No spout material, no post-processing is needed, the entire molding process is fully automated, saving working time and improving work efficiency.
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 the raw materials in the runner and the injection pressure loss is small.

The repeated use of nozzle materials will degrade the performance of plastics, and the use of hot runner systems 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 plastic parts have low stress and uniform density, and at a lower injection pressure and shorter molding time, the product is better than the ordinary injection molding system. For transparent parts, thin parts, large plastic parts or high-demand plastic parts, it can show its advantages, and can produce larger products with smaller models.

The thermal nozzle adopts a standardized and serialized design, and is equipped with various optional nozzle heads, which has good interchangeability. The uniquely designed and processed electric heating coil can achieve uniform heating temperature and long service life. The hot runner system is equipped with hot runner plates, temperature controllers, etc., with exquisite design, various types, convenient use, and stable and reliable quality.
