Coil Heaters are made of coiled cable heater.
Coil Heater is a special tubular heater which has small diameter and high performance.
Generally, there are three kind of cross-sections for this heater: rectangular, square and round.
Commonly, the heaters are fully annealed and they can accommodate J-type and K-type thermocouple. The sensors can be installed internally at the end or the middle of a coil heater.
The heating core is solid nickel chrome wire (or others) and the sheath material for coil heater is stainless 304 (or custom)
The heating core is sealed from contamination and the stainless steel is corrosion-resistant. Due to the unique construction, they are robust and low maintenance cost.
It can provide very high watt density up to 40W/in2 and can attain a surface temperature up to 1500 F.
It is the ideal heater to concentrate a large amount of heat into very limited space.
Hot runner spring heating ring heater, heating wire cross-section 2.2*4.2, 3.0*3.0, 3.5*3.5, round 1.6, 1.8, 2.0, 2.2
Etc. According to customer requirements
Spring ring shell material: 800 material: high temperature oxidation resistance
The resistance wire adopts the resistance wire imported from Sweden. The appearance of the outer sleeve is clean and the temperature is high. The wire is pure nickel wire.
The heating wire molding method is rotary satin compression, magnesium powder is imported from Japan, and the high density combination is unique to all parties.
Four lines without overlap, high winding yield, durable, uniform heating
Insulation above 500 MΩ, positive and negative resistance 1%
