What does hot runner mean?

Hot runner is a common heat flow control system in injection molding. By heating and controlling the heat flow in the mold, thermoplastic materials can flow into the mold smoothly for molding. The hot runner system consists of a hot runner controller, a temperature controller, a heating device, a heat pipe and a heat conducting plate. It can greatly improve the production efficiency and finished product quality, and save the cost of raw materials and human resources.

The advantages of hot runner system are mainly reflected in the following aspects: first, it can reduce the cooling time of products, thus improving production efficiency; Secondly, the hot runner can reduce the defects in injection molding, such as short shot, bubble and burr, so as to improve the quality of finished products. In addition, the excellent performance of the hot runner system can also reduce the wear degree of the mold and prolong the service life of the mold.

Hot runner system is widely used in injection molding, covering many industries, such as automobile parts, household appliances, medical devices and so on. With the continuous progress of science and technology and the improvement of people's requirements for the quality of finished products, hot runner technology is also developing and improving. In the future, the hot runner system will be more intelligent and automatic, which will bring more convenient solutions to the production of different industries.
