IZOFLEX red coolant hose
In injection molding processes, precision and quality manufacturing are essential. Achieving these requires efficient cooling, for which cooling systems – and particularly coolant hoses -play a critical role. These hoses must be flexible yet resistant to high temperatures, especially in chemical industry applications. In this article, we discuss how Izoflex coolant hoses contribute to the flawless operation of injection molding machines.

Challenges and Material Quality of Coolant Hoses

The challenges associated with the use of coolant hoses are diverse. Internally, these hoses are made of black EPDM, a type of synthetic rubber that is highly resistant to heat and various physical impacts. The outer layer, which can be colored blue or red, is not only aesthetically important but also indicates the nature of the application. This labeling contributes to the safe operation of facilities. A mesh textile layer serves as an intermediate coating, enhancing the integrity and pressure resistance of the hoses. Since coolant hoses are often used outdoors, they must withstand UV radiation, ozone, and various weather conditions without losing their flexibility and durability.

Application of Coolant Hoses in Injection Molding Plants

One of the most common applications of coolant hoses is in injection molding plants, where they actively contribute to the proper functioning of the machines. The coolant hoses needed for the cooling of equipment used in injection molding must withstand extreme temperatures, considering the high-temperature liquids generated by the machines. Izoflex coolant hoses meet these requirements, maintaining their integrity even when transmitting materials at temperatures up to +140 degrees Celsius, thereby ensuring continuous and efficient cooling of injection molding machines.

Thanks to their excellent properties, these hoses are not only popular in injection molding plants but also in various other industrial areas where the transmission of hot and cold liquids is necessary. They are often used in the automotive industry or around air conditioning systems.

Wide Range of Coolant Hoses Available from Izoflex

Our range includes coolant hoses with two types of outer coatings, blue or red, which help identify their application. Izoflex hoses are resistant from -20 degrees to +140 degrees Celsius, while excelling in flexibility, pressure resistance, and longevity. The combination of EPDM inner material and outer mesh textile layer ensures high resistance to various environmental and mechanical impacts. Additionally, their ozone and UV resistance enable safe outdoor use. Our hoses reliably function in injection molding plants and other industrial applications. You can choose from various external and internal sizes, and they can also be ordered pre-fitted depending on the nature of the application.
