The advantages of the hot runner system
Jan 22, 2018


1) no nozzle, no post-processing, so that the whole molding process can be fully automated, saving working hours and improving working efficiency.

2) low pressure loss.The temperature of hot runner is the same as that of injection molding machine, which avoids the condensation of the material in the runner, and the injection pressure loss is small

3)  the reuse of water mouth materials can degrade the plastic performance, while the use of heat flow channel system has no water mouth material, which can reduce the loss of raw materials and thus reduce the product cost.In the cavity, the temperature and pressure are uniform, the stress of the plastic parts is small, the density is even. Under the small injection pressure, the injection molding system is better than the general injection molding system in the shorter molding time.For transparent parts, thin pieces, large plastic parts or high demand plastic parts can show its advantages, and can produce larger products with smaller models.

4) the hot nozzle is designed in a standardized and serialized manner, with various nozzle heads available for selection and good interchangeability.The unique design and processing of electric heating ring can achieve uniform heating temperature and long service life.Hot runner system is equipped with hot runner plate and thermostat. It is designed with a variety of design, convenient and reliable quality.
