- (1) No nozzle material, no post-processing is required, so that the entire molding process is fully automated, saving working time and improving work efficiency.
- (2) Low pressure loss. The temperature of the hot runner is equal to the temperature of the injection nozzle of the injection molding machine, which avoids the surface condensation of raw materials in the runner and the injection pressure loss is small.
- (3) The repeated use of nozzle materials will degrade the performance of plastics, and the use of hot runner system without nozzle materials can reduce the loss of raw materials and thus reduce product costs. In the cavity, the temperature and pressure are uniform, the stress of the plastic part is small, and the density is uniform. Under a lower injection pressure and a shorter molding time, a better product is injected than the general injection system. For transparent parts, thin parts, large plastic parts or high-demand plastic parts, it can show its advantages, and it can produce larger products with smaller models.
- (4) The hot nozzle adopts standardized and serialized design, and is equipped with various nozzle heads for selection, with good interchangeability. The uniquely designed and processed electric heating ring can achieve uniform heating temperature and long service life. The hot runner system is equipped with hot runner plates, thermostats, etc., with exquisite design, various types, convenient use, stable and reliable quality.
