Common questions on this part
Extremely critical. Cartridge heaters rely on conductive heat transfer. A reamed hole with clearance no greater than 0.1mm (0.004") is essential. Gaps larger than 0.15mm cause thermal insulating air barriers that lead to localized overheating and rapid heater burnout.
A high-temperature thermal transfer and anti-seize paste (such as boron nitride grease rated to 1000°C) is recommended. It facilitates heat transfer into the platen and ensures the heater can be easily extracted during future maintenance.
No. Avoid sharp bends within 15mm of the cartridge sheath exit to prevent internal wire breakage or shorting against the metal sheath rim.
Yes. STARNEX supplies custom cartridge heaters with built-in Type J/K thermocouples, right-angle lead exits, and armored braided leads on 2 to 5 days lead time.
Yes. We stock over 20 popular sizes of cartridge heaters at our Nairobi trade counter.
