Abstract

Abstract: In the production of hollow products, in order to ensure uniform wall and save material, an electrohydraulic control system was designed for blow molding machines based on the LabVIEW software, with a high performance electrohydraulic proportional valve as the core of control system. The system relied on high speed operation and precision control, and closed cycle control of wall thickness was achieved. Test of the system showed that it had high accuracy and antiinterference, thus ensured smooth operation of large hollow products.

Key words: low molding machine, LabVIEW software, electrohydraulic control, design
