Advantages of Hot Runner Systems

2022-07-12


1. No water mouth material, no post-processing is required, the entire molding process is fully automated, working time is saved and work efficiency is improved.


2. Pressure loss is less. The temperature of the hot runner is equal to the temperature of the injection nozzle of the injection molding machine, which avoids the condensation of the raw material on the surface of the runner, and the injection pressure loss is less.


3. The repeated use of runner materials will degrade the performance of plastics, and the use of hot runner systems without runner materials can reduce the loss of raw materials, thereby reducing product costs. The temperature and pressure in the cavity are uniform, the stress of the plastic part is small, and the density is uniform. Under the smaller injection pressure and the shorter molding time, the injection molding system can produce better products than the general injection molding 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, equipped with various optional nozzle heads, and has 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, easy to use, and stable and reliable quality.
