Beschreibung
Oberflächenbehandelter Kernnagel Description
Surface treated core nail

Kernnägel üblicher Produktion bestehen aus blankem, vierkantigem Draht. Zur Verbesserung der Haftung ist es üblich, die Nägel zu verzinken, wodurch eine leicht raue Oberfläche durch Zinkpartikel entsteht. Für manche Einsatzzwecke reicht die so erreichbare Haftfähigkeit im
Gießsand nicht aus.Core nails of standard production consist of bare, square wire. To improve adhesion, it is common to galvanize the nails, which creates a slightly rough surface due to zinc particles. For some applications, the adhesion achieved in this way is sufficient in the
Casting sand is not enough.

Der im Schutzanspruch angegebenen Erfindung liegt das Problem zugrunde, einen Kernnagel zu schaffen, der eine Oberfläche aufweist, die eine optimale Haftung im Gießsand
gewährleistet. Dieses Problem wird mit den im Schutzanspruch aufgeführten Merkmalen
gelöst.The invention specified in the protection claim is based on the problem of creating a core nail which has a surface which ensures optimal adhesion in the casting sand
This problem is solved with the features listed in the protection claim
solved.

Mit der Erfindung wird erreicht, dass durch die verbesserte Haftung des Kernnagels im
Gießsand Störungen im Produktionsablauf weitgehend vermieden werden.The invention achieves that the improved adhesion of the core nail in the
Casting sand disruptions in the production process can be largely avoided.
