In industrial heating equipment using the steel heating showing a lead single head heating tube, called a mold heating tube, electric industry in china,
The title of model: M3; abroad as a cartridge heater. In the choice of procurement to selected according to the characteristics of the use of equipment, conventional Die single head heating tube with thread single end electric heating tube, L type single end electrothermal tube, single head heating tube and so on several styles, common types are inscribed high temperature wire type, external temperature line, a lead out rod outer the high temperature line, directly leads to the several types of stick. So choose according to the actual need by the use of the environment and equipment selection.
In the design process of the injection mould for single head heating tube, need to know is designed for one-way or two-way connection or connection of various forms, the choice of materials is also very important is seamed tube or seamless pipe or stainless steel tube, need to have a clear judgement on heating equipment.
Comprehensive analysis of mold heating tube of different models but timber and performance design are common. Die single head electric heat pipe performance requirements are as follows:
1, the heating up time. In the test voltage, components from the environment temperature to test time temperature should not exceed 15 minutes.
2, rated power deviation. In the full range of heating conditions, components of the power rating of deviation should be no more than the prescribed.
3, insulation resistance. The factory inspection of cold insulation resistance should not be less than 50000000000000 ohm.
4, the insulation strength. Components should be in under the test conditions and test voltage for 1 minutes, but no flashover and breakdown phenomena.
