Hot runner, also known as runnerless system, consists of three main components: hot nozzle, manifold, and temperature control box. It is an advanced and sophisticated gating method in the field of injection molding. In the process of injection molding, hot runner plays a pivotal role. So, what are the significant advantages of hot runner? Let's delve into it together.

Firstly, it saves manpower and raw materials, effectively reducing costs.

In the injection molding process, since the melt in the gating system remains in a molten state, there is no need for processes such as gate cutting, thereby significantly saving manpower and material consumption, bringing tangible economic benefits to enterprises.

Secondly, the molding cycle is greatly shortened, and production efficiency is significantly improved.

Hot runner molds eliminate the limitation of cooling time in traditional gating systems. Once the molded part solidifies, it can be ejected immediately, greatly improving production efficiency. Many thin-walled parts produced using hot runner molds have a molding cycle of around 5 seconds, fully demonstrating the excellent performance of hot runners in enhancing production efficiency.

Furthermore, the quality of plastic products is significantly improved.

Plastic products injected and molded through hot runner molds are finished products directly, effectively avoiding common defects such as shrinkage marks caused by insufficient material feed, thereby significantly enhancing the overall quality and aesthetic appearance of the products.

Lastly, it has a wide molding temperature range and can achieve rapid molding at low temperatures.

For raw materials with poor fluidity at low temperatures, the use of hot runners can significantly improve their fluidity. Even at low temperatures, it can ensure that plastic raw materials are molded quickly and smoothly, thereby guaranteeing the smooth progress of injection molding production and the stability of product quality.

In summary, the application of hot runners in injection molding not only greatly improves production efficiency, reduces costs, but also significantly enhances the quality of plastic products and the adaptability of the molding temperature range, while also helping to extend the service life of the mold. It can be said that hot runners have become an indispensable part of modern injection molding technology.
