6:节能:此种镶嵌式发热丝铜套的接触面积为65%(弹簧发热圈的有效接触面25—33%),接触面大导热面积就大,铜套和热咀的接触紧密,导热速度快。热损耗很少,节省电能。
10:维护试模方便 根据不同尺寸的铜套有专用制具安装和拉拔制具.
Fit tight: the heater diameter is less than the hot nozzle outside diameter, the negative tolerance, the use of copper pipe itself tension clamp hot nozzle, no gap, fit tight.
2: rapid heating: reactive power consumption, high power heating wire. The test: to be heated object in the same, the 370W copper ring heating and 600W spring heating test, at the same time reached 300 degrees at the same temperature.
3: small volume: use heating wire = thickness of the wall of small diameter, wall thickness of 2.0 to 3.0, day of small mold frame opening space, the relative increase in the strength of the mold, reduce the mold processing of cutting quantity, reduce tool wear.
4: maintenance is convenient, save time and effort: opening = easy to install and remove. Only one clamp spring clamp can be easily installed and disassembled.
5: long life: embedded wire contact area, fast heat conduction, heating wire generate fast heat conduction, high temperature does not occur, reduces the load of a resistance wire, pipe loop, no resistance wire are overlapped, there is no resistance wire in the tube short circuit trouble.
6: Energy: this mosaic hair copper wire sleeve contact area was 65% (spring heating ring effective contact surface 25 - 33%), contact area of high thermal conductivity is high, copper sleeve and a hot nozzle close contact and conduction speed fast. Very little heat loss, saving energy.
7: to improve the efficiency of injection molding: fit tight, fast heat transfer, short heating time, shorten the cycle of injection molding.
8: to improve the quality of the injection parts: uniform heat conduction to the hot nozzle will not produce local high temperature or low temperature, the plastic material will not be due to uneven temperature and high temperature decomposition or melt melting, can improve the quality of injection molding parts.
9: heating uniform copper four axis machining, can be based on different hot nozzle structure, material properties to arbitrary distribution of heating section.
10: the maintenance of the test mode is convenient according to the different sizes of copper sets have a special system installation and drawing tools.
