Hot runner is a cyclic injection molding process used on molds to aid in the melting of plastic. It can also control the temperature, consistency, and injection pressure of our materials, allowing technicians to adjust the machine freely and achieve the desired product. Due to the hot runner being exposed to high temperatures for a long time, it is inevitable to encounter some problems such as abnormal temperature rise and glue filling,

The advantages of hot runner molds are that hot runner molds are widely used in industrialized countries and regions around the world today. This is mainly because the hot runner mold has the following significant characteristics: 1. Shortening the forming cycle of the workpiece. Due to the lack of cooling time limitations in the runner system, the workpiece can be ejected in a timely manner after solidification.

A hot runner temperature control box, also known as a hot runner temperature controller, is a device that continuously maintains the required temperature value of the hot runner system. It is composed of a temperature control card, air switch, box, fan, wiring base, and cables.

1, the maintenance of the mold should pay attention to the original condition of the mold when disassembling the mold, so that it is convenient to recover when installing the mold later, and the thickness of the gasket should be engraved on the part and recorded. Replace the punch to test whether the discharge block and the die are smooth, and test whether the gap between the insert and the die is uniform, and replace the die to test whether the gap between the insert and the punch is uniform.

To eliminate or reduce malfunctions during use as much as possible, the following precautions should be taken when selecting and applying a hot runner system: 1. Selection of heating method Internal heating method: The internal heating nozzle has a complex structure, high cost, difficult parts replacement, and high requirements for electric heating elements. Placing the heater in the middle of the flow channel will generate annular flow,
