Abstract (en)

[origin: DE19534984C1] To detect waste items and to avoid recurrent wastage, the invention relates to a method for quality control in core or shell shooters (1), moulding material being shot using a shooter into an openable tool (2) and being solidified therein to form a moulding (3), i.e. core, shell or the like, and the moulding (3) being removed when the tool (2) is opened. The method is such that when the tool (2) is opened and/ or during removal and /or after removal, the moulding (3) is measured without contact, the measuring values are supplied to a computer (6), are optionally processed therein and compared with stored control values, and the moulding (3) is identified as waste when a predetermined or definable deviation from the control values is detected.
