1, shorten the forming cycle of the parts because there is no limitation of the cooling time of the runner system, the parts can be ejecting in time after forming and curing. Many thin-wall parts produced with hot runner molds can be formed in less than 5 seconds in a pure hot runner mold because there is no cold runner, so there is no production cost. This is particularly significant

Integral hot runner is an advanced hot runner system in injection molding, which integrates all components of the hot runner system in the mold design and manufacturing, and has the advantages of simplifying the structure, improving production efficiency and optimizing product quality. This paper will introduce the application

Hot runner An important step is the design concept of hot runner. A detailed design concept, including manifold and platen, will be an important part of the mold audit.The manifold is used to ensure that the liquid channel is arranged in the most efficient manner

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
