| Machine Type | Automatic or semi-automatic rotary slotting machine for corrugated or chipboard packaging production | Select according to board format, production volume, and required automation level | The machine configuration must match the buyer’s actual packaging workflow | Confirm machine layout, process sequence, and sample production test |
| Maximum Sheet Size | Choose a working width and length that exceed the largest planned sheet size by a practical operating margin | Common industrial formats include approximately 1,200–2,500 mm sheet width and 2,000–4,500 mm sheet length | Adequate capacity reduces trimming, repositioning, and production restrictions | Run the buyer’s largest approved sheet and verify feeding stability |
| Minimum Sheet Size | Specify a minimum format suitable for small cartons and short-run orders | Often approximately 350–600 mm in the smallest feed dimension, depending on the machine design | A suitable minimum format improves flexibility for mixed product portfolios | Test small-format samples for feeding, registration, and ejection |
| Board Thickness | Adjustable pressure and tooling for the board grades used in the export project | Typical compatible thickness is about 1.5–10 mm; confirm the actual range with the tooling design | Correct pressure protects the board surface and prevents crushed edges | Process thin, medium, and thick samples and inspect slot quality |
| Slotting Depth | Tooling with adjustable slotting depth and replaceable knives | Common production settings are approximately 20–100 mm, subject to board structure and product design | Adjustability supports different carton depths and folding requirements | Measure slot depth at multiple positions on the same sheet |
| Production Speed | Variable-speed drive with stable feeding at the buyer’s target output | Typical rated speeds range from approximately 60–180 sheets per minute, depending on sheet size and configuration | Rated speed should be evaluated together with actual usable output and setup time | Conduct a continuous production run and record output, stoppages, and rejects |
| Registration Accuracy | Servo or precision mechanical adjustment with repeatable positioning | A practical target for industrial packaging work is approximately ±1.0–2.0 mm, depending on material and process | Accurate slot alignment improves folding, gluing, and final carton appearance | Measure slot position against the approved drawing using calibrated tools |
| Changeover System | Handwheel, digital, or servo-assisted adjustments with clear scales and stored settings | Tool-free or quick-lock changeover is preferred for frequent product changes | Shorter setup time reduces waste and improves small-batch profitability | Time a complete changeover between two approved product formats |
| Control System | Industrial PLC, touchscreen HMI, fault display, recipe storage, and multilingual operating interface | English interface should be available; additional languages may be specified in the purchase contract | Clear controls simplify operator training and troubleshooting in overseas plants | Check language settings, alarm messages, recipe recall, and backup procedures |
| Electrical Compatibility | Factory-configured electrical system with suitable motor protection and documented wiring | Common industrial supplies include 380–415 V, three-phase, 50 Hz; local requirements must be confirmed before ordering | Correct electrical configuration prevents commissioning delays and unsafe modifications | Verify voltage, frequency, phase, current, terminal markings, and wiring diagrams |
| Installed Power | Select motor capacity based on sheet format, tooling load, speed, and auxiliary equipment | Many medium-duty configurations fall within approximately 8–30 kW installed power | Power demand affects plant capacity planning, operating cost, and export-site installation | Record nameplate data and verify running current under normal load |
| Safety Features | Emergency-stop circuits, guarded rotating parts, interlocked access doors, overload protection, and warning labels | Safety design should be documented and adapted to the destination market’s regulations | Safety controls reduce operator risk and support workplace compliance | Test every emergency stop, guard switch, alarm, and restart-prevention function |
| Dust Management | Enclosed cutting area or prepared extraction ports with accessible cleaning points | Provide extraction airflow requirements in the technical documentation where applicable | Effective dust control protects product quality, equipment life, and the working environment | Inspect dust outlets and operate the machine with the planned extraction system |
| Tooling and Spare Parts | Replaceable slotting knives, scoring tools, bearings, belts, sensors, and electrical consumables | Include an initial spare-parts kit and a complete parts list with technical drawings | Local availability of wear parts reduces downtime after installation | Check part quantities, dimensions, material specifications, and identification labels |
| Quality Inspection | Documented factory acceptance test using buyer-approved board, drawings, and production parameters | Inspect slot position, depth, edge condition, throughput, noise, alarms, and reject rate | A repeatable acceptance procedure creates objective evidence before shipment | Approve signed test records, sample cartons, photographs, and measurement results |
| Noise and Work Environment | Low-vibration structure, balanced rotating components, and clearly stated operating noise data | Where required by local rules, verify workplace noise against the applicable occupational limit | A controlled work environment improves operator comfort and factory compliance | Measure sound level at the operator position during normal operation |
| Documentation Package | English user manual, electrical diagrams, pneumatic diagrams if applicable, maintenance schedule, spare-parts list, and test report | Documents should identify machine model, serial number, revision date, and applicable technical parameters | Complete documentation supports customs clearance, installation, and operator training | Review documents digitally before dispatch and include a printed set with the machine |
| Export Packing | Moisture protection, shock-resistant blocking, corrosion protection for metal surfaces, and clearly marked lifting points | Packing should be suitable for multimodal transport and the expected storage duration | Proper packing reduces transport damage and simplifies handling at the destination | Inspect packing photos, package dimensions, gross weight, center of gravity, and lifting marks |
| Installation and Training | Remote commissioning support or on-site service, operator training, maintenance instruction, and troubleshooting guidance | Define training hours, travel requirements, language, scope, and acceptance criteria in advance | Structured commissioning reduces ramp-up time and improves first-month productivity | Complete installation checklist and confirm trained operators can run approved samples |
| Warranty and Service | Written warranty, remote technical support, response-time commitment, and spare-parts supply process | Commercial terms commonly define a 12-month warranty from installation or shipment; contract wording must be confirmed | Clear service terms protect production continuity after international delivery | Confirm warranty exclusions, service channels, escalation contacts, and replacement-part lead times |
| Buyer Selection Priority | Prioritize board compatibility, repeatable accuracy, safety, maintainability, electrical compatibility, and total cost of ownership | Compare at least capacity, usable speed, energy demand, tooling cost, training, warranty, and logistics requirements | The most suitable machine is not always the one with the highest rated speed | Use a weighted technical-commercial evaluation sheet before issuing the purchase order |
