Injection molding machine need make good testing before machine shipments, the injection machine not less than 4 h (or 3000 times) continuous idle running test, which at the same time, need test the parallel degree between move and fix mould working plane, manual, semi-automatic and automatic three action operation situation, safety protection facilities and operation reliability of hydraulic system, the oil temperature change and working noise test, the necessary data in the equipment provided by the certificate of approval. The testing results of the data should be accord with JB/T7267-2004 standard.

Injection molding machine examines information including the space of the screw and barrel of the injection machine, Screw diameter, tolerance of parallel degree between move and fix mould working plane and Radius of the nozzle etc…
