Method for monitoring moderate temperature device of plastic processing tool of injection molding machine, involves comparing flow meters data which shows pressure fluctuations in flow line or in return line

摘要

The method involves connecting two branch lines (4,5) in parallel between a flow line (3) and a return line (6). The flow meters (8,8') are connected at the branch lines respectively. The presence of leakage is determined by comparison of the flow meters data which shows the pressure fluctuations in the flow line or in the return line.
