High Efficiency Strut Channel Roll Forming Machine — Running Cost View

HOPEX-High Efficiency Strut Channel

The purchase figure is easy to compare. Running cost is not. This page looks at the four items that actually determine what a high efficiency strut channel roll forming machine costs to operate over its life.

Cost Item 1 — Energy

Total connected load is 69 KW at 380 V. Connected load is not consumption: the punching and cutting stations draw current only during their cycle, so average draw during steady forming is lower than the nameplate figure.

Cost Item 2 — Tooling Life

Tooling is the largest recurring consumable in roll forming. Material selection is where that cost is decided.

Cost Item 3 — Labour per Tonne

Labour cost per finished part falls as line speed rises, provided quality holds. This line runs at 10 – 15 m/min with in-line punching, so there is no separate punching operation and no second handling of the part.

Cost Item 4 — Scrap and Rework

Scrap is generated by section variation and by hole position error. The gearbox and arch frame drive maintains constant speed under load, which keeps the punch pitch consistent instead of drifting as the mill slows.

Where Efficiency Actually Comes From

• Four widths on one mill — 135 mm, 157 mm, 177 mm and 197 mm, so mixed orders do not need a second line.
• In-line punching — removes a whole secondary operation.
• 10 – 15 m/min constant forming speed — predictable output planning.
• 20000 kg frame mass — stability that protects tolerance and reduces rework.

Specification Summary

Delivery Planning

Lead time is 75 days for a single set and 90 days for 2–5 sets, which should be built into project scheduling rather than treated as a delivery detail. The line ships at 2600 × 300 × 200 cm with a gross weight of 20000 kg, manufactured in Tianjin, China.

Running Cost FAQ

Q1. Does 69 KW mean the line consumes 69 KW continuously?

No. 69 KW is the total connected load. Punching and cutting stations draw current only during their cycle.

Q2. What drives tooling replacement cost?

Material selection. Cr12 rollers, 40Cr shafts and Cr12MoV blades are each chosen against their dominant failure mode.

Q3. How does the line reduce labour cost?

In-line punching removes a secondary operation, and the part leaves the mill finished.

Q4. What causes scrap in strut channel production?

Section variation and hole pitch drift. Constant drive speed and rigid tooling address both.

Q5. Does running four widths slow production?

No. Forming speed remains 10 – 15 m/min across the range.

Q6. What warranty is provided?

2 years on core components.
