A centrifugal casting apparatus for different materials may include a mold having a shape corresponding to a shape of an outer surface of a casting to be produced, and having a cavity receiving molten metals therein, a molten metal guide inserted into the mold and configured to guide the molten metals so that the molten metals are separately injected into the mold, a guide fixing support fixing the molten metal guide to a predetermined position, and a motor configured to rotate the mold around a rotation axis.

A casting mold supporting structure is provided herein which includes a support roller for supporting a part of a casting mold that is used in centrifugal casting. The casting mold has a supported surface (that is, a side surface of an end portion of the casting mold which end portion has a circular truncated cone shape) at which the casting mold is supported by the support roller. The supported surface is inclined with respect to a rotation axis of the casting mold.

Various enhanced features are provided for centrifugal casting apparatuses, rotatable assemblies, and molds for casting products from molten material. These enhanced features include, among others, tapered gate portions positioned adjacent to the cavities of a mold, extended and shared gating systems, and detachable mold structures for modifying the thermodynamic characteristics and behavior of molds during casting operations.

A water-cooled centrifugal pipe casting machine includes a sector ladle tilting system, a pouring runner, a pipe mold and a pipe removing device. The pipe mold is provided to a travel system, and rotation of the pipe mold is controlled by a pipe mold rotating system. By using a servo motor driving the sector ladle tilting system, by using a parallel four-bar linkage structure tilting a sector ladle, and by using a variable frequency motor controlling the movements of a rack and a gear of a travel driving system, a constant amount of hot metal flowing out of the sector ladle per unit time can be ensured and a constant traveling speed of the centrifugal pipe casting machine are achieved. As such, uniformity of the wall thickness of the casting pipes can be ensured, the quality thereof can be improved, and materials required can be saved.

A multiple pressure casting mold includes a mold part having upper and lower molds, each having molten metal injection ports and the molded product accommodating parts for accommodating the molten metal for the molded product, a rotating unit for rotating the mold part so as to allow the molten metal injected through the molten metal injection ports to flow into the molded product accommodating parts, and a molten metal injection control unit having upper and lower pressing parts for pressing the molten metal injected through the molten metal injection ports so as to allow the molten metal to flow into the molded product accommodating parts with the rotating unit.

The present disclosure relates to an apparatus to cast tubes of sluggish material and a process thereof. The apparatus comprises at least one cylindrical casting mold, heating means, at least one set of rollers, a driving member, at least one tank, a spray nozzle, at least one tundish, a reinforced snout, cooling means and a drive control unit. The mold is configured to receive the molten sluggish material therein. The rollers are configured to abut an operative outer surface of the casting mold. The driving member is configured to spin the casting mold in an operative configuration of the apparatus to cast the tube of a predetermined inner diameter (ID), outer diameter (OD) and a predetermined length. Since, the addition of fluidity enhancer increases the fluidity of the molten sluggish material inside the mold, advantageously the smaller diameter of the tubes are easily produced by this process.

A molding machine for molding material is provided. The machine includes a cavity to be filled with molten metal and a conduit system leading to the cavity, thus forming a system of interconnected hollow spaces. At least one pressure member is moveable in at least part of the conduit system. A centrifugal pump in fluid communication with a reservoir of molten metal is provided, the pump providing molten metal to the hollow space receiving the at least one pressure member.

Methods for producing a rotationally symmetrical, hollow metallic workpiece may involve rotating a casting mould about a rotation axis and introducing a melt into the casting mould. The melt may be thrown towards an inner contour of the casting mould by centrifugal forces, and hollow bodies may be added to the melt. Furthermore, a device for producing a rotationally symmetrical, hollow metallic workpiece may include a casting mould that is rotatable about a rotation axis, a feeder device for introducing a melt into the casting mould such that the melt is thrown towards an inner contour of the casting mould by the effect of a centrifugal force, and a metering device for adding hollow bodies to the melt.
