1, use the die repair to improve the smoothness of the insulation aluminum coil
Repair mode is both at home and abroad for the smoothness of the solution of bad extrusion materials commonly used, insulation plane gap aluminum coil is bad, and the mold velocity is not uniform, the size or the angle change of the diversion channel, or change the work with the length to effectively adjust the metal flow, so that the uniform velocity, eliminate defects the plane gap is bad. Harbin Dong Xing Aluminum Co., Ltd could provide you with Aluminum coated coil 3004-O.
2. Use the off-line finishing to correct the flatness of the heat preservation aluminum coil
According to the specific characteristics of insulation aluminum coil flatness outoftolerance, and pieces of the rational allocation of offline finishing machine, then use a flat products ultra poor of roller, by constantly adjust the height and position of roll film, to be the only plane of the aluminum coil insulation degree after passing the height and position of the fixed roller sheet then, the product of the batch off-line finishes. Harbin Dong Xing Aluminum Co., Ltd is a competent and reliable Aluminum PVDF coated coil manufacturer.

3, the on-line finishing is used to correct the flatness of the heat preservation aluminum coil
Online finishing is according to the principle of offline finishing, installation of bearing and roll film based on the original press outlet guide device on the height and position of roller sheet to change the deformation of the aluminum coil insulation pressure to produce a certain amount of insulation, let aluminum coil flatness control within a reasonable range, so as to achieve the purpose of online finishes.
