HEATERS
Compact heating elements manufactured to provide controlled, dependable heat around injection moulding nozzles and other cylindrical process components.
Compact, concentrated heating
HEAT WHERE THE
PROCESS NEEDS IT
Nozzle heaters are designed to fit closely around a cylindrical component, concentrating heat within a relatively small area.
They are commonly used on injection moulding machinery to maintain the required temperature around the machine nozzle and help keep the processed material in the correct condition.
Hotset UK can manufacture nozzle heaters around the dimensions, voltage, power, termination and installation requirements of the application.
Replacement heater?
If the original specification is unavailable, send us the dimensions, photographs, machine details, drawing or an existing sample. We can use this information to help identify a suitable replacement.
Why nozzle heaters?
DESIGNED FOR THE APPLICATION
The correct construction depends upon operating temperature, available space, watt density, fit and the surrounding process.
Close-fitting heat
Manufactured to fit around the nozzle, supporting effective heat transfer when correctly installed and clamped.
Bespoke dimensions
Diameter, width and construction can be selected around the available space and the heated component.
Electrical options
Voltage, power, lead arrangement and connection style can be specified to suit the machine and control system.
Temperature sensing
Suitable arrangements can incorporate or accommodate a thermocouple where temperature feedback is required.
Replacement manufacture
Existing heaters, drawings and application details can be used to help produce replacement products.
Typical applications
WHERE THEY ARE USED
Always confirm the heater construction against the actual temperature, environment and mechanical installation.
Injection moulding nozzles
Maintaining process temperature around the machine nozzle.
Hot-runner systems
Localised heating around nozzles and associated moulding components.
Plastics processing
Heating small cylindrical areas within extrusion and moulding equipment.
Special-purpose machinery
Bespoke cylindrical heating requirements in industrial equipment.
Preparing an enquiry
WHAT DO WE
NEED TO KNOW?
The more information supplied, the easier it is to assess the heater and provide an accurate quotation.
Technical consideration
FIT IS CRITICAL
A band or nozzle heater relies upon effective contact with the surface it is heating. An incorrect diameter, damaged surface, poor clamping or contamination between the heater and nozzle can create localised overheating and shorten heater life.
