FIELD: process engineering.
SUBSTANCE: invention relates to hot injection and may be used for fabrication of long article package supports. Proposed method comprises placing initial polymer tubular billet on spatial carcass mandrel with ledge supports and billet plastic deformation. For this, billet is heated to elastic state at sections between mandrel carcass supports, external forming tool is pressed against heated sections to shape the latter as required.
EFFECT: whatever depressions on tubular billet.
