The two-stage heating nozzle processing technology is to heat the processed plastic particles by the injection molding machine to ensure that the plastic of the runner and the gate remains molten for injection molding. In the production of existing plastic products, the melted plastic is injected into the mold to be formed in a hot runner system consisting of a hot nozzle, a valve needle, a heater

In general, the hot runner system is divided into single-head hot runner system, multi-head hot runner system and valve gate hot runner system. The single-head hot runner system is mainly composed of a single nozzle, nozzle head, nozzle connecting plate, temperature control system, etc

The hot nozzle is used to ensure that the plastic in the runner and gate is kept molten by heating. Since the heating rod and heating ring are located near or in the center of the flow path, the entire flow path from the barrel outlet of the injection molding machine to the gate is in a high temperature state, so that the

Hot runner is to ensure that the plastic of the runner and gate is kept molten by heating. Since there is a heating rod and heating ring near or in the center of the runner, the entire runner from the nozzle of the injection molding machine to the gate is in a high temperature state, so that the plastic

The hot runner system is divided into fully hot runner and semi hot runner. The design of adiabatic runner is complicated, but the effect is good and the maintenance cost is very low. The micro semi-hot runner structure is simple, stable and easy to use, low failure rate, low maintenance cost because of the

VDT-25 hot nozzle is an efficient, energy-saving and environmentally friendly hot runner system component, which is widely used in various plastic processing industries. It is composed of heater, hot nozzle and thermocouple and other parts, made of stainless steel material, with excellent corrosion resistance, high temperature resistance
