Abstract:

Hot plastic profile produced by extrusion die is cooled down and calibrated by calibrator. Therefore, the cooling and calibrating ability of the calibrator directly influence the quality and output of the profile. The key is to design the distribution of cooling channels in calibrator. By analyzing the heat transfer process during cooling in calibrator, the cooling process of plastic profile in calibrator is simulated. Based on the finite element analysis results, the optimization objective is established to obtain the cooling efficiency and uniformity of each node in the profile cross sections of the calibrators exit and finish the optimization design of the cooling channels positions.
