ABSTRACT:
A method for injection-molding workpieces in a mold of an injection-molding machine is disclosed. The method provides a means of conducting test cycles during the initial setup of the machine at reduced speed. In a multi-cavity mold all of the workpieces are demolded by means of a handling system having a workpiece carrier system receiving and holding all workpieces in a regular pattern. The workpieces are inspected on the workpiece carrier system for determining whether all of the cavities have been filled with plastic material and whether the workpieces are of a predetermined quality. If this is not the case, the necessary adjustments are made and the test cycle is repeated. If all of the workpieces are of a predetermined quality, the machine is switched to automatic production at high nominal speed.
