding. The system keeps the plastic in a heated condition as it moves through the mould. This means the plastic stays molten until it reaches the cavity. A cold runner lets the material cool inside channels. A hot runner keeps it flowing. Hot Runner and Control Systems Hot Runner and Control Systems are built to keep the temperature steady. This is important for parts that must look clean with no marks. When the temperature is off, the product may show defects. Good systems keep every cavity filled with balance. This gives uniform results. Why Hot Runner Controllers Matter Hot Runner Controllers make sure each zone is managed well. The operator sets the temperature for each area. If one part gets too hot it may burn. If it gets too cold it may freeze. With Hot Runner Controllers the mould stays stable during the cycle.
