What is a Hot Runner Nozzle?
Spiral heater nozzles, commonly known as hot runner nozzles, are widely used in injection mold machines. These nozzles, utilized in various industrial sectors according to different standards and purposes, are preferred extensively in applications ranging from automotive fuel injection systems to natural gas systems and liquefied petroleum gas usage. Their primary function is to spray chemicals and facilitate the opening and closing of the system in injection systems produced for specific purposes.
Recently, it has been observed that hot runner nozzles are being increasingly favored over cold runner systems in plastic injection molds. Among the reasons for this preference are the attainment of higher-quality products, increased production speed, and reduced labor costs.

Technical Information of Hot Runner Nozzles
The hot runner nozzle, a widely used component in the production of industrial machines, is also known as a manifold nozzle. This product, actively employed in various sectors, is an important part to enhance the performance of industrial machines.
Hot runner nozzles can be manufactured in both standard and custom dimensions. Made from stainless CrNi pipe, these heater nozzles feature a stainless outlet tube junction. Electrically operated injector nozzles possess the ability to open and close via a trigger mechanism. Additionally, they are equipped with 80/20 nickel-chromium heater wire resistant to melting temperatures up to 400°C. Hot runner nozzles, coated with thick mineral insulation of magnesium oxide, provide users with convenience through a flexible PTFE Teflon-coated thermocouple cable.
Selecting an appropriate hot runner nozzle is essential to enhance the efficiency of your industrial products. At Heater Resistor, we aim for quality and customer satisfaction in industrial heater purchases, offering our customers the highest quality hot runner nozzles.
Hot Runner Nozzle Usage Areas
Oil and Gas Industry: Hot runner heater nozzles are commonly used in oil pipelines, gas pipelines, and refinery facilities. These nozzles ensure the smooth direction of fluids and enhance the efficiency of the system.
Chemical Industry: Hot runner heater nozzles are used in chemical processes to provide different reaction conditions. They are widely used in chemical plants, especially in systems operating under high temperature or pressure.
Power Plants: In thermal power plants, hot runner heater nozzles are used to ensure steam and water flow with a specific fluidity and direction.
Food Industry: In food production, hot runner heater nozzles can be used, especially when high temperatures or viscous fluids need to be transported.
HVAC Systems: In the HVAC systems of large buildings, hot runner heater nozzles can be used to regulate and direct airflow.
Water and Wastewater Treatment Plants: In water treatment plants, hot runner heater nozzles can be used to ensure water flows in a specific direction and speed, enhancing the effectiveness of treatment processes.
Hot Runner Nozzle Technical Specifications
Material: The hot runner heater nozzle is typically made of high-quality carbon steel or alloy steel. These materials must be resistant to high temperatures and chemical abrasion.
Dimensions: The hot runner heater nozzle can vary in size, but it usually has specific diameter and length measurements. These dimensions are determined according to the requirements of a particular project or application.
Coating: Since the hot runner heater nozzle is often used for hot-dip galvanizing, it can be coated with materials such as stainless steel or specially coated steel.
Durability: Due to exposure to high temperatures and abrasive substances, the hot runner heater nozzle must be durable. This can be achieved through careful selection of steel and, when necessary, the use of special coatings.
Connection Structure: The hot runner heater nozzle is typically designed to connect with pipelines or structural steel elements. Therefore, it must have appropriate connection features, usually threaded or weldable.
Standards: The hot runner heater nozzle must comply with specific industry standards. This is important for the quality and reliability of the product and is usually determined according to ASTM, DIN, or other similar industry standards.
These technical specifications are generally typical for hot runner heater nozzles. However, depending on the requirements of a specific application or project, more specific specifications may also be determined. Therefore, it is important to verify whether the hot runner heater nozzle meets specific requirements when purchasing or designing it.
