How to Choose a MaxDo MD Series Slitting Line in 2026
Use this verified 2026 selection guide to choose a MaxDo slitting line by width class, coil handling, quality risk, and documentation control.
Most slitting-line buying mistakes happen before the supplier sends a quote. Buyers often assume the model code explains everything, compare speed before defining width class, or use average production data instead of the real order mix. A better selection process starts with the production envelope, then moves into width class, coil handling, downstream quality risk, and finally the signed technical package.
Our MD Series covers four clearly differentiated width classes — MD-850, MD-1350, MD-1650, and MD-2200 — each engineered for a distinct production band. The right choice depends not on the widest model available, but on the real envelope your plant runs every day.
Start with the real production envelope, not with the brochure speed
Slitting performance is defined by tolerance, edge quality, strip tracking, and tension control — not by a single speed figure. The slitting head, tension section, divider tooling, recoiler, and
coil-handling equipment all shape the result. That means the correct selection sequence is broader than one speed number or one thickness label.
Before shortlisting a model, define the following:
| Selection Variable | What Must Be Defined | Why It Matters |
|---|---|---|
| Material specification | Actual material family, grade, and governing standard | Tool wear, edge condition, and process stability all depend on the real material definition |
| Thickness envelope | Minimum, normal, and maximum thickness in millimeters | Our models cover overlapping thickness ranges, so the contract must define the real working range |
| Width class | Maximum incoming width, narrowest finished strip, and typical slit count | Width class is the clearest differentiator across our MD Series lineup |
| Coil-handling burden | Coil weight, OD, ID, loading direction, crane or forklift method | Coil handling drives the uncoiler, recoiler, coil car, layout, and safety scope |
| Downstream process | Tube, roll forming, stamping, resale, or another use | The line should be selected around the next process, not around the first cut alone |
| Documentation scope | FAT, SAT, training, controls, spare parts, and acceptance criteria | Defining this upfront eliminates ambiguity at commissioning |
If your plant still mixes gauge language and metric thickness inside the same RFQ file, clean that up before supplier review. Our sheet metal gauge thickness chart
y metal processing glossary are built exactly for that internal alignment step.
Our MD Series lineup
We offer four MD Series slitting platforms. Each model is defined by its working width range,
coil-handling capacity, and line speed — not by an arbitrary tier label. The table below reflects our current published specifications.
| Modelo | Tamaño de trabajo | Gama de espesores | Peso de la bobina | Velocidad | Potencia total |
|---|---|---|---|---|---|
| MD-850 | 300-820 mm | 0.3–3.0 mm / 1.5–6 mm / 2–8 mm / 4–12 mm | 10–35 t (customizable) | 1-60 m/min | 93 kW |
| MD-1350 | 300-1350 mm | 0.3–3.0 mm / 1.5–6 mm / 2–8 mm / 4–12 mm | 10–35 t (customizable) | 1-80 m/min | ~136 kW |
| MD-1650 | 300-1650 mm | 0.3–3.0 mm / 1.5–6 mm / 2–8 mm / 4–12 mm | 10–35 t (customizable) | 1-80 m/min | ~294.5 kW |
| MD-2200 | 300-2150 mm | 0.3–3.0 mm / 1.5–6 mm / 2–8 mm / 4–12 mm | 10–35 t (customizable) | 1-250 m/min | ~422.5 kW |
Thickness speed follows a real physical rule across all four platforms: the thicker the incoming
material, the lower the practical running speed. Width class is the clearest public differentiator; shortlist around your real width envelope first, then confirm the thickness and speed requirements with our engineering team.
How to decide between compact, mid-width, heavy-duty, and ultra-wide platforms
Once the production envelope is defined, the shortlist becomes straightforward.
Use the compact-width platform when the plant genuinely lives in the 820 mm class
Our MD-850 is the right starting point when the plant’s real order mix is narrow, floor space is tighter, or the profitable work clearly belongs in the compact-width range. It is not the right default just because the average coil is small. Running an 820 mm platform confidently at capacity is more productive than idling a wider machine.
Move to the mid-width platform when the order book consistently needs the 1350 mm class
Our MD-1350 is the right choice when the plant needs more working width, more slit-planning freedom, and a platform that better matches a mid-width production band. Its 1–80 m/min speed range gives operators meaningful pace flexibility across the thickness envelope.
Move to the 1650 mm class when width and handling burden exceed mid-range assumptions
Our MD-1650 is the stronger fit once width, coil handling, and process burden move beyond mid-width territory. At this stage, review not only width but also coil handling, layout, controls, and downstream quality risk together — they all scale at this class.
Move to the 2150 mm class only when ultra-wide work is genuinely part of the business model
Our MD-2200 is the widest platform in our lineup. It should be specified when ultra-wide work is recurrent or strategically important — not when the plant is buying for hypothetical future work. At 1–250 m/min and ~422.5 kW, it is built to handle serious volume at full width.
Pro tip: Choose around the work that drives margin and scheduling pressure. The occasional
extreme order should not define the platform unless it is central to the business plan.
The questions that should change the shortlist
The right buyer questions are often more useful than a longer feature list.
| Buyer Question | Why It Matters | Shortlist Impact |
|---|---|---|
| Does the slit coil feed roll forming, tube making, or stamping? | Slitting quality directly affects downstream forming and fabrication results | Strip tracking, edge quality, and recoil stability should carry more weight than speed alone |
| Are the highest-margin orders near the top end of the width class? | A platform that constantly works at its limit becomes harder to run profitably | Move the shortlist up one width class earlier |
| Has supplier coil weight increased over time? | Coil handling can force a platform change even when thickness has not changed much | Re-check uncoiler, recoiler, coil car, and layout assumptions |
| Does the customer require standard-based material documentation? | Material purchased to a real standard has to be stated clearly in the RFQ | Add the standard family and real thickness envelope to the commercial file |
| Does the plant require recipe management, controls integration, or stronger documentation? | Our lines ship with PLC controls, but the full control scope should be specified in the quote | Make controls and documentation part of the quotation, not an afterthought |
Common mistakes in MD Series slitting-line selection
Common mistake: Comparing only maximum speed. Speed is easier to compare than slit recipe, tension control, and coil-handling scope. The correct comparison starts with width class, handling burden, and downstream quality requirements.
Common mistake: Sizing the line around the average order. The profitable edge cases are often the jobs that stress width, coil handling, or separator demands. They need to be part of the production file before we can recommend the right platform.
Common mistake: Skipping the downstream process definition. A line selected without a clear downstream process definition is likely to be over- or under-specified. Tell us what happens to the slit coil after it leaves the line.
Common mistake: Using a cut-to-length page as evidence in a slitting-only shortlist.
Our CTL and slitting lines share some model family names but serve fundamentally different
processes. Keep the two product categories separate when building the RFQ.
Quote-ready buyer checklist
Before asking us to recommend a platform, build a proper buyer file.
- Attach the material program with grade family, governing standard, and volume share.
- Attach the thickness envelope and width envelope in millimeters.
- Attach the real slit recipes, including narrowest strip and highest slit count.
- Attach coil weight, OD, ID, loading method, crane or forklift limits, and floor-space constraints.
- Attach downstream quality requirements and the defect logic used by production or customers.
- Attach required controls, documentation, FAT, SAT, training, and spare-parts expectations.
If the plant is still deciding between slitting and cut-to-length, close that process decision
before final approval. Our most useful references for that comparison are
