Forged Discs
Open-die forged discs supplied as-forged, rough machined or finish machined to an approved drawing.
Disc forgings
Large & Custom Disc Forgings
Drawing-based forged discs, rotor discs, gear blanks and tube sheets for energy, pressure equipment and heavy industrial applications.
Disc forging product types
Manufacturing routes
by disc geometry.
Disc profile, section changes, material, heat treatment, machining allowance and inspection level are reviewed as one manufacturing route. These are drawing-based manufacturing capabilities, not stocked catalogue products.
Rotor Discs
Rotor disc forgings reviewed against section geometry, mechanical properties, machining and inspection requirements.
Gear Blanks
Forged disc blanks prepared with project-specific machining allowance for subsequent gear manufacture.
Tube Sheets
Forged tube-sheet blanks manufactured to the customer drawing, material specification and required inspection scope.
Solid Disc Blanks
Solid circular blanks produced for subsequent heavy machining and equipment-component manufacture.
Bored Disc Forgings
Disc forgings with a drawing-specified center opening, subject to engineering review of the forming and machining route.
Machined Disc Forgings
Forged discs supplied rough or finish machined according to the approved drawing and inspection stage.
Custom Profile Discs
Drawing-specific disc profiles developed after review of finished geometry, section transitions and delivery condition.
Manufacturing range
Drawing-specific
disc capability review.
No unverified diameter, thickness, bore or weight limits are published. Engineering confirms feasibility from the disc drawing, material grade, section geometry, final properties, machining route and inspection requirements.
