The Study of Infrared Heating on PET Bottles by Experiment and Adaptive Finite Volume Method

Abstract

Stretch-Blow moulding (SBM) fabricate process is a well known method to produce PET bottles. During the construction procedure, PET surface temperature distribution controlled by infrared heating is the key factor about manufacture technique for the better quality of PET. This paper focuses on how to measure and estimate temperature distribution on the surface of semi-transparent polymers so that we can make sure the proper position and intensity of the infrared lamb. We use infrared camera to detect the real temperature distributions and C++ object-oriented programming to estimate the infrared radiation (IR) results by adaptive finite volume method (Adaptive FVM). The numerical results have been compared with experimental results and the consequence is satisfied. Multiple lambs’ cases and the interior temperature distribution in PET will be discussed in future.

Energy-saving Manufacturing Technology for Heating of Injection Stretching Blow Molding Machine

“…The objective of our investigation is to find better energy-saving manufacturing parameters of the CPSB-LSS12 stretch blow machine of ChumPower Company while maintaining the product quality by both experimental and computational methods. In our previous research, (8) the calculation and analysis of the results of infrared heating were carried out and verified by experiments. Here, we provide a computational method to analyze the reused heat flow field in the heating box for preventing the cooling of the heated parison and an experimental method with a real machine to find out how to use the minimum number of infrared lamps and the minimum operating power of each lamp that can meet the product quality requirements.…”

Estimation for Temperature Distribution of PET Preform Surface under Multiple Lamps

“…If the error is big, then the mesh should be refined in order to increase the precision of the result. [5] After all computation process are finished, we use the results about all parameters to do the real work on machine.…”
