Selecting a case packer begins with the product and case, not with a headline speed. A technically useful request should describe the full operating range, normal production variation and the machines on both sides of the proposed equipment.
1. Define the product-handling window
Record minimum and maximum dimensions, weight, center of gravity, surface friction, rigidity and deformation risk. Provide samples that represent normal production, including difficult products.
2. Confirm the case style and pack pattern
RSC cases, trays and wraparound blanks require different loading and closing concepts. State orientation, count, layer arrangement, dividers and allowable product compression.
3. Separate nominal speed from accepted output
Compare proposals using the same product, pattern, reject assumption, accumulation condition and changeover state. The agreed FAT should use the same basis.
4. Review changeover in practical terms
Ask which settings are recipe-controlled, which adjustments use scales and which formats need dedicated parts. A fast machine with an unclear changeover method may reduce total line availability.
5. Define upstream and downstream interfaces
Product spacing, transfer height, case supply, sealing, inspection, accumulation and palletizing signals should be listed before manufacturing.
Supplier-evaluation checklist
- Sample test completed with representative products
- Approved layout and interface list
- Documented operating range and exclusions
- Written FAT method and acceptance criteria
- Spare-parts, training and commissioning scope
