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

摘要

The manufacture of polyethylene terephthalate (PET) containers is now very common, but there has been little research on energy saving in this manufacturing technique. This paper provides a feasible, simple, and low-cost energy-saving manufacturing technology for injection stretching blow molding (ISBM). This study is divided into two parts: an experimental part and a computational part by computational fluid dynamics (CFD). The principle and execution methods of the experiment and computation are delineated in the text. Sensor detection is used to confirm the result of CFD. The finished product produced by the proposed technique has a higher quality than a product made in a factory and the energy saving was approximately 14%. In the future, we will continue to study the integration of various technical details so that machine operators can better understand the methods of energy-saving operation and thereby contribute to environmental protection simultaneously.
