The Importance of Hot Runner Heaters

What are the Applications of Hot Runners?

• 1. Industrial Works: Hot runners are commonly used in industries such as metalworking, iron and steel, and the automotive sector. They are preferred as protective equipment for workers exposed to high temperatures.
• 2. Welding Processes: Hot runners are used to protect welders from hot metal droplets and sparks during welding processes.
• 3. Furnace and Kiln Works: Workers in furnace, kiln, and glass production industries use hot runners to protect themselves from high temperatures.
• 4. Heating and Ventilation System Works: Hot runners are used to ensure the safety of workers during the installation and maintenance of heating, ventilation, and air conditioning systems.
• 5. Foundries: Workers in foundries use hot runners to protect themselves from the heat of molten metal during metal casting processes.
• 6. Thermal Power Plants: Workers in such facilities use hot runners to increase their safety due to exposure to high temperatures.
• 7. Chemical Industry: Workers in chemical factories use hot runners to protect themselves against hazards that may arise during the processing of chemicals.

What is the Operating Principle of Hot Runners?

• The hot runner system is a technology used in plastic injection molding.
• The molten plastic is kept hot while being transferred from the injection machine to the mold.
• It prevents plastics from solidifying when entering the mold and ensures even distribution to every corner of the mold.

What are the Advantages of Hot Runners?

• Higher production speed
• Less material waste
• Higher product quality
• Less mold maintenance
• Less labor
• Less energy consumption
• Safer working environment
• More environmentally friendly
