Shuliy shipped a model 60-4 screw flight cold rolling machine to a South African fabricator for producing continuous seamless spiral blades from SPHC strip 12\u201360 mm wide and 1.5\u20133 mm thick.<\/p>\n\n\n\n

The 19 kW line forms flights with outer diameters of 30\u2013200 mm and pitches of 20\u2013300 mm, holding inner hole, outer diameter, and pitch tolerances within \u00b13 mm for small screw conveyors and feeding devices.<\/p>\n<\/div><\/div>\n\n\n\n

Shuliy has just shipped a screw flight cold rolling machine, model 60-4<\/strong>, to a customer in South Africa<\/strong>. The continuous line cold-rolls screw flights from SPHC strip 12\u201360 mm wide and 1.5\u20133 mm thick<\/strong>, producing seamless spiral blades with an outer diameter of 30\u2013200 mm<\/strong> and a pitch of 20\u2013300 mm<\/strong> \u2014 holding a tolerance of \u00b13 mm<\/strong> on inner hole, outer diameter, and pitch within a total installed power of only 19 kW<\/strong>.<\/p>\n\n\n\n

What Did the South Africa Customer Need?<\/strong><\/h2>\n\n\n\n

The buyer is a South African fabricator that makes small-diameter screw conveyors and feeding devices. Their product range sits squarely in the thin-gauge zone: screw flights rolled from strip 1.5\u20133 mm thick, with finished outer diameters between 30 and 200 mm and frequent pitch changes between 20 and 300 mm.<\/p>\n\n\n\n

Outsourcing this flighting meant long lead times and no control over pitch accuracy. Ordering the 60-4 cold rolling machine<\/strong> brings the whole process \u2014 feeding, rolling, shearing \u2014 into their own workshop.<\/p>\n\n\n\n

Why Choose a Screw Flight Cold Rolling Machine for Thin Flighting?<\/strong><\/h2>\n\n\n\n

Spiral blades are made by two main processes. A screw flight cold rolling machine<\/strong> feeds a steel strip through roller dies and forms a seamless, unbroken spiral at full line speed \u2014 the standard choice for plate under roughly 6 mm. Sectional (single-piece) die forming<\/a> presses thick plate segment by segment and suits 8\u201330 mm material. At 1.5\u20133 mm, cold rolling wins on speed, surface finish, and consistency \u2014 the two routes are compared in our guide on how to choose a suitable auger flight forming machine<\/a>.<\/p>\n\n\n\n
