High Temperature Resistance Sealed Nozzle Hot Runner Coil Heater
- PRODUCT DETAIL
Hot runner heater is an advance concept of thermal engineering which has a construction similar to high watt density cartridge heaters,our production length in 400-3000mm is mainly used for hot runner mold ,as well as other precision heating system.Spring heating ring external using high quality Ni-Cr steel tube,it has glass fiber package which can prevent leakage,the external use of high purity magnesium oxide, high temperture resistance wire, and first-class manufacturing technology.These Heaters can be constructed with or without built in thermocouples. Its high working temperature ,fast heating,uniform heating precision,long service life,can be automatically controlled area,high thermal conduction,while internal heating material damage,external can reuse.
