The fixed mode of the heating rod
A heating rod is also calledSingle head heating tubeAlso called single end electrothermal tube, compared with the double electric heating tube,Single head heating tubeBy the end of the outlet, generally adopts star connection method. Single head heating tube is generally used for mould heating or air dry, mainly is the mold heating single head electric heat pipe, drilling directly into the mold, the outlet end of the external pad is fixed, prevent electric heating tube mobile.
Special attention is, makingSingle head heating tubeTo consider with the diameter and the pore diameter of the template, the electric heating tube diameter is too large, resulting in heating tube could not load the hole position, and consider the expansion factor of tube after heating, the inconvenience to the maintenance; in addition to considering pipe diameter can not be too small, can not be reserved between the big and the hole wall space, affect the heat transfer performance of the electric heating tube and the service life. So we reorder when single head heating tube to the attention of the caliber size, but also clearly before ordering is positive or negative tolerance tolerance, I hope everyone can be set to the appropriate product
