The use of hot runners in molds abroad has reached 80-90%, while the use of hot runners in domestic molds is around 30%. The use of hot runners in molds will become increasingly common. The popularity and popularization of hot runner molds are also aimed at improving the utilization of raw materials and product quality. They are implemented together with hot runner design during mold design, which can definitely bring benefits to enterprises.

What is a hot runner system and what are the precautions for operating a hot runner system. In plastic injection molds, in order to promote the flow of plastic melt in the mold cavity, the main and branch channels are heated using appropriate methods to keep the plastic in a molten state, and the construction of continuous injection molding is called a hot runner system. The advantages and disadvantages of a hot runner system include saving raw materials, reducing injection molding cycles, improving production efficiency, 100% productization of raw materials, reducing defects caused by secondary materials, and improving product quality (pressure, reduced internal stress of the product). Prolonging mold life does not require reserving runner positions, reducing mold size. It is easy to set gate positions. The disadvantages of mold cost increase, maintenance and warranty require professional mold design to be fully inspected.

Compared with ordinary runner molds, hot runner molds have significant advantages such as time-saving and material saving, high efficiency, and stable quality. However, at one point, their widespread application was hindered by the tendency to cause malfunctions in use. With the technological progress of the mold industry, hot runner molding has made significant progress in controlling the melt temperature of the runner, ensuring structural reliability, and designing and manufacturing hot runner components. This has led to the re recognition and favor of hot runner technology.

Precautions for using temperature controllers:

1. The main power supply, single point, two point, and four point controller power supply is 240V single-phase three wire type

There are two types of total power supply for the six point controller: 240V single-phase three wire and three-phase four wire

The power supply of the eight point controller is 240V three-phase four wire type

The power supply of the twelve point controller is 240V three-phase four wire type

2. Please carefully follow the following instructions for the wiring method

3. After wiring is completed, please use an electricity meter to check for short circuits or reversed connections

4. Please keep this temperature controller away from high temperatures and avoid heavy pressure
