MD Series Material Risk Boundary Checklist
An MD series material risk boundary checklist for slitting RFQs covering grade, strength, coating, surface risk, strip program, edge quality, model route, FAT/SAT samples, cases, and support handoff.
This page is the MD series material risk boundary checklist in the MaxDo slitting topic network. It should answer one narrow question: what material evidence must a buyer prepare before deciding whether an MA or MD slitting route can process the job reliably? It is not a product specification page, not the slitting process core page, not a maintenance manual, and not a general material guide.
For the broader process choice between slitting and CTL by material behavior, use the slitting or CTL by material decision page. This support page stays narrower: it converts material grade, strength, coating, surface risk, edge quality, strip program, and model-boundary data into a slitting RFQ file.
Material Risk Boundary
Material compatibility should be treated as a risk boundary, not a yes-or-no material list. Carbon steel, stainless steel, aluminum, galvanized steel, pre-painted coil, copper, and brass can all be slit, but each material changes the cutting load, surface protection, blade wear, tension behavior, recoiling quality, and inspection plan. The RFQ should name the normal material file and the edge cases separately.
| Material evidence | Why it changes slitting risk | RFQ record to attach |
|---|---|---|
| Grade and strength | Changes cutting load, burr risk, blade wear, and arbor load | Grade, temper, yield/tensile range, and supplier material sheet |
| Thickness range | Moves the project between compact, mid-width, and wider model routes | Minimum, normal, maximum, and future thickness expectations |
| Coating or finish | Controls roller marks, guide contact, separator choice, and packing risk | Coating type, exposed surface, scratch limit, and inspection method |
| Strip program | Connects material behavior to finished widths, strip count, trim, and recoiling | Finished strip widths, count, trim allowance, ID/OD, and packing method |
| Acceptance standard | Defines whether the material can be released after trial or needs correction | Width tolerance, burr limit, camber limit, surface hold, and sample count |
Separate Cutting Risk From Surface Risk
A material can be easy to cut and still difficult to ship as acceptable strip. Aluminum and pre-painted coil may need careful surface handling, separator settings, low-mark contact points, and packing control. Stainless steel may need more attention to blade condition, edge load, work hardening, burr, and recoiling stability. Mild or carbon steel may be more forgiving, but scale, thickness, strength, and long run length still affect setup and wear.
Use the slitting blade setup standard when the buyer needs clearance, spacer, knife condition, and first-coil release logic. Use the slitting width tolerance measurement protocol when tolerance wording must be added to the RFQ. Use the slitting deformation control checklist when residual stress, strip wave, camber, or recoil shape is the real risk.
Route the Material File to the Correct Model Boundary
Model routing should follow material load and strip program, not only coil width. Compact, thin, surface-sensitive jobs may begin with MA-850. Mid-width mixed material programs can compare MA-1350 or the 1350mm slitting RFQ checklist. Wider, heavier, or high-throughput service-center programs should compare MD-1650, MD-2200, and the MD-1650 vs MD-2200 model boundary checklist.
After the boundary is clear, review the metal slitting machine category and the MA and MD model selection page. Product pages carry model-specific entity proof; this support page carries the material-risk file that should be attached before model comparison.
FAT and SAT Material Samples
A material compatibility claim should be tested with representative samples. The FAT file should define the material family, grade, thickness, coil width, strip widths, speed condition, burr limit, width tolerance, surface inspection method, recoiling target, and correction rule. The SAT file should repeat the critical checks on site with the buyer’s material handling, operator workflow, inspection tools, and packing route.
- Normal sample: the material and strip program expected to run most often.
- Edge sample: the hardest grade, coating, width, thickness, or surface requirement the buyer expects to accept.
- Release record: measured width, burr, camber, surface marks, recoiling result, and open corrective action.
Use Case Evidence Without Turning This Into a Case Page
Case evidence should support material-risk judgment. For stainless service-center strip, compare the India precision stainless slitting case study and the Saudi Arabia stainless steel slitting case study. For surface-sensitive nonferrous behavior, compare the aluminum alloy slitting case study. These case pages provide delivered evidence; this page remains the material-risk intake checklist.
Material Compatibility RFQ Checklist
- Material family, exact grade, strength range, thickness range, coating, and exposed surface.
- Incoming coil width, coil weight, ID/OD, normal job file, and edge-case material file.
- Finished strip widths, strip count, trim, burr limit, camber limit, width tolerance, and downstream use.
- Blade setup assumptions, separator method, recoiling target, packing route, and inspection method.
- FAT/SAT samples, support expectations, spare parts, training, documentation, and escalation contacts.
For training, spare parts, service boundary, documentation, remote support, warranty rules, and escalation records, use the coil processing equipment support evidence matrix. To ask MaxDo to review material compatibility, send grade, thickness, strength, coating, strip program, edge target, setup assumptions, FAT/SAT sample needs, and preferred model boundary through the contact form.
