There are three types of hot runners, namely splitter plates, nozzles, and temperature control boxes. Can you take a look at the drawings I have placed? The main gate is fed through the splitter plate and flows through the nozzle. The temperature control box, Arnoli, is temperature controlled. A hot runner mold is a mold that uses heating equipment to ensure that the melt in the runner remains non condensing. Because it has a shorter forming cycle than traditional molds and saves more raw materials, hot runner molds are widely used in various industrialized countries and regions around the world today.

Hot runner concept

The hot runner system is divided into fully hot runner and semi hot runner systems. The planning of the adiabatic flow channel is messy, but its function is good and the maintenance cost is very low. The structure of the micro semi hot runner is simplified, stable and easy to use, with a low failure rate. Due to its simple structure, the maintenance cost is low, which greatly ensures the stability of the production.

Hot runner classification

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

The hot runner system is generally composed of several parts, including a hot nozzle, a splitter plate, a temperature control box, and accessories. There are generally two types of thermal nozzles: open type and needle valve type. Because the hot nozzle method directly determines the selection of hot runner system and mold manufacturing, the hot runner system is often divided into open hot runner system and needle valve hot runner system accordingly. The splitter plate is used when the the first mock examination has multiple cavities or many points of feeding, and single point feeding, but the material level is offset.

The data generally adopts P20 or H13. The splitter plate is generally divided into two categories: standard and non-standard, and its structural method is primarily determined by the distribution of the cavity on the mold, nozzle arrangement, and gate orientation. The temperature control box includes the host, cables, connectors, and wiring male and female sockets. Mold expert WeChat editor hot runner accessories generally include heaters and thermocouples, runner sealing rings, connectors, and junction boxes.
