There are two kinds of hot runner systems: single point hot gate and multi-point hot runner system.

Single point hot gate is to use a single hot runner sleeve to directly inject molten plastic into the mold cavity, which is more suitable for the plastic mold with single cavity and single gate; the multi-point hot gate is to branch the molten material into each heat distribution gate sleeve through the hot runner plate, and then enter into the cavity. It is more suitable for single cavity multi-point feeding or multi cavity mold, and the advantages of hot runner system of dual color plastic mold are as follows: 1

The reuse of nozzle material will degrade the properties of plastic, but the use of hot runner system without nozzle material can reduce the loss of raw materials and reduce the cost of products. Companies that are doing better now

In the mold cavity, the temperature and pressure are uniform, the stress of plastic parts is small, and the density is uniform. Under the small pressure and short molding time, the injection molding can produce better products than the general injection molding system.

No water mouth material, no need for post-processing, so that the entire molding process is fully automated, save working time and improve work efficiency.

The hot nozzle adopts standardized series design, equipped with various nozzle heads for selection, and has good interchangeability.

The electric heating ring with unique design and processing can achieve uniform heating temperature and long service life.

The hot runner system is equipped with hot runner plate temperature controller, which is exquisite in design, various in variety, convenient in use and stable in quality.

The pressure loss is small.

The temperature of hot runner is equal to that of nozzle of injection molding machine, so as to facilitate the mass production of products

Mold industry is undergoing a new round of industrial adjustment, in recent years, foreign investment in China's mold industry increased, industrial developed countries_ China's mold industry is facing a new round of opportunities and challenges.
