Cast Aluminium & Bronze Heaters

We manufacture a wide range of high-quality aluminium bronze cast heaters, designed to deliver superior results in heat distribution and efficiency.

The excellent thermal conductivity of our aluminium bronze cast heaters ensures a highly uniform temperature across component surfaces, effectively eliminating hot or cold spots that could negatively impact equipment performance.

Our cast heaters feature a tubular sheathed wire element, renowned for its reliability, strength, and versatility. This adaptable element allows our aluminium bronze cast heaters to be tailored to meet a broad range of applications and specifications. Every heater is designed and manufactured in-house—from the design and construction of the tubular heating element and element forming, to machining and electrical connections. With full control over the entire manufacturing process, we ensure our cast heaters meet the highest performance standards.

With extensive experience in designing and producing aluminium bronze cast heaters, supported by continuous research and development, we are well-equipped to assist you. Our qualified design engineers are available to discuss your specific requirements and applications for our aluminium bronze cast heaters and provide expert advice tailored to your needs.

Advantages

High Thermal Conductivity
Our cast heaters provide exceptionally uniform temperatures across the entire heated surface, ensuring consistent heat distribution.

Accurate Temperature Control
The high thermal conductivity of our heaters effectively eliminates hot or cold spots that may arise with other heating methods, allowing for precise temperature control.

Exceptional Durability
Built with a reliable tubular sheath wire element and ribbed construction, our cast heaters are designed to withstand misuse, offering long-lasting performance.

Efficiency
The superior thermal conductivity of our heaters rapidly transfers heat from the tubular element to the component surface, maximizing efficiency.

Contamination Resistance
With the heating element securely cast into the aluminium and sealed terminal boxes, our cast heaters are highly resistant to contaminants, ensuring reliable and clean operation.

Cast Aluminium Finned Heaters

Forced air cooling of extruder barrels using finned heaters has demonstrated proven effectiveness in the field over many years. Recent advancements in casting techniques have expanded fin surface area, while improvements in blower efficiency and output have made air cooling a viable alternative to water cooling for many applications. The key advantages of air cooling include its cleanliness, efficiency, affordability, and ease of maintenance.

Our finned heaters are cast in halves, bolted together, and machined in pairs to ensure a precise fit on extruder barrels. They can be supplied with close-fitting air cowls to enhance efficiency, as well as insulation to minimize heat loss and lower ambient outer casing temperatures. They can also be fitted with inlet and outlet air deflecting boxes, along with fan mounting attachment plates.

With high-output blowers (single or double outlet) attached to the inlet box, we are capable of providing a complete heating and cooling system.

Furthermore, we specialize in converting existing systems from water cooling to air cooling, offering tailored solutions for your specific needs.

Cast Aluminium / Bronze Heaters / Coolers

Liquid cooling has been a widely used and highly efficient method in plastic extrusion for many years. Aluminium/Bronze heater coolers are now considered standard in the plastics processing industry, replacing costly machine-grooved barrels.

Our heater coolers are cast in halves, strapped or bolted together, and machined in pairs to ensure a precise fit on extruder barrels. They are available with either single or double cooling tubes, which can be cut to length and pre-formed to accommodate extruder obstacles, or factory-fitted with various pipe fittings.

Standard cast-in connectors are available for easy connection, offering additional protection during storage and transit.

The design and layout of the cooling tube are critical, as continuous heating and cooling cycles generate internal thermal stresses. Incorrectly designed cooling tubes may lead to premature failure, which is why we ensure our systems are optimized for longevity and reliable performance.

At Elmatic, we are dedicated to providing bespoke heating solutions that deliver superior performance, reliability, and durability, tailored to meet the unique needs of each of our clients.
