電熱管-模具加熱棒-電加熱器

模具用單頭電熱管本身為高瓦特密度,經常因為熱傳遞太差,造成外部管體焦黑,內部高溫加速電熱線老化,導致電熱線斷裂;模具深孔加工應注意孔徑和長度的精準度,不可兩頭鉆孔,因為交接處無法密合而有較大孔隙,使電熱管散熱不良,被加熱體溫度不平均;電熱管安裝時應把加熱區域全部放入模具孔里,并加以固定,保護發熱區不外漏空燒;避免使用耐溫低的熱傳導泥,以免造成內孔積碳、漏電,日后不易更換電熱管。

One of the reasons cartridge heaters usually have higher watt densities than other heaters is that their installation usually is in such a way that the heat is usually removed quickly from the surface of the heater.? If your cartridge heater is extending out of the hole, you only have the surrounding air to remove the heat being generated by the heater.? Of course, metal is a much better conductor of heat than air.

This can cause an early death for a cartridge heater.? If you have to have a portion of your heater extending past the edge of the mounting hole, make sure you specify an unheated area at the end when ordering.
