Integral hot runner is an advanced hot runner system in injection molding, which integrates all components of the hot runner system in the mold design and manufacturing, and has the advantages of simplifying the structure, improving production efficiency and optimizing product quality. This paper will introduce the application of integral hot runner in injection molding and its advantages.

Integral hot runner system is a design scheme that integrates the hot runner system into the mold. The traditional hot runner system is usually composed of hot runner plate, hot runner tube and hot runner control system, and the integral hot runner system integrates these components directly into the mold to form an integrated structure. This integrated design not only reduces the number of components of the hot runner system, simplifies the structure, but also improves the reliability and stability of the hot runner system.

Integral hot runner has a wide range of applications in injection molding. First of all, it can be applied to the production of various injection molding products, such as plastic parts, molds and optical components. Whether producing large parts or small parts, the integral hot runner provides a uniform hot runner temperature distribution, avoiding the impact of temperature differences in the hot runner system on product quality.

Second, the integral hot runner is suitable for different types of injection molding materials. Whether it is ordinary plastics, engineering plastics or high temperature plastics, the integral hot runner provides appropriate hot runner temperature control to ensure the melting and flow properties of plastic materials during injection molding, resulting in high-quality molded products.

The integral hot runner system has several advantages in injection molding. First of all, due to its integrated design, the integral hot runner system has a more compact structure, reducing the volume and weight of the hot runner system, and improving the rigidity and stability of the mold. This helps to reduce mold deformation and vibration and improve the accuracy and stability of injection molding.

Second, the integral hot runner system allows for more precise temperature control. Because the components of the hot runner system are directly integrated into the mold, the conduction and control of hot runner temperature are more accurate and stable. This helps to reduce temperature fluctuations and deviations in hot runner systems, improve injection molding consistency and repeatability, and reduce scrap rates.

In addition, the integrated hot runner system has a faster heat balance speed and a shorter production cycle. Due to the compact structure of the integrated hot runner system, the heat transfer is faster and the heat balance time is shorter. This makes the cycle time of injection molding shorter and the production efficiency greatly improved.

In summary, the integral hot runner has a wide range of applications in injection molding, and brings many advantages. It simplifies the structure of hot runner system and improves the reliability and stability of hot runner system. Suitable for various injection molding materials and products; More precise temperature control and faster heat balance speed are achieved, improving the accuracy, stability and production efficiency of injection molding. The integral hot runner system is an important development direction of the injection molding industry, which will bring more innovation and progress to injection molding.
