The wall thickness control technology of blow molding machine:

The control of the wall thickness of the billet has been studied in recent years. In the early production of plastic products in China, the wall thickness of the billet is adjusted by manual manual adjustment, and the manual adjustment precision is low, so the wall thickness is not uniform, and the waste material is 50%. In recent years, the blank thickness control system has been adopted to control the parison wall thickness automatically in China's hollow plastic products. At present, the research on the wall thickness control system in China is relatively mature, but the application is less, especially in the large capacity hollow blow molding products. The reason is that there are still some problems in the key technology.

The structure of the wall thickness control system

There are two kinds of automatic control for parison wall thickness, axial control and radial control. For the radial control technology, China is still in the research stage, relatively speaking, the research of axial control is mature. In this paper, the axial control of parison wall thickness is carried out for large capacity blow molding machines above 200L.
