Durex International's cast aluminum heaters have become a benchmark in the extrusion industry due to their exceptional performance, durability, and versatility. These heaters are designed to meet the precise heating needs of extruders, ensuring efficient and consistent operation. In this article, we will delve into the features and benefits that make Durex International's cast aluminum heaters stand out as the best choice for extruders.
Introduction to Cast Aluminum Heaters
Cast aluminum heaters are renowned for their excellent heat transfer efficiency, durability, and energy efficiency. These characteristics make them ideal for applications requiring precise temperature control, such as plastics extrusion. The cast aluminum construction allows for uniform heat distribution, ensuring that the extruder operates at optimal temperatures.
Advantages of Cast Aluminum Heaters
1. Exceptional Heat Transfer Efficiency: Cast aluminum is an excellent conductor of heat, allowing for rapid and even heat distribution across the extruder barrel. This efficiency reduces energy consumption and enhances heating performance, which is crucial in maintaining consistent melt temperatures during extrusion processes.
2. Durability and Longevity: Cast aluminum heaters are highly resistant to corrosion and oxidation, making them suitable for both indoor and outdoor use. Their robust construction withstands harsh environmental conditions, reducing maintenance costs and extending their lifespan.
3. Versatility in Design: These heaters can be customized to fit specific extruder designs, ensuring precise temperature control and adaptability to various extrusion applications.
4. Energy Efficiency: By heating up quickly and distributing heat evenly, cast aluminum heaters offer significant energy savings over time, making them a cost-effective solution for extrusion processes.
Durex International's Cast Aluminum Heaters for Extruders

Cooling Systems for Extruders
Durex International's cast aluminum heaters often incorporate advanced cooling systems to maintain precise temperature control during extrusion processes.
Liquid Cooled Cast-In Barrel Heaters
Liquid cooled cast-in barrel heaters are the most common design used in plastics extrusion. These heaters feature liquid cooling tubes that run symmetrical to the heater element, providing a uniform cooling pattern across the casting. This design allows for rapid heat dissipation from the barrel, enabling tight control over melt temperatures during operation.
Air Cooled Cast-In Barrel Heaters
Finned air-cooled designs provide effective heating and cooling for plastics extrusion barrels. The fin pattern can be supplied as a standard height of 1” or manufactured to a low profile thickness for small extruders or applications requiring rapid cooling. This pattern is designed to allow the optimal airflow around the casting for maximum cooling rates. Typically, the forced air for the cooling function is driven by a shroud and blower system that is an integral part of the extruder, however these heaters can be utilized with an individual shroud and blower assembly for increased cooling control of the individual heater zones.
Vent Cutout Cast-In Heaters
Special sections of the cast-in extruder barrel, such as vents or feed throats, require custom modifications to fit properly. These Vent/Cutout Cast-In Heaters are designed with element locations that maximize heater performance while allowing for special machined sections that could not be added to a standard barrel design.
Applications of Cast Aluminum Heaters in Extrusion
Cast aluminum heaters are versatile and can be applied in various extrusion processes, including:
- Plastics Processing: These heaters are widely used in plastics extrusion for their ability to maintain precise temperature control, which is crucial for producing high-quality plastic products.
- Foodservice Equipment: Cast aluminum heaters are also used in foodservice equipment due to their durability and ability to withstand high temperatures.
- Medical Equipment: In medical applications, these heaters provide precise temperature control, which is essential for maintaining sterility and efficiency.
