A riser sleeve () for using when pouring metals into a casting mould includes a riser body (). The riser body () includes

Riser sleeve, method for producing a riser body for the riser sleeve as well as an expander element and core box for producing a riser body

A method for producing a feeder () that is intended for use in a casting mold used for the casting of metals and comprises a feeder body (), which encloses an inner cavity () as a feeder volume, consists of an exothermic and/or insulating material, has at least one lateral wall region () and a bottom region () with a feeder opening () arranged therein for connecting the inner cavity () of the feeder body () to the mold cavity of the casting mold during the casting operation and has a mesh-like fabric consisting of a refractory material covering over the feeder opening () therein, is characterized in that, in the course of the production of the feeder in a core shooter, a piece of fabric () of the mesh-like fabric is positioned in a pattern device () forming the shape of the feeder () in a core box () of the core shooter, in such a way that the peripheral region () of the piece of fabric () positioned in the bottom region () of the later feeder () is at least partially bent up in the direction of the lateral wall region () of the feeder body () and, during the shooting of the feeder (), the bent-up peripheral region () is surrounded by the material shot in and is anchored in the material of the finished shot feeder ().

Method for producing a feeder with a mesh-like fabric covering over the feeder opening thereof

In a method for producing a riser for inserting into a casting mold used for casting metals, the riser includes a riser body () surrounding an inner cavity () as a riser volume and is composed of an exothermic and/or insulating riser material (). To produce a single-piece riser body () in a two-part core box (), a cavity () reproducing the outer contour of the riser body () is formed and, in order to produce the inner cavity (), a reversibly expandable king () is set in the cavity () in such a way that, in the shooting of the riser body (), the wall region (), the cup region (), and the base region () of the riser body are formed by the riser material () introduced into the intermediate space () between the expanded king () and the inner wall () of the cavity ().
