What Does a Coil Line Cost to Run Each Year?Oct 13,2026
A five-line annual cost model for a coil line: power, rolls and wear parts, spares holding, scrap and downtime. Worked through on a 200 SPM line running 1.2 mm SPCC, where scrap turns out to be five times the power bill.
Which NC Servo Feeder Setup Suits Perforated Coil?Oct 13,2026
This is the trail from a short feed to the roll position, the three settings that fixed it in one afternoon, and the open-area and feed-length limits where the same approach stops working.
Why Does a Decoiler Brake Overheat on Long Runs?Oct 13,2026
The article separates a tension fault from a brake fault with one test, works the drag torque for a 5-tonne coil down to the core radius, and marks the cases where a hot brake is normal and should be left alone.
How Does Strip Get Guided Into an NC Servo Feeder?Oct 13,2026
A downstream-to-upstream setup routine for an NC servo feeder: pass line, exit guide squareness, roll gap, entry gap and a full-coil verification, with the three cases where no guide setting can help.
How Much Back Tension Does an NC Straightener Feeder Need?Oct 13,2026
Back tension follows strip section and yield strength, and a fixed payoff drag over-brakes the strip as the coil empties. A worked calculation on 300 mm by 1.5 mm SPCC, a sensitivity check on width and thickness.
How to Prepare a Plant Before a Coil Line Arrives?Oct 12,2026
This guide sequences the jobs that must finish before the machine ships: foundation and anchor layout, slab loading, power and air capacity, and rigging access.
Why Do Thin Laminations Slip in a Straightener Feeder?Oct 12,2026
This article separates slip between the rolls, after the rolls and before the rolls, then ranks the causes by what you can measure. It covers oil film, glazed rolls, pilot release timing and die drag.
Which Coil Loading Method Fits Your Decoiler?Oct 12,2026
This article compares crane and C-hook, coil car, ramp loading and twin mandrel, and maps each one to coil mass and changeover rate. It also names the cases where the most automated choice is the wrong purchase.
Is Your NC Servo Feeder Sized for Short Feeds?Oct 12,2026
This article works the arithmetic for feed length, stroke rate and available window, including a worked example at 60 mm and 200 SPM. It shows why shorter feeds are harder, and where the formula stops predicting.
What Happens When a 3-in-1 Feeder Runs Thin Stock?Oct 12,2026
This field case follows the measurements, explains why large rolls cannot bend thin strip past yield, and lists the four setup changes that fixed it. It also states where a wide-range machine genuinely cannot help.
Can You Test a Straightener Feeder Before It Ships?Oct 10,2026
This guide covers the five readings that belong on a test sheet, what a week of run-off actually costs, the four gaps that let a clean report mislead you, and the six sentences.
How Does a Straightener Feeder Handle 6 mm Heavy Gauge?Oct 10,2026
This article follows six parameters that move when thickness doubles, shows why leveling force scales with the square of thickness, compares an integrated machine with separate units at 6 mm.
Is Your Decoiler Payoff Speed Matched to the Press?Oct 10,2026
This article works a 300 mm pitch at 60 SPM through the arithmetic, shows how coil diameter changes the answer, and lists what to measure on the first coil.
How Much Drift Does a Loose Servo Feeder Coupling Cause?Oct 10,2026
This field case traces 3 percent scrap to 0.15 mm of lash in an elastomer encoder coupling, shows the five checks that isolated it in ninety minutes, and explains why the fault is invisible.
Which Roll Settings Mark Strip in a Straightener Feeder?Oct 10,2026
This article separates four patterns by their spacing, gives the order of checks that clears most cases without spending money, and states plainly when the marks arrived with the coil.
