Permanent casting mould has thick metal lining applied by applied using a modified high-temperature high-pressure diffusion process

A permanent mould has a cooling void at a predetermined distance from the surface. The void wall has a thick coating of non-frangible metal, applied using a high-temperature high-pressure diffusion process. A fissure-prevention modification is incorporated in those parts of the form wall where empirical experience indicates fissures may develop. The strength of the union between the metal coating and form is selectively reduced in those areas at risk from fracture.

Method for shaping workpieces without cutting

The invention describes a method for shaping workpieces without cutting. In this process, a casting mould has an outline which corresponds to the negative of the final shape of the workpiece. A wear-resistant layer is first applied to this outline, and is then covered by a reinforcing layer if so desired. Furthermore, the body of the actual workpiece itself is preferably cast from an alloy with a low melting point. The method is especially well suited for manufacturing deep-drawing dies workpieces, ingot moulds and all workpieces which must have a wear-resistant surface. ...

Casting die production for die casting machine

Improvements in and relating to the casting of non-ferrous metals

... 543,577. Making moulds. PARLANTI, C. A., and BOWEN, E. WINDSOR-. July 1, 1940, No. 11120. [Classes 83 (i) and 83 (ii)] Moulds for casting non-ferrous metals, e.g. brass, bronze, or aluminium or magnesium or their alloys, are formed by forging, machining, or casting from aluminium or an alloy thereof, the internal surface then being anodized. The surface may be first etched or otherwise roughened and before etching may be subjected to mechanical treatment to ensure closeness of grain or smoothness of surface. The external surface may be treated similarly. After anodizing, the surface may be treated with potassium dichromate or cobalt acetate with or without potassium permanganate &c. or with water at a high temperature to ensure continuity of the oxide coating and it may be impregnated with a lubricant which will also serve to reduce porosity, e.g. graphite. When the moulds are made by casting the moulds in which they are cast may be made according to the invention.

Moulded part with separate module for bridges, method for producing a mould, ceramic mould and cast part

In a process to fabricate a ceramic casting mould those areas that are subject to the greatest or have greater geometric requirements are formed separately. The form is a modular component consisting of two or more modules each with a void into which casting form material is introduced. The voids have heat bridges linking each void with the other. Further claimed are a commensurate ceramic form and a cast component.

Method for manufacturinf a core forming tool

A new core die is produced by producing ceramic core using initial core die, casting using ceramic ore, and carrying out specification measurements on obtained cast component in which when cast component deviates from desired values, initial core die is not modified but the ceramic core is in turn produced using the same initial core die and ceramic core is processed to form a modified core. The modified core is used for casting until the modification of ceramic core or modified core have the effect that cast component complies with the required specifications.

Die casting control method

A method for monitoring and/or controlling a die casting operation using the rate of coolant flow through cooling lines of a die and the amount of heat being removed from the die by the cooling lines.

Process for manufacturing a cylinder crankcase

Producing cylinder crankcase (10) comprising wet- and hanging bushes (16), comprises closing a casting mold, introducing at least one steel sleeve into the casting mold for forming at least one cylinder chamber (14), filling the casting mold with a molten metal, extending the steel sleeve after solidification of the melt, opening the mold, removing the cylinder crankcase from the casting mold, and inserting a wet hanging bush into the respective cylinder chambers. The sidewalls bounding the cylinder chamber, before inserting the bushes, are mechanically processed. Producing cylinder crankcase (10) comprising wet- and hanging bushes (16), comprises (a) closing a casting mold, (b) introducing at least one steel sleeve into the casting mold for forming at least one cylinder chamber (14), (c) filling the casting mold with a molten metal, (d) extending the steel sleeve after solidification of the melt, (e) opening the mold, (f) removing the cylinder crankcase from the casting mold, and (g) inserting a wet hanging bush into the respective cylinder chambers formed by the steel sleeve. The sidewalls bounding the cylinder chamber, before inserting the bushes, are mechanically processed, in which a first section of larger diameter is produced between a second axial section of smaller diameter and a third axial section of smaller diameter, which are formed by the steel sleeve.
