Hot runner injection molding is an advanced plastic processing technology. By maintaining the molten state of the plastic in the runner and directly injecting it into the mold cavity, it eliminates the waste generated by the traditional cold runner. The specific operation process can be divided into four stages: preparation work, startup and debugging, production monitoring, and final processing. The following is a detailed introduction

The hot runner molding process used in injection molds has significant advantages, which are mainly reflected in material conservation, efficiency improvement, quality optimization and production flexibility, etc. The following is a detailed analysis: 1. Material conservation: 1. No cold runner waste. 2. In traditional cold runner injection molding, the plastic inside the runner cools and solidifies to form waste, which requires additional treatment or recycling.

In the new year, everything we ask for is what we wish for, and everything we do is smooth. 2025- Have lots of joy, Chang'an Ning, good new year, and good old year. Wishing everyone a happy new year

Needle valve hot nozzle is widely used in injection molding machines, extruders and other plastic processing industry, mainly used to control the heating and flow of plastic raw materials, so as to control the quality and production efficiency of plastic products in the mold

The hot runner system is generally composed of several parts, such as a hot nozzle, a shunt plate, a temperature control box and accessories. Hot nozzles generally include two types: open hot nozzles and needle valve hot nozzles. Because the form of hot nozzle directly determines the selection of hot runner system and the manufacture of mold, the hot runner system is often divided into open hot runner

A hot runner system is a component of a hot runner system used to control and regulate the flow and heating of liquids. It is usually composed of needle valves, heaters, sensors and other components, which can adjust the temperature of the heater through the control system
