There are three types of hot runners: splitters, nozzles, and temperature control boxes. The main gate is fed through a splitter plate and flows through a nozzle, while the temperature control box Arnoli is temperature controlled.

Hot runner injection mold is a mold that uses a heating device to keep the molten material in the runner from solidifying. Because it has a shorter forming cycle than traditional molds and is more cost-effective in terms of raw materials,

So hot runner molds are widely used in various industrialized countries and regions around the world today.

Hot runner concept

Hot runner systems are divided into adiabatic runner systems and micro semi hot runner systems. The design of adiabatic flow channels is complex, but the effect is good and the maintenance cost is very low. Micro semi heat flux

The structure of the road is simplified, stable and easy to use, with a low failure rate. Due to its simple structure, the maintenance cost is low, providing greater assurance for the stability of production.

Hot runner classification

Open type (for micro semi hot flow channels), needle valve type (for adiabatic flow channels).
