The overall hot runner system is a plastic processing technology characterized by using heating elements to maintain the plastic melt in a flowing state at all times, achieving full heating of the mold runners and gate areas.

The advantages of the overall hot runner system are as follows:

The casting system is shortened: The overall hot runner system ensures uniform flow of plastic melt within the mold, thereby reducing the length of the casting system, enhancing the transmission effect of injection pressure, and stabilizing the product forming process.

By avoiding cold runner: The overall hot runner system ensures that the plastic melt maintains a high temperature throughout the filling process, effectively preventing the formation of cold runner and enhancing product quality.

Reducing Waste Rates: The uniform heating effect of the overall hot runner system can reduce internal stress and shrinkage in products, thereby lowering waste rates and enhancing production efficiency.

Energy-saving and environmental protection: The overall hot runner system reduces cooling time and water consumption, thereby lowering energy consumption and production costs. Additionally, by reducing the rate of defective products, it also diminishes plastic waste, making it more environmentally friendly.

However, the overall hot runner system does have some drawbacks:

Higher Costs: The overall equipment cost of the hot runner system is high, which may be unaffordable for some small businesses.

High Technical Requirements: The heating elements of the overall hot runner system require precise temperature and heating time control, demanding a higher skill level from the operators.

High maintenance costs: The heating and control components of the overall hot runner system require regular maintenance and replacement, which increases maintenance costs.
