The speed of molding injection glass bottle standard consultation (II)

normal>nth= "12" year=1000mm/min is mainly used for the automatic return of the tensile testing machine after the completion of a group of experiments. "1899" is classified according to the loading method: static load testing machine (static) and dynamic load testing machine (dynamic)>14.1.5 other specifications and sizes use the accuracy equal to or higher than value= ".02" unitname= "mm">0.02 to complete the measurement of various calipers with multi-channel closed-loop control mm
