Hydraulic Sectional Forming Machine for Large Thick Screw Flights

Nov 12,2026

Hydraulic Sectional Flight Forming for Large-Diameter Thick-Plate Flights

A hydraulic sectional flight forming machine is suitable for large-diameter thick-plate flights when the press tonnage, die envelope and frame rigidity are rated for the specific thickness–diameter–material combination. It is not a universal “thick plate” solution. Some hydraulic flight presses handle 3000 mm OD and 60 mm plate; others are limited to roughly 800 mm OD and 12 mm thickness. The method is appropriate, but the machine must be matched to the job.

Working Principle and Why It Suits Thick Plate

Sectional forming produces one flight segment per press cycle. A hydraulic cylinder drives a die into a plate blank, bending it to the required helix geometry. The segment is later welded or assembled into a full flight. Because force is applied locally and the die defines the shape, the process can handle plate that continuous cold rolling cannot: thick carbon steel, stainless steel, and wear-resistant grades such as NM400/450/500 and Hardox. A Spiral Blade Forming Machine configured for sectional production gives flexibility in diameter, pitch and thickness without dedicated continuous rolls.

Critical Limits Buyers Must Verify

The headline “maximum thickness” is not enough. Buyers should require capacity confirmation at the actual OD, ID, pitch and material grade:

Tonnage at the required thickness. Thicker and stronger plate needs more force; a machine rated for 12 mm mild steel may not form 20 mm Q345 or 12 mm Hardox.

Die size and segment chord length. Large-diameter flights require longer segments and larger dies.

Frame stiffness and repeatability. Deflection under load causes pitch drift and diameter inconsistency.

Springback control. High-strength grades require more over-bend; the press and die must accommodate it.

For a structured selection framework, see How Can You Select a Screw Flight Forming Machine for Mining and Heavy-Duty Applications?. A Continuous Screw Flight Cold Rolling Machine is generally preferable for thinner strip and high-volume continuous output; hydraulic sectional forming is the appropriate alternative when thickness, material or diameter exceeds that envelope.

When to Choose Hydraulic Sectional

Choose hydraulic sectional forming when plate thickness exceeds continuous cold-rolling capacity, the material is high-strength or wear-resistant, the diameter is large, production is low-to-medium with size variation, or segments are required for site assembly. Compare the two approaches directly in Sectional Screw Flight Forming Machine vs. Continuous Flight Forming Machine.

Procurement Checklist

Submit OD, ID, pitch, direction, plate thickness, material grade, segment/continuous requirement, tolerance, annual quantity and maximum segment weight. Ask for a sample at the most demanding combination—which may be a thick, tight-pitch, high-strength segment rather than the largest-diameter one. Confirm die availability and changeover time before placing a thick-plate order.
