Hot half mold&multi cavity hot runner system

Hot runner system is a commonly used technology in injection molds, which can help control the flow and solidification of plastic materials during the injection molding process. It consists of a hot runner and nozzle, which maintain a constant temperature through a hot fluid (usually hot oil).

The function of the hot runner system is to maintain the molten state of plastic materials during the injection molding process by providing a constant heating temperature, and to enter the mold cavity through the runner for filling. Compared to traditional cold runner systems, hot runner systems can effectively reduce plastic material consumption, shorten injection molding cycles, and reduce product defects such as nodules and marks.

Hot runner systems can be divided into different types based on specific design structures, such as independent hot runner systems, valve hot runner systems, and series hot runner systems. Each type of hot runner system has its applicable situation and characteristics, and the most suitable hot runner system can be selected according to the requirements of injection molded products.

In summary, the hot runner system is a commonly used technology in injection molding, which maintains the flow and solidification of plastic materials by controlling the temperature of the hot fluid. It can improve the efficiency of injection molding production and the quality of products, reduce material waste, and is one of the commonly used technologies in modern injection molding processing.
