BUILT-IN THERMOCOUPLES
One option of cartridge heater is built-in thermocouples. These thermocouples could be attached at the end or middle of the cartridge heater, grounded or ungrounded. Thermocouples could be type “J” or “K”.
WELL SEALED AND MOISTURE PROOFING
In order to strengthen the product's sealing and prevent from moisture, Teflon lead wires could be used. Lead end is sealed with Epoxy, silicone or Teflon. Maximum temperature could reach 245 ℃ .
MATERIALS FOR HIGH TEMPERATURE
If heaters are operating under extreme high temperature, shengfumei cartridges could be sealed by ceramic end cap with high temperature ceramic glue. Maximum temperature could reach600- 800℃ .
CUSTOM DISTRIBUTED WATTAGE
In some applications such as sealing or rubber molds, the two ends of a cartridge heater are usually colder than the middle. To solve this inconsistency and have a uniformly distributed heat source, cartridge heaters could be made to have higher wattages at the ends.
CUSTOM NON-HEATING PARTS
Non-heating parts could be customized. Non-heating part length and position could be manufactured according to the applications to achieve best effect. No heat section could be in the middle or at the end of the cartridge heater.
OPTIONAL HEATING ZONES
shengfumei provides customization of separate heating zones in a product. It could be used as normal heater, or separately control each heating zones when needed to realize partial heating
