Delayed action

Any of these slide mechanisms may have a delay built in. The designer may thus sequence the order of slide pulls if necessary, or may cause a slide to wait until some other action in the tool is done before activating. Delay on mechanical slides is accomplished by simply leaving an air gap behind the pecker pin or cam. Then as the mold opens the slide does not move until the cam crosses the air gap and begins to push upon the slide. In hydraulic slides delay is accomplished electronically by the molding machines computer.
