METHOD OF RADIAL MOULDING OF PARTS MADE FROM MATERIALS WITH RANDOM STRUCTURE Russian patent published in 2010 - IPC B21F45/00 B21J5/00 B30B15/02 

FIELD: process engineering.

SUBSTANCE: invention relates to machine building and can be used in machining random structure materials, particularly metallised rubber. Proposed method comprises producing wise sections in the form of extended spirals, forming flat workpiece from spiral sections, coiling into roll, placing produced workpiece in injection mould and moulding said workpiece in several passes. Elastic medium element is fitted into mould on one side of workpiece or on its both sides. Moulding the workpiece is performed by axial squeezing of workpiece together with elastic medium elements that convert axial compression in radial pressure onto workpiece.

EFFECT: providing necessary elastic properties on moulded part in both radial and axial directions, possibility to produce wide range of solid and hollow parts.
