| Application Compatibility | Machine configuration must match chipboard, grey board, honeycomb board, or other specified sheet materials. | Supported board thickness, density range, sheet dimensions, moisture conditions, and edge-quality requirements. | Send representative material samples and require a documented trial result with photographs, measurements, and operating parameters. | 12% |
| Slotting Accuracy | Positioning accuracy and repeatability should be stated as measurable values, not only described as “high precision.” | Slot position tolerance, slot-width tolerance, depth control, repeatability, and calibration procedure. | Inspect at least 20 consecutive workpieces and compare slot location, width, and depth with the approved drawing. | 14% |
| Slot Dimensions and Tooling | Tooling should cover the required slot widths, depths, lengths, and corner conditions. | Blade or cutter material, standard tool sizes, custom-tool capability, tool-change time, sharpening method, and spare-tool availability. | Request a tooling list, tool-life records, sample cuts, and the estimated annual cost of consumable tooling. | 10% |
| Production Capacity | Rated speed should be supported by usable output, not only by no-load travel speed. | Sheets or pieces per hour, loading method, changeover time, scrap rate, cycle time, and performance under continuous operation. | Use a time-stamped production trial with the buyer’s material and calculate good parts per hour after setup and quality rejects. | 12% |
| Feed and Workholding System | The feeding and clamping system should prevent sheet movement, marking, slipping, and misalignment. | Vacuum or mechanical clamping design, guide accuracy, workpiece support, automatic feeding, and compatibility with small or large sheets. | Test thin, thick, narrow, and large-format sheets and record misfeed frequency and visible surface marks. | 8% |
| Control System | The control interface should support repeatable programs, parameter backup, alarms, and operator access control. | Controller type, program storage, touchscreen language, recipe management, password levels, diagnostics, and data backup. | Ask the supplier to demonstrate program creation, parameter backup, alarm history, recovery after power interruption, and operator training. | 8% |
| Automation and Integration | Automation options should be selected according to actual production volume and labor requirements. | Automatic loading, unloading, barcode or label handling, dust extraction interface, conveyor integration, and communication protocols. | Review the complete line layout and obtain an input/output list showing mechanical, electrical, and software interfaces. | 6% |
| Dust and Workplace Safety | The machine should include guarding, emergency stops, safe access, electrical protection, and effective dust-control provisions. | Fixed guards, interlocks, emergency-stop locations, electrical enclosure protection, grounding, noise data, and dust-extraction requirements. | Inspect the machine against the applicable destination-market safety requirements and request risk-assessment documentation and manuals. | 10% |
| Build Quality and Maintainability | Critical structures should be rigid, accessible for maintenance, and protected against dust and vibration. | Frame construction, linear guides, drive components, lubrication points, electrical component specifications, and maintenance intervals. | Inspect an operating machine, review the preventive-maintenance schedule, and check the availability of replacement components. | 8% |
| Quality Management | The manufacturer should use documented inspection and testing procedures throughout production. | Incoming inspection, assembly inspection, electrical testing, final acceptance testing, calibration records, and nonconformance handling. | Request sample inspection forms, factory acceptance-test procedures, calibration certificates where applicable, and corrective-action records. | 6% |
| Factory Capability | The supplier should have verifiable design, assembly, testing, and after-sales resources. | Production facility, engineering staff, testing area, subcontracting controls, installation team, and service coverage in the target region. | Conduct a video or in-person factory audit and confirm that the production site matches the contracting entity and shipping documents. | 5% |
| Documentation | Technical documentation should be complete, consistent with the supplied machine, and available in the required language. | Operating manual, electrical drawings, pneumatic diagrams, spare-parts list, foundation requirements, software backup, and acceptance criteria. | Review documents before purchase and make the approved documentation package a contractual delivery requirement. | 4% |
| After-Sales Service | Support commitments should include response times, remote troubleshooting, installation, training, and spare parts. | Warranty scope, warranty duration, service hours, remote-access policy, technician availability, training hours, and escalation process. | Obtain a written service-level agreement and contact existing users with similar machine configurations, subject to permission. | 9% |
| Lead Time and Project Control | The delivery schedule should include design approval, component procurement, assembly, testing, shipment, and installation milestones. | Production lead time, critical-path components, factory acceptance-test date, packing method, shipping documents, and delay remedies. | Use a milestone-based project schedule and link final payment to documented factory acceptance and agreed shipment conditions. | 4% |
| Total Cost of Ownership | The lowest purchase price should not be treated as the lowest operating cost. | Machine price, tooling, spare parts, energy use, dust extraction, labor, maintenance, installation, training, and expected scrap. | Compare a three- to five-year cost model using the same production volume, working hours, material cost, and service assumptions. | 10% |
| Commercial Reliability | Commercial terms should clearly define specifications, acceptance, payment, warranty, ownership of software, and dispute handling. | Legal entity, quotation validity, payment schedule, Incoterms, export capability, intellectual-property terms, and contract language. | Verify corporate registration and export records through appropriate official or independent sources and use a detailed technical annex. | 4% |
