Pattern set-up (foundry)
The model means referred to in the metal foundry the preparation and the finished product of a workpiece , which serves to accommodate the casting liquid and thus to impart the final shape.
If castings with lost molds are produced, then “in addition to the actual model, there are also core boxes for the production of lost cores as well as other aids [...] which are not always directly used for shaping the later casting, but are essential for the entire manufacturing process of a complicated shape ".
Depending on the object to be produced, the following elements can be counted as part of a model setup: the models themselves, core boxes - which contain the spatial negative of the cores to be produced - technical elements such as core marks, loose parts, inserts, feeders and insulation parts - which ensure clean and precise production enable -, model accessories such as the casting system and feeder - which are necessary for molding or casting reasons - and aids such as drying trays, core assembly gauges , test gauges , press blocks as well as heating and gas supply devices.
After a model set-up has been completed, follow-up checks are necessary in order to be able to guarantee the subsequent accuracy of fit of the components to be created with it.
